Parainfluenza in dogs is not fatal, but unpleasant. Parainfluenza in dogs - how do we treat our Labrador Retriever? Stage of disease progression

Flu is very dangerous and serious illness person. Every winter is marked by his victorious march through cities and towns. Oddly enough, our pets also have its “analogue”. This is parainfluenza in dogs. Of course, this is far from the flu in its original sense, but this disease can cause a lot of problems. In particular, with only one contact with a sick animal, your dog will almost certainly get sick. The only consolation is that there are practically no deaths.

The disease is viral in nature, caused by a pathogen from the paramyxovirus family. In general, there are many questions with this. The fact is that there is still debate among veterinarians and microbiologists about the specific pathogen. So far, everyone agrees that the pathology should be recognized as some general case of damage to the upper respiratory tract a whole complex of pathogens (including bordetellosis). Respectively, specific treatment They haven't figured it out yet either. There is only general, symptomatic therapy that “suppresses” the main symptoms.

Let us immediately put to rest those owners who do not know whether this virus is contagious to humans. No, it does not pose any danger to you and your household, so there is no need to worry about this. Of course, this does not eliminate the need to urgently take the dog to veterinary clinic.

It is important to make one note here. This vaccine helps specifically against paramyxovirus, but does not prevent the disease if other pathogens are also involved in the infection. I would like to say once again that the vaccination plan must be drawn up by an experienced veterinarian, who can recommend other polyvalent vaccines, the use of which is necessary specifically in your case.

Important! Vaccination reliably protects the animal from the disease, but does not prevent the presence of the virus itself in the body! Simply put, even vaccinated dogs at shows may well be carriers of the infection!

Therefore, it is mandatory to vaccinate all your dogs. This is done once, once a year. This will not take much time, but it will help preserve the health of your pet and your own finances, since treatment of advanced and severe forms is long and expensive. Moreover positive result is not guaranteed in all cases.

Canine parainfluenza is a highly contagious infectious dangerous respiratory disease that affects the respiratory tract of animals. The inflammatory process affects the mucous membranes of the respiratory tract, leading to disruption of the functioning of the respiratory system.

Dogs of all breeds are susceptible to the disease, regardless of age. Parainfluenza is especially dangerous for small puppies with immature immune system. In veterinary practice, the disease is most often diagnosed in early spring, autumn and winter.

Etiology

The causative agent of canine parainfluenza is a virus of the paramyxovirus family (strain CPIV). In addition, the causative agent of the disease is localized in the regional lymph nodes of the dog. The parainfluenza virus is localized in the epithelium of the nasal cavity, larynx, trachea, bronchi, and nasopharynx. In some cases, the virus is isolated from the lungs, intestines, and spleen.

Pets become infected by airborne droplets, in close contact with infected individuals. Parainfluenza is often called “kennel disease”, “kennel cough”, since dogs most often are at risk when kept in groups in kennels and enclosures.

The danger of contracting a dangerous respiratory disease occurs when the body’s resistance decreases, in weakened animals, puppies with immature immunity, as well as in dogs kept in unfavorable conditions. Dogs can catch parainfluenza through contact with homeless and stray animals, at exhibitions, competitions, and in general dog walking areas.

Get infected respiratory infection a dog may be under stress, for example, when there is a change of owner, since stressful situations significantly weaken the body and reduce immunity. Infection of a dog with parainfluenza is also possible during transportation in violation of the rules for transporting dogs. In most cases, the disease is diagnosed in unvaccinated, unvaccinated animals of any age.

Symptoms, clinical manifestations of canine parainfluenza

The incubation period for dogs infected with parainfluenza ranges from several days to a month. The intensity of the manifestation depends on the general physiological state of the animal, the state of immunity, and conditions of detention. The duration of the disease, as a rule, is 7-10 days and ends with recovery if effective treatment was prescribed in a timely manner.

In weakened dogs, the disease can provoke serious complications, which can manifest themselves in the form of pneumonia, bronchitis, and chronic catarrh of the upper respiratory tract. With a protracted form of canine parainfluenza, the disease can develop into virus carriage. In this case, the dog does not have outwardly noticeable characteristic clinical symptoms, but the animal is a carrier of a dangerous virus.

In newborn puppies, the parainfluenza virus can affect various organs and systems, ending in viremia, in which the pathogen is localized in the cellular structures of the bloodstream. Puppies from ten days of age are susceptible to infection.

The main clinical manifestation of parainfluenza in dogs is a lingering dry cough, attacks of which intensify during exercise.

Symptoms of parainfluenza in dogs:

a sharp increase in temperature in the first days after infection to 40-40.5 degrees;

decline physical activity, lethargy, drowsiness, apathy;

loss of appetite, refusal to feed, extreme thirst;

violation respiratory function, shortness of breath;

serous, serous-purulent discharge from the eyes, nose;

pallor, anemia of the mucous membranes, redness of the conjunctiva.

In severe cases, attacks of vomiting, diarrhea, and pneumonia are possible. During auscultation, strong wheezing and whistling are heard in the lungs, and pain in the sternum is also noted. The disease occurs in the form of tonsillitis and pharyngitis. Less commonly, bronchitis and tracheitis are diagnosed in dogs against the background of illness.

Important! In dogs, parainfluenza is often a secondary infection that worsens against the background of other infectious viral diseases. Parainfluenza infection is often accompanied by other respiratory diseases– adenovirus infection, canine distemper virus, canine reovirus, herpes virus.

If you contact a veterinary clinic in a timely manner, the prognosis for the disease is favorable. The main thing is not to delay if it gets worse general condition, manifestations of the first clinical symptoms parainfluenza in a dog with a visit to a veterinarian!

Diagnosis of parainfluenza in dogs

Diagnostic techniques are based on a general clinical examination, anamnesis data, and a series of laboratory research and analyses, carrying out special test systems.

It is very important to promptly prescribe effective, correct treatment when diagnosing parainfluenza infection in dogs. Unfortunately, antivirus medications There is no drug available for the treatment of respiratory tract infections. For dogs, a veterinarian prescribes symptomatic medications, antibacterial agents wide range actions.

Sick dogs as additional treatment Immunomodulators, mineral-vitamin complexes, mucolytics, and expectorants are prescribed. If necessary, four-fingered patients can be prescribed a special therapeutic diet, homeopathic remedies. The course, duration, and treatment regimen are prescribed by the attending veterinarian.

sick pet it is worth protecting from drafts, avoiding hypothermia, feeding with warm, easily digestible food, medicinal food, giving herbal teas, decoctions of medicinal herbs.

Prevention of parainfluenza in dogs

As a preventative treatment, owners should create favorable conditions for your beloved pets, avoid prolonged hypothermia of animals during walks in damp, cold weather. Fence pet from stressful situations. If the dog is kept in an enclosure, take care of a warm, cozy home for your pet. Do not allow your pet to come into contact with stray animals.

It is equally important to strengthen the dog’s immunity, give vitamin and mineral complexes, and monitor the quality of the diet. The dog's diet must be balanced in terms of protein, fat, carbohydrates, macro- and microelements. Special attention Pay attention to the nutrition of puppies, young animals, pregnant and lactating dogs.

As a specific prophylaxis, there are prophylactic associated vaccines containing parainfluenza antigen, as well as monovaccines that are administered intramuscularly or subcutaneously. Serums against parainfluenza in dogs will help strengthen protection.

If the characteristic clinical symptoms described above appear or the dog’s general condition worsens, immediately take your pet to a veterinary clinic.

Your dog is sick and you don’t know what to do? The first thing is to calm down, and then soberly assess the situation and pay attention to all the symptoms of the disease. Parainfluenza in dogs has some. It is very easy to catch and difficult to cure. The disease in a pet is not dangerous for people, so isolate four-legged friend not necessary. But it should be treated immediately.

Parainfluenza is caused in dogs by a virus from the paramyxovirus family. Infection occurs by airborne droplets.

A pet can become infected with parainfluenza at a dog show.

Therefore, a sociable animal is at greater risk of getting sick than others. You should not allow your pet to communicate with many familiar and unfamiliar dogs while walking. Such carelessness can turn into illness.

In addition, a dog can get sick by visiting a dog show, because there are usually a lot of people like him there. And a crowd of animals is a great success for viruses!

Main symptoms of the disease

If a dog is not vaccinated, it can get parainfluenza at any time.

What to look for? Of course, on the pet’s activity. Every owner knows how the animal usually behaves. If the dog is sad, has stopped following its favorite commands, or doesn’t even want to go for a walk, perhaps she was sick.

Parainfluenza causes damage to the upper respiratory tract, so you should listen to the animal's breathing. If you have a cough that is rough and prolonged, it may be parainfluenza. It is the cough in this disease that is characteristic symptom. that the owner begins to panic. occurs with any exertion, even a short jog leads to an attack of protracted dry cough.

Cough is one of the symptoms of parainfluenza.

initial stage

On initial stage The pet’s appetite does not decrease, which misleads the owner. “If he eats well, he is healthy,” that’s what inexperienced dog breeders try to think. Experienced ones urgently take the pet to the veterinarian.

At the initial stage of the disease, the dog’s appetite does not decrease.

The body temperature rises slightly, which also raises doubts about the animal’s illness. “Maybe I’m just overheated or tired,” people reassure themselves.

Disease progression

As the disease progresses, the dog's condition worsens, she begins to refuse food, but is tormented by thirst.

Therefore, a bowl of warm drink should be nearby. An infection of the eyes occurs: they become sour and look sloppy. After waking up, it is difficult for the dog to open his eyes, as the eyelashes stick together tightly purulent discharge. Visible from the nose serous discharge.

When does a dog have loose stool, it ceases to control the process of defecation, which means that pathogens have reached the stomach. This condition threatens rapid dehydration and exhaustion. If you do not respond with adequate treatment, the animal dies .

The progression of the disease is manifested by loose stools.

Symptomatic treatment

The drug Doxycycline is given to the dog for 5 to 10 days.

There are no specific antiviral agents for the treatment of parainfluenza in dogs.

All manifestations of the disease are the result of an associated secondary infection. Therefore, the treatment regimen looks something like this:

Antibiotic therapy . Broad-spectrum antibiotics are used. It can be: Doxycycline, Minocycline, Metacycline hydrochloride. The dose of the drug is selected based on the weight of the animal. Treatment usually takes from 5 to 10–12 days.
Treatment with antibiotics is therefore mandatory hepatoprotective agent LIV-52, Karsil .
To protect organs gastrointestinal tract use probiotics and enzyme preparations .
To strengthen the body's protective functions, they begin to carry out vitaminization of the dog .
You can increase your immunity immunostimulants and immunomodulators .
Cough requires appointment expectorants and drugs with mucolytic action .
Eyes can be washed weak manganese solution .
For nasal instillation, you should not use the same drops that are used for people. Can be used folk remedies, for example, aloe or beet juice.

Prevention

The most correct solution– vaccinate your pet. Only timely administration of the vaccine can guarantee the dog’s safety even among a pack of dogs.

To prevent the disease, vaccination should be carried out.

If it is impossible to vaccinate the animal, you will need to monitor it as closely as possible while walking, avoiding contact with other animals. Even if a familiar dog who has everything wants to play with your pet, this does not guarantee safety. Vaccinated dogs do not get sick themselves, but can become carriers of parainfluenza infection.

Particular attention is paid to the dog's nutrition. Everything should be present in the diet essential vitamins and minerals.

Disinfection of the premises must be carried out constantly. Floors must be washed with disinfectants. After a walk, the animal’s paws are washed in a basin with warm water and soap, and then wiped dry.

Parainfluenza-3 large cattle(PG-3 cattle) (transport fever of cattle, parainfluenza-3) – acutely contagious viral disease, mainly calves, characterized by fever, conjunctivitis and catarrh of the upper respiratory tract, in severe cases with damage to the lungs.

Historical reference. This disease was first described in the USA in 1932. Scott and Farley, who established the role of Pasteurella in the etiology of the disease. A new understanding of the causative agent of this disease changed in 1959, when researchers isolated a virus from sick calves that was similar in antigenic structure to the human parainfluenza virus-3 (PG-3). In the USSR, PG-3 was installed in 1968. To date, PG-3 has been registered in all countries of the world where industrial livestock farming is developed.

Economic damage with parainfluenza-3, it consists of a shortage of offspring, products and costs for carrying out veterinary and treatment and preventive measures.

Pathogen- An RNA-containing epitheliotropic virus from the paramyxovirus family, has hemagglutinating and hemolytic effects, as well as hemadsorption properties.

Size 150-250nµ. The virus has pronounced antigenic activity and has two types of antigens that differ in properties and specificity: ribonucleoprotein, or S-antigen, and surface V-antigen. The virus is not resistant to high temperatures: at 56°C the virus dies within 1 hour, at 36-37°C - after 5 hours, at the same time the virus is very resistant to action low temperatures, maintaining its virulence during 4-fold freezing and thawing.

Ultraviolet rays have a detrimental effect on the virus; it is also quickly inactivated in an acidic environment. Solutions of Lysol, formaldehyde, bleach and other disinfectants in generally accepted concentrations are used as disinfectants.

Epizootic data. Typically, calves become ill with parainfluenza-3 from 10 days to a year. Adult animals are also susceptible, but their parainfluenza is asymptomatic. The source of the infectious agent is sick animals. Those who release the virus with exhaled air and nasal discharge, also with vaginal discharge, especially during periods of severe clinical signs, as well as recovered animals. Cattle serve as the reservoir of the pathogen in nature.

Conducted serological studies Wide circulation of the virus has been established among healthy cattle of all age groups (80-100%), as well as in sheep, pigs, horses, buffaloes and many species of poultry. The presence of widespread carriage of the pathogen determines its constant and widespread preservation in nature. Predisposing factors for the development of parainfluenza-3 in cattle are overheating, hypothermia, crowded housing, vaccinations, long-term transportation (which is why the disease received the additional name “transport disease”) and other stresses. Parainfluenza-3 often occurs in the form of mixed infections with other viruses and bacteria.

The disease occurs when animals are kept in stalls on farms with a high concentration of calves, and especially when stocked with an uneven immune background, among which there are virus carriers. Severe disease is observed among calves kept in rooms with high humidity and poor ventilation.

The incidence of parainfluenza-3 in calves is usually high (70-80%), mortality - from 2 to 15-20%. Animals are most often infected aerogenously. But the nutritional route of infection cannot be ruled out. Transmission of the virus is possible through sexual contact, as it is found in semen, vaginal secretions, and tissues of aborted fetuses.

Pathogenesis. The pathogenic manifestation of the PG-3 virus is due to its tropism for the respiratory organs. When animals are infected by airborne droplets, the virus penetrates into the cells of the mucous membrane of the upper respiratory tract, where it actively, due to the enzyme neuraminidase and hemagglutinin, penetrates into epithelial cells and quickly reproduces there. After a large number of Virions are released onto the surface of the mucous membranes and enter the mucus, resulting in the destruction of the most important protective barrier for the body - the mucous membrane, creating favorable conditions for the development of secondary infection. The multiplied virus and cell decay products partially penetrate into the blood, contributing to the occurrence of general intoxication of the body. Disruption of the epithelium of the upper respiratory tract, as well as a decrease in the phagocytic activity of leukocytes under the influence of the parainfluenza virus-3, contribute to the activation of bacterial microflora and, against this background, the occurrence of complications.

IN lung tissue the virus causes characteristic epithelization of the alveoli and small bronchi, as well as inflammatory process in peribronchial tissue. As a result of exposure to toxic products formed during inflammation and the layering of accompanying microflora inflammatory reaction may spread to entire lobes of the lung and regional lymph nodes.

Hyperacute course usually observed in calves up to 6 months of age and is accompanied by severe depression of the animal, coma and death of the animal during the first day.

Acute course- in the first days of the disease in sick calves, body temperature rises to 41-42 ° C, appetite decreases, a dry cough appears, discharge from the nasal cavity, often from the eyes, sometimes diarrhea appears in sick animals, the pulse increases to 120 beats and breathing to 84 in a minute. Animals quickly lose weight, their coat becomes dull and disheveled. At severe course diseases in animals, serous conjunctivitis and rhinitis first develop, often accompanied profuse drooling, high temperature body and diarrhea.

Subacute course characterized by the same symptoms as acute, but they are less pronounced; The body temperature of sick animals increases slightly. Recovery in subacute cases occurs within 7-10 days.
With complications of PG-3 (chronic bronchopneumonia), which occurs quite often in industrial conditions, the disease takes chronic course. Sick animals are inactive and exhausted. When moving, they cough and a thick viscous exudate is released from the nasal openings; in the lungs upon auscultation - large, medium-fine bubble rales; In the apical lobes of the lungs, auscultation can reveal the sound of crepitus (inflammation of the lung tissue). Some calves may develop enteritis accompanied by diarrhea. In sick cows, intrauterine infection of the offspring, abortions, or the birth of non-viable calves can be observed.

Pathological changes are mainly observed in the apical, cardiac and diaphragmatic lobes of the lungs (usually the anterioinferior zones). The affected areas of the lungs are enlarged, blue-red or gray, often with zones of emphysema along the periphery. IN chest cavity, serous or serous-fibrinous exudate accumulates in the pericardium, and on the surface of the pericardium, epicardium and pleura there are thin deposits of fibrin, hyperemia of the mucous membrane and mucopurulent exudate in the trachea and bronchi, signs of rhinitis, laryngotracheitis. The retropharyngeal, bronchial and mediastinal lymph nodes are sometimes enlarged, hyperemic, moist on the cut surface, sometimes with foci of necrosis. In parenchymal organs we find granular dystrophy. In addition to hemorrhages, erosions and ulcers are observed on the mucous membrane of the abomasum. The intestinal mucosa is swollen, with hemorrhages.

Diagnosis and differential diagnosis . The basis for making a diagnosis is the analysis of epizootiological, clinical and pathological data with the mandatory conduct of laboratory tests: virological and serological using specific diagnostics. For these purposes, for intravital diagnostics, 5 to 8 samples of nasal and eye discharge from animals with clinical manifestations of the disease, as well as blood serum from recovered animals are sent to the laboratory; for posthumous laboratory diagnostics guide fragments of the retropharyngeal, mediastinal lymph nodes, nasal septum, larynx, trachea, lungs, selected no later than 2 hours after slaughter and placed in a thermos with ice.

For diagnosis, the method of immunofluorescence, RTGA, ELISA and PCR diagnostics is used.

Parainfluenza is differentiated from, adenovirus infection, viral diarrhea, respiratory syncytial and streptococcal infection by conducting virological and serological studies.

The diagnosis of parainfluenza-3 is considered established in one of the following cases: a 4-fold or more increase in antibody titer in paired blood sera; isolation of the virus from pathological material and its identification.

Immunity and specific prevention. Animals that have recovered from parainfluenza remain immune to the disease for 3 months. re-infection. An important factor in immunity is the local immunity of the cells of the mucous membrane of the respiratory organs, caused by the formation of secretory antibodies and interferon, which are often detected in a higher titer after intranasal vaccination with a live virus than after subcutaneous vaccination with an inactivated virus. Humoral antibodies after vaccination remain in animals for 6-12 months. Calves born from immune cows receive antibodies through colostrum. Vaccination of calves is more effective during the period of extinction of maternal antibodies.

For specific prevention of PG-3, live inactivated vaccines. However, the latter have not yet been found in production conditions wide application.
Live vaccines are more effective than inactivated ones. The former are prepared from attenuated strains of the bovine parainfluenza virus or the sheep strain of this virus. Highly efficient combination vaccines from live attenuated strains of parainfluenza, diarrhea and killed Pasteurella viruses, as well as bivalent vaccines against parainfluenza and infectious rhinotracheitis. IN Lately Live combination vaccines containing attenuated strains of PG-3, IRT, VD-BS and adenovirosis viruses have increasingly begun to be used. Sometimes Pasteurella antigen is added to such vaccines.

In the Russian Federation, parainfluenza-3 is used to prevent parainfluenza-3 in agricultural enterprises. live vaccine from the avirulent strain “Paravak”, as well as the bivalent dry culture-associated vaccine “Bivak” for the simultaneous prevention of parainfluenza and infectious rhinotracheitis in cattle.
After 2-time vaccination of calves, the duration of immunity is at least 6 months.

To prevent parainfluenza-3, the Federal State Institution ARRIAH has developed mono and associated inactivated vaccines that form active immunity for a period of 6 months within 14-21 days after vaccination.

Treatment. Treatment of the disease is effective only in acute and subacute cases of the disease.
In order to increase the overall resistance of the body, we provide sick animals with complete, balanced diet feeding and create normal zoo-hygienic conditions of detention. Sick animals are prescribed complex treatment using specific hyperimmune serums and symptomatic agents. To prevent complications from bacterial microflora, broad-spectrum antibiotics (tetracyclines, macrolides and modern cephalosporin antibiotics) and sulfonamide drugs are used, taking into account sensitivity to them pathogenic microflora respiratory tract. In production conditions, combinations of two or more drugs or ready-made combination antibiotics (tetraolean, tetraoleandomycin, oleandovetin) are most effective. From symptomatic remedies drug therapy use drugs that tonic the cardiovascular system (camphor, caffeine-sodium benzoate, glucose), diuretics (mercusal, potassium acetate), expectorants (ammonium chloride, potassium iodide), bronchodilators (theobromine, theophylline), etc. For the purpose of normalization metabolic processes In animals, trivitamin is administered intramuscularly in a dose of 5 ml. Not bad healing effect veterinary specialists on early stages the development of pneumonia is obtained from novocaine blockade right and left stellate node. In the room where sick animals are kept, aerosol disinfection is carried out using SAG devices once every 3-5 days. For this purpose, a 5% solution of chloramine B, a 40% solution of lactic acid, a 3% stabilized solution of hydrogen peroxide and a number of other drugs are used.

For therapeutic and prophylactic purposes in PG-3, the drug mixoferon (from the group of interferons) is used. Which protects the cells of the animal’s body from the effects of the virus.

Measures to prevent parainfluenza-3 in cattle.

Preventive measures to prevent parainfluenza-3 in cattle consist of protecting the farm (farm) from the introduction of the infectious agent, carrying out a set of measures aimed at increasing the general resistance of animals, strict compliance with the current veterinary and sanitary rules for specialized farms (farms and complexes), timely diagnosis disease, destruction of the virus in external environment(preventive disinfection).
To protect the farm from the introduction of parainfluenza-3, it is necessary to stock livestock farms with healthy animals from the reproductive farms assigned to them, which are safe from infectious diseases.
Specialized farms (farms and complexes) are assigned supply farms where there are no animals with clinical manifestations diseases. The room is filled with animals in compliance with the “free-occupied” principle with calves of the same age for 3-5 days. Calves from one supplier farm are placed in separate sections (pens). Replenishment of groups and transfer of animals from one group to another, as well as the introduction of animals obtained from private farms of the population, are prohibited. Animals newly arrived at farms and complexes must be quarantined for 30 days.
At supplying farms, at least 7 days before transporting calves to a complex or another farm, they are subjected to preventive vaccination against parainfluenza-3. Animals are vaccinated with the Paravac virus vaccine in accordance with the instructions for its use. If animals have antibodies to the AI-3 virus and infectious rhinotracheitis, they are vaccinated with the associated Bivak vaccine.
Animals are delivered to the complex by special vehicles.
Breeding animals imported are quarantined for 30 days and used in strict accordance with current Instructions“On veterinary and sanitary measures when importing animals, products and raw materials of animal origin and fodder into the USSR.”
Specialized farms (farms and complexes) are transferred to the operating mode of closed-type enterprises, which provides for the division of the farm territory into production and economic zones, compliance with sanitary rules service personnel with a change of clothes, shoes and treatment in sanitary checkpoints, prohibition of visits to farms by unauthorized persons, installation of disinfection barriers, observance of personal hygiene rules.
The necessary microclimate is maintained in livestock buildings and preventive disinfection is carried out regularly.

Measures to improve the health of farms against parainfluenza-3 in cattle.

When a diagnosis of parainfluenza-3 is established, the farm in accordance with the order of the Ministry of Agriculture of the Russian Federation No. 476 dated December 19, 2011. “On approval of the list of contagious, including especially dangerous, animal diseases for which restrictive measures (quarantine) can be established.” By decree of the Governor of the region, the region is declared unfavorable for parainfluenza-3 and restrictions are introduced and measures are taken to improve the health of the livestock in accordance with the approved plan.

Sick animals are isolated in separate sections and treated with hyperimmune serum, nonspecific globulin or convalescent serum. At the same time, antibiotics, sulfonamides and nitrofuran drugs are used. In vacated rooms (sections), disinfection is carried out before mechanical cleaning. The remaining animals are vaccinated with the Paravac virus vaccine, and in the presence of an infection mixed with RTI, with the associated Bivak vaccine according to the instructions for its use.

The same applies to vaccinations of all mother cows.

Restrictions are introduced on the farm (on the farm), according to which it is prohibited:

importation into the farm (farm) and export of animals to other farms.
regrouping of disadvantaged livestock.
visits to dysfunctional farms (premises) by persons not involved in animal care.

It is allowed to transport animals for slaughter to a meat processing plant on specially equipped transport; animal corpses are disposed of.
Disinfection of machines, care items, equipment and Vehicle on a dysfunctional farm (indoors) is carried out in accordance with the current Instructions for veterinary disinfection, disinfestation, disinfestation and deratization.
Managers, zootechnical and veterinary specialists of the farm must take measures to eliminate violations in the feeding and maintenance of animals that aggravate the course of the disease.
Carcasses of killed animals after ripening of meat and in the absence of degenerative changes released without restrictions. If inflammatory and necrotic foci are detected on the mucous membrane of the nasal cavity, trachea, lungs, and gastrointestinal tract, these organs are subjected to technical disposal.
The farm is declared free from parainfluenza-3 and restrictions are lifted 14 days after the last case of recovery or slaughter of a sick animal. Before restrictions are lifted, the premises where sick animals were located are subjected to final disinfection, and a report is drawn up.
