Causes of Canine Parainfluenza|Diagnosis|Prevention and Treatment

Causes of canine parainfluenza:

The pathogen is a parainfluenza virus belonging to the family Paramyxoviridae, a subgroup of the genus Paramyxovirus. The nucleic acid type is single-stranded RNA, and the virus particles are pleomorphic and generally spherical. The main way of infection is the respiratory tract, and the respiratory secretions can infect other dogs through air dust, and can also be transmitted through direct contact. During the infection period, dogs may develop secondary bacterial infections due to reduced resistance. Newly purchased puppies are very susceptible to the disease under stressful conditions such as sudden changes in the environment, cold and damp, overcrowding, and sudden temperature changes.

Diagnostic criteria for canine parainfluenza:

The clinical manifestations of canine respiratory infectious diseases are very similar and difficult to distinguish. Cell culture is the best method for isolating and characterizing canine parainfluenza virus. In addition, retrospective diagnosis can also be made by checking whether the serum antibody titer has increased by serum neutralization test and hemagglutination inhibition test.

Prevention measures for canine parainfluenza:

Prevention can be vaccinated with a single vaccine or a five-combined vaccine, and there is no specific medicine for treatment, mainly symptomatic treatment and prevention of secondary infection.

1. Prevention of secondary infection: intramuscular injection of chloramphenicol 10-30 mg per kg of dog body weight, or 5 mg of tylosin per kg of dog body weight, or 7 mg of tetracycline per kg of dog body weight.

2. Antitussive: intramuscular injection of antitussive agent aminophylline 10 mg per kilogram of dog weight.

3. Anti-inflammatory: Dexamethasone 0.25-2 mg per kg of dog body weight, 1 day.

4. Improve resistance: Give a large amount of vitamin C, 200-400 mg per day, to improve resistance.

Treatment for canine parainfluenza:

1. Hyperimmune serum can be injected into affected dogs. Intravenous infusion of canine hemoglobulin can improve the dog's resistance.

2. For sick dogs with elevated body temperature, antipyretic drugs can be taken orally. For sick dogs with severe cough, Huatan Zhike Granules can be used to alleviate the condition. When using traditional Chinese medicine, you can choose antiviral oral liquid, Shuanghuanglian, Banlangen, etc.

3. When dogs are infected with canine parainfluenza virus, they are often secondary to infection with Bordetella bronchiseptica, Mycoplasma, etc. Therefore, antibiotic drugs should be used to prevent secondary infection, so as to alleviate the condition and promote the early recovery of sick dogs.
