Infectious inflammation of the intestine - parvovirus enteritis

Parvovirus enteritis refers to viral diseases of dogs and is manifested by vomiting, diarrhea, development in puppies of myocarditis.

This kind of enteritis is caused by a DNA-containing virus that belongs to the family of parvoviruses. The size of the viral particles is about 22 nm. This virus is resistant to organic solvents (chloroform, ether, ethanol), bile. In fecal masses and frozen parenchymal organs is maintained throughout the year. The causative agent of the disease "parvovirus enteritis" is also resistant to antibacterial agents: penicillin, streptomycin, levomycetin, neomycin, tetracycline. Under the influence of 2-3% of hot solutions of caustic sodium or potassium hydroxide, the activator is inactivated within a few minutes.

Dogs are most susceptible at an early age - from two weeks to a year. Animals older than two years are ill very rarely, and even then, the disease occurs without significant symptoms.

From patients to healthy animals, the virus spreads by contact, through organisms of flies, rats, mice, attendants and care items. In the spread of the disease, the active role is played by the virus-carrying dogs.

Significant factors in the onset of the disease are predisposing factors (poor conditions for keeping and feeding animals, the presence of helminthic invasions), surgery, vaccination, change of ownership, etc.

The incubation period in natural conditions lasts up to 10 days. In this case, under the conditions of experimental infection, this period is about 3-4 days. In young animals between the ages of three weeks to seven months, the disease often occurs in a super-structured form, the pups die in a coma for three days.

Sick animals refuse to feed, they are registered with vomiting with mucus, and sometimes with blood. At first the feces are gray, then yellow with an admixture of blood or watery with a fetid smell. Parvovirus enteritis is very often accompanied by a fever. In puppies, signs of gastroenteritis and myocarditis are observed, lethality sometimes reaches 70-80%, in adults - 5-35%. A characteristic symptom of parvovirus enteritis in dogs is the development on day 4-5 of leukopenia. The number of leukocytes in the blood decreases and ranges from 300 to 2500 T / l.

Diagnosis of the disease using serological, electron microscopic and hematological studies. Parvovirus enteritis should be differentiated from leptospirosis, plague, and infectious hepatitis.

If your pet is diagnosed with "parvovirus enteritis in dogs," the treatment has a pathogenetic character. Therapeutic actions are aimed at eliminating vomiting, dehydration (dehydration) of the body, diarrhea, acidosis, as well as secondary infection. The active detoxification and dehydration therapy is carried out using 10-20% glucose solution. The drug is administered intravenously with the help of droppers. The loss of salts is compensated by the introduction of solutions of potassium and calcium in a ratio of 2: 1. Assign antispasmodics (no-shpu, baralgin) by intravenous or intramuscular injection with an interval of 3 hours. An effective agent is 0.1% solution of atropine at a dose of 0.3-1 ml / 10 kg of body weight. This drug is administered parenterally (intramuscularly, intravenously or subcutaneously) at intervals of 3 to 12 hours. Puppies with damage to the heart muscle intravenously administered digoxin or korglukon.

To prevent the development of the disease, isolate and treat sick animals. The animal containment sites are thoroughly disinfected with an alkaline solution of formaldehyde (2% concentration). Conditionally healthy animals are vaccinated. Immunization of dogs should be carried out at the age of 2 to 12 months. Immunity lasts 12 months.

Coronovirus enteritis of dogs is a viral disease characterized by hemorrhagic inflammation of the digestive canal, dehydration and cachexia (exhaustion). The most susceptible to the disease are puppies up to five months old. Coronavirus enteritis is caused by an RNA-containing virus that belongs to the family Canine coronavinis. Treatment and prevention of this disease are identical with parvovirus enteritis.
