canine viral Enteritis or parvovirus

As very small person in charge of the well-known one indicates his Latin name in parvovirus is a virus and so feared called disease Parvovirosis.

The Parvovirosis affects canine young people as of the 6 weeks when losing the maternal immunity, is infrequent in adult animals because or vaccination or subclinical infections is immunized by.
The approximate period of incubation is of 5 days.
The contamination source is the fecal matter of the animals that have contracted the infection. It can have great amount of virus in fecales lees of the animals that suffer the disease. The virus is resistant under extreme climatic conditions and can survive during long periods, but he is sensible to the hipoclorito of sodium (lavandina) reason why recommends the disinfection like environmental treatment in caniles, infected bottoms of perreras and territories.
Parvovirus is not contagious to the man nor other domestic animal species.

The presentation but frequents is the digestive one producing a viral hemorragica gastroenteritis, the virus infects the intestinal cells (the enterocitos) and is talked back producing necrosis and cellular death, responsible mechanism sintomatologia.
The frequent symptoms but estan mentioned by chronological order of presentation:

* Decay and depression (first days)
* Anorexy (lost of the appetite)
* Fever (between 40 and 41 Cs)
* Vomits (frothy, like clear of beaten egg)
* Diarrea with blood
* Dehydration (due to the vomit and the diarrea)

The small cachorritos but are those that suffer more of shock and death that can happen in a matter of days after to have declared the disease. This disease has a high morbidity and mortality, with tratamiemto the mortality indices are reduced remarkably.

The veterinarian can give his initial diagnosis being based on the clinical signs, but single after to have taken in consideration the other causes that could cause I vomit and the diarrea (diagnosis differential), often is necessary to confirm the diagnosis by means of laboratory test.

The disease is of fast incubation and acute course, that is that the virus kills to the animal in the first ten days, if it does not do it, the puppy forms immunological defenses and destroys the virus. If the puppy as of the moment that makes the first deposition with blood, survives 7 days is very probable that it survives, being very critical the 4 first days that is when, generally, the fatal outcome, S.A. takes place quarter day the puppy lets vomit, walks, begins to move the tail, is hopes of which it is saved, but is a very serious disease that never knows certainly that it is going to happen in those ten days.

Another form of parvovirus much less frequents is the inflammation of the heart (miocarditis). This presentation happens without digestive sintomatología and the viral infection happens in the muscular cells of the heart (myocardium), it affects very young animals (weeks), and is a cause of sudden death, the puppies that survive can be with some permanent cardiac defect.

Like in almost all the viral infections there are specific treatments no all are symptomatic, it consists mainly of fighting the symptoms for example to revert the dehydration, replacing the lost liquids and electrolytes (ej. serum: Ringer lactate), controlling by means of appropriate medication vomits and the diarrea and avoiding the secondary infections with the antibiotic administration. It is recommended to prevent the disease with the respective vaccines that are applied in the puppy as of the 45 days of life and to take the sanitary plan to the day.
