CANINE CONTAGIOUS HEPATITIS

It is own infect-contagious illness of the dogs, being typical example of a very characteristic illness that stayed for a long time ignored, and being confused due your symptoms with other also, like her, caused by a virus. Only in 1947 it was described for the first time as own entity, being until that time confused with Cinomose, that also attacks dogs.

Revisions of preparations previous histológicas, proceeded by Pallaske, it demonstrated that the illness already existed since a long time, however not known as entity nosológico different from other viroses.

It is that virose denominated concisely like HCC, being characterized by a hepatitis and perihepatite fibrinosa, edema of the gall bladder and in some cases for diásteses hemorrágicas. It causes the virus inclusions patognomônicas for the presence of inclusion corpuscles in the nuclei of the hepatic cells. This also the present disease in foxes, and in these they determine encephalitis, in other words, a clinical picture completely different from that that is verified in dogs, being constituted these symptoms mere exception when they happen in dogs.

Symptoms

Without any doubt the clinical picture it is a lot similar to that that you/they present the dogs when attacked by Cinomose, being just mere difference the gradation of the symptoms and lesions between an and other disease. It can come in three ways different clinics:

PICTURE

In this, in general it is not the disease diagnosed except after the death of the animal, due your evolution fast ultra, being the found animals died in the morning after quick signs of disease in the previous night. In these cases, almost always, they suspect the proprietors of the animals of your poisoning.

I SQUARE SHARP

The animals also show apathy, stupor and lack of appetite, and the times intense thirst. The feverish curve exhibits two and at the most three picks, however none of them reaching the maximum of your previous pick. There is in certain way, likeness with the thermal curve denominated bicuspid that is also verified in Cinomose. They are also verified conjunctivitis and hiperemia epiescleral, distinguishing however of that festering and so resistant relevantemente to every treatment that happens in Cinomose.

To the end of some days he/she settles in the cornea, an opacity of that mucous membrane, unilateral comumentemente, which coincides with new feverish access. That turvamento of the cornea is slow, and rarely lasting long up to 3 weeks, and resistant to all and any specific treatment. In the breathing organs they are noticed different tonsillitis degrees, lacking in these that picture pneumônico of Cinomose. The interior of the throat (fauces), he/she is red and inflamed, presenting the animals sick difficulties to swallow, what motivates vomits for action reflexa. Especially painful it is the palpação of the area of the appendix xifoide in sick animals for HCC, reacting the violently that exploration those animals attacked by the disease. Jaundice rarely exists.

Worthy of having in bill, for the effectiveness in all the cases, it is the blood test. At the beginning they are proven as in all the viroses: leucopenia, that is turned into leucocitose when lowering the fever. Therefore the morphologic investigation of the blood lacks of importance. Only in the initial phase of HCC he/she comes the leucopenia (relative decrease of the globules of the white lineage - leucócitos), what is different from the picture when it is Cinomose, being in this since your present beginning Leucocitose (I increase relative of the globules of the white lineage - leucócitos). In the however, tends longer duration, also in HCC the leucocitose is present. The mechanism of coagulation of the blood, in the animals attacked by HCC, it is found completely altered, with increase of the time of sangria, what doesn't happen with Cinomose. The speed of sedimentação of the blood also meets increased. In general, the suspicion of HCC exists when they sicken animals with less than 8 weeks and when the symptoms appear suddenly, and a lot of times violently. They are present fever, tonsillitis, enfarto of the cephalic lymphatic ganglions, included tonsils, conjunctivitis serosa and not festering (with rinites) besides inconstant albuminúria. It is unfavorable the prognostic when presents jaundice and subnormal temperature (hypothermia). The turvamento of the cornea, is in most of the cases of light course. Special importance has the increase of the size of the liver (hepatomegalia), besides they express pain the animals in that palpação, also presenting the spleen size increase (esplenomegalia).

Treatment

He has special value the serum hiperimune (range-globulins), when precocemente applied, same being treated of mixed serum, as the for now existent in the market of veterinary products. It should also be preceded to the symptomatic treatment, with restorative medication for the liver, besides applications parenterais of sôro-glico-physiologic in discharges doses, besides vitamins of the compound B. The vitamin K, suitable to improve the coagulation of the blood, your action it still depends still on more effective demonstration in that disease.

Prevention

They exist at the market of products veterinary, several vaccines with preventive indication against HCC, being particularly efficient those manufactured by German Bayer, as the call Candur S-H-L (triple: Cinomose, Hepatitis and Leptospirose), that unhappily difficultly found at the market. To informative title, the animals that you/they get to surpass the disease, coming the if they cure, they are bearers of the virus and eliminating him/it for several months, being able to work as circulators for others you encourage not properly immunized.
