Abstract

A female beagle dog with no history of previous illness was reported to be died of Viper snake bite early in the morning. The dog showed restlessness and respiratory stress before death. Complete post mortem examination was conducted and samples of skin, lung, heart, liver, spleen, intestine, stomach and kidney were collected in neutral buffered 10% formalin for histopathological examination. Gross examination revealed fang marks and haemorrhages over the face and on the head. Lungs were congested, haemorrhagic and rubbery in consistency. Heart and liver were congested and liver was haemorrhagic and dark in colour. Gall bladder was haemorrhagic. Spleen revealed focal ecchymotic haemorrhages. Kidneys were congested and haemorrhagic. Mucosa of stomach and intestines was congested and mesenteric blood vessels were also severely congested. Histopathologically, lungs revealed congestion, haemorrhages and an interstitial inflammatory reaction. Heart revealed myocardial congestion and haemorrhages. Liver revealed dilated portal vein, sinusoidal congestion, degeneration and necrosis of hepatocytes and cytoplasmic vacuolation. In Kidneys, there was acute tubular injury, haemorrhages, and mild infiltration of inflammatory cell in the interstitial space. The findings revealed that the viper snake bite altered vascular blood flow and permeability resulting in shock and death of the dog due to hypoxia.
