Anthrax, one of the most dreaded zoonotic diseases is characterized by sudden death in cattle. It is normally considered that oozing of unclotted tarry blood from the external natural orifices is suggestive of Anthrax. Here we report two cases of anthrax in cattle wherein bleeding in any form was not detected. One was from a cross-bred cow and another from a bullock, which were brought for necropsy examination with a history of sudden death from the nearby slaughter house. The carcasses were bloated and rigor mortis was partial. The peripheral blood smear examination from both the cases revealed the presence of truncated, capsulated, short rods of Bacillus anthracis. This clearly warrants the need for examination of peripheral blood smear examination before attempting autopsy, as anthrax in an occult form may be present in the cases, which may definitely pose a zoonotic risk.

The article reports on the research of hepatocellular carcinoma and cholangiocellular carcinoma in a duck.

The article focuses on the clinical report related to the detection of urine retention and crystalluria in a pug breed of dog that was presented for necropsy. It states that massive infiltration of polymorphonuclear cells are revealed through haematoxylin and eosin staining of the urinary bladder tissue sections. It mentions that urolithiasis, urine retention and bacterial invasion resulted in the death of the animal.

The article presents a case study of chronic hepatitis in a captive poisonous Russell's viper in India. A detailed necropsy of the dead snake revealed chronic hepatitis coupled with intestinal helminthosis affecting the kidneys. Histopathological examination of Haematoxylin and Eosin stained liver sections revealed massive infiltration of lobules by chronic inflammatory cells which caused the viper's death.
