The survey on lesions in lungs, livers, stomachs and intestines of dogs infected CDV disease

Abstract

Autopsy for 10 dogs infected CDV disease was carried out at the Veterinary Clinic, Can Tho University, from January to August 2020 to evaluate the damage level of the lung, liver, stomach and intestine in the infected dogs. The studied results showed that the CDV infection dogs suffered with
different gross lesions, such as: bronchitis (70%), pulmonary congestion and hemorrhage (60%), graying liver and necrosis foci (30%), intestinal inflammation and hemorrhage (100%), stomach inflammation and hemorrhage and gas filling (50%), liver swelling, hemorrhage and necrosis (60%). After observing the gross lesions, the specimens were collected and fixed (with formol 10%) to make the histological slices and H&E stain. The slices were observed, studied under the optical microscope to determine the damage at the cellular level in the different internal organs. As a result,
the histological lesions of the lungs included the congestion and hemorrhage (100%), necrosis foci (75%), infiltration of inflammatory cells (100%). The lesions in the liver showed congested liver parenchyma (87.5%), hemorrhage (50%), necrosis (50%), and inflammatory cell infiltration (100%). The lesions in the stomach, showed the conjunction and hemorrhage, cell necrosis and inflammatory cell infiltration at 50%, 87.5%, 75%, 62.5%, respectively. The common intestinal histological lesions were hemorrhage and necrosis (87.5%), inflammatory cell infiltration (100%).
