Pathological Assessment of Bovine Liver Abscesses in Basrah Abattoir, Iraq

his study was conducted to examine bovine liver abscesses to identify the pathological aspects of the liver of slaughtered cattle at Basrah Abattoir. Seventy liver samples were collected; sixty samples affected with bovine liver abscesses BLA, and ten healthy liver samples served as control. The hematological results showed a significant (P≤0.05) increase in total WBCs count, lymphocytes count and neutrophil count of BLA when compared to a healthy. Moreover, the results of the biochemical analysis showed a significant (P≤0.05) increase of AST, ALT, ALP, and LDH in BLA compared to healthy. The macroscopically study of the liver of BLA showed multiple nodules vary in size which dispersed on the diaphragmatic and visceral surfaces, which showed friable areas and multiple grayish-white abscesses that containing whitish cheesy materials. The histopathological, revealed dilation of the center vein, pericentral inflammatory cells infiltration mainly polymorphic inflammatory cell, besides, marked area of degenerative changes of hepatocyte particular in the pericentral region as well to multiples abscesses areas were found in the hepatic parenchyma particularly in the subscapular region represented by focal infiltration of neutrophils, The portal vein showed dilated cystic like projection and filled with infiltration of inflammatory cells as well to inflammatory exudate; also, there is the infiltration of inflammatory cells around of portal vein and an early degree of a fibrotic capsule, the current study concluded that the infected bovine with liver abscess can cause much harm, affection in either health status and economic, by effecting the hematological and biochemical balance as well to the inflammatory changes related to this disease.
