Study the Histopathological Changes and Bacteriological Causes of Natural Infection of the Livers in Sheep at Diyala Province

Abstract

His study was conducted to explore bacterial infection, in addition to pathological (grossly and microscopically ) changes in liver of sheep in Diyala province, samples( blood and livers tissue) of 200 sheep were taken from butchers and slaughtered house at Diyala province. Blood sample were collected by jugular veins using sterile plain tubes, labeled according to the neck tag of animals and taken to laboratory (Ministry Science and Technology and General Baquba Hospital), Hematological study which involve Hb and PCV parameters were done, while Serum was separated from coagulated blood sample by centrifugation for measuring some parameters assay related to liver enzyme which include: ALT, AST, Total bilirubin and total protein. The results of current study revealed the bacterial infection which are Staphylococcus(15%), E.coli (15%), Streptococcus (12%), Proteus (7%) ,and Pseudomonas (6%) ), It was manifested by liver abscess , hemorrhagic, necrosis and inflammation. AST enzyme decreased in the E.coli (221+5.81 ),while increase in Staphylococcus (205+7.80), while ALT enzyme decreased in E.coli (48.03+5.89), The total bilirubin which are increased in Staphylococcus (1.3 + 0.23), while the total bilirubin which are decreased in E.coli (1.3±0.23).
