ABSTRACT: The research was carried out to study the prevalence of liver infections of cattle in Gazipur district and to investigate the gross and microscopic lesions of the liver infections along with isolation and identification of non-specific bacteria causing infections of cattle. A total of thirty liver samples were collected from different slaughter houses of Gazipur district immediately after slaughter. Nutrient broth was used for taking the swab samples. Different microbiological protocols were used to isolate and identify the bacteria. Four bacterial species were isolated from the collected samples e.g. Staphylococcus aureus, Staphylococcus epididermis, Escherichia coli and Klebsiella pneumoniae subsp. pneumonia. The highest cultural prevalence was found in case of Staphylococcus aureus and Escherichia coli mixed infection (90%). Most frequent cases were abscess with hemorrhages. Multiple firm white nodular lesions with abscess, areas of congestion, necrotic patch were also found in this investigation. In Staphylococcus aureus infections, caseous necrosis surrounded with many neutrophils and fibrous connective tissue proliferation were seen. Leucocytic infiltration in presence of fatty change was found in case of Escherichia coli mixed with other anaerobes bacterial infections. The observed highest lesions were hemorrhages (83.34%) followed by abscess (76.67%), congestion (66.67%) and nodular lesions (60%). Therefore, the study might help to take preventive measures for the reduction of liver infections in cattle in the study area.
