Abstract :

In the present study, an attempt has been made to isolate, identify the bacterial species from infected bovine udder tissues and the histopathological assessment of mild, acute, chronic and fatal stages. The collected mammary tissue samples were subjected to microbiological and histopathological examination. Staphylococcus spp, E.coli, Streptococcus spp, S. dysagalactiae S. agalactiae, Bacillus spp, Proteus spp, Serrate spp, S. pneuminiae, S.uberis, S. subtilus, Klebsiella spp, Corrymbacteria and Mycoplasm bacterial species were identified. Staphylococcus spp showed highest occurrence (39.16%) followed by E.coli (31.66%), Streptococcus spp (12.5%) and followed by other species. Histological examination demonstrated considerable reduction in alveolar epithelial and luminal areas and increase in connective tissue stroma and leukocytes, illustrating limited development and shows inflammation of infected tissue. The prevalence of these contagious and natural bacterial species in the present study is probably due to the poor hygienic condition in the herds. The present study provides baseline information on bovine mastitis in this region.
