In this study, an incidence 0.224% (56/25000) of hepatic abscess was recorded. Escherichia coli was isolated in highest number of cases which showed metallic sheen on eosin methylene blue agar in 12 cases (21.48%). Serotype O26 E. coli was identified and recognized as an emerging pathogen. Other pathogens isolated were Streptococcus spp., Fusobacterium necrophorum, Staphylococcus spp., Corynebacteria spp. and Pseudomonas spp. Grossly, single to multiple and minute to large creamy-yellow coloured abscesses of varying sizes were found on both parietal and visceral surfaces of liver. Histologically, the abscesses consisted of central areas of liquefactive necrosis surrounded by numerous polymorphonuclear neutrophils, few mononuclear cells, calcified centers and colonies of bacteria.enSmall ruminantsHepatic abscessE. coli O26Article
