Abstract :

The purpose of this research was to determine frequency and bacterial agents of hepatic abscesses of cattle slaughtered at Urmia abattoir, Iran.Post-mortem examination of 2179 cattle showed that 36 (1.65%) exhibited liver abscesses. All abscesses were cultured for aerobic and anaerobic bacteria. Isolates were identified as follows: Arcanobacterium pyogenes, Fusobacterium necrophorum, Escherichia coli, Staphylococcus spp., Pseudomonas aeruginosa, Streptococcus spp. and Corynebacterium pseudotuberculosis. This study revealed that A. pyogenes is the most important isolate of liver abscesses (58.33%) and F. necrophorum is the second important isolate of liver abscesses (52.77%) in cattle of Urmia district. In the present study C. pseudotuberculosis is reported for the first time from bovine liver abscesses (5.55%).
