Bacteriologic studies of liver abscesses of Awassi sheep in Jordan

A total of 337 liver abscesses of Awassi sheep that were found in different slaughterhouses in Jordan were examined for their causal agents. Fifteen different bacterial species were isolated from 297 liver abscesses. No bacteria were isolated from the remaining 40 liver abscesses. Fusobacterium necrophorum biovar B were isolated from 195 (58%) abscesses. Arcanobacterium pyogenes, F. necrophorum biovar A, Escherichia coli and Clostridium perfringens were isolated from 41 (12%), 34 (10%), 30 (9%) and 17 (5%), respectively, liver abscesses. Our study suggested that F. necrophorum biovar B is the most prevalent bacterium incriminated for liver abscesses in Awassi sheep. © 2002 Elsevier Science B.V. All rights reserved.
