Abstract

A study on bovine mastitis due to Corynebacterium spp. showed that out of 2283 quarter milk samples, 224 (9.81%) gave positive reactivity to California mastitis test, while 600 (26.28%) and 1459 (63.9%) recorded as doubtful and negative respectively. Two hundred and five bacterial isolates were recovered from milk samples examined, the isolated bacteria were Staphylococcus spp. 107 (52.5%), Streptococcus spp. 25 (12.3%), Enterobacterium spp. 4 (2%) Lactobacillus spp. 4 (2%), Coryneform bacteria 27 (13.2%). The Coryneform bacteria tested was found to be 100% resistant to penicillin G except Corynebacterium ulcer’s (60%). In contrast Gentamycin was the drug of choice for Coryneform (Resistant=0.0 %).

Key words: Bovine mastitis, Corynbacterum spp., antibiotics, Sudan.
