Isolation and Antimicrobial Susceptibility of Bacteria Causing Mastitis from Dairy Cows in Omdurman locality-Sudan
The present study was designed to investigate the sensitivity of tylosin and enrofloxacin against bacteria isolated from mastitic milk collected from Omdurman dairy farms. out of one hundred isolates from mastitic cow milk 70% were Gram +ve, and 30% were Gram -ve bacteria. Among the total of Gram +ve isolates, bacterial examinationshowed57.1%Staphylococcus spp., 25.7% Bacillus spp, 8.6% Streptococcus spp., 5.7% Corynebacterium spp. and 2.9%Actinomyces spp. while Gram –ve bacteria were found to be 86.7% Enterobacter spp., and 4 13.3% E. coli. Antibiotic susceptibility tests to Tylosin and Enroflaxcin were performed for the isolated bacteria: Staphylococcus aureus, Staphylococcus epidermidis, Enterobacter aerogenes, Enterobacter faecalis were found to be highly sensitive to tylosin and enrofloxacin.
