Abstract:
A total of 50 cases of bovine clinical mastitis in Tripoli were subjected to microbiological examination. Thirty-five bacterial isolates were obtained and further identified by using the biochemical tests. Staphylococcus spp. (36%) was the predominant causative organism, then E. coli (24%) and Streptococcus spp. (6%) Additionally, twelve cases were caused by nonbacterial agents. The bacteria isolates were tested for their in-vitro susceptibility to different antimicrobial agents that are used in commercial intramammary infusion products. Antibacterial susceptibility testing showed that the bacteria isolates were sensitive to ciprofloxacin (100%), enrofloxacin (96%), cefotaxime (90%), deoxicillin (88.8%), clorophenicol (66.5), ampicillin (62.5%), amoxicillin (50%), vancomycin (42%) and fusidic acid (33.3%).
According to these results, the ciprofloxacin was proved to be the drug of choice.
