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%) andStreptococcus spp. (6%) Additionally, twelve cases were caused by nonbacterial agents. The bacteria isolates were tested for theirin-vitrosusceptibility 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%).
