Bovine mastitis is a potentially fatal mammary gland due to physical trauma or microorganisms infections. It the most widespread, costly disease in dairy farms and great concern for many producers developing countries like Ethiopia. The study was conducted test antimicrobial susceptibility of identified pathogens from mastitic cattle. Out 384 lactating cows examined course period, 116 (30.21%) had mastitis. results bacteriological analysis cultured milk samples shown three major strains pathogenic bacteria namely Staphylococcus aureus, Streptococcus agalactiae Escherichia coli were isolated 81 cows, 48 bacterial isolates (59.26 %) as S. 31 (38.27%) Str. two (2.47%) E. (2.47%). agents used gentamycin, kanamycin, erythromycin, chloramphenicol, streptomycin amoxicillin, penicillin ampicillin. vitro showed some degree resistance varying proportions isolates. Some exhibited even more antibiotics. aureus represented 95.8 % total isolates, found resistant while 93.7% sensitive gentamycin. On other hand, agalactiae, maximum recorded ampicillin (35.5%), sensitivity (83.9%). All ampicillin, all them susceptible gentamycin streptomycin. average antimicrobials tested this 37.5%, 41.9% respectively. In comparison, resistivity 41.4%, 13.3%, 43.8% coli, For susceptibility, drugs active, majority penicillin. This antibiotic development among these may pose problem concern. Hence, use both treatment prevention intra-mammary infections must be based on test.
