Abstract: Bovine mastitis is one of the most prevalent diseases in the cow industry with severe economical loss. To understand the etiology of bovine mastitis and provide references for controlling bovine mastitis in Tianjin, in this study, the suspected milk samples of bovine mastitis from four cow farms in this region were analyzed by pathogen isolation, morphology observation, biochemical tests and drug sensitivity tests. The results show that Staphylococcus aureus and E coli. were the main isolates and they were sensitive to ciprofloxacin, ceftazidime, levofloxacin, cotrimoxazole, gentamicin, kanamycin, tetracycline and neomycin, with various degrees of resistance to other antibiotics. The study demonstrated the main pathogens and sensitive drugs for bovine mastitis in part regions of Tianjin, and provided guiding significance for prevention and control of the disease.

Key words: bovine mastitis, pathogenic bacterium, isolation and identification, drug sensitivity test
