              Abstract 
 
                The study 
                was conducted on 190 milk samples of bovine mastitis and 138 
                samples were confirmed positives for microorganisms. All the 138 
                samples were subjected to drug sensitivity test. The most 
                effective antibiotic was enrofloxacin (91.67%) 
                followed by ciprofloxacin (90.15%), amikacin (87.12%), 
                ceftriaxone 
                (84.10%),  
                chloramphenicol (80.31%), cefotaxime (79.55%) 
                and gentamicin (77.27%). 
                Microorganisms were mostly resistant to drugs like streptomycin, penicillinG, ampicillin, cloxacillin, amoxycillin and 
                neomycin in increasing order of resistance. Hence, it is 
                suggested that the line of treatment should be based on antibiogram study 
                of various isolates from bovine mastitis. Further, the selection 
                of drugs after culture and sensitivity test should be based on 
                their ability to cross blood tissue barrier or mammary 
                parenchyma, lipophilicity and 
                ability to work in alkaline pH.
