For this purpose two upazilla were selected under the Nilphamari district. On the basis of morphology, staining, cultural and biochemical characteristics, the isolated organisms were classified as<em>, Staphylococcus </em>spp., <em>Streptococcus </em>spp., <em>E. coli, and Bacillus </em>spp. .For this study, a total of 48 samples were collected from affected mastitis cows. Out of 48 milk samples, 17 were positive for <em>Staphylococcus </em>spp. (35.42%), 9 were positive for <em>Streptococcus </em>spp. (18.75%), 7 were positive for <em>E. coli </em>(14.58%), 5 were positive for <em>Bacillus </em>spp.(10.41%),5 were positive for mixed organisms (10.41%) and 5 were unidentified organisms (10.41%). Antibiogram studies revealed that all of the isolates of <em>Staphylococcus </em>spp. were sensitive to gentamicin and were resistant to streptomycin. Gentamicin was sensitive to all of the isolates of <em>Streptococcus </em>spp. and was resistant to streptomycin. The isolates of <em>Bacillus </em>spp. were sensitive to ciprofloxacin and <em>Bacillus </em>spp. was resistant to streptomycin. All of the isolates of <em>E. coli </em>were sensitive to ciprofloxacin the isolates were resistant to ampicillin and amoxicillin. Over all sensitivity revealed that ciprofloxacin, gentamicin and enrofloxacin were most efficacious. Thus, it may be recommended that ciprofloxacin, gentamicin and enrofloxacin in optimum doses would resolve most cases of clinical mastitis in dairy cows.</p><p>Asian J. Med. Biol. Res.
