Abstract
Milk samples from 325 buffaloes, 79 cows and 4 goats suffering from mastitis were studied. The analysis of samples
showed bacterial growth in 353 (86.51%) samples while one
(0.24%) sample showed fungal infection. Of positive samples,
165 (40.44%) revealed mixed infection of Streptococci and Staphylococci, 76 (18.62%) revealed Coliforms, 62(15.19%) Staphylococcus aureus, 25(6.12%) Corynebacterium pyogenese, 12
(2.94%) Str. agalactiae, 7(1.71%) Str. dysgalactiae, 6(1.47%)
Pseudomonas aeruginosa, 1(0.24%)Candida albicans and 54
(12.23%) revealed no growth. The highest number of samples
61.76% were sensitive to gentamicin. Ampicillin gave the lowest results (3.43%) in terms of in vitro sensitivity.
