Abstract

A total of 128 semen samples were obtained from buffalo-bulls (3-8 years old) using sterile artificial vagina. The incidence of different microorganisms were : E.. coil (16.8%), Pseudomonas aeruginosa (15.2%), Strept.faecalis (11.6%) ,Staph. epidermidis (10.4%), Staph. aureus (9.6%), Coryne. renale (8.4%), Proteus vulgaris (7.6%) Stept. pyogenes (72%) and Coryne.pyogenes (6.8%). The total bacterial count of buffalo neat semen samples ranged from 3.1 to 5.7 x 106 bacteria /ml. Sensitivity tests of bacterial isolates revealed that Gentamycin, Cephapirin, Amikacin and Doxycycline had more prominent effects than Penicillin and Streptomycin
