The aim of this study was to identify the preputial aerobic bacterial flora from bulls, rams and bucks and to determine their antimicrobial sensitivities. Preputial swabs were collected randomly from twenty each of clinically healthy post pubertal bulls, rams and bucks. Using standard bacteriological techniques, the following bacteria were identified; Escherichia coli (bulls 26.5%, rams 19.2% and buck 22.7%), Staphylococcus aureus (bulls 25.0 %, rams 26.0 % and bucks 24.2 %), Streptococcus (bulls 20.6%, rams 26.0 % and bucks 25.8%), Salmonella (bulls 14.7%), Shigella (rams 15.1% and bucks 15.2%) and Klebsiella (bulls 13.2%, rams 13.7 % and bucks 12.1%) species. There was no statistically significant difference (p>0.05) between the proportions of bacterial species and different animal species. In bulls, all bacterial isolates were susceptible to Ciprofloxacin (100%) and Levofloxacin (100%) while 60% of the bacterial isolates showed resistance to amoxicillin, ampiclox and streptomycin. In rams, all the bacterial isolates were susceptible to ciprofloxacin (100%) and gentamycin (100%) while 40% of bacterial isolates were resistant to chloramphenicol. In bucks, all bacterial isolates were susceptible to amoxicillin (100%), ampiclox (100%) and gentamycin (100%) while 20% bacterial isolates were resistant to streptomycin. This study shows that a few bacteria colonize the prepuce of ruminants in Maiduguri and there is need for preputial washing prior to breeding to reduce contamination of semen during natural mating or collection. Amoxiciillin, ampiclox, ciprofloxacin and gentamycin could be used as therapeutic agents to diseases that could be caused by the bacteria in prepuce of these animal species.
