Microbial Contaminants in Fresh and Extended Turkey Semen and their Sensitivity to Antibiotics

Microorganisms that inhabit the avian cloaca usually contaminate poultry semen which could easily spread throughout an entire flock. This study was conducted to determine presence of microbial contaminants in turkey and evaluate their antibiotic sensitivity. Semen collected from each tom, pooled then divided into two aliquots A B. Aliquot immediately evaluated for sensitivity while aliquot B, extended preserved 24 hours at 40 C thereafter culture, identification were conducted. Escherichia coli, Enterococcus faecalis, Bacillus subtilis, Corynebacteria species a fungal organism Candida albican isolated identified both aliquots. All organisms sensitive pefloxacin, gentamicin ciprofloxacin, subtilis resistant Ampicillin-cloxacillin, cefuroxime, amoxicillin ceftriaxone. coli only co-trimoxazole, ofloxacin nalidixic acid. The concludes that, foecalis, found be penicillin streptomycin combination extender but ciprofloxacin.
