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.

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