Abstract

The study was conducted on 51 uterine biopsy samples collected from 14 normal fertile and 37 repeat breeding cows for bacteriological examinations to find out the prevalence of bacterial flora and their role in repeat breeding syndrome. Presence of bacteria was detected in 23 samples (62.2%) repeat breeding cases in contrast to only 4 (28.6%) bacterial infections from normal fertile cows. About 60% of the microbial isolates were commonly recovered from repeat breeders as well as from normal fertile cows in varying proportions. Of the 37 suffered from repeat breeders, 23 samples (62.2%) yielded 54 bacterial isolates; where Staphylococcus was predominant 14 (37.8%), followed by Bacillus 13 (35.1%), E. coli 11 (29.7%), Pseudomonas 7 (18.9%) while Gram negative minute rod shaped bacteria was 9 (24.3%). The isolates of Pseudomonas and Gram negative minute rod shaped bacteria were obtained only from repeat breeder cows with mucopurulent uterine discharges. There was a positive correlation (r=0.94) between repeat breeders and bacterial infection of uterus. Antibiotic sensitivity in the present study showed that almost all types of bacterial isolates were found moderately and highly sensitive to amoxicillin, oxytetracycline and ciprofloxacin.

Key words: Bacteria, repeat breeding, uterine biopsy, histopathology and antibiotic sensitivity
