TI  - Pathogenic Bacteria Present in the Lochia First 10−Day Postpartum Prolongs Days Open in Dairy Cows
AB  - The aims of this study were to evaluate the antibiotic resistance profiles and virulence genes of bacteria (Escherichia coli, Trueperella pyogenes, Prevotella melaninogenica, and Fusobacterium necrophorum) isolated from lochia during early postpartum and their effects on days open. The study was conducted on isolates, which were obtained from uterine discharges in the first 10 days of postpartum period, from 36 multiparous Simmental cows. The virulence genes of the isolates were investigated by polymerase chain reaction. The antimicrobial susceptibilities of the isolates were examined by the disc diffusion method. T. pyogenes (n = 97) and E. coli (n = 47) were revealed to carry the virulence gene (name of the gene), but not F. necrophorum (n = 16) and P. melaninogenica (n = 15). All isolates tested in this study were significantly sensitive to beta−lactam and tetracycline. E. coli and T. pyogenes were susceptible to aminoglycoside antibiotics, while F. necrophorum and P. melaninogenica were resistant to them. E. coli and F. necrophorum were susceptible to trimethoprim−sulfamethoxazole while T. pyogenes and P. melaninogenica were resistant. Those bacteria were predominant in cows with a prolonged days open (P<0.05). The uterine bacteria are responsible for prolonged days open and beta−lactam−derived antibiotics could be used as the first choice in the treatment of fresh cow uterine infections.
