ABSTRACT
Objectives: Ducks are potential carriers of pathogenic bacteria which are capable of transmitting zoonotic diseases to humans as a result of the various interactions with man. Ducks droppings may contaminate the environment with antimicrobial-resistant bacteria. This work was set to identify organisms isolated from duck droppings that may be pathogenic to man.
Methodology and Results: In this study, fecal droppings were obtained from 60 ducks in two rural areas in Badagry. Nigeria. Isolation and identification of enteric bacteria was done by using enrichment media, selective media, and biochemical tests. Antibiotic susceptibility testing by the disk diffusion method was conducted on the enteric bacteria using ofloxacin, amoxicillin, augmentin, tetracycline, cotrimixazole, nitrofurantoin, gentamicin and nalidixic acid.
Conclusions and application of findings: Prevalence of Salmonella spp., Escherichia coli, Klebsiella pneumonia, Citrobacter freundii and Proteus mirabilis were respectively found to be 30%, 8.6%, 13.4%, 9.9% and 38.3%. Organisms were 100% sensitive to ofloxacin; 92.2% resistanT28. to amoxicillin, 88.2% resistant to Augmentin, 98.1% resistant to Tetracycline, 54%resistant to cotrimoxazole, 88.2% resistant to nitrofuratoin while those resistant to gentamicin and nalidixic acid was 17% and 11% respectively. Salmonella sp. had 80% sensitivity to nalidixic acid. The risk posed by the droppings of these birds with organisms like Salmonella spp., and other zoonotic organisms capable of leading to life threatening diarrhea in man is emphasized.
