Antibiogram profiling and pathogenic status of Aeromonas species recovered from Chicken

Abstract

Poultry meat and its products are widely consumed by humans globally, however, Aeromonas infections in poultry have been reported in different parts of the world with devastating effects. This study was carried out to assess the antibiogram and biofilm forming potential of Aeromonas isolated from chicken fecal samples. Aeromonas isolates were screened for antibiotic susceptibility using antibiotics disk and biofilm producing potentials on abiotic surfaces. Nineteen isolates recovered from chicken feces were 100% sensitive to ciprofloxacin, gentamicin and the tetracyclines. About 53% of Aeromonas isolates were resistant to erythromycin and 47% resistant to streptomycin. Eight isolates (42.1%) were found to be moderate producers of biofilm, 31.6% (6/19) were weak producers of biofilm, 10.5% (2/19) were non biofilm producers while 15.8% (3/19) were strong producers. The present investigation shows a prevalence of potentially pathogenic Aeromonas strains in chicken feces, suggesting potential group at risk for Aeromonas infection which could be dissemination to other animals or humans with close contact and the wider community.
