Abstract

Drug resistance and biofilm formation among foodborne pathogens has become a serious cause for concern and ready to eat foods have been identified as a source of such foodborne pathogens. Klebsiella spp., a recognized food borne pathogen is emerging as a pathogen that has the capacity to develop multi-drug antibiotic resistance and produce biofilms. Ready to eat Rhynochophorus phoenicis (edible worm) and Archachatina marginata (snail) sold along the Benin/Warri road in southern Nigeria were investigated for the presence of Klebsiella spp., antibiotic resistance pattern of the isolates and the ability of the isolates to produce biofilms. The result of the investigation shows that over 95% of the samples had Klebsiella spp. isolated from them with edible worm samples recording 100% prevalence rate. Result of the antibiotic resistance pattern of the Klebsiella spp. isolates from the various sources shows that over 75% of the isolates were resistant to cefuroxime, amoxicillin, ampicillin, doxycycline and cloxacillin, with all the isolates from edible worm recording 100% resistance to ampicillin. All the isolates irrespective of the source were however susceptible to gentamycin, ofloxacin and ciprofloxacin. Biofilm formation capability result indicate that almost all the isolates were strong biofilm producers irrespective of the surface.  The investigation reveal that surfaces differ in their affinity for biofilm formation by microorganisms as the result shows that plastic are better surfaces for biofilm production by the isolates than aluminum surfaces. The findings from this study gives an indication that indiscriminate eating of road side hawked foods could pose serious health challenge as it clearly confirm not only the presence of proven pathogenic foodborne organisms but also the potentials for spreading antibiotic resistanance among humans.
