ABSTRACT
The antibiogram of organisms of public health importance from vegetable wash water was investigated. Twenty five (25) samples of vegetable wash water from five markets in Umuahia were analyzed. Four bacteria genera: Staphylococcus aureus, E.coli, Shigella spp, salmonella spp were isolated. Staphylococcus areus gave the highest percentage occurrence of 90% while Salmonella spp gave the least percentage occurrence of 30%. The Kirby Bauer disk diffusion method was used for the antibiotic susceptibility test. Staphylococcus aureus was highly susceptible to Ciprofloxacin, Rifampicin and Amoxil while others exhibited least susceptibility. Among the Gram negative organisms E.coli, Shigella spp and salmonella spp were found to be highly susceptible to Ofloxacin, Gentamycin, Augumetin while other species of E.coli, Shigella and Salmonella gave the least susceptibility to Nalidixic acid, Penicillin, Amoxil, Streptomycin, Ciprofloxacin, Levofloxacin and Erythromycin. The Multiple Antibiotic Resistance Index of the organisms ranged between 0.2-0.7. The result of this study showed that vegetable can be an avenue for transferring antibiotic resistant genes in community setting. Hence it is necessary to monitor and understand the critical points in the control of antibiotic resistance among the developing countries.
