Identification and Antibiotic Resistance Profile of Salmonella spp. and Citrobacter spp. Isolated from Street-Vended Beverages

The risk of foodborne diseases as well the dissemination antibiotic resistant bacteria increases with consumption street-vended food and beverages. This study investigated prevalence Salmonella spp. Citrobacter in beverages sold Chow Kit, Kuala Lumpur, Malaysia. Kirby-Bauer disk diffusion method was used to identify resistance profile isolates towards 11 selected antibiotics. Six beverage samples were found positive for presumptive Upon confirmation via Microgen kit PCR biochemical testing methods, only one isolate confirmed be enterica serovar Derby while other identified (n= 12; 2 from each sample). antibiogram test showed that 58.3%, 16.7%, 8.3% strains tested tetracycline, cephalexin, ampicillin respectively, all fully toward penicillin erythromycin. highest MAR index (0.45) S231, five antibiotics (penicillin, erythromycin, ampicillin). Seven had a 0.27 three antibiotics, remaining four lowest (0.18) two shows have high spreading antibiotic-resistant public should considered emerging multidrug-resistant production system.
