Antibiogram status of Commensal Strains involved in Multidrug Resistance recovered from famous street foods of Karachi: A threat for public health.

Abstract

Background: Antimicrobial resistance is, as of now, the quintessential issue these days and commensal microorganisms are contributing their part efficiently in disseminating resistance. Thus, this investigation aimed to determine the antibiogram pattern of bacteria recovered from street vended foods in Karachi city.

Methodology: Kirby Bauer's disc diffusion technique was done to check the sensitivity pattern of foodborne bacteria towards 11 standard antibiotics with a range of (11 - 40 mm) inhibition zone. 

Results:  Nearly all the tested food isolates showed resistance towards oxacillin and amoxicillin. Strains of S. faecalis demonstrated 100 % resistance against gentamicin, chloramphenicol, oxacillin, tobramycin, and streptomycin. Ready-to-eat food contaminated with a high bacterial count is an important matter of concern.

Conclusion: Commensal bacteria are responsible for several foodborne sicknesses and are involved in the mechanism of lateral gene transfer. Hence, the exploitation of drugs and violation of acceptable sanitation standards and good hygiene practices must be restricted to restrain the antimicrobial drug resistance and provide good quality food that fulfills the requirements of consumers' wellbeing.
