OCCURRENCE AND ANTIBIOTIC SENSITIVITY PROFILING OF STAPHYLOCOCCUS AUREUS ISOLATED FROM RAW CHEVON

Abstract

This study aimed to determine the prevalence as well as the antibiotic sensitivity of Staphylococcus aureus in market meat (chevon) sold at the different wet markets in Dhaka city. A total of 120 samples of raw chevon were collected from the selected area. S. aureus was isolated from the samples using standard microbiological methods with their Total Viable Count (TVC). The highest TVC found on a sample was log 10 9.22 CFU/gm and the lowest TVC was log 10 9.04 CFU/gm. Cultural characteristics, biochemical testing, and gram staining were used to isolate and identify bacteria. Prevalence rate of S. aureus ware 47.5%. Isolates were investigated for antibiotic sensitivity profiling by using a Kirby-Bauer disc diffusion assay against five commonly used antibiotics used in goats. S. aureus showed the highest sensitivity to gentamycin (57.9%), followed by ciprofloxacin (56.14%), and the highest resistance pattern was shown against amoxicillin (100%), followed by ampicillin (92.98%), and tetracycline (63.15%). According to the findings of this study, chevon contains multidrug-resistant S. aureus pathogens on market meat. The presence of multidrug-resistant S. aureus bacteria in market meat raises serious public health concerns, which can be transmitted to humans through direct contact or the food chain, posing a public health risk.
