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.
