OCCURRENCE AND ANTIBIOTIC SENSITIVITY PROFILING OF Staphylococcus aureus ISOLATED FROM RAW CHEVON

Abstract

The chevon is an animal source protein that is delicious, nutritious and a very well-known food for all. This study aimed to determine the prevalence as well as the antibiotic sensitivity of Staphylococcus aureus in chevon sold at the different wet markets in Dhaka City. A total of 120 samples of raw chevon were

4* collected from some selected areas. The cultural characteristics, staining and biochemical properties were used to isolate and identify the S. aureus bacteria. The highest and lowest Total Viable Count (TVC) in the supplied sample were log 10 9.22 CFU/gm and log 9.04 CFU/gm, respectively. The overall prevalence of S. aureus in Dhaka City was 47.5%. The highest prevalence was recorded at BNP Bazar (65%) of the Dhaka City. Isolates were investigated for antibiotic sensitivity profile using a Kirby-Bauer disc diffusion assay against five common antibiotics used in goats. The S. aureus showed the highest sensitivity to gentamicin (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%). These bacterial contaminations in the chevon may be mitigated following proper hygienic management, proper boiling or cooking, and public health awareness.
