SỰ ĐỀ KHÁNG KHÁNG SINH CỦA STAPHYLOCOCCUS AUREUS TRONG MỘT SỐ MẪU THỨC ĂN ĐƯỜNG PHỐ
Tóm tắt
S. aureus là nguyên nhân hàng đầu gây ngộ độc thực phẩm, đặc biệt là ở các thực phẩm đường phố. Trong nghiên cứu này, tổng cộng 9 mẫu thức ăn đường phố được khảo sát sự hiện diện của S. aureus bằng phương pháp định lượng trên môi trường thạch Baird-Parker và thử khả năng sinh enzyme coagulase. Kết quả cho thấy có 1/9 mẫu nhiễm S. aureus, chiếm tỉ lệ 11,1%. Tổng số 37 chủng S. aureus được khảo sát sự đề kháng đối với các kháng sinh cefoxitin, kết quả cho thấy 59,5% các chủng là chủng đề kháng methicillin MRSA.
