Abstract

Objective

Estimate the presence of methicillin resistant Staphylococcus aureus (MRSA), extended beta-lactamase (ESBL) producing Enterobacteriaceae, and vancomycin resistant enterococci (VRE) in bulk tank milk in dairy herds in New South Wales (NSW), Australia.

Methods

Bulk tank milk samples (n = 80) were collected from dairy farms (n = 40, i.e. 2 per farm) in NSW during 2021. Bacteria were cultured using selective chromogenic indicator media with isolate identity confirmed using biochemical testing, Gram stain, and MALDI-TOF mass spectroscopy. Antimicrobial resistance (AMR) was confirmed using antibiotic disk diffusion.

Results

No samples tested positive to the targeted AMR organisms.

Conclusion

The prevalence of MRSA, ESBL-producing Enterobacteriaceae, and VRE is low in NSW dairy herds.

在澳大利亚新南威尔士州的散装罐奶中，抗微生物微生物(耐甲氧西林金黄色葡萄球菌、产生扩展β -内酰胺酶的肠杆菌科和耐万古霉素肠球菌)的流行率较低

目的了解耐甲氧西林金黄色葡萄球菌(MRSA)、产生扩展β -内酰胺酶(ESBL)的肠杆菌科细菌和耐万古霉素肠球菌(VRE)在澳大利亚新南威尔士州奶牛群散装罐乳中的存在情况。方法在2021年从新南威尔士州的奶牛场(n = 40，即每个奶牛场2个)收集散装罐奶样本(n = 80)。细菌采用选择性显色指示剂培养，通过生化试验、革兰氏染色和MALDI-TOF质谱鉴定分离菌株。抗菌药物耐药性(AMR)采用抗生素纸片扩散法确定。结果所有样本均未检出AMR靶菌。结论新南威尔士州奶牛群中MRSA、产esbl肠杆菌科和VRE的患病率较低。
