本研究的目的是检查葡萄球菌属的发生。在希腊地区屠宰场屠宰猪的扁桃体中，葡萄球菌属的抗生素耐药性。分离株，以及金黄色葡萄球菌分离株的产肠毒性。葡萄球菌属在总共 144 个扁桃体样本中的 70 个 (48·61%) 中分离出。凝固酶阳性葡萄球菌 (CoPS) 中的优势种是金黄色葡萄球菌，而凝固酶阴性葡萄球菌 (CoNS) 中的优势种是表皮葡萄球菌和腐生葡萄球菌。葡萄球菌属分离株对四环素（97·1%）或克林霉素（80·0%）的抗生素耐药率高，对夫西地酸（14·3%）的抗生素耐药率低。未鉴定出耐甲氧西林金黄色葡萄球菌 (MRSA) 菌株，和所有葡萄球菌属。分离株对万古霉素敏感。在 26 株金黄色葡萄球菌中，21 株 (80·76%) 具有葡萄球菌肠毒素基因，具有七种不同的肠毒素基因谱。主要的肠毒素谱是 seg、sei 和 sej，有七个金黄色葡萄球菌分离株。耐多药葡萄球菌的发生。猪扁桃体中的细菌表明猪肉消费者和处理者在产生抗微生物药物耐药性时会面临公共卫生风险。

Occurrence, antibiotic resistance, and enteroxigenicity of Staphylococcus spp. in tonsils of slaughtered pigs in Greece

The aims of the present study were to examine the occurrence of Staphylococcus spp. in the tonsils of slaughtered pigs in a regional slaughterhouse in Greece, the antibiotic resistance of the Staphylococcus spp. isolates, and the enteroxigenicity of the S. aureus isolates. Staphylococcus spp. were isolated in 70 (48·61%) out of the total 144 tonsil samples. The predominant species was S. aureus in coagulase‐positive staphylococci (CoPS), while the predominant species were Staphylococcus epidermidis and Staphylococcus saprophyticus in the coagulase‐negative staphylococci (CoNS). Staphylococcus spp. isolates presented high antibiotic resistance frequencies to tetracycline (97·1%) or clindamycin (80·0%) and low antibiotic resistance frequencies to fusidic acid (14·3%). No methicillin‐resistant S. aureus (MRSA) strains were identified, and all Staphylococcus spp. isolates were susceptible to vancomycin. Among the 26 S. aureus isolates, 21 (80·76%) possessed staphylococcal enterotoxin genes with seven different enterotoxin gene profiles. The predominant enterotoxin profile was seg, sei and sej with seven S. aureus isolates. The occurrence of multidrug resistant Staphylococcus spp. in pig tonsils indicate public health risk to pork consumers and handlers in developing antimicrobial resistance.
