BACKGROUND
We describe coagulase-negative staphylococci (CoNS) isolates collected from ducklings exhibiting tremor in South Korea over the period of 2010 to 2011. Screening of antimicrobial susceptibility and analysis of SCCmec elements of CoNS were also investigated.
RESULTS
Staphylococcus cohnii was the most frequent staphylococcus (9 isolates) and S. sciuri (4 isolates), S. lentus (3 isolate), S. simulans (1 isolate) and S. epidermidis (1 isolate) were also detected. Among the 15 antimicrobials tested in this study, resistance against oxacillin (15 isolates, 83.3%) was most frequently observed, but only one isolate (SNUDS-1) possessed mecA. This isolate was shown to possess SCCmec type III; the type 3 ccr complex and the class A mec complex.
CONCLUSIONS
Based on these results, isolate SNUDS-1 was shown to possess SCCmec type III; the type 3 ccr complex and the class A mec complex. Although the SCCmec type III is not predominant in human, MR-CoNS (Methicillin resistance Coagulase-negative staphylococci) in food animals should be monitored to prevent the dissemination of antimicrobial resistance genes and resistant pathogens to the community.
背景
我们描述了2010年至2011年期间从韩国出现震颤症状的雏鸭中分离出的凝固酶阴性葡萄球菌（CoNS）。还对CoNS的抗菌药敏性进行了筛选，并对SCCmec元件进行了分析。
结果
科氏葡萄球菌是最常见的葡萄球菌（9株），还检测到松鼠葡萄球菌（4株）、缓慢葡萄球菌（3株）、模仿葡萄球菌（1株）和表皮葡萄球菌（1株）。在本研究测试的15种抗菌药物中，最常观察到对苯唑西林的耐药性（15株，83.3%），但只有一株（SNUDS-1）携带mecA。该菌株显示携带III型SCCmec；3型ccr复合体和A类mec复合体。
结论
基于这些结果，菌株SNUDS-1显示携带III型SCCmec；3型ccr复合体和A类mec复合体。虽然III型SCCmec在人类中并不占主导地位，但应监测食用动物中的耐甲氧西林凝固酶阴性葡萄球菌（MR-CoNS），以防止抗菌耐药基因和耐药病原体传播到社区。
