Abstract

The state of contamination by methicillin-resistant Staphylococci, including methicillin-resistant Staphylococcus aureus (MRSA) at the conservative dentistry section of the School of Dentistry, Aichi-Gakuin University, was investigated. Methicillin-resistant coagulase-negative Staphylococci (MRCNS) were detected in 8 (20.5%) of 39 dental staff (28 dentists, 8 dental hygienists, and 3 dental assistants), but MRSA was not detected. MRCNS was also detected in locations such as the dental chair, dental bracket, dental cabinet, and floor, as well as in airborne samples. The presence of the same strain in both the oral cavity of staff persons and the dental chair/floor locations was determined by biochemical properties, antibiotic sensitivity tests, and electrophoretic patterns.

摘要

对爱知学院大学牙科学院保守牙科科室耐甲氧西林葡萄球菌（包括耐甲氧西林金黄色葡萄球菌，即MRSA）的污染状况进行了调查。在39名牙科工作人员（28名牙医、8名口腔卫生员和3名牙科助手）中，有8人（20.5%）检测出耐甲氧西林凝固酶阴性葡萄球菌（MRCNS），但未检测出MRSA。在牙科椅、牙托、牙科橱柜和地面等位置以及空气样本中也检测到了MRCNS。通过生化特性、抗生素敏感性试验和电泳图谱确定了工作人员口腔与牙科椅/地面位置存在相同菌株。
