A new immunoenzymatic assay (IEA) for the identification of Staphylococcus aureus strains of both human and animal origin was compared with rapid commercial kits. The sensitivities and specificities of the commercial kits varied from 90.2 to 96% and 90.8 to 93.7%, respectively. The IEA did not give any false-negative or false-positive results, while commercial kits gave high percentages of false-positive results among clumping factor-positive non-S. aureus strains. The IEA is particularly useful for isolates for which identification is doubtful, for large-scale epidemiological studies, and for identifying isolates from animals as S. aureus.
一种用于鉴定人和动物源金黄色葡萄球菌菌株的新型免疫酶测定法（IEA）与快速商用试剂盒进行了比较。商用试剂盒的灵敏度和特异性分别在90.2%至96%和90.8%至93.7%之间。IEA未产生任何假阴性或假阳性结果，而商用试剂盒在凝聚因子阳性的非金黄色葡萄球菌菌株中产生了较高比例的假阳性结果。IEA对于鉴定存疑的分离株、大规模流行病学研究以及将动物分离株鉴定为金黄色葡萄球菌特别有用。
