Abstract

A total of 137 strains of Staphylococcus species were blindly tested by four rapid serological assays, and the results were compared with those of the tube coagulase assay. For the S. aureus isolates, the Sero-STAT Staph assay gave six false-negative results, four of which were for methicillin-resistant strains. The Accu -Staph, Staphylatex , and Staphyloslide assays identified all the coagulase-positive strains as Staphylococcus aureus. Among the coagulase-negative staphylococci, false-positive results were seen with strains of S. capitis. S. saprophyticus, and S. cohnii. The overall accuracy of the kits compared with the tube coagulase test ranged from 95.1 to 100%.

摘要

采用四种快速血清学检测方法对总共137株葡萄球菌属菌株进行盲测,并将结果与试管凝固酶检测结果进行比较。对于金黄色葡萄球菌分离株,Sero-STAT葡萄球菌检测出现了6例假阴性结果,其中4例是耐甲氧西林菌株。Accu-Staph、Staphylatex和Staphyloslide检测将所有凝固酶阳性菌株鉴定为金黄色葡萄球菌。在凝固酶阴性葡萄球菌中,头状葡萄球菌、腐生葡萄球菌和科氏葡萄球菌菌株出现了假阳性结果。与试管凝固酶试验相比,这些试剂盒的总体准确率在95.1%至100%之间。
