We investigated the prevalence and the risk factors of nasal carriage of Staphylococcus aureus carrying Panton-Valentine leukocidin genes [Sa PVL(+)] in pupils.
Two hundred and fifty-seven pupils were screened by nasal swabbing. The detection of 16S rRNA, mecA and luk-PV genes was performed by PCR and the risk factors were assessed with the statistical analysis of a questionnaire.
Thirty-one percent of pupils were colonized, with 16.4% of isolates carrying the luk-PV gene and 8.8% the mecA gene. Children aged 7years or more and living in a boarding school were the factors promoting nasal carriage 60% of children who presented with an abscess in the previous year were carriers of luk-PV gene Sa.
The study revealed a high prevalence of luk-PV gene among methicillin-susceptible strains and a statistically significant correlation between the presence of this gene and presenting with an abscess.
我们调查了携带杀白细胞素基因 [Sa PVL(+)] 的金黄色葡萄球菌在小学生中的流行情况和风险因素。
通过鼻拭子对 257 名小学生进行筛查。通过 PCR 检测 16S rRNA、mecA 和 luk-PV 基因，并通过问卷调查评估风险因素。
31%的小学生定植，16.4%的分离株携带 luk-PV 基因，8.8%的分离株携带 mecA 基因。7 岁及以上且住校的儿童是促进鼻定植的因素，去年有脓肿的儿童中有 60%携带 luk-PV 基因 Sa。
本研究显示了耐甲氧西林金黄色葡萄球菌中 luk-PV 基因的高流行率，以及该基因的存在与脓肿的发生之间存在统计学显著相关性。
