Staphylococcus aureus is an important pathogen of foodborne origin. The pathogen produces a variety of toxins that include the staphylococcal enterotoxins (SE). The present study aimed to evaluate the prevalence and expression of 5 SE genes (sea, seb, sec, sed, and see) in S. aureus isolated from outbreaks occurred in the state of Rio Grande do Sul, Brazil. All isolates, with the exception of 2, presented the same or higher transcriptional expression than the reference strains for at least 1 of these genes. The presence of SE genes combined with high levels of transcriptional expression suggests that 1 or more SEs were involved with the staphylococcal food poisoning outbreak analyzed in the present study.
金黄色葡萄球菌是一种重要的食源性病原体。该病原体产生多种毒素，包括葡萄球菌肠毒素（SE）。本研究旨在评估从巴西南里奥格兰德州发生的疫情中分离出的金黄色葡萄球菌中5种SE基因（sea、seb、sec、sed和see）的流行情况和表达情况。除2株外，所有分离株至少有1个基因的转录表达与参考菌株相同或更高。SE基因的存在与高水平的转录表达表明，在本研究分析的葡萄球菌食物中毒疫情中，有1种或更多种SE参与其中。
