This article reports the development of a novel fluorometric indicator which shows a rapid response when exposed to coagulase positive Staphylococcus aureus (SA) bacteria (including methicillin sensitive Staphylococcus aureus (MSSA) and methicillin resistant Staphylococcus aureus (MRSA) bacteria). The test is robust and will detect a wide variety of SA strains and there is no significant fluorescence response observed for other species of bacteria commonly found in clinical specimens, including other Staphylococcus bacteria. This research forms the basis of a prototype SA testing kit for the rapid detection of SA within hospital and healthcare environments as an economical prescreen or alternative to the current PCR based testing methodology. Rapid identification of SA carriers will allow hospital infection control teams to be pre-emptive and could significantly reduce the incidence of hospital acquired infections involving this organism.
本文报道了一种新型荧光指示剂的开发,该指示剂在暴露于凝固酶阳性金黄色葡萄球菌 (SA) 细菌(包括甲氧西林敏感金黄色葡萄球菌 (MSSA) 和甲氧西林耐药金黄色葡萄球菌 (MRSA) 细菌)时显示出快速响应。该测试非常稳健,可以检测多种 SA 菌株,并且对于临床标本中常见的其他细菌(包括其他葡萄球菌)没有观察到明显的荧光反应。这项研究构成了 SA 测试套件原型的基础,用于在医院和医疗保健环境中快速检测 SA,作为经济的预筛选或当前基于 PCR 的测试方法的替代方案。快速识别 SA 携带者将使医院感染控制团队能够先发制人,并可以显着降低涉及该生物体的医院获得性感染的发生率。
