Abstract
Staphylococcus aureus (SA) is one of the most common pathogenic bacteria, and methicillin-resistant SA (MRSA) is an equally common drug-resistant bacteria. MRSA detection is of great significance for clinical diagnosis, medication guidance, and prevention of antibiotic abuse. Traditional MRSA detection using the culture method is time-consuming, laborious, and difficult to conduct rapid on-site detection. In this research, we developed a device for rapid MRSA detection, which can detect the nuc gene in SA and mecA gene in MRSA simultaneously for 30–40 min. After simple sample processing, the mixture can be directly loaded onto the chip device. The detection results can be directly determined by a color change, with a limitation of approximately 102 copies. This isothermal amplification chip device can be widely applied in many fields, with simple operation and low contamination.
