ABSTRACT

We evaluated three rapid methods to detect methicillin-resistant Staphylococcus aureus (MRSA) and compared them with PCR amplification of mecA. A total of 103 S. aureus strains were studied by MRSA-Screen, BBL Crystal, Velogene Genomic and mecA PCR. All the methods detected the 61 MRSA strains having the mecA gene, showing 100% sensitivity and specificity. Despite the correlation between all the rapid methods and PCR, the ease of use and shorter turnaround time of MRSA-Screen were important factors leading to the selection of this method as the routine screening technique for MRSA.

ABSTRACT

Se han evaluado tres métodos rápidos para detectar la presencia de Staphylococcus aureus resistente a la meticilina (SARM) y se han comparado con la amplificación del gen mecA mediante reacción en cadena de la polimerasa (PCR). Se estudiaron un total de 103 cepas de S. aureus mediante MRSA-Screen, BBL Crystal, Velogene Genomics y PCR para mecA. Con todos estos métodos se detectaron 61 cepas de SARM que presentaban el gen mecA, con una sensibilidad y especificidad del 100 por ciento.A pesar de la correlación entre todos los métodos rápidos y la PCR, la facilidad de uso y el poco tiempo que lleva a la realización de MRSA-Screen fueron factores importantes para la selección de este método como técnica sistemática de detección de SARM (AU)
