Quantification of Methicillin-Resistant Staphylococcus aureus Strains in Marine and Freshwater Samples by the Most-Probable-Number Method

摘要

Recreational beach environments have been recently identified as a potential reservoir for methicillin-resistant Staphylococcus aureus (MRSA); however, accurate quantification methods are needed for the development of risk assessments. This novel most-probable-number approach for MRSA quantification offers improved sensitivity and specificity by combining broth enrichment with MRSA-specific chromogenic agar.
