Prevalence of Nasal Colonization of CA-MRSA in Healthy Individuals and Its Antimicrobial Susceptibility Pattern
Background and purpose: Staphylococcus aureus, as a human pathogen, can produce a wide range of infections and its treatment has become a challenge due to increased resistance to antibiotics. The aim of this study was to determine the prevalence of methicillin-resistant (CA-MRSA) type and its antimicrobial susceptibility. Materials and methods: This descriptive cross-sectional study was done i...
متن کاملPerformance of the BD GeneOhm methicillin-resistant Staphylococcus aureus (MRSA) PCR assay for detecting MRSA nasal colonization in Taiwanese adults.
BACKGROUND/PURPOSE A rapid diagnostic method for methicillin-resistant Staphylococcus aureus (MRSA) has been implemented for surveillance of the at-risk population, but its performance in those without traditional risk factors is not clear. The objective of this study was to evaluate MRSA colonization status by comparing the performance of the BD GeneOhm MRSA polymerase chain reaction (PCR) ass...
متن کاملComparison of the Xpert methicillin-resistant Staphylococcus aureus (MRSA) assay, BD GeneOhm MRSA assay, and culture for detection of nasal and cutaneous groin colonization by MRSA.
Detection of methicillin (meticillin)-resistant Staphylococcus aureus colonization was assessed using combined nose and groin swabs in two commercial PCR assays (the Xpert MRSA assay and the BD GeneOhm MRSA assay). Compared to routine culture, both had similar sensitivities (87.0% versus 84.8%, respectively) and specificities (93.8% versus 92.7%, respectively). Combined PCR assays provide a rap...
متن کاملCepheid Xpert MRSA cycle threshold in discordant colonization results and as a quantitative measure of nasal colonization burden.
We analyzed the cycle threshold (C(T)) of PCR surveillance MRSA swabs obtained from veterans. Lower C(T) on admission was associated with a positive culture from nasal swabs at discharge. Compared to PCR, direct plating of nasal swabs performed poorly, especially for patients with an elevated C(T). The C(T) is strongly correlated with quantitative nasal cultures. Clinical and infection control ...
متن کاملAn Ex Vivo Porcine Nasal Mucosa Explants Model to Study MRSA Colonization
Staphylococcus aureus is an opportunistic pathogen able to colonize the upper respiratory tract and skin surfaces in mammals. Methicillin-resistant S. aureus ST398 is prevalent in pigs in Europe and North America. However, the mechanism of successful pig colonization by MRSA ST398 is poorly understood. To study MRSA colonization in pigs, an ex vivo model consisting of porcine nasal mucosa expla...
