Correlation of Oxacillin MIC with mecA Gene Carriage in Coagulase-Negative Staphylococci [PDF]

Journal of Clinical Microbiology, 2000
ABSTRACT The National Committee for Clinical Laboratory Standards has recently changed the oxacillin breakpoint from ≥4 mg/liter to ≥0.5 mg/liter to detect methicillin-resistant coagulase-negative staphylococci (CoNS) because the previous breakpoint lacked sensitivity.

One Health Genomic Analysis of Methicillin‐Resistant Staphylococcus spp. From Humans, Cats, and Dogs in a Veterinary Hospital in Central Chile

Zoonoses and Public Health, EarlyView.
ABSTRACT Introduction The emergence of methicillin‐resistant Staphylococcus species (MRS) poses a growing threat to both human and veterinary health. Methods We performed a comparative genomic characterisation of 49 methicillin‐resistant Staphylococcus isolates collected from humans, dogs, and cats in a veterinary hospital from Central Chile.

Absence of the mecC gene in methicillin-resistant Staphylococcus aureus isolated from various clinical samples: The first multi-centered study in Turkey

Journal of Infection and Public Health, 2019
Background: mecA is a predefined gene causing methicillin resistance in Staphylococcus aureus (S. aureus) isolates; however, it has been shown that some methicillin-resistant S. aureus (MRSA) strains do not carry this gene. Recently, in isolates found to

Multiplex real-time PCR for detection of Staphylococcus aureus, mecA and Panton-Valentine Leukocidin (PVL) genes from selective enrichments from animals and retail meat. [PDF]

PLoS ONE, 2014
The aim of this study was to compare a real-time PCR assay, with a conventional culture/PCR method, to detect S. aureus, mecA and Panton-Valentine Leukocidin (PVL) genes in animals and retail meat, using a two-step selective enrichment protocol.

Characterizing Scales of Genetic Recombination and Antibiotic Resistance in Pathogenic Bacteria Using Topological Data Analysis

, 2014
Pathogenic bacteria present a large disease burden on human health. Control of these pathogens is hampered by rampant lateral gene transfer, whereby pathogenic strains may acquire genes conferring resistance to common antibiotics. Here we introduce tools

Loss of themecAGene during Storage of Methicillin-ResistantStaphylococcus aureusStrains [PDF]

Journal of Clinical Microbiology, 2005
ABSTRACTThemecAgene was lost in 36 (14.4%) of 250 methicillin-resistantStaphylococcus aureusisolates after 2 years of storage at −80°C with the Microbank system (Pro-lab Diagnostics, Austin, Tex.). Further analysis of 35 of these isolates confirmed loss of themecAgene in 32 isolates.

A Pilot Metagenomic Study Demonstrating Virtual Reality Head Mounted Displays Utilized in Medical Education Are Reservoirs of Viable Pathogenic Microbes

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Metagenomic analysis identified 27 pathogenic bacteria including 4 "ESKAPE" pathogens (Enterobacter sp., Staphylococcus aureus, Klebsiella spp., and Escherichia coli) and numerous organisms associated with ocular infections. A broad range of antimicrobial resistance genes were identified conveying resistance to Methicillin, Aminoglycosides, Macrolides,

Evaluation of the accuracy of various phenotypic tests to detect oxacillin resistance in coagulase-negative staphylococci

Brazilian Journal of Infectious Diseases
In this study, we determined the accuracy of phenotypic tests (cefoxitin agar dilution, 30µg-cefoxitin and 1µg-oxacillin disks) to detect the oxacillin resistance/mecA gene among coagulase-negative staphylococci (CoNS) isolates.
