The anti-repressor MecR2 promotes the proteolysis of the mecA repressor and enables optimal expression of β-lactam resistance in MRSA. [PDF]

PLoS Pathogens, 2012
Methicillin-resistant Staphylococcus aureus (MRSA) is an important human pathogen, which is cross-resistant to virtually all β-lactam antibiotics. MRSA strains are defined by the presence of mecA gene.

Prevalence of mecA, mecC and Panton-Valentine-Leukocidin Genes in Clinical Isolates of Coagulase Positive Staphylococci from Dermatological Canine Patients

Microorganisms, 2022
Coagulase positive Staphylococci (CoPS) are the leading cause of canine cutaneous and otic infections. Virulence factors associated with Staphylococci include the expression of mec and panton-valentine leukocidin (pvl) genes.

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.

In vitro antibiogram pattern of Staphylococcus aureus isolated from wound infection and molecular analysis of mecA gene and restriction sites in methicillin resistant Staphylococcus aureus

Journal of Advanced Pharmaceutical Technology & Research, 2015
Staphylococcus aureus is a common nosocomial pathogen with property to develop resistance to antimicrobial agents. But in the modern era, drug resistance had been developed by microbes due to its continuous usage of antibiotics.

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.

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.

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,

Global prevalence and dynamics of mecA and mecC genes in MRSA: Meta-meta-analysis, meta-regression, and temporal investigation

Journal of Infection and Public Health
This study aimed to conduct first robust meta-meta-analysis on mecC and mecA-positive MRSA strains, determining their overall prevalence and temporal trends. It encompassed 14 meta-analyses, involving 322,269 samples from 553 index studies.
