Evidence for the evolutionary steps leading to mecA-mediated β-lactam resistance in staphylococci. [PDF]

open access: yesPLoS Genetics, 2017
The epidemiologically most important mechanism of antibiotic resistance in Staphylococcus aureus is associated with mecA-an acquired gene encoding an extra penicillin-binding protein (PBP2a) with low affinity to virtually all β-lactams.

Ceftaroline resistance in Staphylococcus pseudintermedius gene mecA carriers [PDF]

open access: yesPesquisa Veterinária Brasileira, 2018
ABSTRACT: Infections caused by methicillin-resistant Staphylococcus aureus (MRSA) being a constant concern, ceftaroline fosamil has been recently approved as a new cephalosporin, active against MRSA, for use in humans; only rare cases of resistance have been reported till date.

Prevalence of Methicillin-ResistantStaphylococcus aureus and Multidrug-Resistant Strains from Patients Attending the Referral Hospitals of Amhara Regional State, Ethiopia

open access: yesInternational Journal of Microbiology, 2023
Background. Staphylococcus aureus (S. aureus) causes different types of human infections and can develop resistance to many antibiotics. There is a scarcity of data on the mecA gene and multidrug-resistant (MDR) strain distribution of this organism in ...

mecA Gene Is Widely Disseminated in Staphylococcus aureus Population [PDF]

open access: yesJournal of Clinical Microbiology, 2002
ABSTRACT Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most important causes of hospital infections worldwide. High-level resistance to methicillin is caused by the mecA gene, which encodes an alternative penicillin-binding protein, PBP 2a. To determine the clonal

Methicillin-resistance in Staphylococcus aureus is not affected by the overexpression in trans of the mecA gene repressor: a surprising observation. [PDF]

open access: yesPLoS ONE, 2011
Methicillin-resistant Staphylococcus aureus (MRSA) is intrinsically cross-resistant to virtually all β-lactam antibiotics. The central determinant for the MRSA phenotype is the mecA gene, whose transcriptional control may be mediated by a repressor (mecI)

Vancomycin-induced deletion of the methicillin resistance gene mecA in Staphylococcus aureus [PDF]

open access: yesJournal of Antimicrobial Chemotherapy, 2004
To elucidate factors that contribute to the development of vancomycin resistance in methicillin-resistant Staphylococcus aureus (MRSA).Forty-nine MRSA isolates were subjected to passage selection with vancomycin to isolate mutants with reduced susceptibility to vancomycin.

MRSA/MSSA causing infections: prevalence of mecA gene

open access: yesEuropean Journal of Public Health, 2020
Abstract Introduction Staphylococcus aureus is part of the human flora, present in the skin and mucous membranes but can become pathogenic, causing a wide spectrum of infections that were initially treated with penicillin. However, were observed some strains with resistance to this antibiotic and, therefore was developed a new antibiotic,

Identification of MRSA(methicillin resistant Staphylococcus aureus) by mecA gene

open access: yesAl-Salam Journal for Medical Science, 2022
Staphylococcus aureus is a bacterium that may be found in the skin and upper respiratory system. Although S.aureus is a normal flora, it has evolved into an opportunistic pathogen that causes numerous infections that are difficult to cure due to the presence of virulence genes.

Distribution of MecA and Erm Genes among Methicillin-resistant Staphylococcus Aureus with Inducible Resistance to Clindamycin

open access: yesJournal of Nepal Health Research Council, 2023
Background: The emergence of Methicillin-resistant Staphylococcus aureus and its ability to confer cross-resistance to macrolide-lincosamide-streptogramin B has complicated the treatment against it.

STUDYING THE FREQUENCY OF METHICILLIN-RESISTANT STAPHYLOCOCCUS AUREUS THROUGH THE MOLECULAR DETECTION OF MECA

open access: yesThe Iraqi Journal of Medical Sciences, 2016
Background: Methicillin-resistant Staphylococcus aureus is a major cause of serious nosocomial infections and it is very important to have a reliable test to detect these bacteria.
