Movement and Stability of the Staphylococcal Cassette Chromosome mec among Staphylococcus aureus
Methicillin-resistant Staphylococcus aureus (MRSA) is a well-known public health concern. However, numerous aspects concerning the natural transfer and stability of the methicillin resistance genes and staphylococcal cassette chromosome mec (SCCmec) carrying them remains unknown. Older scientific …

Carriage rate of staphylococcus aureusamong healthcare workers at the University Teaching Hospital in Lusaka
… Antimicrobial susceptibility testing, including methicillin resistance was determined using the disc diffusion method, while molecular analysis of the isolates was achieved by spa typing. The overall S. aureus carriage among the health care workers was 17.1% (24/140).Of these, 13.6% (19/140) and …

Improved monitoring of emerging environmental biocontaminants through (nano)biosensors and molecular analyses
… for contributing to the spread of antibiotic resistance. Antibiotic resistance arises from mutations and/or sharing of antibiotic resistance genes (ARGs) among bacteria via horizontal gene transfer, with carriage of ARGs by pathogenic bacteria of particular concern to human health. While most …

GENOMIC DIVERSITY IN Staphylococcus Aureus
… aureus</em> chromosomal DNA from 125 methicillin-resistant and 10 methicillin-sensitive clinical isolates was digested with rare-cutting restriction endonucleases and subjected to pulsed-field gel electrophoresis (PFGE). Thirty-nine distinct genomic macrorestriction patterns (GPs) were …

Genomic investigation into the evolution of <i>Staphylococcus aureus</i> and the micro-epidemiology of <i>Staphylococcus aureus </i>in atopic eczema
… adaptation is the development of drug resistance. Methicillin resistant Staphylococcus aureus (MRSA) was first observed in 1960, less than one year after the introduction of the drug into clinical practice. Previous epidemiological and genetic evidence has always suggested that MRSA …

A multi-omics perspective on the biology and evolution of the genus Macrococcus
… for these organisms to serve as reservoirs of methicillin resistance determinants. Considering that strains of the M. caseolyticus species have been associated with flavour development in dairy and fermented meat products, further investigation of this fascinating genus, and the species within …

MRSA: A Global Threat
Methicillin-resistant Staphylococcus aureus (MRSA) is the cause to some of the most common infections in the world. Its molecular distribution does not show the dissemination of one global strain. Studies show that, although community-acquired MRSA is more common in the United States, …

Defining the Aetiology and Antimicrobial Susceptibility Patterns of the Predominant Bacteria Associated with Bloodstream Infections at the Hospital for Tropical Diseases in Ho Chi Minh City, Vietnam
… According to many multinational antimicrobial resistance surveillance schemes, Asia represents a substantial reservoir of clinically relevant antimicrobial resistant genes. These genes include extended spectrum Beta lactamases (ESBLs) and AmpC lactamases in the Enterobacteriaceae, …

Characterization Of Antimicrobial-Resistant staphylococcus Spp. In Food Animals And Retail Meat
<p>Antimicrobial resistance in <i>Staphylococcus</i> spp. is a worldwide epidemic concern in hospital and community settings. Food animals and retail meat are important reservoirs of these pathogens that can pose potential threat to humans. In this dissertation, we aimed to investigate the …

Staphylococcus aureus en animales de vida libre y medioambiente. Resistencia a antimicrobianos, virulencia, líneas genéticas circulantes y genómica comparativa
… but it can also be opportunistic pathogens. Methicillin-resistant S. aureus (MRSA) is a serious health problem since it shows resistance to almost all β-lactam antibiotics. In 2005, for the first time, a genetic MRSA clonal complex CC398 was detected associated with livestock (MRSA-LA), whose …

Characterization of the Factors Associated with SCCmec Mobility in Staphylococcus Aureus
The gene encoding resistance to β-lactam antibiotics in the staphylococci is found on the chromosome in a genomic island designated Staphylococcal Chromosome Cassette mec or SCCmec. In addition to the resistance gene, mecA, SCCmec also contains site specific recombinase genes, ccrAB, that are …
