Staphylococcal Chromosomal Cassette Type in Clinical Strains of Methicillin-Resistant Staphylococcus aureus

Kasmera, 2014
Methicillin-resistant Staphylococcus aureus (MRSA) presents a protein that binds to penicillin, the PBP2a, encoded by the gene mecA, located in a mobile genetic element called the staphylococcal chromosomal cassette (SCCmec).

Novel staphylococcal cassette chromosome mec (SCCmec) type XIV (5A) and a truncated SCCmec element in SCC composite islands carrying speG in ST5 MRSA in Japan

Journal of Antimicrobial Chemotherapy, 2019
Abstract Background Staphylococcal cassette chromosome mec (SCCmec) elements are highly diverse and have been classified into 13 types. The arginine catabolic mobile element (ACME) is an SCC-like element harbouring an arginine deiminase pathway gene cluster (ACME-arc).

MRSA CC398 recovered from wild boar harboring new SCCmec type IV J3 variant [PDF]

, 2020
A methicillin-resistant Staphylococcus aureus CC398 was recovered from a wild female boar (Sus scrofa) in the north of Portugal, in 2013 (Sousa et al. 2017).

Emergence of Livestock‐Associated Methicillin‐Resistant Staphylococcus aureus ST398 in Wild Birds, Brazil

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
In a protected forest fragment in southern Brazil, 197 wild birds were sampled, with 12.2% carrying Staphylococcus aureus. Two MRSA ST398 strains, the first reported in Brazilian wild birds, were identified. Genomic analysis revealed resistance and virulence genes, linking these strains to pigs and underscoring the critical need for resistance ...

The Host R‐M Systems Change the Host Range of Staphylococcus Phage EBHT

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
The study shows how Staphylococcal restriction–modification (R‐M) systems methylate the phage genomic DNA and change the phage host range. The host R‐M systems should be considered when selecting phage manufacturing hosts, as the manufacturing host with a higher yield can result in a narrower phage host range.

Antibiotic Resistance: A Genetic and Physiological Perspective

MedComm, Volume 6, Issue 11, November 2025.
The development of resistance to antimicrobials and their historical progression are depicted in this graphic. It draws attention to important biochemical, physiological, and genetic factors that contribute to AMR, such as the transmission of genes, the development of biofilms, and the inactivation of antibiotics.

Staphylococcal Cassette Chromosome mec, Evolution and Genetic Lines of Methicillin Resistant Staphylococcus aureus

Антибиотики и Химиотерапия, 2020
Methicillin resistant Staphylococcus aureus (MRSA) is the main pathogen of hospital- and community-associated infections. Methicillin resistance is due to mecA gene located in a mobile complex element, staphylococcal cassette chromosome mec (SCCmec). The

The prevalence, antibiotic resistance and mecA characterization of coagulase negative staphylococci recovered from non-healthcare settings in London, UK

Antimicrobial Resistance and Infection Control, 2018
Background Coagulase negative staphylococci (CoNS) are important reservoirs of antibiotic resistance genes and associated mobile genetic elements and are believed to contribute to the emergence of successful methicillin resistant Staphylococcus aureus ...
