Structural Comparison of Three Types of Staphylococcal Cassette Chromosome mec Integrated in the Chromosome in Methicillin-Resistant Staphylococcus aureus

Ito, Teruyo, Katayama, Yuki, Asada, Kazumi, Mori, Namiko, Tsutsumimoto, Kanae, Tiensasitorn, Chuntima, ...

The β-lactam resistance gene mecA of Staphylococcus aureus is carried by a novel mobile genetic element, designated staphylococcal cassette chromosome mec (SCCmec), identified in the chromosome of a...

Genetic Organization of the Chromosome Region Surrounding mecA in Clinical Staphylococcal Strains: Role of IS431-Mediated mecI Deletion in Expression of Resistance in mecA-Carrying, Low-Level Methicillin- Resistant Staphylococcus haemolyticus

Katayama, Yuki, Ito, Teruyo, Hiramatsu, Keiichi

We report on the structural diversity of mecA gene complexes carried by 38 methicillin-resistant Staphylococcus aureus and 91 methicillin-resistant coagulase-negative Staphylococcus strains of seven...

Identification in Methicillin-Susceptible Staphylococcus hominis of an Active Primordial Mobile Genetic Element for the Staphylococcal Cassette Chromosome mec of Methicillin-Resistant Staphylococcus aureus

Katayama, Yuki, Takeuchi, Fumihiko, Ito, Teruyo, Ma, Xiao Xue, Ui-Mizutani, Yoko, Kobayashi, Ichizo, ...

We previously reported that the methicillin resistance gene mecA is carried by a novel type of mobile genetic element, SCCmec (staphylococcal cassette chromosome mec), in the chromosome of...

Jumping the Barrier to β-Lactam Resistance in Staphylococcus aureus

Katayama, Yuki, Zhang, Hong-Zhong, Hong, Dong, Chambers, Henry F.

Although the staphylococcal methicillin resistance determinant, mecA, resides on a mobile genetic element, staphylococcus cassette chromosome mec (SCCmec), its distribution in nature is limited to as...

PBP 2a Mutations Producing Very-High-Level Resistance to Beta-Lactams

Katayama, Yuki, Zhang, Hong-Zhong, Chambers, Henry F.

Resistance to the beta-lactam class of antibiotics in methicillin-resistant Staphylococcus aureus (MRSA) is mediated by PBP 2a, a synthetic bacterial cell wall penicillin-binding protein with a low...

Genetic Background Affects Stability of mecA in Staphylococcus aureus

Katayama, Yuki, Robinson, D. Ashley, Enright, Mark C., Chambers, Henry F.

The staphylococcal methicillin resistance determinant, mecA, resides on a mobile genetic element, staphylococcus chromosomal cassette mec (SCCmec). The distribution of SCCmec in nature is limited to...
