Emergence and spread of a new community-genotype methicillin-resistant Staphylococcus aureus clone in Colombia.

ABSTRACT:

Background

Community-genotype methicillin-resistant Staphylococcus aureus (CG-MRSA) clones are a global concern due to their resistance and increased virulence and their ability to cause infections both hospitalized patients and healthy people in the community. Here, we characterize 32 isolates of a new CG-MRSA clone. These isolates were identified in four cities in Colombia, South America.

Methods

The isolates were recovered from four different epidemiological and prospective studies that were conducted in several regions of Colombia. Molecular characterizations included multilocus sequence typing; pulsed-field gel electrophoresis; SCCmec, agr and spa typing; and whole-genome sequencing.

Results

All isolates belonged to ST923 (clonal complex 8), harbouring SCCmec IVa
