Genome data cross-contamination versus interdomain recombination: Equus caballus and Mus musculus genetic loci in the insertion sequence-rich genomes of two clonally related methicillin-resistant Staphylococcus aureus strains from China.

ABSTRACT:

Background

Methicillin-resistant Staphylococcus aureus (MRSA) represents a significant global health threat, responsible for infections in both humans and animals. Determining genetic patterns associated with the genome plasticity of MRSA is critical for predicting the evolutionary trajectories of its emerging pathogenic clones.

Results

The specific genetic loci of the MRSA strains WH3018 and WH9628 from Wuhan, China, ranging in size from 399 to 3,622 base pairs, were determined to be highly homologous (DNA identity: 90.95-100%) to corresponding chromosomal regions from Equus caballus and Mus musculus in the GenBank database. These eukaryotic-associated loci included the microsatellite DNAs or Y chromosome-specific regions from E. caballus, or 45 S-28 S ribosomal RNA/H19 loc
