Abstract
This study aimed to characterize
Staphylococcus aureus
(
S. aureus
) strains isolated from human infections in Mongolia. Infection samples were collected at two time periods (2007–08 and 2011) by the National Center for Communicable Diseases (NCCD) in Ulaanbaatar, Mongolia.
S. aureus
isolates were characterized using polymerase chain reaction (PCR) for
mecA
, PVL, and
sasX
genes and tested for
agr
functionality. All isolates were also
spa
typed. A subset of isolates selected by frequency of
spa
types was subjected to antimicrobial susceptibility testing and multilocus sequence typing. Among 251
S. aureus
isolates, genotyping demonstrated methicillin resistance in 8.8% of isolates (22/251). Approximately 28% of the tested
S. aureus
isolates were observed to be multidrug resistant (MDR). Sequence type (ST) 154 (
spa
t667) was observed to be a strain with high virulence potential, as all isolates for this
spa
type were positive for PVL, had a functional
agr
system and 78% were MDR.
S. aureus
isolates of ST239 (
spa
t037) were observed to cause infections and roughly 60% had functional
agr
system with a greater proportion being MDR. Additionally, new multilocus sequence types and new
spa
types were identified, warranting continued surveillance for
S. aureus
in this region.
