Our objectives are:
To determine the MRSA disease burden and prevalence in humans and in animals in three countries/ areas (Bangladesh, Sri Lanka, China and Hong Kong SAR) through systematic reviews of the literature available;
Presented by Bella YANG
To identify the research gaps in the One Health context of human-animal environment interactions on MRSA in these countries;
To conduct specific studies to isolate MRSA from human, animal and environmental sources and to characterize the strains through phenotypic and molecular typing.

To understand the interrelationship between MRSA clones, their antimicrobial and biocide resistance determinants, virulence associations from a human-animal-environmental context.
A total of 564 single patient MRSA isolates from the period 2009-2016 underwent molecular characterization via whole genome sequencing (WGS). The prevalence of sequence types was as follow: ST22 (33%), followed by ST45 (32%) and ST1774 (17%) (Figure 1). Analysis is still ongoing, and another 728 strains from the period 2017-2024 are queued for WGS.
