* It finds that antibiotic treatment in humans and non-human primates (NHPs) correlates with a higher prevalence of MRSA compared to wild species like micromammals and bats, indicating that antibiotic pressure influences resistance acquisition.
* The research suggests that generalist MRSA strains, those that can infect various hosts, have a higher potential for spreading antibiotic resistance than specialist strains, highlighting the importance of host diversity in the dynamics of antibiotic resistance in ecosystems.
Objectives: We aimed at determining whether specific S. aureus strains cause infective endocarditis (IE) in the course of Staphylococcus aureus bacteraemia (SAB).
Methods: A genome-wide association study (GWAS) including 924 S.
