Abstract

ABSTRACT Staphylococcus aureus clonal complex 398 (CC398) isolates colonize livestock and can spread to human contacts. Genetic analysis of isolates epidemiologically associated with human-to-human, but not livestock, transmission in multiple countries and continents identified a common clade that was negative for tet (M) and positive for bacteriophage ϕ3. Another group of human-to-human-transmitted isolates belonged to the common livestock-associated clade but had acquired a unique ϕ7 bacteriophage.
