Staphylococcus pasteuri is a species of Gram-positive, catalase-positive, coagulase-negative bacteria in the genus Staphylococcus. It was first described in 1993 from human clinical samples.¹

Ecology

It has been found on human skin, in indoor air, pasteurised dairy products, environmental surfaces,¹ and the lower gastrointestinal tract of pigs.²

Clinical significance

Though rare, S. pasteuri can act as an opportunistic pathogen. Documented infections include native-valve infective endocarditis,³ chronic post-traumatic osteomyelitis,⁴ and bacteraemia in a leukemia patient.⁵ Clinical isolates often show resistance to β-lactams and macrolides, but remain susceptible to glycopeptides like vancomycin and to linezolid.¹

Etymology

The species name pasteuri honors Louis Pasteur.¹
