Staphylococcus schleiferi diabetic foot osteomyelitis and bacteraemia in an immunocompromised host.

Staphylococcus schleiferi is a Gram-positive coccus bacterium first discovered in 1988 that is typically associated with skin and ear infections in dogs, cats and birds. It is infrequently described as a human pathogen. There are, however, emerging reports of S. schleiferi infections in diverse clinical scenarios in humans, particularly in patients with weakened immune systems. S. schleiferi may be underrecognised due to limitations in routine microbiology diagnostic protocols and mislabelling as other Staphylococcus sp. We present a rare case of S. schleiferi diabetic foot osteomyelitis with subsequent bacteraemia in an immunocompromised host.
