Staphylococcus hominis

STRUCTURE AND PHYSIOLOGY

S.hominisis a facultatively anaerobic, Gram-positive cocci generally found on human and animal skin, typically preferring more moist areas such as the axillae and pubic regions. S. hominis produces thioalcohol compounds, which contribute to body odor.

TRANSMISSION AND DISEASE

Though usually a harmless commensal microorganism, S. hominis can cause illness in immunosuppressed patients, such as those undergoing chemotherapy. While generally susceptible to most antibiotics, over 20 antibiotic-resistant strains have been discovered, including S. hominis subspecies novobiosepticus.

DISINFECTION

Due to its prevalence in the environment, S. hominis is a common target when evaluating facilities for contamination.
