Staphylococcus haemolyticus is a member of the coagulase-negative staphylococci (CoNS).[2] It is part of the skin flora of humans,[3] and its largest populations are usually found at the axillae, perineum, and inguinal areas.[4] S. haemolyticus also colonizes primates and domestic animals.[4] It is a well-known opportunistic pathogen, and is the second most frequently isolated CoNS (S. epidermidis is the first).[5] Infections can be localized or systemic, and are often associated with the insertion of medical devices.[6][7][8] The highly antibiotic resistant phenotype and ability to form biofilms make S. haemolyticus a difficult pathogen to treat.[5]
