Non-motile, non-sporulating, facultatively anaerobic, and Gram-stain positive.
Member of the coagulase-negative staphylococci (CoNS).
It is part of the skin flora of humans, and its largest populations are usually found at the axillae, perineum, and inguinal areas.
It is a well-known opportunistic pathogen, and is the second most frequently isolated CoNS (S. epidermidis is the first).
Infections can be localized or systemic, and are often associated with the insertion of medical devices.
The highly antibiotic resistant phenotype and ability to form biofilms make S. haemolyticus a difficult pathogen to treat.
Therapy:
Important considerations: The choice of an agent should be based on local antimicrobial sensitivities, site of infection, cost, and comorbid conditions. Generally, the most common agents/regimens are listed first. Listed dosages may need to be adjusted for renal dysfunction.
S. haemolyticus has the highest level of antibiotic resistance among the (CoNS) coagulase-negative staphylococci
