>Staphylococcus Coagulase-negative species:
1] Staph epidermidis
2] Staph. haemolyticus 
3] Staph lugdunensis
4] Staph saprophyticus
5] Staph hominis
6] Staph capitis
Staphylococcus haemolyticus:
- 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.

| 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
- Vancomycin – (patient-specific regimen – trough goal 15-20 mcg/ml)
- Linezolid 600 mg orally or IV q12h
- Daptomycin 4 – 6 mg/kg IV once daily. NOT FOR PNEUMONIA
