Staphylococcus haemolyticus
Scientific classification
Kingdom: Bacteria
Phylum: Firmicutes
Class: Bacilli
Order: Bacillales
Family: Staphylococcaceae
Genus: Staphylococcus
Species: S. haemolyticus
Binomial name
Staphylococcus haemolyticus
Schleifer & Kloos 1975

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Overview

Staphylococcus haemolyticus is a species of bacterium belonging to the genus Staphylococcus. It is a Gram positive coccus, coagulase negative, and catalase positive. Frequently found as a commensal organism on the skin of humans and animals, S. haemolyticus occurs infrequently as a cause of soft-tissue infections, usually in immunocompromised patients.

S. haemolyticus is resistant to multiple antimicrobial agents.[1] Resistance to vancomycin has been recorded, and this is a cause for concern because such resistance could be acquired by other, more pathogenic staphylococci.

Treatment

Antimicrobial regimen

  • 2. Methicillin-resistant Staphylococcus epidermidis
  • Preferred regimen: Vancomycin 1 g IV q12h with or without Rifampin 600 mg/day PO qd
  • Note: For deep-seated infections consider adding Gentamicin with or without Rifampin 600 mg/day PO qd to the regimen[4]
  • 3. Prosthetic device infections
  • Preferred regimen: Oxacillin 1-2 g IV q4h ((or) Vancomycin 1 g IV q12h) AND Rifampin 600 mg/day PO qd AND Gentamicin 3 mg/kg/day IV/IM q8-24h is appropriate[4]
  • Note: Duration depends on site of infection and severity.
