Latest revision as of 11:19, 21 November 2022

Group of Gram-positive cocci that are catalase positive and coagulase negative

Organisms

Staphylococcus epidermidis group
Staphylococcus haemolyticus group
Staphylococcus saprophyticus: mainly causes UTIs
Staphylococcus massiliensis
Staphylococcus lugdenensis: has more in common with Staphylococcus aureus and should never be considered a contaminant
Unclear grouping

Management

Generally resistant to β-lactams
First-line: vancomycin
Alternatives: linezolid, daptomycin, co-trimoxazole, ciprofloxacin, doxycycline
