Microbiology
- Gram-positive coccus
- Notable species
- Aerococcus urinae, which causes urinary tract infections
- Aerococcus sanguinicola, causes UTIs, but sometimes a contaminant
- Aerococcus viridans, often a contaminant
- Presumed resistance in vivo to TMP-SMX, even though it may appear susceptible in vitro
- It can acquire folate from the host's urine, counteracting the antibiotic
Clinical Manifestations
- A. urinae causes UTI and endocarditis (often following UTI in older men)
Management
- Penicillin ± aminoglycoside (for synergy, based on in vitro studies)
