Aerococcus

Microbiology

Gram positive cocci, may be mistaken for a viridans streptococcus. A. christensenii, A. sanguinicola, A. urinae, A. urinaehominis, A. viridans.

Epidemiologic Risks

Usually disease in the elderly (PubMed). If you isolate an alpha streptococcus in the urine, it is likley aerococcus although the lab may not bother to identify it unless they have a MALDI-TOV, which, by the way is not a salute.

Syndromes

Usually a cystitis, especially in elderly demented men (PubMed). Positive blood cultures in a bad host, the occasional endocarditis. A. urinae espcially causes cystitis and endocarditis (PubMed).

Treatment

Penicillin. All strains of A. sanguinicola are susceptible to penicillin, ampicillin, cefuroxime, vancomycin, erythromycin, and rifampicin (PubMed). Can have increased MIC's to levofloxacin.
