Oligella species are gram-negative organisms that cause infection primarily of the genitourinary tract.
The genus Oligella contains 2 species, Oligella urethralis and Oligella ureolytica.
O. urethralis is a commensal of the genitourinary tract, and most clinical isolates are from the urine, predominantly from men. Although symptomatic infections are rare, bacteremia, septic arthritis that mimics gonococcal arthritis, and peritonitis in patients who need chronic ambulatory peritoneal dialysis have been reported.
O. ureolytica
Diagnosis of Oligella infections is by culture.
