Modern infection diseases in obstetric and gynecologic patients are caused by autoflora with the predominance of mixed (anaerobic and anaerobic/aerobic) suppuration (Barashnev, Antonov and Kudashov, 1994), and not monomicrobic
(aerobic or anaerobic) one.
Following Kass criteria, significant monomicrobic
bacteriuria was defined as culture of a single bacterial species from the urine samples at a concentration of > [10.
Columbia agar base, supplemented with 5% (vol/vol) sheep blood, and MacConkey agar plates showed a monomicrobic
culture constituted by catalase-positive and oxidase-positive gram-negative rods that did not grow under anaerobic conditions.
