Historical synonyms:
Corynebacterium seminale Riegel, Ruimy, De Briel, Prevost, Jehl, Bimet, Christen and Monteil 1996 is a later
heterotypic synonym of
C. glucuronolyticum.
Gram-positive coryneform rods, 1-3 µm in length.
Colonies are white-yellowish, non-hemolytic, convex, 1.0-1.5 mm in diameter after 24
hours of incubation at 37 ºC on sheep blood agar. CAMP test is positive. Optimum
growth temperature is 37 ºC. weak growth at 30 or 42 ºC. No growth at 25 ºC.
Supplementation with CO
2 enhances the growth.
Isolated from urogenital tract of humans (may be part of the normal flora) and pigs (semen of boars, uterine and vaginal secretions of
sows) and from male patients with genitourinary infections.
Susceptible to beta-lactams, gentamicin, rifampin and vancomycin.
A relatively high proportion of strains are resistant to ciprofloxacin, clindamycin, erythromycin and tetracycline.
Isolated from male patients with genitourinary infections. It's a human pathogen: may cause prostatitis or urethritis.

Non-partially-acid-fast. Fermentative metabolism. Lactate and succinate are produced.

Positive results for amylase, catalase, beta-glucuronidase, leucine arylamidase,
pyrazinamidase, acid production from: glucose &  sucrose.

Negative results for lipophilism, gelatin hydrolysis, tyrosine hydrolysis, acid production from: mannitol, lactose, trehalose & glycogen.

Variable results for alkaline phosphatase (negative for API CORYNE and API 20 STREP), esculin hydrolysis, hippurate hydrolysis,
nitrate reduction, urease, acid production from: arabinose, arbutin, maltose, ribose, salicin & xylose.
