Weeksella virosa DSM 16922

Weeksella virosa (strain ATCC 43766 / DSM 16922 / JCM 21250 / NBRC 16016 / NCTC 11634 / CL345/78) is a strictly aerobic, chemoorganotrophic, nonsaccharolytic Gram-negative bacterium isolated from genitourinary tract samples, predominantly from women, in North Carolina, USA. W. virosa are also detected by cultural methods in the oral cavity, the genitourinary tract of man, in clinical specimens of pigs, the urine of a cow with bladder carcinoma, and in the midgut of a Brazilian dipteran. W. virosa occurs mainly as an inhabitant of mucosa of warm-blooded animals and healthy man. The cells are rod-shaped with parallel sides and rounded ends. Colonies on nutrient agar appear circular and low convex with entire edges, smooth, shining and mucoid, reaching 2mm in diameter after 24h. Most strains produce a diffusible dark brown pigment on tyrosine-containing agar. W. virosa grows at 42 degrees Celsius but not at 5 degrees Celsius. It is able to utilize beta-hydroxybutyrate as a substrate and to produce indole. W.virosa is susceptible to most beta-lactams, tetracycline, chloramphenicol, nalidixic acid, erythromycin and sulfamethox-azole-trimethoprim.
