Isolamento de possível espécie nova de chromobacterium em águas poluídas

Resumo

A new bacterium was isolated from a small brook, of the Genus Chromobacterium but whose species was not identified yet. It is believcd to be a Chromobacterium with different characteristics from the known species violaceum and ianthinum, according to the tests listed below: Rods — 0,3 to 0,5 by 1,5 to 4,0 micra, occurring single. Gram-negative. --' : - . : : . . ; - , . .- Motile with a monothrichous flagellum-v' .Agar colonies; circular, violet. Nitrites produced from nitrates. Gelatin stab — no liquefation. Thioglycollate broth: turbid, with light violei pellicle and violei sediment. OUtmus milk:,,slDW coagulation. litmus decolorízed on the fifth day. Potato dexfrose agar: slow pigmentation, spreading growth. índole: not fonned. VM: negative. Voges-Proskauer: negatíve. Simmons: citfate: positive. Acid from glucosc with CO2. No acid from maltose, lactose, sucrose, mannitoí, dulcitol, salicin, inositol, mannosc and inulin. Strict aerobic. Optimum temperature: 37.°C. No growth at 2 tu 4.°C. McConkey: circular, light violet. Blood agar: hcmolytic colonies. Desoxicolatecitrate agar (SS agar médium): no growth. Pigment soluble in alcohol, chloroform, saline and éter sulfuric acid, and insoluble in acetic acid, destilled water and NaOH (40%). Pathogenic for mouse (300.000 bact/mil), but not causing septicemia on inoculation of 1.000 at 10.000 bact/ml (intraperitoneal) . This species probably causes fatal septicemiai in some manimals especially in pigs.
