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.
