Trabulsiella

RANK: Genus

TAXONOMY: cellular organisms -> Bacteria -> Proteobacteria -> Gammaproteobacteria -> Enterobacteriales -> Enterobacteriaceae -> Trabulsiella

OVERVIEW:

Rod-shaped cells, conforming to the general definition of the family Enterobacteriaceae. Gram negative. Motile. Facultatively anaerobic. Catalase positive. Oxidase negative. Ferment, rather than oxidize, d-glucose and other carbohydrates and produce visible gas during fermentation. Reduce nitrate to nitrite. Positive for methyl red, citrate utilization (Simmons), H2S production (TSI), lysine decarboxylase, ornithine decarboxylase, motility at 36°C, growth in the presence of cyanide (KCN test), esculin hydrolysis, ONPG, tyrosine hydrolysis, and the fermentation of d-mannitol, salicin, d-sorbitol, l-arabinose, l-rhamnose, maltose, d-xylose, trehalose, cellobiose, esculin, mucate, d-mannose, and d-galactose. Arginine dihydrolase is positive, but delayed. Negative for Voges–Proskauer, urea hydrolysis, phenylalanine deaminase, malonate utilization, gelatin hydrolysis (22°C), lipase (corn oil), DNase, and the fermentation of sucrose, dulcitol, adonitol, myo-inositol, raffinose, α-methyl-d-glucoside, erythritol, melibiose, and d-arabitol. Biochemically similar to, and can be confused with, Salmonella in routine screening tests. Do not completely type in Salmonella O or H antisera, and are negative in the Salmonella-specific test: lysis by bacteriophage O1, MUCAP (4-methylumbelliferyl caprylate), and a commercial gene probe (Gene-Trak Systems). Susceptible to colistin, nalidixic acid, gentamicin, streptomycin, kanamycin, tetracycline, chloramphenicol, and carbenicillin; resistant to penicillin, ampicillin, and cephalothin; variable resistance to sulfadiazine and carbenicillin (disk diffusion method on Mueller–Hinton agar).

The mol% G + C of the DNA is: not determined.
