Leminorella

Abstract

Le.mi.no.rel' la . M.L. dim. ‐ ella ending; M.L. fem. n. Leminorella named to honor Leon Le Minor, a French microbiologist, for his many contributions to enteric bacteriology including the nomenclature, classification, and serotyping of Salmonella ; lysogeny; metabolic plasmids; and new and rapid biochemical tests. The name also honors Simone Le Minor, who also made many contributions to enteric bacteriology as head of the National Salmonella Centre of France and for her research on Serratia serotyping. Proteobacteria / Gammaproteobacteria / Enterobacteriales / Enterobacteriaceae / Leminorella Small rod‐shaped cells, conforming to the general definition of the family Enterobacteriaceae . Gram‐negative. Nonmotile at 36°C and 25°C . Contain the enterobacterial common antigen. Facultatively anaerobic. Catalase positive (strong and rapid). Oxidase negative. Nonpigmented. Ferment, rather than oxidize, D ‐glucose. Reduce nitrate to nitrite. Inactive biochemically. Positive for H 2 S production ( TSI and PIA ), tyrosine hydrolysis, and fermentation of L ‐arabinose , d ‐ xylose, and L ‐tartrate . Negative for indole production, Voges–Proskauer, urea hydrolysis, phenylalanine deaminase, lysine decarboxylase, arginine dihydrolase, ornithine decarboxylase, growth in the presence of cyanide (KCN test), malonate utilization, esculin hydrolysis, gelatin hydrolysis (22°C), lipase (corn oil), DNase, and the fermentation of lactose, sucrose, D ‐mannitol, salicin, adonitol, myo ‐inositol, D ‐sorbitol, raffinose, L ‐rhamnose, maltose, trehalose, cellobiose, α‐methyl‐ D ‐glucoside, erythritol, melibiose, D ‐arabitol, glycerol, D ‐mannose, and D ‐galactose. Susceptible to colistin, nalidixic acid, sulfadiazine, gentamicin, kanamycin, tetracycline, chloramphenicol; resistant to streptomycin, penicillin, ampicillin, carbenicillin, and cephalothin (disk diffusion method on Mueller‐Hinton agar). The mol % G + C of the DNA is : not reported. Type species : Leminorella grimontii Hickman‐Brenner, Vohra, Huntley‐Carter, Fanning, Lowery, Brenner and Farmer 1985c, 375 (Effective publication: Hickman‐Brenner, Vohra, Huntley‐Carter, Fanning, Lowery, Brenner and Farmer 1985b, 235.)
