E.YR 1983 T1 Providencia friedericiana, a New Species Isolated from Penguins JF International Journal of Systematic and Evolutionary Microbiology, VO 33 IS 4 SP 709 OP 715 DO https://doi.org/10.1099/00207713-33-4-709 PB Microbiology Society, SN 1466-5034, AB The name Providencia friedericiana sp. nov. is proposed for a well-defined group of organisms that were isolated from fecal specimens from penguins (Aptenodytes patagonica, Eudyptes crestatus, Pyoscelis papua, Spheniscus demersus, and Spheniscus humboldti). P. friedericiana strains are gram-negative, oxidase-negative, fermentative rods that grow on Endo agar, MacConkey agar, Wilson-Blair agar, and some other selective media for Enterobacteriaceae. They are acetate, adonitol, arginine dihydrolase, gelatinase, inositol, lactose, lysine decarboxylase, mannitol, ornithine decarboxylase, tartrate, trehalose, urease, and Voges-Proskauer negative, but fructose, galactose, glucose, glycerol, indole, catalase, KCN, nitrate reductase, mannose, methyl red, and phenylalanine deaminase positive. Simmons citrate is utilized weakly and variably. Gas is produced from glucose in small amounts or not at all. The organisms possess flagella when they are grown at 25°C. They show moderate motility at 25°C but are nonmotile or only slightly motile at 36°C. Capsules and slime layers are not produced. The type strain of P. friedericiana, strain 1/33, has been deposited with the Deutsche Sammlung von Mikroorganismen as strain DSM 2620., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-33-4-709
