Characterization of Atypical Isolates of Yersinia intermedia and Definition of Two New Biotypes

Abstract

The species Yersinia intermedia is a member of the genus Yersinia which belongs to the Enterobacteriaceae family. This species is divided into eight biotypes, according to Brenner's biotyping scheme. This scheme relies on five tests (

Population structure of the Yersinia pseudotuberculosis complex according to multilocus sequence typing

“…Fermentation of melibiose is a key test for differentiating Y. intermedia from Y. frederiksenii (Brenner et al ., 1980; Bottone et al ., 2005). However, Y. intermedia biotype 8 is incapable of fermenting melibiose, as are two other melibiose‐negative variants (Martin et al ., 2009). Within the Y. pseudotuberculosis complex, Sprague and colleagues (2008) suggested that melibiose fermentation could be used to differentiate Y. pseudotuberculosis from Y. similis .…”

Evolutionary Dynamics of the Yersinia enterocolitica Complex

“…Several different biotypes have been described based on differential utilization of Simmons citrate and fermentation of different sugars (Martin, Leclercq, Savin, and Carniel, 2009). …”

The natural and anthropogenic microbiota of Glerá, a sub-arctic river in northeastern Iceland

“…While usually considered nonpathogenic, the species Yersinia intermedia has been isolated from clinical specimens (Punsalang et al, 1987). Bacteria belonging to this species have been isolated from environmental samples like freshwater and sewage, along with various other samples like animals and food (Martin et al, 2009). Strain V10196 was found to be most similar to the human pathogen S. marcescens, with which it also shares the highly characteristic deep-red pigmentation which in this species is brought about by the trypyrrole prodigiosin (Williams et al, 1971).…”
