“…pestis was analyzed, however, the taxonomic significance of this difference is questionable. Thus, the genus Yersinia appears to be homogeneous, and the fatty acid data on the yersiniae do not reflect the apparent taxonomic distance between Y. enterocolitica and Y. pseudotuberculosis as observed by DNA-DNA hybridization experiments (3,19). A reference group of five strains of Salmonella typhi was included in the study to determine the taxonomic position of Yersinia relative to another group of Enterobacteriaceae.…”

“…enterocolitica seems to be relatively distant from both Y. pseudotuberculosis and Y . pestis (3,19). Actually, the genetic affinities between Y. enterocolitica and Y. pseudotuberculosis strains were found to be so weak that Moore and Brubaker (19) questioned the inclusion of Y .…”

“…The medically significant yersiniae are Yersinia pestis, the causative agent of bubonic plague, the very closely related Yersinia pseudotuberculosis, and the more divergent Yersinia enterocolitica (Achtman et al, 1999;Moore & Brubaker, 1975). All three species share a similar~70 kb plasmid, termed pCD in Y. pestis and pYV in enteropathogenic Y. pseudotuberculosis and Y. enterocolitica.…”

Growth of calcium-blind mutants of Yersinia pestis at 37 °C in permissive Ca2+-deficient environments

et al. 2009

Cells of wild-type Yersinia pestis exhibit a low-calcium response (LCR) defined as bacteriostasis with expression of a pCD-encoded type III secretion system (T3SS) during cultivation at 37 °C without added Ca2+ versus vegetative growth with downregulation of the T3SS with Ca2+ (≥2.5 mM). Bacteriostasis is known to reflect cumulative toxicity of Na+, l-glutamic acid and culture pH; control of these variables enables full-scale growth (‘rescue’) in the absence of Ca2+. Several T3SS regulatory proteins modulate the LCR, because their absence promotes a Ca2+-blind phenotype in which growth at 37 °C ceases and the T3SS is constitutive even with added Ca2+. This study analysed the connection between the LCR and Ca2+ by determining the response of selected Ca2+-blind mutants grown in Ca2+-deficient rescue media containing Na+ plus l-glutamate (pH 5.5), where the T3SS is not expressed, l-glutamate alone (pH 6.5), where l-aspartate is fully catabolized, and Na+ alone (pH 9.0), where the electrogenic sodium pump NADH : ubiquinone oxidoreductase becomes activated. All three conditions supported essentially full-scale Ca2+-independent growth at 37 °C of wild-type Y. pestis as well as lcrG and yopN mutants (possessing a complete but dysregulated T3SS), indicating that bacteriostasis reflects a Na+-dependent lesion in bioenergetics. In contrast, mutants lacking the negative regulator YopD or the YopD chaperone (LcrH) failed to grow in any rescue medium and are therefore truly temperature-sensitive. The Ca2+-blind yopD phenotype was fully suppressed in a Ca2+-independent background lacking the injectisome-associated inner-membrane component YscV but not peripheral YscK, suggesting that the core translocon energizes YopD.
