aYps: Y. pestis; Yptb: Y. pseudotuberculosis; Ye: Y. enterocolitica. ^Nonpathogenic strains are negative.

cThe 68-kb pgm locus is present in Y. pseudotuberculosis but is usually silent.

dIn some strains of Y. pestis, ail is interrupted by a copy of IS285, but in others, this locus is intact.[2]

eThe + + and + refers to the higher number of these insertion sequence elements or relative intensity of the LCR seen in Y. pestis vs. Y. pseudotuberculosis and Y. enterocolitica, respectively.

fY. enterocolitica does not harbor copies of IS100.

gMetabolic capability known to undergo reversion.

when grown at room temperature but nonmotile when grown at 37°C.[1] In contrast, Y. pestis is nonmotile at all tested growth conditions. Strain CO92 appears to have an intact set of flagella genes,[2] whereas KIM encodes a mutant flhD flagella regulatory element.[3] It remains to be determined if there are environmental conditions that Y. pestis might become motile.

Generally, the growth of Y. pestis is more fastidious at 37°C than is growth of the enteropathogenic species. The growth rate of Y. pestis is not enhanced when cultivated at 37°C compared with 26°C, whereas the rate of cell division is enhanced for the enteropathogenic Yersinia. This fact is partially a result of a larger number of nutritional requirements by Y. pestis at the higher growth temperature as well as a more pronounced low calcium response (requirement for millimolar amounts of calcium for growth at 37°C) by this species.[4]

Getting Started With Dumbbells

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
