Pigs are the only known animal reservoir of Yersinia enterocolitica strains pathogenic to humans. In this study 106 ail-positive pathogenic Y. enterocolitica isolates, previously recovered from 2793 swine fecal samples (3.8%) collected during National Animal Health Monitoring System's Swine 2000 study, were examined. The presence of the previously described virulence plasmid, expression of plas...

Yersinia pestis cells were grown in vitro at 26 and 37 degrees C, the ambient temperatures of its flea vector and its mammalian hosts, respectively, and subjected to subcellular fractionation. Abundance changes at 26 vs 37 degrees C were observed for many outer-membrane (OM) proteins. The cell adhesion protein Ail (y1324) and three putative small beta-barrel OM proteins (y1795, y2167 and y4083)...

Exercise is essential for health, yet the amount, duration, and intensity that individuals engage in are strikingly variable, even under prescription. Our focus was to identify the locations and effects of quantitative trait loci (QTL) controlling genetic predisposition for exercise-related traits, utilizing a large advanced intercross line (AIL) of mice. This AIL (G(4)) population originated f...

In a discussion of energy metabolism in the elderly, we ought to try to be modestly précise about what exactly is meant by the "elderly." There is enough individual variation among a group of elderly people who are ail of the same âge to create difficult problems and if we lump together the whole âge range from 65 years onward (as is frequently done in tables of energy and nutrient requirements...

A complex problem is solved herej we show how to write Dyson's equations for trie (Ising) spin-glass that relate the propagator G ta trie mass operator M. In other words we are able to reduce trie inversion of an ultrametric matrix M to the solution of a Dyson's equation in ail sectors (for the replicon sectcr trie result had already been derived). It turns oui that what renders the problem tra...

Brown rats (Rattus norvegicus) have been identified as potential carriers of Yersinia enterocolitica and Y. pseudotuberculosis, the etiological agents of yersiniosis, the third most reported bacterial zoonosis in Europe. Enteropathogenic Yersinia spp. are most often isolated from rats during yersiniosis cases in animals and humans, and from rats inhabiting farms and slaughterhouses. Information...

The synthesis, crystal structure, conductivity and electronic band structure of the new molecular metal a-(BEDT-TTF)2TlHg(Sei-~S~ CN)4 lx = 0.125) are reported. a-(BEDTTTF)2TlHg(Sei-~S~CN)4 lx = 0.125) is isostructural with ail other members of the family of o-(BEDT-TTF)2MHg(XCN)4 salts and is a stable metal down to very low temperatures. A general study of the electronic structure of ail struc...

Sensitivity to the locomotor stimulant effects of methamphetamine (MA) is a heritable trait that utilizes neurocircuitry also associated with the rewarding effects of drugs. We used the power of a C57BL/6J × DBA/2J F(2) intercross (n = 676) and the precision of a C57BL/6J × DBA/2J F(8) advanced intercross line (Aap: B6, D2-G8; or F(8) AIL; n = 552) to identify and narrow quantitative trait l...

The 150 Y enterocolitica strains isolated from humans and from pigs belonged to biotypes 4 (68.7%), 1A (18.7%) and 2 (4%), or were biochemically untypeable (8.6%). Biotype 4 was comprised of Y. enterocolitica strains representing serotype O:3, within biotype 1A the strains either belonged to serotypes O:5 and O:6 or were untypeable, and biotype 2 was represented by the strains of serotype O:9. ...
