Epidemiologic investigations of Yersinia enterocolitica and related species: sources, frequency, and serogroup distribution.
During an 11-year period (1978 to 1989), over 300 strains of Yersinia spp. (excluding Y. pestis and Y. pseudotuberculosis) were recovered from a variety of gastrointestinal and extraintestinal sites in patients in California. Over the 11-year period, Y. enterocolitica serogroup O:3 predominated, although a shift in the relative frequency of this serogroup was observed during this interval, incr...
متن کاملSerogroup-related escape of Yersinia enterocolitica YopE from degradation by the ubiquitin-proteasome pathway.
Pathogenic Yersinia spp. employ a type III protein secretion system that translocates several Yersinia outer proteins (Yops) into the host cell to modify the host immune response. One strategy of the infected host cell to resist the bacterial attack is degradation and inactivation of injected bacterial virulence proteins through the ubiquitin-proteasome pathway. The cytotoxin YopE is a known ta...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولIn vitro assessment of virulence in Yersinia enterocolitica and related species.
We have examined 136 isolates of Yersinia species, comprising 112 strains of Yersinia enterocolitica, 12 of Y. frederiksenii, 8 of Y. intermedia, and 5 of Y. kristensenii, for the presence of 40- to 50-megadalton virulence-associated plasmids and expression of the following plasmid-associated characteristics: Congo red pigmentation (CR), calcium dependence, autoagglutination, hydrophobicity, re...
