Yersinia enterocolitica invasin: a primary role in the initiation of infection.

The ability to invade the intestinal epithelium of mammals is an essential virulence determinant of Yersinia enterocolitica. The chromosomally encoded Y. enterocolitica 8081v invasion gene, inv, was disrupted to assess its role in pathogenesis.

Tongue abscess: case report and review.

Tongue abscesses are extremely rare infections despite the relatively frequent exposure of the tongue to bite trauma during mastication and seizures. We describe a case of tongue abscess in a 40-year-old man and discuss the pathophysiology, diagnosis, and treatment of this entity.

The Yersinia enterocolitica inv gene product is an outer membrane protein that shares epitopes with Yersinia pseudotuberculosis invasin.

An essential virulence attribute for Yersinia enterocolitica and Yersinia pseudotuberculosis is the ability to invade the intestinal epithelium of mammals. The chromosomal invasin gene (inv) has been cloned from both of these Yersinia species, and the Y. pseudotuberculosis invasin has been well characterized (R.

Hemispheric asymmetry in the processing of high and low spatial frequencies: a facial recognition task.

The research investigated the relationship between spatial frequency and visual field in a facial recognition task. Faces of neutral affect (Ekman, 1979) were tachistoscopically presented to the right or left visual field. The faces were presented alone, or masked with square wave gratings of 1, 24, or 48 cycles/degree, for a duration of 10 msec.
