Enteropathogenic Escherichia coli (EPEC) can be found in healthy and diarrheic cattle; however, little is known about the role of attaching and effacing (A/E) lesion formation in colonization of bovine intestinal mucosa by such strains. We show that typical and atypical EPEC induce A/E lesions on calf intestinal explants independently of Tir tyrosine phosphorylation and TccP. Our data support t...

Abstract Introduction: This article examines the first level of European higher education system, namely short-cycle trainings related to ISCED 5 whose Hungarian characteristics, and its historical changes were described. Methods: We examined participation rates among OECD countries. As there are large differences in Europe, we have relied on data that makes different systems comparable. Result...

When verotoxin (VT)-producing attaching and effacing Escherichia coli (AEEC, serotype O5: H-) were inoculated perorally into 10-day-old rabbits, attaching of the E. coli to enterocytes and effecting of their microvillous portion were observed extensively from the ileum to the colon. Subsequent apoptotic changes of the infected enterocytes were demonstrated by the terminal deoxynucleotidyl trans...

Attaching and effacing Escherichia coli is a new causal agent of diarrhea in calves. Its major virulence factors are the intimin protein, encoded by the eaeA gene, and the Shiga-like toxins, encoded by slt genes. Because the sequences of these genes are available, we selected specific primers to amplify each virulence gene so as to develop a new identification test based on multiplex amplificat...

The architectural metaphor has played an important role in many aspects of IS/ICT since the 1970s. One key influence in this has been Zachman’s ISA, first introduced in 1987. This is now a pivotal aspect of the domain, but it has developed in a lop-sided fashion with the structural features of the architectural trope effacing the cognitive ones. This paper focuses attention back on the neglec...

Transmissible murine colonic hyperplasia is characterized by proliferation of anchored stem cells in the mucosa of the descending colon of laboratory mice and is caused by Citrobacter freundii biotype 4280. This bacterium produces attaching and effacing lesions in the descending colon prior to the onset of gross hyperplasia. By mutational analysis, the chromosomal eae gene of C. freundii biotyp...
