BACKGROUND Enterococcus faecalis is an opportunistic pathogen that causes most of the enterococcal infections. Among the different factors implicated in the pathogenesis of these organisms, biofilm formation and antibiotic resistance are the most important. The ability for biofilm formation has been attributed to the presence of some virulence genes. However, no definite correlation has been fo...

Assessing learners' needs is an integral part of any curriculum and course design , namely English for specific purposes (ESP), syllabus design, materials development, teaching methods and testing issues. Critical approach to needs analysis, which is a relatively recent approach, acknowledges the rights of different stakeholders including teachers, students and administrators in the process of ...

humanism and socio-constructivism have entailed drastic developments in education including that of foreign/second language. incorporating teachers and learners in all areas of education including materials development and evaluation, focusing four-pairs of binoculars on evaluating efl materials can be taken amongst the outcomes of this trend.  this study is a report of an evaluation of the esp...

Clostridium ultunense strain Esp belongs to the functional group of syntrophic acetate-oxidizing bacteria (SAOB), which have been identified as key organisms for efficient biogas production from protein-rich materials. Genome analysis and comparative genomics might aid us to define physiological features that are essential for maintaining this particular syntrophic lifestyle.

The enterococcal surface protein Esp, specifically linked to nosocomial Enterococcus faecium, is involved in biofilm formation. To assess the role of Esp in endocarditis, a biofilm-associated infection, an Esp-expressing E. faecium strain (E1162) or its Esp-deficient mutant (E1162Δesp) were inoculated through a catheter into the left ventricle of rats. After 24 h, less E1162Δesp than E1162 were...
