A short-oligonucleotide microarray that allows improved detection of gastrointestinal tract microbial communities.

Background: The human gastrointestinal (GI) tract contains a diverse collection of bacteria, most of which are unculturable by conventional microbiological methods. Increasingly molecular profiling techniques are being employed to examine this complex microbial community. The purpose of this study was to develop a microarray technique based on 16S ribosomal gene sequences for rapidly monitoring the microbial population of the GI tract.

A variant enterococcal surface protein Esp(fm) in Enterococcus faecium; distribution among food, commensal, medical, and environmental isolates.

Enterococci are increasingly important causes of nosocomial disease. Also, they are associated with food and have a history of use as dairy starter and probiotic cultures. An enterococcal surface protein Esp(fs) is involved the virulence and biofilm-forming capacity of Enterococcus faecalis and recently we demonstrated the presence of a homologue Esp(fm) in E.
