a study of insect digestive enzymes makes sense given that the gut is the major interface between the insect and its environment. an understanding of gut and digestive enzyme function is essential when advanced methods of insect management such as application of enzyme inhibitors and transgenic plants are developed to control insect pests. the aim of the current research project was to study mi...

BACKGROUND Virginiamycin use in poultry selects for Enterococcus faecium with cross-resistance to quinupristin-dalfopristin, a drug for vancomycin-resistant E. faecium in humans. We conducted an epidemiologic study of poultry exposures as risk factors for human carriage of quinupristin-dalfopristin-resistant E. faecium. METHODS Rectal or fecal samples for E. faecium testing were obtained from...
