title: The Role of the Intestinal Tract As a Source for Transmission of Nosocomial Pathogens.
abstract: The intestinal tract provides an important source for transmission of many nosocomial pathogens, including Enterococcus species, Clostridium difficile, Candida species, Enterobacteriaceae, and other gram-negative bacilli. Recent data suggest that the intestinal tracts of hospitalized patients may also be an important reservoir of Staphylococcus aureus. Although the clinical manifestations of these pathogens are diverse, a common pathogenesis is involved in their colonization of and dissemination from the intestinal tract. Of particular importance is the role that antibiotic selective pressure plays in promotion of colonization by antibiotic-resistant pathogens. Strategies to limit the spread of these pathogens must include efforts to improve adherence to standard infection control practices and promotion of good antimicrobial stewardship. New strategies that include application of novel technologies to the problem of pathogen transmission are needed, and additional research is needed to clarify the potential utility of selective decontamination of the digestive tract.
