Bacterial infections of the gut (excluding enteric fever).

Bacterial enteric infections are still a major cause of morbidity and mortality, and many challenges lie ahead in understanding and managing these conditions. Clostridium difficile remains the most important nosocomial infection. Antibiotic resistance makes the treatment of shigella infections increasingly difficult. Molecular and cellular techniques are, however, rapidly expanding our understanding of the complexity of the pathogenesis of established and newly recognized pathogens.
