Emerging gram-negative enteric infections.

This is an overview describing the microbiology, epidemiology, clinical presentations, laboratory diagnosis, and treatment of emerging gram-negative enteric infections. This review illustrates the shifts in epidemiology of infections caused by new and reemerging bacteria and highlights the role of the clinical microbiology laboratory in detecting these pathogens. It concludes with suggestions for the implementation of molecular techniques to ensure rapid surveillance and enhanced patient care.
