Salmonella Current Concepts

Abstract

Salmonella induces a wide spectrum of disease in cattle ranging from inapparent subclinical infections to acute fulminant bacteremia, endotoxemia, and death. The variable manifestations of disease reflect the virulence of different Salmonella serotypes and the influence of challenge dose and host immunity. Many salmonella infections reflect opportunistic infections of compromised hosts. Strategies to prevent and manage salmonella outbreaks should emphasize minimizing pathogen exposure and maximizing host immunity.
