Infection-immunity in Experimental Salmonellosis
Salmonella enteritidis is highly virulent for the mouse causing an infection resembling mouse typhoid. Survivors of the infection are completely resistant to reinfection and eliminate a large challenge dose of virulent organisms within 72 hr. The antigenically related Salmonella gallinarum was almost avirulent for the mouse but animals vaccinated with this organism were equally capable of elimi...
متن کاملRole of neutrophils in murine salmonellosis.
Gastrointestinal infections with Salmonella enterica serovars have different clinical outcomes that range from localized inflammation to a life-threatening systemic disease in the case of typhoid fever. Using a mouse model of systemic salmonellosis, we investigated the contribution of neutrophils to the innate immune defense against Salmonella after oral infection. Neutrophil infiltration was d...
متن کاملMechanism of protective immunity induced by porin-lipopolysaccharide against murine salmonellosis.
Investigations were undertaken to characterize the protective immunity induced by porin-lipopolysaccharide (LPS) against Salmonella typhimurium infection in mice. Mice immunized with porin-LPS showed higher levels of antiporin immunoglobulin G than mice which received porin alone. Further, T cells from porin-LPS-immunized mice showed an augmented proliferative response to porin in vitro compare...
متن کاملEarly events in the pathogenesis of avian salmonellosis.
Salmonellae are gastrointestinal pathogens of man and animals. However, strains that are host-specific avian pathogens are often avirulent in mammals, and those which are nonspecific are commensal in poultry. The objective of this study was to determine whether host specificity was exhibited by bacterial abilities to invade epithelial cells or resist leukocyte killing. In this study, leukocytes...
متن کاملPersistent Salmonellosis Causes Pancreatitis in a Murine Model of Infection
Pancreatitis, a known risk factor for the development of pancreatic ductal adenocarcinoma, is a serious, widespread medical condition usually caused by alcohol abuse or gallstone-mediated ductal obstruction. However, many cases of pancreatitis are of an unknown etiology. Pancreatitis has been linked to bacterial infection, but causality has yet to be established. Here, we found that persistent ...
