Salmonella Typhi and Salmonella Paratyphi A elaborate distinct systemic metabolite signatures during enteric fever

The host-pathogen interactions induced by Salmonella Typhi and Salmonella Paratyphi A during enteric fever are poorly understood. This knowledge gap, and the human restricted nature of these bacteria, limit our understanding of the disease and impede the development of new diagnostic approaches. To investigate metabolite signals associated with enteric fever we performed two dimensional gas chr...

in Salmonella typhi

S.typhi ompSI constitutes a novel porùt gene. It has seven putative OmpR-binrling boxes and three promoters. Our current model for expression contempLates activation of transcription, from Pl, by OmpR-bindùtg to boxes II anct III (Ctype, low affinity); whereas boxes I and IV-VII would be ùwolved in negative regulation. The fact that ompSI expression increases more thayt 100-foçt upon removal of...

Trends in Salmonella enteric serovar Typhi in Nairobi, Kenya from 2004 to 2006.

BACKGROUND Typhoid fever is a global health problem. The World Health Organization (WHO) estimates that the current annual global burden of typhoid is approximately 22 million new cases, 5% of which are fatal. METHODOLOGY To assess the trends in antibiotic resistance in 100 Salmonella enterica serovar Typhi strains were isolated from the blood of patients in Nairobi, Kenya, from 2004 to 2006....

Salmonella typhi and other salmonellas

There is almost a north-south divide between the geographical prevalence of the two broad clinical syndromes caused by the organisms of the genus salmonella. The prolonged bacteraemic illnesses of typhoid and paratyphoid fevers, caused by the exclusively human pathogens, Salmonella typhi and paratyphi A, B, and C, are endemic only in the economically disadvantaged countries where poor sanitatio...
