C4-Dicarboxylic acid cycle and Salmonella typhi.
Several papers have already been published for answering the question whether or not the tricarboxylic acid cycle or the C4-dicarboxylic acid cycle plays a role in microorganisms, and a summarizing description of the subject is seen in Ajl's article(1). Karlson and Barker(2), for example, stated that the tricarboxylic acid cycle does not operate in Azotobacter agilis, Barron, Ardao and Hearon (...
متن کاملSalmonella 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...

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...
متن کاملAcid exposure induces multiplication of Salmonella enterica serovar Typhi.
Salmonella enterica serovar Typhi faces several environmental stresses while going through the stomach (acidic pH) to the small intestine (basic pH) and intracellularly in macrophages (acidic pH) in humans. The acidic pH followed by alkaline pH in the small intestine might be responsible for expression of certain stress-induced genes, resulting in not only better survival but also induction of ...
