Comparative genomics of Salmonella enterica serovar Typhi strains Ty2 and CT18.
We present the 4.8-Mb complete genome sequence of Salmonella enterica serovar Typhi strain Ty2, a human-specific pathogen causing typhoid fever. A comparison with the genome sequence of recently isolated S. enterica serovar Typhi strain CT18 showed that 29 of the 4,646 predicted genes in Ty2 are unique to this strain, while 84 genes are unique to CT18. Both genomes contain more than 200 pseudog...
متن کاملHeterologous expression of Escherichia coli porin genes in Salmonella typhi Ty2: regulation by medium osmolarity, temperature and oxygen availability.
Electrophoretic analysis of outer membrane proteins showed that Salmonella typhi OmpC expression is not reciprocally regulated relative to OmpF as described for Escherichia coli and S. typhimurium. When bacteria were grown in minimal media, both OmpC and OmpF were repressed as the osmolarity increased. However, in Luria broth, expression of OmpC was slightly induced by osmolarity up to 0.3 osmM...
متن کاملImmunoprotectivity of Salmonella enterica serovar Enteritidis virulence protein, InvH, against Salmonella typhi
Objective(s):Typhoid fever is a dreadful disease of a major threat to public health in developing countries. Vaccination with bacterial immunodominant components such as surface proteins may prove as a potent alternative to live attenuated vaccines. InvH, an important part of needle complex in type three secretion system (TTSS) plays important role in efficient bacterial adherence and entry int...
متن کاملin 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...
متن کاملPolysaccharide Antigen of Salmonella typhi
Classical identification of S. typhi involves culture on primary agar plates and requires another 24 hours for biochemical testing. The colonies suspected to be Salmonellae will be further tested with their speci fic antisera. Most isolates of Sal monella from natural sources can be classified serologically into five groups, A to E, by a combination of multiple o (somatic), H (flagella) and V...
