Vi I typing phage for generalized transduction of Salmonella typhi.
Salmonella typhi Vi typing phages were used to transduce temperature-sensitive (Ts) mutants of Salmonella typhi. Antibiotic resistance and Ts+ markers were transduced at high frequency (> 10(-4) per virulent phage). Several markers were cotransduced by phage Vi I, suggesting that it may be useful for mapping studies of the S. typhi genome.
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 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...

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...
