OBJECTIVES To investigate the association between the presence of a genetic island inserted within the sapABCDF operon of Salmonella Typhi and the susceptibility to antimicrobial peptides. METHODS Genetics and bioinformatics approaches were used to study the genomic organization of the sap operon of Salmonella Typhi and several serovars of Salmonella enterica. PCR was used to confirm the info...

Background and Objective: Salmonella typhi infection occurs in most endemic areas. Patients suspected of typhoid fever located in the Badda and Shantinagar localities of Dhaka were the studied population. A total of 107 blood specimens were collected. This study attempted to determine the antibiotic susceptibility pattern of Salmonella typhi among different age and gender groups having clinica...

the role of vi-capsular polysaccharide (vi-cps) in human immunity against infection caused by salmonella typhi is well known. the downstream process of purification generally causes depolymerization of vi-cps to a nonimmunogenic low molecular weight form. in the present study, a standard strain of sal. typhi ty6s was grown under submerge cultural conditions in a pilot-plant scale of 90 liter fe...
