EFFECT OF SALMONELLA TYPHOSA ENDOTOXIN ON RENAL FUNCTION, AND THE RELATIONSHIP OF FUNCTION TO RENAL HEMODYNAMICS

BACKGROUND The emergence of antibiotic-resistant strains of Salmonella enterica serovar Typhi (S. Typhi), the etiologic agent of typhoid fever, has aggravated an already important public health problem and added new urgency to the development of more effective typhoid vaccines. To this end it is critical to better understand the induction of immunity to S. Typhi. CD8(+) T cells are likely to pl...

Mice pretreated intraperitoneally with trehalose-6,6'-dimycolate (cord factor) were protected against an intraperitoneal challenge with Salmonella typhi strain Ty2 or Salmonella typhimurium strain SR 11. The nonspecific resistance to S. typhi and S. typhimurium was still detectable 7 and 14 days, respectively, after administration of cord factor. The effect of cord factor was local. Synthetic a...

Unlike the majority of Salmonella enterica serovars, Salmonella Typhi (S. Typhi), the etiological agent of human typhoid, is monophasic. S. Typhi normally harbours only the phase 1 flagellin gene (fliC), which encodes the H:d antigen. However, some S. Typhi strains found in Indonesia express an additional flagellin antigen termed H:z66. Molecular analysis of H:z66þ S. Typhi revealed that the H:...

Salmonella Typhi (S. Typhi) causes typhoid fever which is a disease characterised by high mortality and morbidity worldwide. In order to curtail the transmission of this highly infectious disease, identification of new markers that can detect the pathogen is needed for development of sensitive and specific diagnostic tests. In this study, genomic comparison of S. Typhi with other enteric pathog...

Salmonella enterica serovar Typhi (Typhi), the aetiologic agent of typhoid fever, is a human restricted pathogen. Elucidation of the interactions between the infected host and this pathogen is critical to understand infectious diseases but is deterred by a lack of in vivo infection assays, since Typhi uniquely infects humans and there is no suitable animal model. Macrophages can be used as an a...

This study characterized a cephalosporin-resistant Salmonella enterica serovar Typhi isolate. The organism possessed a plasmid encoding the CTX-M-15 extended-spectrum-beta-lactamase. This plasmid is the determinant for the phenotype of cephalosporin resistance and is transferrable among Enterobacteriaceae.

BACKGROUND Enteric fever is endemic in all parts of India. The Widal agglutination test is widely used for its diagnosis. But the interpretation of Widal test depends upon the baseline titre which is prevalent amongst healthy individuals in a particular geographical area. AIM Present study was undertaken to establish the normal baseline titre in apparently healthy blood donors and also to det...
