Salmonella pathogenicity island 7 (SPI-7) in Salmonella enterica serovar Typhi appears to be related to other genomic islands. Evidence suggests that SPI-7 is susceptible to spontaneous circularization, loss, and transposition. Here, we demonstrate that a region within SPI-7 has the ability to mobilize the small incQ plasmid R300B.
The cystic fibrosis transmembrane conductance regulator (CFTR) protein is an epithelial receptor mediating the translocation of Salmonella enterica serovar Typhi to the gastric submucosa. Since the level of cell surface CFTR is directly related to the efficiency of serovar Typhi translocation, the goal of this study was to measure CFTR expression by the intestinal epithelium during infection. C...
The past decade has seen remarkable progress in our understanding of the scale global typhoid fever problem,1 alarming emergence south Asia extensively drug-resistant Salmonella enterica serovar Typhi (S Typhi) threatening effective treatment,2 and WHO prequalification a conjugate vaccine,3 new tool to prevent disease. In Lancet, Firdausi Qadri colleagues report analysis 18 months follow-up clu...
Typhoid caused by Salmonella enterica serovar Typhi remains a major health concern worldwide. The emergence of multidrug-resistant strains of Salmonella with increased virulence, communicability, and survivability leading to increased morbidity and mortality has further complicated its management. Currently available vaccines for typhoid have less-than-desired efficacy and certain unacceptable ...
Host-adapted strains of Salmonella enterica cause systemic infections and have the ability to persist systemically for long periods of time and pose significant public-health problems. Multidrug-resistant S. enterica serovar Typhi (S. Typhi) and nontyphoidal Salmonella (NTS) are on the increase and are often associated with HIV infection. Chronically infected hosts are often asymptomatic and tr...
Unlike broad-host Salmonella serovars, which cause self-limiting disease, Salmonella enterica serovar Typhi can infect only humans causing typhoid fever, a life-threatening systemic disease. The molecular bases for these differences are presently unknown. Here we show that the GTPase Rab29 (Rab7L1) distinguishes the intracellular vacuole of human-adapted and broad-host Salmonella serovars. A sc...
Infections with Salmonella enterica serovar Typhi isolates that are multidrug resistant (MDR: resistant to chloramphenicol, ampicillin, trimethoprim-sulphamethoxazole) with intermediate ciprofloxacin susceptibility are widespread in Asia but there is little information from Cambodia. We studied invasive salmonellosis in children at a paediatric hospital in Siem Reap, Cambodia. Between 2007 and ...
Bacterial live-vector vaccines aim to deliver foreign antigens to the immune system and induce protective immune responses, and surface-expressed or secreted antigens are generally more immunogenic than cytoplasmic constructs. We hypothesize that an optimum expression system will use an endogenous export system to avoid the need for large amounts of heterologous DNA encoding additional proteins...
Salmonella enterica serovar Typhi (S. Typhi) is one of the typhoidal Salmonellae that causes typhoid fever. We report first case an XDR S. in a suspected Endocarditis with Aortic Valve Replacement and deranged INR. The identification was carried out by automated system. antibiogram performed according to CLSI recommendations. isolates were found resistant Azithromycin. Although has been reporte...
