Trends in antimicrobial resistance amongst Salmonella Paratyphi A isolates in Bangladesh: 1999-2021. [PDF]

PLoS Negl Trop Dis, 2023
Background Typhoid and paratyphoid remain common bloodstream infections in areas with suboptimal water and sanitation infrastructure. Paratyphoid, caused by Salmonella Paratyphi A, is less prevalent than typhoid and its antimicrobial resistance (AMR ...

Paratype: a genotyping tool for Salmonella Paratyphi A reveals its global genomic diversity. [PDF]

Nat Commun, 2022
Salmonella Paratyphi A, the primary etiology of paratyphoid, is estimated to cause 3.4 million infections annually, worldwide. With rising antimicrobial resistance and no licensed vaccines, genomic surveillance is key to track and monitor transmission ...

The genomic characterization of Salmonella Paratyphi A from an outbreak of enteric fever in Vadodara, India. [PDF]

Microb Genom, 2023
Salmonella enterica Typhi (S. Typhi) and Paratyphi A (S. Paratyphi A) are the causative agents of enteric fever, a systemic human disease with a burden of 300 000 cases per year in India. The majority of enteric fever cases are associated with S.

Evaluation of Antimicrobial Susceptibility Profile in Salmonella Typhi and Salmonella Paratyphi A: Presenting the Current Scenario in India and Strategy for Future Management. [PDF]

J Infect Dis, 2021
Background Systematic studies to estimate the disease burden of typhoid and paratyphoid in India are limited. Therefore, a multicenter study on the Surveillance of Enteric Fever in India was carried out to estimate the incidence, clinical presentation ...

Intracellular Salmonella Paratyphi A is motile and differs in the expression of flagella-chemotaxis, SPI-1 and carbon utilization pathways in comparison to intracellular S. Typhimurium. [PDF]

PLoS Pathog, 2022
Although Salmonella Typhimurium (STM) and Salmonella Paratyphi A (SPA) belong to the same phylogenetic species, share large portion of their genome and express many common virulence factors, they differ vastly in their host specificity, the immune ...

The Vi antigen ofSalmonella paratyphi A [PDF]

Epidemiology and Infection, 1952
1.Salmonella paratyphi Apossesses a specific Vi antigen essentially similar to that of the Vi antigen ofSalm. typhi.2. O-insensitive strains ofSalm. paratyphi Acontain more Vi antigen, and are more virulent for mice, than O-sensitive strains.3. The most suitable strains for the preparation of paratyphoid-Avaccine are those that develop both the Vi and ...

Very long O-antigen chains of Salmonella Paratyphi A inhibit inflammasome activation and pyroptotic cell death. [PDF]

Cell Microbiol, 2021
Salmonella Paratyphi A (SPtA) remains one of the leading causes of enteric (typhoid) fever. Yet, despite the recent increased rate of isolation from patients in Asia, our understanding of its pathogenesis is incomplete.
