Evaluation of a point-of-care immunochromatographic assay for enteric fever in Dhaka, Bangladesh: a prospective diagnostic accuracy study.

Background: There is a shortage of rapid, accurate, and low-cost assays for diagnosing enteric fever. The dual-path platform for typhoid (DPPT) assay had high accuracy in retrospective studies with banked plasma samples. We aimed to evaluate the diagnostic accuracy of the DPPT assay in a prospective study using fingerstick capillary blood.

Genome sequences of bacteriophages that infect Typhi from Bangladesh.

This report presents near-complete genome sequences of 14 bacteriophages that infect Typhi, identified through environmental surveillance in Bangladesh between August 2021 and June 2022. The bacteriophages, belonging to the genera , , and , exhibit high degrees of sequence similarity and conserved genetic features with previously reported Typhi bacteriophages.

Old tools, new applications: Use of environmental bacteriophages for typhoid surveillance and evaluating vaccine impact.

Typhoid-conjugate vaccines (TCVs) provide an opportunity to reduce the burden of typhoid fever, caused by Salmonella Typhi, in endemic areas. As policymakers design vaccination strategies, accurate and high-resolution data on disease burden is crucial. However, traditional blood culture-based surveillance is resource-extensive, prohibiting its large-scale and sustainable implementation.
