The phylogeography and incidence of multi-drug resistant typhoid fever in sub-Saharan Africa

Open access

Abstract

There is paucity of data regarding the geographical distribution, incidence, and phylogenetics of multi-drug resistant (MDR) Salmonella Typhi in sub-Saharan Africa. Here we present a phylogenetic reconstruction of whole genome sequenced 249 contemporaneous S. Typhi isolated between 2008-2015 in 11 sub-Saharan African countries, in context of the 2,057 global S. Typhi genomic framework. Despite the broad genetic diversity, the majority of organisms (225/249; 90%) belong to only three genotypes, 4.3.1 (H58) (99/249; 40%), 3.1.1 (97/249; 39%), and 2.3.2 (29/249; 12%). Genotypes 4.3.1 and 3.1.1 are confined within East and West Africa, respectively. MDR phenotype is found in over 50% of organisms restricted within these dominant genotypes. High incidences of MDR S. Typhi are calculated in locations with a high burden of typhoid, specifically in children aged <15 years. Antimicrobial stewardship, MDR surveillance, and the introduction of typhoid conjugate vaccines will be critical for the control of MDR typhoid in Africa.

  • In the past two decades, multidrug-resistant Salmonella Typhi has emerged and spread throughout the sub-Saharan Africa region.

    “in the past two decades, multidrug-resistant (defined as resistance to ampicillin, trimethoprim-sulfamethoxazole, and chloramphenicol) S. Typhi has emerged and spread throughout the region.”

    From Antimicrobial Resistance Rates and Surveillance in Sub-Saharan Africa: Where Are We Now? (2022) · cites this paper as [68]

    The Discussion (page unavailable) reports that MDR S. Typhi can arise locally and spread through population movements in East and West Africa. The Results (page unavailable) use the stated three-drug definition, but identify MDR isolates in only four of the eleven sampled countries. The paper does not establish spread throughout sub-Saharan Africa over the claimed two-decade period. (LLM, conf=0.87)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
