Background: The emergence and spread of Extended-Spectrum Beta-Lactamase (ESBL)-producing Escherichia coli pose significant challenges for treatment of infections globally. This challenge is exacerbated in sub-Saharan African countries, where the prevalence of ESBL-producing E. coli is high.

Background: Distinguishing Plasmodium falciparum recrudescence from new infections is crucial for the assessment of antimalarial drug efficacy against P falciparum. We aimed to compare the efficacy of different genotyping methods to assess their effect on drug efficacy estimates, particularly in patients from high-transmission settings with polyclonal infections.

Methods: In this head-to-head comparison study, we compared five different genotyping methods currently used: fast capillary electrophoresis (F-CE) using msp1, msp2, and glurp; high-resolution capillary electrophoresis (H-CE) using msp1, msp2, and glurp; H-CE using microsatellites; targeted amplicon deep sequencing (TADS) using single nucleotide polymorphism (SNP)-rich markers; and high-resolution melting (HRM) analysis using msp1 and msp2.

Background: The emergence of drug-resistant clones of Plasmodium falciparum is a major public health concern, and the ability to detect and track the spread of these clones is crucial for effective malaria control and treatment. However, in endemic settings, malaria infected people often carry multiple P. falciparum clones simultaneously making it likely to miss drug-resistant clones using traditional molecular typing methods.

Malaria surveillance is hampered by the widespread use of diagnostic tests with low sensitivity. Adequate molecular malaria diagnostics are often only available in centralized laboratories. PlasmoPod is a novel cartridge-based nucleic acid amplification test for rapid, sensitive, and quantitative detection of malaria parasites.
