Individuals with acute malaria infection generated high levels of antibodies that cross-react with the SARS-CoV-2 Spike protein. Cross-reactive antibodies specifically recognized the sialic acid moiety on N-linked glycans of the Spike protein and do not neutralize in vitro SARS-CoV-2. Sero-surveillance is critical for monitoring and projecting disease burden and risk during the pandemic; however, routine use of Spike protein-based assays may overestimate SARS-CoV-2 exposure and population-level immunity in malaria-endemic countries.

Malaria infections occurring below the limit of detection of standard diagnostics are common in all endemic settings. However, key questions remain surrounding their contribution to sustaining transmission and whether they need to be detected and targeted to achieve malaria elimination. In this study we analyse a range of malaria datasets to quantify the density, detectability, course of infection and infectiousness of subpatent infections. Asymptomatically infected individuals have lower parasite densities on average in low transmission...

Data from: Generational conservation of composition and diversity of field-acquired midgut microbiota in Anopheles gambiae sensu lato during colonization in the laboratory

Jewelna Akorli, Philomena A. Namaali, Godwin W. Ametsi, Richardson K. Egyirifa & Nana Adjoa P. Pels
The gut microbiota is known to play a role in the mosquito vectors’ life history, which is a subject of increasing research. Laboratory experiments are essential for such studies and require laboratory colonies. In this study, the conservation of field-obtained midgut microbiota was evaluated in laboratory-reared Anopheles gambiae s.l. mosquitoes continuously hatched in water from the field breeding habitats. Pupae and late instars were obtained from the field and reared, and the emerged adults were...
