Pesticide residues in three fishing sites in Burkina Faso.

Pesticides control pests and diseases in crops in order to enhance agricultural productivity; however, they are responsible for damaging aquatic resources. This study aimed to assess pesticide residues in aquatic ecosystems in Burkina Faso. Data were collected in two sampling sites: Bama and Banzon.

An Alarming Eastward Front of Cassava Mosaic Disease in Development in West Africa.

Begomoviruses are a major threat to cassava production in Africa. Indeed, during the 1990s, the emergence of a recombinant begomovirus (East African cassava mosaic virus-Uganda, EACMV-Ug) resulted in crop devastation and severe famine in Uganda. In 2023, during a pre-survey of cassava farms at Forécariah, South-West Guinea, 22 samples showing peculiar cassava mosaic disease (CMD) symptoms were collected, and subsequent laboratory analysis confirmed the presence of EACMV-Ug in the samples.

Evaluation of waning of IgG antibody responses after rVSVΔG-ZEBOV-GP and Ad26.ZEBOV, MVA-BN-Filo Ebola virus disease vaccines: a modelling study from the PREVAC randomized trial.

rVSVΔG-ZEBOV-GP and Ad26.ZEBOV, MVA-BN-Filo are WHO-prequalified vaccination regimens against Ebola virus disease (EVD). Challenges associated with measuring long-term clinical protection warrant the evaluation of immune response kinetics after vaccination.

Seroprevalence of Viral Hepatitis B and Occult Hepatitis B Among Blood Donors in Africa: A Systematic Review and Meta-Analysis.

Hepatitis B virus (HBV) Infection remains a public health problem and a threat to blood transfusion safety. The aim of this study was to summarise the scientific literature on the seroprevalence of HBV and occult HBV among blood donors in Africa. Searches were carried out in PubMed, Science Direct, Global Index Medicus and African Journals Online from 2012 to 2022.

An Expression Quantitative Trait Locus of Fc Gamma Receptor Genes is Associated with Anti-Malarial IgG Responses and Infection Levels in Burkinabe Families.

Background: The interaction between antibodies and Fc gamma receptors (FcγRs) plays a critical role in regulating immune responses to Plasmodium falciparum. Polymorphisms in genes encoding FcγRs influence the host's capacity to control parasite infection. This study investigates whether non-coding variants influencing FcγR expression are associated with anti-malarial immunization and infection traits.
