Article Synopsis
  • - This study investigates the gut microbiota of the blackfly Simulium damnosum s.l. to understand its role in the transmission of the parasite Onchocerca volvulus, which causes river blindness.
  • - Adult female blackflies were collected from various regions in Cameroon, and their gut microbiota was analyzed using advanced sequencing techniques to identify dominant bacterial taxa and assess microbiota diversity.
  • - Findings revealed significant variations in the gut microbiota related to certain factors like the blackfly's reproductive status and geographic origin, with specific bacteria associated with the absence of O. volvulus infection, indicating a complex relationship between the microbiota and parasite transmission.

Vector control using larvicides is the main alternative strategy to address limits of preventive chemotherapy using ivermectin for the control of onchocerciasis. However, it remains substantially limited by implementation difficulties, ecological concerns and the resistance of vector populations. Therefore, efficient and environmentally safe alternative control strategies are still needed.

Next generation sequencing technologies enabled high-density genotyping for large numbers of samples. Nowadays SNP calling pipelines produce up to millions of such markers, but which need to be filtered in various ways according to the type of analyses. One of the main challenges still lies in the management of an increasing volume of genotyping files that are difficult to handle for many applications.

The purpose of this study was to investigate factors involved in vector competence by analyzing whether the diversity and relative abundance of the different bacterial genera inhabiting the fly's gut could be associated with its trypanosome infection status. This was investigated on 160 randomly selected G. p.
