The human burden of environmentally transmitted infectious diseases can depend strongly on ecological factors, including the presence or absence of natural enemies. The marbled crayfish (Procambarus virginalis) is a novel invasive species that can tolerate a wide range of ecological conditions and colonize diverse habitats. Marbled crayfish first appeared in Madagascar in 2005 and quickly spread across the country, overlapping with the distribution of freshwater snails that serve as the intermediate host of schistosomiasis-a parasitic disease of poverty with human prevalence ranging up to 94% in Madagascar.

The World Health Organization (WHO) recommends periodic assessment of the therapeutic efficacy of praziquantel (PZQ) to detect reduced efficacy that may arise from drug resistance in schistosomes. In this multi-country study (2014), we assessed the therapeutic efficacy of a single oral dose of PZQ (40 mg/kg) against Schistosoma mansoni (Brazil, Cameroon, Ethiopia, Mali, Madagascar and Tanzania), S. haematobium (Cameroon, Ethiopia, Mali, Tanzania and Zanzibar) and S.

- The increasing recognition of ecosystems' importance for human well-being highlights the need for effective mapping and assessment of ecosystem services (ES), which provide various benefits from nature to people.
- A new rapid spatial assessment framework was developed to efficiently identify sites offering multiple ES, which was applied in Madagascar to inform conservation investments in biodiversity priority areas.
- Although the approach has limitations, such as reliance on proximity-based indicators, it can serve as a valuable tool for conservation planning and investment in regions lacking comprehensive data.
Background: Schistosomiasis affects more than 800 million people, mostly in sub-Saharan Africa. A baseline sentinel site study was conducted in the Western half of Madagascar to determine the prevalence and intensity of schistosomiasis and soil-transmitted helminth (STH) infections prior to mass drug administration, and to explore the associations between infection and school attendance, and access to water, sanitation and hygiene (WASH) facilities.
Methods: A three-stage, cluster-randomised cross-sectional study was conducted in 29 sentinel sites in October 2015.
Of the four species of Bulinus found on Madagascar, three species: B. obtusispira, B. liratus and B.
