Molecular Tools and Schistosomiasis Transmission Elimination

Area of Science:

• * Schistosomiasis transmission dynamics and control strategies.

Background:

• * Large-scale schistosomiasis control in sub-Saharan Africa risks incomplete eradication, leading to persistent transmission.
• * Understanding snail infection prevalence and environmental factors is crucial for effective intervention.

Purpose of the Study:

• * To evaluate loop-mediated isothermal amplification (LIA) for large-scale screening of snail infection prevalence.
• * To investigate the impact of habitat biota on snail host capacity and transmission.
• * To identify snail feeding preferences and attractive vegetation for targeted molluscicide application.

Main Methods:

• * Large-scale screening of snail infection prevalence using loop-mediated isothermal amplification (LIA).
• * Next-generation sequencing (NGS) to analyze snail gut contents and identify feeding preferences.
• * Assessment of environmental biota in snail habitats and their influence on host capacity.

Main Results:

• * LIA enables accurate determination of man-to-snail transmission.
• * Snail feeding preferences and habitat vegetation identified in transmission hotspots and non-hotspots.
• * Environmental biota effects on snail host capacity elucidated.

Conclusions:

• * LIA is a valuable tool for monitoring schistosomiasis transmission.
• * Understanding snail ecology and feeding habits is essential for optimizing control efforts.
• * Targeted mollusciciding strategies can be enhanced by identifying attractive vegetation.
