Interests: Nervous System Structure and Function in an Intermediate Host for Schistosomiasis

The parasitic disease schistosomiasis (also referred to as ‘snail fever’) is estimated to impact the lives of up to ten percent of the people on Earth. Due to the chronic and debilitating nature of its symptoms, schistosomiasis ranks second only to malaria in terms of the costs inflicted on the economic productivity of developing countries. One obligatory factor that is shared by all schistosome blood flukes is the presence of specific snail species that serve as intermediate hosts, supporting critical stages of their multiplication and transformation into forms that are capable of infecting humans. The class of schistosomiasis that occurs in the Western Hemisphere is caused by Schistosoma mansoni, which requires the planorbid pond snail Biomphalaria glabrata to serve as its primary intermediate host. As human infections would cease if parasite infections in snails were prevented, our investigation explores the Biomphalaria nervous system for potential interventions in this host-parasite system.

Double-label

Figure 1 – Serotonergic neurons that regulate male reproductive behavior of Biomphalaria glabrata. Neurons that project to male reproductive structures were labelled with a dye (green) prior to processing for serotonin-like immunohistochemistry (red). Double-labeled neurons (yellow) are serotonergic neurons that project to male reproductive structures.
