Resistance of Biomphalaria alexandrina to Schistosoma mansoni and Bulinus truncatus to Schistosoma haematobium Correlates with Unsaturated Fatty Acid Levels in the Snail Soft Tissue

Autor: Marian Elias, Rasha S. Hanafi, Samia El-Bardicy, Ebtisam A. Hafez, Rashika El Ridi

Publikováno v: Journal of Parasitology Research, Vol 2020 (2020)

Only a fraction of the Biomphalaria and Bulinus snail community shows patent infection with schistosomes despite continuous exposure to the parasite, indicating that a substantial proportion of snails may resist infection. Accordingly, exterminating
