RETRACTED: Diversity and Compatibility of Human Schistosomes and Their Intermediate Snail Hosts

Abstract

Human schistosomiasis is a major neglected tropical disease that remains endemic in numerous countries of the tropics and subtropics. Controlling the transmission of schistosomes in their intermediate snail hosts remains a key challenge in the fight against schistosomiasis. Divergence in species, biogeography, and genotype in schistosomes and their intermediate hosts has resulted in diverse parasite-host interactions. This review focuses on recent insights in the biogeography and diversity of schistosome species and their snail hosts, and the molecular basis of compatibility polymorphism between them.

“…The disease decreases both the growth and intellectual development of children and the production and working capacity of adults, affecting 200 million people in approximately 76 countries across Asia, Africa, and South America. Schistosomiasis caused by Schistosoma japonicum (S. japonicum) is widely endemic along the middle and lower reaches of the Yangtze River in China [1]. Oncomelania hupensis (O. hupensis), the only intermediate host of S. japonicum, plays a vital role in S. japonicum transmission in China.…”

Genetic Crosses and Linkage Mapping in Schistosome Parasites

“…S. mansoni shows dramatic differences in host specificity both at the intraspecific level to different snail genotypes or populations of Biomphalaria spp ., and at the interspecific level to different species of Biomphalaria [40]. Similarly, S. haematobium shows well documented variation in specificity to different Bulinus species and populations [4, 41]. Four lines of evidence demonstrate that this variation in host specificity is heritable — i.e.…”

Co-infecção Plasmodium falciparum e Schistosoma haematobium: papel dos genes HLA não-clássicos de classe I (HLA-G, -E e -F) na suscetibilidade à malária

“…Schistosomiasis is caused specifically by one of the six different species of trematode flatworms of the genus Schistosoma (Figure 1). Chronologically, the Schistosoma (S.) haematobium (Bilharz, 1852) was the first detected, followed by S. guineensis (Weinland, 1858), S. japonicum (Katsurada, 1904), S. mansoni (Sambon, 1907), S. intercalatum (Fisher, 1934), and S. mekongi (Voge, Bruckner & Bruce, 1978) (Sanogo et al 2018). In addition, other Schistosoma species can be considered such as S. malayensis (1988) found and described in Malaysia (Greer et al 1988) and S. mattheei, a zoo-parasite that infects baboon and bovid in Zambia, but can also parasite humans (Weyher et al 2010).…”
