Intermediate snail host of Schistosoma species are known to exist and constitute public health problems in Imo state. Schistosoma mansoni, S. japonicum, and S. haematobium are trematodes whose complex life cycles require an intermediate snail host. Schistosoma intercalatum (West Africa) 4. The parasite can live in the water for only 48 hours without a mammalian host.

Adults can live from 3 - 5 yrs. Schistosoma intercalatum (rare) Life cycle: Humans are the principal hosts for the major species. The urinary tract or the intestines may be infected. Under optimal conditions in the environment, the eggs hatch and release miracidia, which swim and penetrate specific snail intermediate hosts. Adoptively transferred resistance to Schistosoma mansoni in the snail intermediate host Biomphalaria glabrata was measured as a function of miracidial challenge dose.

Hybridization experiments between S. intercalatum from Cameroon and Zaire have resulted in … Schistosoma intercalatum is largely identified in inhabitants and immigrants from western Africa. Delay, J. Jourdane Humans are infected via penetration of 2 mm schistosome cercariae through intact skin, after they are released into the water by certain freshwater snails (intermediate hosts).

Schistosoma japonicum is an important parasite and one of the major infectious agents of schistosomiasis.This parasite has a very wide host range, infecting at least 31 species of wild mammals, including 9 carnivores, 16 rodents, one primate (Human), two insectivores and three artiodactyls and therefore it can be considered a true zoonosis. Adoptively transferred resistance to Schistosoma mansoni in the snail intermediate host Biomphalaria glabrata was measured as a function of miracidial challenge dose. The Schistosoma larvae undergo the next phase of their lifecycles in these snails, spending their time reproducing and developing.
The eggs are intermediate in size between the eggs of S. haematobiumand S. bovis. Competitive exclusion in human schistosomes: the restricted distribution of Schistosoma intercalatum - Volume 113 Issue 2 - L. A. Tchuem Tchuenté, S. Morand, D. Imbert-Establet, B.
