Congenital Infection with Schistosoma japonicum but not with Schistosoma bovis in Sheep [PDF]

open access: possibleThe Journal of Parasitology, 2002
The present study investigated whether Schistosoma japonicum or Schistosoma bois could establish prenatally in lambs. Three ewes were exposed to S. japonicum by intramuscular injection of cercariae, and 3 ewes were exposed to S. bovis cercariae using the leg-emerging technique approximately 2 mo before delivery, and 1 age-matched pregnant ewe served as

Is Schistosoma mansoni Replacing Schistosoma haematobium in the Fayoum?

The American Journal of Tropical Medicine and Hygiene, 1993
Schistosoma mansoni is progressively replacing S. haematobium along the Nile River in Egypt. This change has occurred in the past 15-20 years following construction of the Aswan High Dam in the 1960s. The cause is a shift in relative abundance of the snail vectors Biomphalaria alexandrina and Bulinus truncatus.

Schistosoma mansoni and Schistosoma haematobium: Differences in development

Experimental Parasitology, 1981
Abstract Growth and maturation of the Puerto Rico strain of Schistosoma mansoni in mice and the Ghana strain of Schistosoma haematobium in hamsters were compared beginning 19 days after infection. In S. mansoni, optimum development was determined, with copulation first observed on Day 25, egg shell protein formation observed on Day 28, and ...

Immunoblot analysis of membrane antigens of Schistosoma mansoni, Schistosoma intercalatum, and Schistosoma haematobium against Schistosoma-infected patient sera

Parasitology Research, 2010
Antigens present in aqueous n-butanolic extracts (BE) of Schistosoma mansoni (Venezuelan JL strain), Schistosoma intercalatum (Cameroon EDEA strain), and Schistosoma haematobium (Yemen strain) adult worm membranes were compared in immunoblot against sera of patients infected with S. mansoni, S. intercalatum, S.

Is there Immunity to Schistosoma japonicum?

Parasitology Today, 2000
The Oriental schistosome, Schistosoma japonicum, unlike the other two major schistosomes that infect humans (S. mansoni and S. haematobium), is a zoonotic species. The transmission dynamics and the potential effects of host-related regulatory factors, including immunity, are likely to be distinct for this parasite.
