I am not aware of somebody who works on the immunity of the parasite
itself, but there is a weak indication that schistosmes might possess
cytotoxic peptides which could be active against microorganisms.
K. Hancock et al. (J. Parasitol 1997, Aug; 83(4): 612-618) described an
antigen which is useful for the detection of S. mansoni and S. haematobium
It turns out out that this molecule has homology to the family of
saposin-like proteins, an evolutionary conserved class of cytotoxic
peptides which belong to the innate immune system (Tschopp and Hofmann
Trends Microbiol. 1996, March vol 4(3) :91-94)
Hope this helps a little bit,
