Penetration Enzymes of Schistosome Cercariae.
Abstract
Cercarial penetration enzymes presented during percutaneous infection were antigenic but not protective. Sustained high cercarial production requires critical conditions of snail health and exposure age; exposure level; light and temperature. Saprophytic colonization of Biomphalaria glabrata immobilizes cercariae thus reducing cercarial output and infectivity. Schistosomules produced artificially are similar to those developing after skin penetration as assayed ultrastructurally and biologically. (Author)
