The tom element, putatively associated with optic morphology (Om) mutations in Drosophila ananassae, was identified as a retrovirus-like transposable element. The tom element was found to terminate with 475 (or 474) base pair direct repeats which are identical in sequence to each other. Southern blot and heteroduplex analyses showed the tom element to have(More)
The involvement of haematopoietic and lymphopoietic cells in the expulsion of Trichinella spiralis from the intestine of mice, and the origin of the subepithelial mast cells (SMCs) and the globule leucocytes (GLs) were determined using SMC- and GL-deficient WBB6F1-W/Wv and WCB6F1-S1/S1d mice. On day 12 after infection with T. spiralis, SMCs and GLs appeared(More)
Eosinophil infiltrations were observed in the intestine and the muscle of both Trichinella spiralis-infected (WBxC57BL/6)F1-W/Wv mice and their littermates, WBB6F1-+/+, +/W, +/Wv, almost to the same extent. W/Wv mice did not show infiltration of subepithelial mast cells and globule leucocytes in response to T. spiralis infection. Increased numbers of these(More)
