Spontaneous worm expulsion and intestinal IgA response in mice infected by Vampirolepis nana.

The expulsion of the gastrointestinal parasite Vampirolepis nana was examined in different mouse strains and in immunosuppressed mice infected to different degrees with eggs and cysticercoids. To investigate the immunological mechanism that regulates expulsion, surface-bound mouse immunoglobulins were examined on adult worms. The time to spontaneous expulsion of worms was dependent on strain (C57BL, BDF(1), B6C3F(1) View Article and Find Full Text PDF
