Immune mechanism of rats to nippostrongylus brasiliensis in vitro part 1 the influence of humoral and secretory antibodies and mast cells


, : Immune mechanism of rats to nippostrongylus brasiliensis in vitro part 1 the influence of humoral and secretory antibodies and mast cells. Zeitschrift fuer Parasitenkunde 50(1): 57-66

The influence of humoral and secretory antibodies as well as various cell supplements on N. brasiliensis was tested in vitro. Adult Spraque-Dawley rats approximately 12 wk of age were used. Various tests were conducted with the addition of serum or secretory antibodies of repeatedly infected and immune rats to the medium. In these tests, there was no difference in growth or mortality rate exhibited between larval or adult N. brasiliensis. This is in contrast to cultures where serum and secretory antibodies of non-infected animals were used. A 100% degranulation of mast cells from infected rats occurred within 14-22 h in cultures of adult N. brasiliensis. Variations were not noticed in viability of N. brasiliensis kept in media for 10 days with or without cell supplements, or with or without sera of infected or non-infected rats. There was no variation in the development of, or a higher mortality rate in the larval stages and adult Nippostrongylus in media containing sera and secretory antibodies of infected or non-infected rats.
