  • Title: Nematospiroides dubius: stimulation of acquired immunity in inbred strains of mice.
    Author: Behnke JM, Wakelin D.
    Journal: J Helminthol; 1977 Sep; 51(3):167-76. PubMed ID: 599263.
    Abstract:
    The development of immunity to Nematospiroides dubius was studied in three strains of inbred mice (BALB/c, C3H and NIH). Although a primary infection in NIH mice persisted for two months without evidence of a reduction in worm numbers, female mice of this strain readily developed resistance to reinfection. The degree of resistance was enhanced when an immunizing infection of 600 larvae was administered as 6 separate doses of 100 larvae given between days 0 and 11, and the worms removed by anthelmintic treatment given on days 15, 21, 28 and 35. Immunity in mice immunized in this way was manifest both as a reduction in worm recoveries on days 9-14 after challenge and also as an expulsion of established worms from the intestine. BALB/c mice were initially less resistant, but expelled most of the worms which became established; C3H mice showed no evidence of expulsion. The finding that inbred NIH and BALB/c mice acquire resistance to N. dubius offers possibilites for the systematic analysis of lymphoid cell activity in initiating and expressing immunity to this parasite.
