Cotton rats infected by infective third-stage larvae of Litomosoides carinii were treated at increasing time intervals by a threefold injection of living homologous microfilariae (mf) during the prepatent period. Starting with the first treatment 3, 4 or 5 weeks p.i. seven animals remained completely and two almost mf-negative (1 or 2 mf/mm3 each only once) until 16 weeks p.i. Starting 6, 7 or 8 weeks p.i. six animals developed a normal level of parasitaemia between 42 and 436 mf/mm3, two animals developed a continuous level of 1-2 mf/mm3. The number of fertile adult worms shedding great numbers of microfilariae in the pleural cavity was equal in all animals. However, in mf-negative animals the lung capillary blood showed, in the geometric mean, only 0.6% of the mf-concentration seen in mf-positive animals. The hypothesis is proposed that microfilariae accumulating primarily in the lung capillaries absorb all aggressive components specifically reacting with microfilarial antigens, i.e. neutralize the immune response against them to enable the development of the parasitaemia in the peripheral blood.
