Abstract

The effect of peritoneal macrophages and serum from mice infected with Babesia microti, Schistosoma mansoni and B. microti plus S. mansoni on the growth of B. microti was assessed in short term in vitro cultures using the criterium of rate of incorporation of (3H)Hypoxan-thine. In the absence of serum, macrophages and supernatants from macrophage cultures failed to affect the in vitro growth of B. microti. In contrast, in the absen-de of macrophages, serum from mice infected with B. microti and with B. microti plus S. mansoni induced a marked inhibition of the in vitro growth of B. Microti. The level of inhibition induced by serum from mice infected with both S. mansoni and B. microti exceeded consistently that induced by serum from mice infected with B. microti only. Serum from mice only infected with S. mansoni induced a marked increase in the in vitro growth of B. microti. These findings suggest a suppression of B. microti in concurrently S. mansoni-infected mice induced by an immunological specific anti-2?. microti factor potentiated by the concurrent S. mansoni infection. The results do not indicate that activation of the mononuclear phagocytic system is of primary importance in suppression of B. microti in-concurrently S. mansoni infected mice.
