A survey conducted among the Makuxi Indians from 15 settlements in the northeastern part of the Territory of Roraima, Brazil, revealed the occurrence of Mansonella ozzardi in 3,2% (21/652) of the persons examined. The absence of demonstrable infection--with one exception--in persons under 15 years of age, and the low microfilaria density in adults suggest that mansonelliasis has been acquired by the Makuxi Indians outside their villages. As many Indians from the region pan gold on the Upper Maú (Ireng) river--where black flies occur in great quantity--the mining camps are probably the sites of transmission. Experimental infection with M. ozzardi of Simulium oyapockense s.l. (or Simulium roraimense) showed that this species, at the least in the Surumu river area, is capable of supporting the full development of the microfilariae. Although S. oyapockense has a wide distribution in the extreme north of Brazil, it does not appear to be an efficient vector, since only 20,6% (19/92) of the specimens collected after a blood meal on a naturally infected Indian contained larval stages of M. ozzardi (with an average of 1-2 larvae per fly). The high prevalence rate of infection found, in a previous survey, among the Sanumá and Mayongong, two Indian groups living at the Auaris river area, on the other side of the Territory of Roraima, indicates that a more competent intermediate host should exist in that region.
