Abstract

Flagellate infections were found in 1,063 of 18,895 sand flies collected in the states of Amazonas, Pará, Rondonia and Acre, Brazil. Infection rates were 13.4% (species group ); 7.5% (subgenus ); 6.7% (subgenus series ); 0.5% (genus ) and 3.1% for other sand flies (various subgenera). and were isolated, respectively, from the known vectors, and . Single stocks of -like and -like organisms were isolated, respectively, from and . Thirty-eight flagellate stocks, isolated by direct culture from sand flies were characterized in detail by morphology in culture, behavior in hamsters and mice and by enzyme profiles. Sixteen stocks from sp. ( group) were identified as ; 8 stocks from sp. ( group) were identified as sp.; 7 stocks from and were identified as sp. previously isolated from the armadillo, ; 2 stocks of were isolated from recently fed sp. ( group) sand flies; the remaining 5 stocks from and could not be identified. Observations suggested that group sand flies were the natural vectors of sp. infections in the man-biting flies and were restricted to the midgut and associated with recent bloodmeals. Unidentified flagellates in and were distributed throughout the digestive tract with no trace of bloodmeals.
