A mixed population of Trypanozoon in Glossina palpalis palpalis from Ivory Coast.

Cloning trypanosomes clearly showed that at least two enzymically distinct populations of Trypanozoon were present within the salivary glands of a wild-caught Glossina palpalis palpalis from Ivory Coast. Normal sampling techniques detected only the predominant population, which would be the only population reaching a stage suitable for enzyme characterization. Thus a tsetse fly may fail to be implicated as a transmitter of man-infective trypanosomes. The enzymic relationship of the two Trypanozoon populations suggested genetic hybridization. The separate clones retained their individual enzymic integrity after blood and cyclic transmission.
