Electron microscopic studies of the commonly occurring parasite, Demodex folliculorum, revealed interesting features concerning the ultrastructure of this acarid. The most significant finding was the presence of bacteria located superficially on its body. The vector potential of Demodex folliculorum is noted, the role probably being in the nature of a mechanical type of vector.
