Abstract
Cultures of T. myoti did not survive in reduviids; they multiplied and developed in the human bedbug, C. lectularius. Although metatrypanosomes were always found in bedbugs fed on cultures of T. vespertilionis, this stage was rare in bugs fed on cultures or on bats infected with T. hedricki and T. myoti. Multinucleated forms and promastigotes were detected in bugs infected with T. hedricki and T. myoti, but these forms were not seen in T. vespertilionis infection. The patterns of development of T. hedricki and T. myoti in C. lectularius are similar to that of T. cruzi in reduviids. T. vespertilionis is different. Cultures (containing metatrypanosomes) of T. myoti and metatrypanosomes of the 3 trypanosome species from C. lectularius were not infective to mammals other than bats. The culture (containing metatrypanosomes) of T. myoti was infective to Myotis lucifugus. Metatrypanosomes of T. hedricki from C. lectularius fed on Eptesicus fuscus were subsequently infective to other E. fuscus.
