Abstract:
Blastocrithidia triatomae parasitizes triatomine bugs, the vectors of Chagas disease. Co-cultivation with a host-derived cell line permits continuous culture but the host cells are destroyed. Removal of the reduviid cells induces the formation of drought-resistant cysts, but the factors that induce encystment are unknown. Excystment is triggered after the onset of blood digestion in the insect host, a transition that is associated with unusual ultrastructural alterations. Günter Schaub, Dagmar Reduth and Mary Pudney believe that B. triatomae is a good candidate for the biological control of Chagas disease, not least because of its capacity to form highly resistant cysts in vitro.
