Resumo
This is the first record of gregarine infection in the worker midgut of the Neotropical termites Ruptitermes pitan and Ruptitermes reconditus. Gregarines have already been described in the gut and hemocoel in workers of other termite species, and although these protozoa are not able to kill these insects, they may affect their fitness. In the present study, gregarines were only observed in the gut lumen or linked to the midgut wall of termite workers. Histological sections of the worker midgut of Ruptitermes spp. showed three phases of the gregarine life cycle with the same individual worker displayed up to 4 gamonts and 2 trophozoites.
