Full Text: To determine potential definitive hosts of the digenetic trematode, Bolbophorus damnificus, 2 American white pelicans (Pelecanus erythrorhynchos), 2 double-crested cormorants (Phalacrocorax auritus), 2 great blue herons (Ardea herodias), and 2 great egrets (Ardea alba) were captured, treated with praziquantel, and fed channel catfish (Ictalurus punctatus) infected with B damnificus metacercariae. Patent infections of B damnificus, which developed in both American white pelicans at 3 days postinfection, were confirmed by the presence of trematode ova in the feces. Mature B damnificus trematodes were recovered from the intestines of both pelicans at 21 days postinfection, further confirming the establishment of infection. No evidence of B damnificus infections was observed in the other bird species studied. This study provides further evidence that double-crested cormorants, great blue herons, and great egrets do not serve as definitive hosts for B damnificus.
