Bolbophorus trematodes in fish recently gained national attention because B. damnificus infections have caused major losses of commercially raised channel catfish Ictalurus punctatus . We report the presence of a mixed infection ( B. damnificus and Bolbophorus sp.) in fathead minnow Pimephales promelas . Of the 10 trematodes identified by Bolbophorus spp.−specific polymerase chain reaction assays, 9 were Bolbophorus sp. and 1 was B. damnificus . This is the first report of a natural infection of B. damnificus in a nonictalurid host. In fathead minnow, the prodiplostomula examined histologically were surrounded by thin‐walled cysts; rarely, the cysts were accompanied by an inflammatory reaction that consisted primarily of macrophages.
