| Notes | "This study was undertaken: (1) to obtain information on the distribution of the snail, Oxytrema silicula, in three coastal rivers in Oregon, and the seasonal incidence of infection in these snails and in snails from an inland stream, with the cercariae of the trematode, Nanophyetus salinincola; (2) to follow cercarial development in the snail under natural and experimental conditi is; (3) to determine the species of animals naturally infected with the metacercariae and those susceptible to experimental infection; and (4) to follow development of the metacercariae in the fish hosts... The fishes Cottus perplexus, Lampetra richardsoni, L. tridentata, and Richardsonius balteatus, and the Pacific giant salamander, Dicamptodon ensatus, all from western Oregon streams, were found naturally infected with the metacerariae of N. saimincola. This is the first report of natural infections in an animal other than a fish and in nonsalmonid fishes. .." (from the Abstract) Major professor was Raymond Milleman. |
