Helminths of the Western Toad, Bufo boreas (Bufonidae) from Southern California

Abstract

Museum specimens of Bufo boreas from southern California were ex- <br /><br />amined for helminths. The helminth fauna consisted of one trematode species, <br /><br />Haematoloechus kernensis, one cestode species, Distoichometra bufonis, six nem- <br /><br />atode species, Aplectana itzocanensis, Cosmocercoides variabilis, Falcaustra in- <br /><br />glisi, Oswaldocruzia pipiens, Rhabdias americanus, Physaloptera sp. (third stage <br /><br />larvae only). Helminths found in B. boreas are generalists occurring in other <br /><br />anuran species. Bufo boreas represents a new host record for H. kernensis, A. <br /><br />itzocanensis, F. inglisi, and Physaloptera sp. (larvae).
