Myxozoan and Helminth Parasites of the Dwarf American Toad, Anaxyrus americanus charlesmithi (Anura: Bufonidae), from Arkansas and Oklahoma

Abstract

We examined 69 dwarf American toads, Anaxyrus americanus charlesmithi, fromMcCurtain County, Oklahoma (n = 37) and Miller, Nevada and Union counties, Arkansas (n = 32)for myxozoan and helminth parasites. The following endoparasites were found: amyxozoan, Cystodiscus sp., a trematode, Clinostomum marginatum, two tapeworms, Cylindrotaenia americana (Oklahoma only) and Distoichometra bufonis, five nematodes, acuariid larvae, Cosmocercoides variabilis, Oswaldocruzia pipiens, larval Physaloptera sp. (Arkansas only), and Rhabdias americanus (Arkansas only), and acanthocephalans (Oklahoma only). We document six new host and four new geographic distribution records for these select parasites.©2014 Oklahoma Academy of Science
