Drake 2014 <p><span>One hundred specimens of </span><i><i>Rhinella marina</i></i><span>, (Anura: Bufonidae) collected in St. George's parish, Grenada, from September 2010 to August 2011, were examined for the presence of ectoparasites and helminths. Ninety-five (95%) were parasitized by 1 or more parasite species. Nine species of parasites were found: 1 digenean, 2 acanthocephalans, 4 nematodes, 1 arthropod and 1 pentastome. The endoparasites represented 98.9% of the total number of parasite specimens collected. Grenada represents a new locality record for </span><i>Mesocoelium monas, Raillietiella frenatus</i><span>, </span><i><i>Pseudoacanthacephalus</i></i><span> sp., </span><i><i>Aplectana</i></i><span> sp., </span><i><i>Physocephalus</i></i><span> sp., Acanthacephala cystacanth, and Physalopteridae larvae. The digenean </span><i>M. monas</i><span> occurred with the highest prevalence of 82%, contrasting many studies of </span><i><i>R. marina</i></i><span> where nematodes dominate the parasite infracommunity. Female toads were found to have a significantly higher prevalence of </span><i>Amblyomma dissimile</i><span> than male toads. Only 2 parasites exhibited a significant difference between wet and dry season with </span><i>Parapharyngodon grenadensis</i><span> prevalence highest in the wet season and </span><i>A. dissimile</i><span> prevalence highest during the dry season. Additionally, </span><i>A. dissimile</i><span>was significantly more abundant during the dry season.</span></p> application/pdf 10.1645/13-470.1 en American Society of Parasitologists Survey of helminths, ectoparasites, and chytrid fungus of an introduced population of cane toads, <i>Rhinella marina</i> (Anura: Bufonidae), from Grenada article
