Resumen:
In June 2014, 30 marbled toads (Incilius marmoreus) from Oaxaca, Mexico
were examined for helminths. We collected a total of 3,783 helminths
belonging to 13 taxa: 4 digenean, 1 cestode, 1 acanthocephalan, and 7
nematoda. The nematode Physocephalus sp. was the most prevalent (63.3%)
followed by Aplectana sp., which had the highest mean intensity (114.3)
and mean abundance (63.8) that we recorded. The taxonomic composition of
I. marmoreus mainly consists of generalist helminths, with nematodes
being the predominant parasites found, confirming the terrestrial habits
of this toad. The main route of helminth acquisition was ingestion of
larvae and/or intermediate hosts, a process that also likely contributes
to the high abundance of individuals in the toads. The knowledge of the
helminth fauna associated to the 39 toad species distributed in Mexico
is scarce and fragmentary, and our study presents results for only the
second bufonid species studied in this region.
