Helminths from a stranded manatee in the Dominican Republic.

Endangered West Indian manatees (Trichechus manatus) are known to be parasitized by a number of helminths and ectoparasites. Records of parasitic associations exist for Florida, Mexico, Guyana, Brazil, Cuba and recently for Puerto Rico. Parasites of manatees in other Caribbean areas have not been documented, particularly from Hispaniola. We report on the occurrence of a species of nematode and of two trematodes from a 238-cm male manatee from Portillo (19 degrees 20' N, 69 degrees 35' W), Las Terrenas, in the Dominican Republic. Three species of helminths were collected, including the opisthotrematid Cochleotrema cochleotrema, the ascarid Heterocheilus tunicatus, and the paramphistomid trematode Chiorchis fabaceus. The documentation of these helminths constitutes the first record of these parasites and host relationships for Hispaniola and the second for the northeastern Caribbean.
