Helminth parasites of the osprey, Pandion haliaetus, in North America

A total of 28 species of helminths (17 trematodes, 3 cestodes, 7 nematodes, and 1 acanthocephalan) was recovered from 17 ospreys ( Pandion haliaetus ) from the United States. Intensities of infection were low and no lesions were attributed to the parasites. Seven species appear to be specialists in ospreys, 2 species generalists in raptors, and the remainder generalists in other orders of fish-eating birds. Pandiontrema rjikovi , Diasiella diasi , and Contracaecum pandioni are reported for the first time from North America.

Helminth parasites of the bald eagle, Haliaeetus leucocephalus, in Florida

Twenty species of helminths (9 trematodes, 9 nematodes, and 2 acanthocephalans), including 9 new host records, were collected from 40 bald eagles (Haliaeetus leucocephalus) from Florida. Intensities of infection were low and no lesions were attributed to the parasites. No species were considered specialists in bald eagles; 5 species were considered raptor generalists and the remainder, generalists in other orders of fish-eating birds. An undescribed species of Hamatospiculum was found in 3 birds. Most of the common helminths were acquired from eating fish intermediate hosts.

Parasites and commensals of the West Indian manatee from Puerto Rico

Metazoan parasites and commensals were collected from dead manatees salvaged in Puerto Rico. Thirty-five manatees were examined between 1980 and 1998. Parasites and commensals were identified in 20 (57%) manatees and included 3 species of helminths, 1 nematode (Heterocheilus tunicatus) and 2 digeneans (Chiorchis fabaceus and Cochleotrema cochleotrema). Two species of commensals were also associated with manatees: a barnacle (Chelonibia manati) and a fish (whitefin remora, Echeneis neucratoides). The 3 species of helminths found in manatees constitute the first records of these parasite-host relationships for the study area. The record of C. manati is the first for the Caribbean, and thus the species is not endemic to the Gulf of Mexico as previously described. The speculation that West Indian manatees closer to the center of their geographic distribution would have a greater diversity of parasites was found not true for these insular specimens but perhaps could be true for continental South American specimens.
