The parasite fauna in cetaceans from Puerto Rico, the Virgin Islands, and the larger Caribbean region is poorly known. We provide the first records for parasite biodiversity among a diverse assemblage of cetaceans from the Caribbean Sea. Internal and external parasites and commensals were collected from stranded whales and dolphins salvaged in Puerto Rico, the United States and British Virgin I...

Most individuals in an infection of the acanthocephalan parasite Polymorphus minutus (Goeze, 1782) in domestic ducks are found in a region extending from 65% to 75% of the distance along the host's intestine (Crompton & Harrison, 1965). The exact location and mode of attachment of the parasites in this habitat has been described by Crompton, Shrimpton & Silver (1965). Acanthocephalans, like ces...

Host-parasite interactions of Pomphorhynchus laevis (Müller, 1776) in naturally infected amphipod, Echinogammarus stammeri (Karaman), from the Brenta River (northern Italy) are described. A fully developed acanthocephalan larva occupies a large portion of an amphipod's haemocoelic space; thus, the parasite frequently induces displacement of host digestive tract and other internal organs. Howeve...

The helminthological record of Rana cf. forreri in Acapulco municipality, Guerrero state, Mexico, consists of 19 taxa: 5 digeneans—Catadiscus rodriguezi, Haematoloechus coloradensis, metacercariae of Diplostomidae gen. sp., Mesostephanus sp., and Apharyngostrigea sp.; 2 cestodes—Cylindrotaenia americana and the plerocercoid of Diphyllobothriidae gen. sp.; 2 acanthocephalans—Neoechinorhynchus go...

The helminth Moniliformis dubius forms a convenient source of material for studying the biochemistry and physiology of acanthocephalans because it grows to a relatively large size and its life-cycle is easily maintained in the laboratory. The parasite develops in the haemocoele of the cockroach Periplaneta americana and sexual maturity is achieved in the small intestine of rats. Biochemical wor...

Published and personal records have been compiled into a reference list of the helminth parasites of guineafowls. Where data on other avian hosts was available these have been included for completeness' sake and to give an indication of host range. The parasite list for the Helmeted guineafowls, Numida meleagris, includes five species of acanthocephalans, all belonging to a single genus, three ...

The present work studied the prevalence and histopathology of Neoechinorhynchus curemai Noronha, 1973 (Acanthocephala; Neoechinorhynchidae) from curimbatá, Prochilodus lineatus Valenciennes, 1836. Eighteen fishes with averages of 46.7 +/- 1.1 cm length and 1,674.8 +/- 75.6 g weight were collected with net, bimonthly from December 1995 thru December 1996 in the hydroelectric power station of Vol...

Literature reviews of all references concerning the parasitic fauna of fishes in fish farms of Babylon province, middle of Iraq, showed that a total of 92 valid parasite species are so far known from the common carp (Cyprinus carpio), the grass carp (Ctenopharyngodon idella), and the silver carp (Hypophthalmichthys molitrix) as well as from three freshwater fish species (Carassius auratus, Liza...
