A total of 443 specimens of three redfish species (209 Sebastes fasciatus, 123 S. marinus, and 111 S. mentella), obtained from Northwest Atlantic Fisheries Organization (NAFO) divisions 2H, 2J (Labrador area), 3K (Northeastern Newfoundland), 3L, 3O (Grand Banks) 3M (Flemish Cap), and 3Ps (St. Pierre Bank) during 1980–1982, was examined for metazoan parasites; 182 (87.1%) S. fasciatus, 120 (97.6%) S. marinus, and 103 (92.8%) S. mentella were infected. Seventeen species of parasites were recovered (12 from S. fasciatus, 16 from S. marinus, and 11 from S. mentella). 22 of which were new host records. Quantitative data, including prevalence and intensity of infection, are given for each parasite by host species and NAFO division. The zeogeography and host specificity of the parasites encountered in this study are discussed in relation to redfish and hypothetical stocks of Sebastes spp. are proposed based on the parasite data collected.

One hundred and seventy-five (94 surf, 36 white-winged, and 45 black) scoters obtained from four localities (New Brunswick, British Columbia, Labrador, and Norway) in 1973–1978 were examined for metazoan parasites, with 91% (159 birds: 86 surf, 33 white-winged, and 40 black scoters) being infected. Approximately 45 species of parasites, excluding cestodes, were found (36 from the surf, 25 from the white-winged, and 27 from the black), including 39 which were new host records. Quantitative data, including prevalence and intensity of infection, are given for each helminth and host. Comparisons between different ages and sexes are made, and between different host species. Individual species of parasites are discussed with regard to topics such as location within host. Comments are made on the geographical distribution of the parasites found and their life cycles, where known (seven cycle through the marine ecosystem, seven through freshwater, four through either system, and one through a dipteran).

808 cunners,Tautogolabrus adspersus(Walbaum) were obtained from eight sampling stations around the Newfoundland coast, during the periods August-September, 19G7 and July-October, 1908. The fish were examined for metazoan parasites using conventional parasitological techniques. 22 species of parasites (10 trematode; 5 cestode; 6 nematode; 1 acanthocephalan) were recovered. This number excludes metacercariae ofCryptocotyle lingua(Creplin, 1825). 19 are new host records. Details of infections with the various species are given, each species being discussed and/or described individually. No leeches were found on this host despite the fact that it lives in. close proximity to other fish species that are heavily infested and an experiment performed to determine if leeches would move from one host species to another gave negative results.

Faunal Survey

This paper constitutes the first ectoparasite faunal survey of bats for Marinduque Island, Philippines. From 1–12 June 2010, 150 bats belonging to 11 species were captured in 11 caves on the island. Each bat was sampled for ectoparasitic arthropods, and a total of 587 individuals representing 21 species, belonging to five families (Acari: Argasidae and Spinturnicidae; Diptera: Nycteribiidae and Streblidae; and Siphonaptera: Ischnopsyllidae) were collected. New host records (new host record) in the Philippines for Brachytarsina cucullata Jobling 1934, B. proxima Jobling 1951, B. werneri Jobling 1951, Raymondia pseudopagodarum Jobling 1951, Eucampsipoda philippinensis Ferris 1924, Nycteribia allotopa Speiser 1901, Nycteribia allotopoides Theodor 1963, Nycteribia parvuloides Theodor 1963, Ancystropus taprobanius (Turk 1950), and Carios batuensis Hirst 1929 were documented. A checklist of the ectoparasitic species known from the Philippines, their distribution, and bat host species is provided.

Using available records, unpublished information retrieved from the Helminthological Collection of the Oswaldo Cruz Institute (CHIOC) and published reports, a checklist of the recorded helminth parasites of endangered vertebrates from Brazil was generated. A total of 772 records and 186 helminth species (6 Acanthocephala, 83 Nematoda, 23 Cestoda, 64 Trematoda, 10 Monogenea) in 76 host species (7 Actinopterygii, 8 Chondrichthyes, 1 Amphibia, 10 Reptilia, 22 Aves, 28 Mammalia) from Brazil were listed in the present work, including 39 undetermined helminth species and 10 new host records. This is the first compilation of the helminth parasites of threatened vertebrates in Brazil and in the Neotropics.

AbstractThree species of belonid fish, Belone belone gracilis Lowe, 1839, Belone svetovidovi Collette & Parin, 1970 and Tylosurus acus imperialis (Rafinesque, 1810), caught off the eastern Tunisian coast were infected with eight species of Digenea. Among these, four species were commonly found in B. b. gracilis and are new host records for B. svetovidovi. They are: Lecithostaphylus retroflexus (Molin, 1859), Tergestia acanthocephala (Stossich, 1887) Stossich, 1899 and Aponurus laguncula Looss, 1907 in the intestine, and the metacercaria Condylocotyla pilodora Pearson and Prévot, 1985 in the pericardial sac. Four other digenean species were recorded from T. a. imperialis: Lecithostaphylus tylosuri Châari et al., 2013 and Tetrochetus coryphaenae Yamaguti, 1934 in the intestine, Oesophagotrema mediterranea Châari et al., 2011 in the oesophagus and vomer teeth, and Sclerodistomoides pacificus Kamegai, 1971 in the gall bladder. Tetrochetus coryphaenae and S. pacificus represent new host and geographical records. The spatial variation of digenean parasites within belonid host species is discussed.

AbstractNinety-five specimens from 13 species of lizard collected during a herpetofaunal monitoring programme of the Faxinal II power plant, municipality of Aripuanã, state of Mato Grosso, Brazil (southern Amazon region) were examined for helminths. A total of 21 helminth species (16 Nematoda, 1 Cestoda and 4 Trematoda) were recovered, with an overall prevalence of 67.37%. Seventeen new host records and seven new locality records are reported. A low number of specialists and core helminth species were found. Lizard body size was positively correlated with both the total number of helminth species and individuals. Active foragers exhibited higher helminth diversity. However, sit-and-wait foragers, especially Plica plica, had similar diversity values as active foragers and harboured more helminth species. The degree of similarity in helminth fauna was higher among closely related host species.

Using information from all published reports and data collected during several parasitological surveys between April 2003 and September 2009, a checklist of the parasites of fishes from Guandu River, southeastern of Brazil was generated. A total of 85 parasite species, 54 named species (1 Acanthocephala, 1 Cestoda, 2 Crustacea, 13 Digenea, 11 Nematoda, 23 Monogenea and 3 Myxozoa) and 31 undetermined species (3 Acanthocephala, 2 Cestoda, 1 Crustacea, 8 Digenea, 8 Nematoda, 4 Hirudinea, 3 Monogenea and 2 Myxozoa) in 21 fish host species from Guandu River, were listed in the current study, including 36 new locality records and 36 new host records. Also, a host-parasite list is included herein.

Forty short-tailed weasels (Mustela erminea Linnaeus, 1758) and 48 mink (Mustela vison Schreber, 1777) were collected, between January 1978 and February 1979, in three areas of insular Newfoundland and examined for metazoan parasites. Eight genera of parasites were recovered. Two findings constitute new host records. Forty (100%) of the M. erminea and 17 (35%) of the M. vison were infected. The effect of one species, Skrjabingylus nasicola (Leuckart, 1842), on the skull of the weasels was examined, and comments are made on its increase in prevalence with the introduction to insular Newfoundland of the masked shrew (Sorex cinereus Kerr, 1792) in 1958.Gut contents of both M. erminea and M. vison were identified and the percentage occurrence of different food items was calculated. In the case of the former species a marked change in diet, from lagomorphs and passerines to insectivores, was noted when the present (1978–1979) sample was compared with a 1956–1958 sample.
