Cystidicola Farionis

Cystidicola farionis is reported in Coregonus clupeaformis, C. artedii, C. hoyi, C. nigripinnus (new host record), Prosopium cylindraceum, Oncorhynchus gorbuscha (new North American record), O. kisutch, O. tshawytscha (new host record), Salmo gairdneri, S. trutta, Salvelinus fontinalis, S. namaycush, S. namaycush × S. fontinalis, and Osmerus mordax. The last five fishes listed, however, are considered unsuitable hosts for C. farionis as few, if any, worms reached sexual maturity in these hosts. Coregonus clupeaformis is also unsuitable as a host for C. farionis in lakes Superior and Nipigon. The swim-bladder nematode that matures in lake whitefish in Lake Huron and some inland lakes in northwestern Ontario may be a new species.Factors that may affect the abundance of C. farionis in various fishes are examined and the relative importance of different amphipods as sources of infection is discussed.Cystidicola cristivomeri matures only in hosts of the genus Salvelinus, including S. namaycush and S. alpinus, and is reported here for the first time in S. fontinalis.Ulcerations in the wall of the swim-bladder were seen only in S. gairdneri infected with C. farionis and in S. namaycush infected with C. cristivomeri. The lesions apparently resulted when unusually large numbers of swim-bladder nematodes were present.

Migration And Development

Third-stage larvae of Cystidicola cristivomeri White, 1941, and C. farionis Fischer, 1798, migrated directly via the pneumatic duct to the swim bladder of lake trout, Salvelinus namaycush, and rainbow trout, Salmo gairdneri, respectively. Larvae reached the swim bladder as early as 16 h after fish were infected using a stomach tube. At 4–10 °C, mature male and female C. cristivomeri and C. farionis were first recovered 67 and 210 days, and 112 and 235 days, respectively, after infection. Cystidicola cristivomeri is probably long-lived; there was no evidence that any died in lake trout infected for up to 600 days.Large numbers of third-stage cystidicolid larvae accumulated without maturing in the swim bladder of naturally infected lake whitefish, Coregonus clupeaformis, from Lake Nipigon, northwestern Ontario. When given to rainbow trout, these larvae matured and the adult nematodes were identical to C. farionis. These results suggest that the swim-bladder nematode that matures in lake whitefish is a distinct species.

New Host Records

Sixty-seven salmonids and coregonids (32 Salvelinus fontinalis, 3 Salmo salar, 22 Salmo trutta, 10 Coregonus clupeaformis), caught at various locations on the Avalon Peninsula, Newfoundland, were examined for metazoan parasites, during the period November 15, 1968–June 12, 1969. Eight genera of helminths (two of Monogenea, three of Digenea, one each of Cestoda, Nematoda, Acanthocephala) and one of parasitic copepods (Ergasilus) were recovered. This number includes one new host record and two new host records for Newfoundland.

New Host Record

A novel species, Micropeltis goniothalamicola and a new record Scolecopeltidium menglaense were collected from Mae Fah Luang Botanical Gardens, Thailand. Our new taxon is different from other species in Micropeltis in having relatively smaller ascomata, 6–8-spored asci and 4–5-septate ascospores covering with mucilaginous sheath. Our new record, S. menglaense is the first host recorded from Jasmine grandiflorum (Oleaceae). Morphological comparison coupled with phylogenetic analysis of combined LSU and ITS sequence data provide evidence for the new species and new host record.

Tergestia laticollis (Rudolphi, 1819) is reported for the first time in South America and in Thunnus albacares, representing a new host record. Copiatestes filiferus (Leuckart, in Sars, 1885) is recorded for the first time in Brazil and in Thunnus albacares, another new host record. Tetrochetus coryphaenae (Yamaguti, 1934) is presented for the first time in Brazil parasitizing Thunnus albacares.

This study provides an update on the ectoparasites (ticks and leeches) associated with Rhinoclemmys annulata and provides new accounts on the ectoparasites associated with R. nasuta, R. melanosterna andKinosternon leucostomum from the Pacific coast of Colombia. The presence ofAmblyomma sabanerae on R. nasuta and R. melanosterna provided two new host records for the tick species. Also, the documentation ofA. sabanerae from the Department of Valle del Cauca represents a new department record for the species in Colombia. Placobdella ringueleti was identified fromR. nasuta and K. leucostomum, which represents a new host record for the leech species, as well as a significant extension of the known range.
