Folia Parasitologica 51[1] 1-13 (2004) | DOI: 10.14411/fp.2004.001

The nematode superfamily Dracunculoidea includes 166 recognized species, of which 150 (90%) are parasitic in about 300 species of freshwater, brackish-water and marine fishes. Fish dracunculoids are placed in 31 genera (86% of all dracunculoid genera) belonging to eight of the nine dracunculoid families: Anguillicolidae, Daniconematidae, Guyanemidae, Lucionematidae, Micropleuridae, Philometridae, Skrjabillanidae, and Tetanonematidae; the genus Lockenloia is considered incertae sedis. Because of difficulties in studying fish dracunculoids, associated with their morphological and biological peculiarities, most species of these largely histozoic...

Folia Parasitologica 51[1] 14-18 (2004) | DOI: 10.14411/fp.2004.002

Nereis diversicolor O.F. Müller and N. succinea Frey et Leuckart (Polychaeta, Nereidae) living in brackish shallow areas in Denmark are naturally infected with tetractinomyxon actinospores. Infected Nereis spp. were experimentally fed to various potential fish hosts, and the actinosporean stages developed into myxosporean stages of Ellipsomyxa gobii Køie, 2003 (Ceratomyxidae) in the gallbladder of the common goby Pomatoschistus microps (Krøyer) (Gobiidae). The European eel Anguilla anguilla (L.), three-spined stickleback Gasterosteus aculeatus L., small sand eel Ammodytes tobianus...

Morphology and ultrastructure of Sphaeromyxa noblei sp. n. (Myxozoa), parasite of Heteroclinus whiteleggii (Pisces) from Australian New South Wales coast

Folia Parasitologica 51[1] 19-26 (2004) | DOI: 10.14411/fp.2004.003

A new species, Sphaeromyxa noblei sp. n., is described from Heteroclinus whiteleggii (Perciformes: Clinidae), a marine fish from the coast of New South Wales in Australia. This raises the number of Sphaeromyxa species to 38; their list is presented. The species is characterised by a layer of branched glycostyles, which is about 2.4 µm thick and is a feature rather unique in Myxosporea. Pansporoblasts form one or two spores. The study of ultrastructure of this species and of those described to date result in recognition of a combination of patterns characterising the genus: plasmodia have marked surface projections, the endoplasm...

Transmission electron microscopy of presumed sensory receptors in the forebody papillae of Crepidostomum metoecus (Digenea: Allocreadiidae)

Zdeňka Žďárská, Jana Nebesářová

Folia Parasitologica 51[1] 27-32 (2004) | DOI: 10.14411/fp.2004.004

Five types of presumed ciliate sensory receptors were detected in the forebody papillae of the adult fish trematode, Crepidostomum metoecus (Braun, 1900). The cilia are short and submerged in a tegumental pit. The apical bulb part of all types of receptors observed is supported by a dense collar and connected to the tegument basal plasma membrane by a circular septate junction. In sensory receptors types I and III no rootlet is present; the bulbs of sensory receptors types III and IV contain an electron-dense formation.

Review of the genus Progrillotia Dollfus, 1946 (Cestoda: Trypanorhyncha), with a redescription of Progrillotia pastinacae Dollfus, 1946 and description of Progrillotia dasyatidis sp. n.

Folia Parasitologica 51[1] 33-44 (2004) | DOI: 10.14411/fp.2004.005

Progrillotia pastinacae Dollfus, 1946 (Cestoda: Trypanorhyncha) is redescribed from the spiral valve of Dasyatis pastinaca (Linnaeus) (Dasyatididae) from the coast of France. Progrillotia dasyatidis sp. n. is described from the spiral valves of Dasyatis tortonesei Capapé (Dasyatididae) from the Mediterranean in the Gulf of Gabès (Tunisia) and D. pastinaca from the Bassin d'Arcachon (France). The new species differs from congeners in having, on the tentacles, a single rather than two rows of intercalary hooks and fewer testes. The generic definition is emended based upon the new species, the redescription of...

First record of metacestodes of Mesocestoides sp. in the common starling (Sturnus vulgaris) in Europe, with an 18S rDNA characterisation of the isolate

Ivan Literák, Peter D. Olson, Boyko B. Georgiev, Marta Špakulová

Folia Parasitologica 51[1] 45-49 (2004) | DOI: 10.14411/fp.2004.006

Metacestodes of Mesocestoides sp. were recorded from Sturnus vulgaris (Passeriformes: Sturnidae) in the Czech Republic in April 2002. They were found in a cutaneous cyst and in the thoracic region of the body cavity of the bird. This is the first record of metacestodes of Mesocestoides sp. in this host species in Europe as well as the first finding of the formation of a cutaneous cyst provoked by this parasite. Additional specimens from Apodemus agrarius (Mammalia: Rodentia) from Bulgaria and Lacerta agilis (Reptilia: Squamata) from the Czech Republic were compared with that from S. vulgaris. Sequence data...

Observations on the distribution and biology of Huffmanela huffmani (Nematoda: Trichosomoididae)

Marlin K. Cox, David G. Huffman, František Moravec

Folia Parasitologica 51[1] 50-54 (2004) | DOI: 10.14411/fp.2004.007

The nematode parasite Huffmanela huffmani Moravec, 1987 (Trichosomoididae) infects swimbladders of fishes in the family Centrarchidae. Only fish collected from the upper San Marcos River (Texas) have been found infected with H. huffmani eggs with a prevalence of 90%. Hundreds of thousands of H. huffmani eggs have been observed in these fish but only a few specimens of adult worms have ever been found. The San Marcos River arises from springs along the Balcones Fault Zone in San Marcos, Hays County, Texas. The restriction of the parasite to the upper San Marcos River and the high prevalence of the parasite eggs in centrarchids would...

Hysterothylacium winteri sp. n. (Nematoda: Anisakidae), a parasite of Chilean rock cod, Eleginops maclovinus (Perciformes: Eleginopidae), from South Chile

Patricio Torres, María Soledad Soto

Folia Parasitologica 51[1] 55-60 (2004) | DOI: 10.14411/fp.2004.008

Hysterothylacium winteri sp. n. (Nematoda: Anisakidae) was collected from the intestine of a marine-estuarine fish, Eleginops maclovinus (Valenciennes) (Perciformes: Eleginopsidae), from Abtao in the Gulf of Ancud, Chile. Sixteen (51.6%) out of 31 fish were infected; the intensity was 1-10 (mean 4) worms/host. The new species belongs to the group of congeners possessing one double pair of postanal papillae. By possessing a lateral pair of phasmids situated near the tip of tail, H. winteri most closely resembles Hysterothylacium habena. The new species can be distinguished by the lip flanges forming broadly rounded points...

The role of mite pocket-like structures on Agama caudospinosa (Agamidae) infested by Pterygosoma livingstonei sp. n. (Acari: Prostigmata: Pterygosomatidae)

Michel Bertrand, David Modrý

Folia Parasitologica 51[1] 61-66 (2004) | DOI: 10.14411/fp.2004.009

Pterygosoma livingstonei sp. n. collected from the Kenyan lizard Agama caudospinosa Meek shows morphological affinities with other South African congener species parasitizing lizards of the genus Agama, especially with P. triangulare Lawrence, 1936, but it differs in having glabrous genua II and III. P. livingstonei shows affinities with the Lawrence's hispida species group in the characters of genital and peripheral setae. This new species was found concentrated in a nuchal "mite pocket-like structure", a behaviour previously unreported among species belonging to the genus Pterygosoma. Mite pockets...

Folia Parasitologica 51[1] 67-71 (2004) | DOI: 10.14411/fp.2004.010

The possibility of vertical transmission of Borrelia burgdorferi sensu lato in Ixodes persulcatus Schulze, 1930 ticks was studied in the progeny of 20 females collected from the vegetation in an active focus of ixodid tick-borne borrelioses (ITBB) located in the Perm oblast, Russia, where Borrelia garinii and B. afzelii are circulating. The presence of Borrelia DNA was detected by the PCR method after feeding and egg laying in 16 engorged females (80.0%), as well as in 36.5 ± 7.2% samples containing 20 eggs each and in 21.4 ± 4.2% samples containing 10 eggs each. The respective rates of individual egg infection...

Echinorhynchus salmonis Müller, 1784 absent in Britain and Ireland: re-identification of museum specimens

James C. Chubb

Folia Parasitologica 51[1] 72-74 (2004) | DOI: 10.14411/fp.2004.011

Collections of 'Echinorhynchus salmonis' from Britain and Ireland deposited in The Natural History Museum, London (1921.7.19.3-12 and 1952.10.30.122-127) were re-identified as Acanthocephalus clavula and Acanthocephalus lucii respectively. The amphipod, Pontoporeia affinis, European intermediate host of E. salmonis, does not occur in the British Isles, so it is concluded that E. salmonis is absent from British and Irish freshwater fishes.

The systematic status of Philometra abdominalis Nybelin, 1928 (Nematoda: Philometridae) [= a junior synonym of P. ovata (Zeder, 1803)]

František Moravec

Folia Parasitologica 51[1] 75-76 (2004) | DOI: 10.14411/fp.2004.012

Examination of the original literature concerning species of Philometra (Philometridae, Dracunculoidea) parasitic in the abdominal cavity of European cyprinids revealed that P. abdominalis Nybelin, 1928 is a junior synonym of P. ovata (Zeder, 1803), a parasite of cyprinids of the genera Gobio, Phoxinus and Leuciscus. The valid name of the species parasitizing cyprinids of the genera Abramis, Rutilus and Vimba, mostly reported erroneously as P. ovata, is P. cyprinirutili (Creplin, 1825) comb. n.
