The ultrastructural cytology and reproduction of Amphiacantha longa Caullery et Mesnil, 1914 is described. Merogonial reproduction was not observed. The sporogony follows two lines: free disporoblastic and enveloped, polysporoblastic, involving sporoblast mother cells. The enveloped sporogony is endogenous in spore sacs of sporont origin, daughter cells are formed by vacuolation. Probably all stages have coupled nuclei. Both free and enveloped spores are equipped with an extrusion apparatus composed of a flat polar sac, a straight polar filament of manubrium type, and a posterior globular appendix. Manubrium and appendix are enclosed in a membraneous...

The cytology of a new microsporean parasite Microsporidium epithelialis sp. n. from the intestinal epithelial cells of the freshwater oligochaete Tubifex sp. (Tubificidae) is described. The microsporean occurred together with an actinosporean of the genus Triactinomyxon, which was found between the epithelial cells. The merogonic and sporogonic stages (mature spores included) of the microsporean parasite are monokaryotic. An individual sporophorous vesicle surrounds each spore. The fixed and stained spore has an average dimension of 1.9-2.5 × 0.9-1.2 µm. The spores are oval with a characteristic surface layer, showing ornamentation-like...

A 33-35 kDa circulating antigen from Plasmodium falciparum
Neirade Dominguez, Alexis Rodriguez-Acosta
Folia Parasitologica 47 267-272 (2000) | 10.14411/fp.2000.046
Isolation and characterisation of Plasmodium falciparum (Welch, 1897) soluble antigens from infected patient plasma, Western blotting, thermal stability and ELISA assays using hyperimmune IgG-antimalaria antibodies was the main objective of this work. A circulating antigen of approximately Mr 33-35 kDa with good specificity and antigenicity, in the plasma of malarial patients was shown. Heating at 100ºC did not destroy its antigenicity. When fractions highly enriched in the 33-35 kDa proteins were used in ELISAs, a seroreactivity in plasma obtained from primary-infected individuals was found. Controls from normal patients were always negative....
Infections of Unicauda clavicauda (Kudo, 1934) (Myxozoa) in the skin of Notropis hudsonius (Cyprinidae) from Montana, with a synopsis of the genus Unicauda Davis, 1944
David K. Cone, Jason S. Melendy
Folia Parasitologica 47 273-278 (2000) | 10.14411/fp.2000.047
Infections of Unicauda clavicauda (Kudo, 1920) Davis, 1944 (Myxozoa) are described from Notropis hudsonius (Clinton) in Montana. Plasmodia form beneath scales of the body and produced spores within a loosely-defined matrix. Fixed spores are oval in front view, 11-14 µm long and 9-10.5 µm wide, and contain a posterior appendage that is up to 26 µm long. The polar capsules are 4-6 µm long and 2.5-4 µm wide. The study represents the first report of U. clavicauda since the original species description and a new host and geographical record. The taxonomic history of Unicauda Davis, 1944 is summarised...
Paranaella luquei gen. et sp. n. (Monogenea: Microcotylidae), a new parasite of Brazilian catfishes
Anna Kohn, Mariade Fatima D. Baptista-Farias, Simone Chinicz Cohen
Folia Parasitologica 47 279-283 (2000) | 10.14411/fp.2000.048
Paranaella, a new microcotyline monotypic genus, is erected to accommodate Paranaella luquei sp. n., parasite of gill filaments from Hypostomus sp., Hypostomus regani (Ihering) and Rhinelepis aspera Spix et Agassiz (Loricariidae) from the Paraná River, Brazil. The new genus is most closely related to Microcotyle Van Beneden et Hesse, 1863, Diplostamenides Unnithan, 1971 and Solostamenides Unnithan, 1971. From Microcotyle it differs mainly by having the genital atrium formed by a muscular ring with a concentric row of numerous elongate and straight spines; from Diplostamenides it...

Tetraphyllidean metacestodes of teleosts of the Great Barrier Reef, and the use of in vitro cultivation to identify them
Clinton B. Chambers, Thomas H. Cribb, Malcolm K. Jones
Folia Parasitologica 47 285-292 (2000) | 10.14411/fp.2000.050
The tetraphyllidean metacestode diversity of 310 teleost fishes, including 87 species from 31 families, was examined from Heron Island, The Great Barrier Reef, Australia. Eleven metacestode 'types' were identified with the use of light microscopy. Host-specificity varied greatly among metacestode types. Incorporation of in vitro cultivation allowed generic identification for some types. Types 1 and 2 belong to Uncibilocularis Southwell, 1925, and have triloculate bothridia and one pair of forked hooks with unequal prongs; Type 3 has quadriloculate bothridia. Hook development was insufficient to determine in which genus, Acanthobothrium...
New records of trypanorhynch cestodes from the Gulf of Mexico, including Kotorella pronosoma (Stossich, 1901) and Heteronybelinia palliata (Linton, 1924) comb. n.
Harry W. Palm, Robin M. Overstreet
Folia Parasitologica 47 293-302 (2000) | 10.14411/fp.2000.051
Four trypanorhynchs, Kotorella pronosoma (Stossich, 1901), Nybelinia cf. bisulcata (Linton, 1889), Nybelinia scoliodoni (Vijayalakshmi, Vijayalakshmi et Gangadharam, 1996), and Dasyrhynchus pacificus Robinson, 1965 are reported for the first time from the Gulf, which is now known to harbour at least 34 different species. In addition to the range extension for the trypanorhynchs listed above, 21 new host records are reported involving 13 cestode species. Characters of the genus Kotorella Euzet et Radujkovic, 1989 are emended, Nybelinia narinari MacCallum, 1917 is considered a junior synonym of Kotorella...
Chimaerula bonai sp. n. (Cestoda: Dilepididae) from the bare-faced ibis, Phimosus infuscatus (Lichtenstein) (Aves: Threskiornithidae) in Paraguay
Boyko B. Georgiev, Claude Vaucher
Folia Parasitologica 47 303-308 (2000) | 10.14411/fp.2000.052
Chimaerula bonai sp. n. is described from the small intestine of Phimosus infuscatus (Lichtenstein) in Paraguay. The new species differs from the other two species of Chimaerula Bona, 1994, i.e., Chimaerula woodlandi (Prudhoe, 1960) and Chimaerula leonovi (Belogurov et Zueva, 1968), mainly by the intermediate number of rostellar hooks (30-34 compared to 42-46 in the former and 20-22 in the latter), longer rostellar hooks (31-34 µm versus 26 µm and 19-21 µm, respectively), shorter cirrus sac (58-82 µm versus 158-201 µm and 134-183 µm, respectively) and the absence of rosethorn spines...
Huffmanela paronai sp. n. (Nematoda: Trichosomoididae), a new parasite from the skin of swordfish Xiphias gladius in the Ligurian Sea (Western Mediterranean)
František Moravec, Fulvio Garibaldi
Folia Parasitologica 47 309-313 (2000) | 10.14411/fp.2000.053
A new species of trichosomoidid nematode, Huffmanela paronai sp. n., is established on the basis of its egg morphology and biological characters. The dark-shelled, embryonated eggs of this histozoic parasite occur in masses in the epidermis of the swordfish Xiphias gladius L. (Xiphiidae, Perciformes) from the Ligurian Sea in northern Italy. The eggs are concentrated in groups appearing as black spots in the skin of the fish host, being distributed mainly on the lower part of its body (lower jaw, gill covers, pectoral, anal and caudal fins, lower half of body). The parasite's eggs are characterised mainly by their shape and markedly small...

Comparison of the Galleria baiting technique and a direct extraction method for recovering Steinernema (Nematoda: Rhabditida) infective-stage juveniles from soil
Dieter Sturhan, Zdeněk Mráček
Folia Parasitologica 47 315-318 (2000) | 10.14411/fp.2000.055
Forty soil samples from forests and other biotopes in Germany and the Czech Republic were studied for the presence of entomopathogenic nematodes using the Galleria bait method at the same time as a sieving-decanting method for direct extraction of infective-stage juveniles. Five Steinernema species were recovered from the samples from Germany and four species from the samples from Czechia. All five species were recovered with both methods, but the baiting technique was generally less effective and mixtures of species were frequently undetected. The direct extraction method provided quantitative estimates of infective-stage juvenile density...

Folia Parasitologica 47 319-329 (2000) | 10.14411/fp.2000.056
Four new species of feather mites belonging to three different genera of the family Pteronyssidae are described from passerine birds of South Africa: Pteroherpus africanus sp. n. from the garden bulbul Pycnonotus barbatus (Desfontaines) (Pycnonotidae), Pteroherpus cysticolae sp. n. from the wing-snapped cisticola Cisticola ayresii Hartlaub (Sylviidae), Pteronyssoides promeropis sp. n. from the Gurney's sugarbird Promerops gurneyi Verreaux (Promeropidae), and Sturnotrogus creatophorae sp. n. from the wattled starling Creatophora cinerea Menschen (Sturnidae).
