Vexillifera expectata sp. n. and other non-encysting amoebae isolated from organs of freshwater fish

Dykova I, Lom J, Machackova B, Peckova H

Folia Parasitologica 45[1] 17-26 (1998)

Four strains of non-encysting amoebae were isolated from organs of freshwater fishes and characterized using light and electron microscope. Morphology of three clonal strains was consistent with amoebae which had already been described from water habitats. Two strains, one isolated from kidney tissue of common goldfish, Carassius auratus (Linnaeus, 1758), and the second one from brain of chub, Leuciscus cephalus Linnaeus, 1758, were identified with Vannella platypodia (Glaser, 1912) Page, 1976. Both strains were identical, except for the length of glycostyles. The strain isolated from the liver of perch, Perca fluviatilis (Linnaeus, 1758), was assigned...

Scolex morphology of Proteocephalus tapeworms (Cestoda : Proteocephalidae), parasites of freshwater fish in the Palaearctic Region

Scholz T, Drabek R, Hanzelova V

Folia Parasitologica 45[1] 27-43 (1998)

The morphology of the scoleces of 11 Proteocephalus species, parasites of freshwater fish in the Palaearctic Region, was compared using light and scanning electron microscopy. The following taxa were evaluated: Proteocephalus ambiguus (Dujardin, 1845); P. cernuae (Gmelin, 1790); P. exiguus La Rue, 1911; P. filicollis (Rudolphi, 1802); P. mucrocephalus (Creplin, 1825); P. osculatus (Goeze, 1782); P. percae (Muller, 1780); P. pollanicola Gresson, 1952; P. sagittus (Grimm, 1872); P. thymalli (Annenkova-Chlopina, 1923); and P. torulosus (Batsch, 1786). Some features as overall shape of the scolex, its size, shape and size of an apical sucker were found...

Redescription of the type-species of the cestode genus Deltokeras (Cyclophyllidea : Paruterinoidea)

Georgiev BB, Genov T

Folia Parasitologica 45[1] 44-46 (1998)

The syntypes of Deltokeras ornitheios Meggitt, 1927 (the type-species of Deltokeras Meggitt, 1927), a parasite of Urocissa erythrorhyncha (Passeriformes, Corvidae) in South Asia, are redescribed. Deltokeras is considered a monotypic genus. An amended generic diagnosis is presented.

Histopathological reactions of the blue shark, Prionace glauca, to postlarvae of Hepatoxylon trichiuri (Cestoda : Trypanorhyncha : Hepatoxylidae) in relationship to scolex morphology

Campbell RA, Callahan C

Folia Parasitologica 45[1] 47-52 (1998)

Postlarvae of the cestode Hepatoxylon trichiuri (Holten, 1802) were found attached to the surface of viscera of Prionace glauca (Linnaeus, 1758) taken from Atlantic coastal waters off the south coast of Massachusetts, USA, Gross anatomy of the attachment site shows a quadripartite rim surrounding a deep pit with holes corresponding to the penetration site of each tentacle. Hyperplasia of the liver capsule into outgrowths at the attachment site conform to the attachment of the bothridia. The cuboidal epithelium of the liver capsule became columnar forming papillary outgrowths, with a dense fibrotic reaction beneath the attachment site and infiltration...

Subclasses of IgG in different aged rats with fasciolosis

Paz A, Sanchez-Andrade R, Diez-Banos P, Panadero R, Morrondo P

Folia Parasitologica 45[1] 53-56 (1998)

The variations in antibody responses (total IgG and IgG1, IgG2a, IgG2b, and IgG2c subclasses) were studied in two groups of rats infected with metacercariae of the trematode Fasciola hepatica L. Animals of group 1 were 4 weeks old, and rats of group 2 were 13 weeks old. All IgG subclasses increased during the course of infection except IgG2c, which decreased. The younger rats reached more marked responses than the older, at least during the period of this trial. IgG1 and IgG2a antibodies reached the highest levels, and among these two, IgG2a response was slightly superior to IgG1.

Lucionema balatonense gen. et sp. n., a new nematode of a new family Lucionematidae fam. n. (Dracunculoidea) from the swimbladder of the European pikeperch, Stizostedion lucioperca (Pisces)

Moravec F, Molnar K, Szekely C

Folia Parasitologica 45[1] 57-61 (1998)

A new nematode genus and species, Lucionema balatonense gen. et sp. n., is described from the swimbladder of the European pikeperch, Stizostedion lucioperca (L.), from Lake Balaton in Hungary; a new dracunculoid family Lucionematidae fam. n. is established to accommodate it. The hitherto monotypic family Lucionematidae shows affinities with the families Skrjabillanidae and Daniconematidae, differing from them mainly in having simple oesophagus without external oesophageal glands and the vulva situated near the middle of body; from the first family also in the absence of the buccal capsule and the bursa-like caudal alae in the male. The genus Lucionema...

Chemical stability of assembly pheromone of argasid ticks (Ixodoidea : Argasidae)

Dusbabek F, Zahradnickova H, Simek P

Folia Parasitologica 45[1] 62-66 (1998)

Chemical stability and aggregation activity of assembly pheromone of argasid ticks and its synthetic purine analogues were studied during long-lasting storage at room temperature as the potential components of attractant/acaricide mixtures. Guanine spherules from dry excreta of Ornithodoros moubata Murray, 1877 were very stable in their chemical composition and did not suffer from purine degradation. However, an intensive purine conversion into uric acid occurred in samples of the fluid of the excreta of Argas persicus (Oken, 1818) and to a lesser extent also in an artificial mixture of synthetic guanine, xanthine and hypoxanthine in saline. The presence...

Investigation of haematophagous arthropods for borreliae - summarized data, 1988-1996

Hubalek Z, Halouzka J, Juricova Z

Folia Parasitologica 45[1] 67-72 (1998)

Blood-sucking arthropods, collected in South Moravia, Czech Republic, were examined by darkfield microscopy for borreliae from 1988 to 1996. Among host-seeking ixodid ticks (8481 Ixodes ricinus (L.), 372 Dermacentor reticulatus (Fabr.), 167 Haemaphysalis concinna Koch), borreliae were only observed in adult (23.2%), nymphal (17.2%) and larval (6.3%) 1. ricinus. The prevalence of borreliae in I. ricinus did not vary considerably among habitats except for lower values in agroecosystems, xerothermic oak woods and grasslands. The frequency of intensity of spirochaetal infection (log(10) counts of borreliae per tick) in I. ricinus approximated the negative...
