Soricimyxum fegati gen. et sp. n. is a new myxosporean (Myxozoa) species discovered in the liver of shrews, Sorex araneus L., collected in the Bialowieza primeval forest (Poland). Both developmental stages and mature spores were found during a histological study. The infection had about 40% prevalence at the investigated locality. Plasmodia were polysporic. Elongated plasmodia with an average size of 30 by 8 µm occupied bile ducts and larger rounded plasmodia up to 80 µm in diameter were found in liver parenchyma where they most probably entered after the ducts had been destructed. Plasmodia in both locations elicited a vigorous...

Folia Parasitologica 54[3] 165-171 (2007) | 10.14411/fp.2007.023

The first ultrastructural description of Ceratomyxa tenuispora Kabata, 1960 (Myxozoa, Bivalvulida) from Madeira Island (Portugal), a parasite found in the gall bladder of the commercially important black-scabbard fish, Aphanopus carbo Lowe is presented. This parasite possesses spherical to ellipsoidal disporous trophozoites. Spores have a central crescent-shaped body averaging 11.0 µm in length, 28.5 µm in thickness and 12.1 µm in width. The valves have two long opposite lateral processes (ribbon-like structures or tails), each averaging 173 µm in length. The total thickness of the spore averages 375 µm....

Experimental activation of peritoneal macrophages by interferon gamma (IFN-γ) resulted in the inhibition of Encephalitozoon cuniculi replication. However, E. cuniculi could replicate either in a non-activated cell line of murine macrophages PMJ2-R or in IFN-γ-activated PMJ2-R cells. Moreover, activation with IFN-γ led to faster replication of E. cuniculi in these cells. Opsonisation of E. cuniculi spores with anti-E. cuniculi polyclonal antibody did not affect E. cuniculi replication in both, non-activated and activated murine macrophages. In contrast, opsonisation of E. cuniculi spores...

Folia Parasitologica 54[3] 177-190 (2007) | 10.14411/fp.2007.025

Five new species of Potamotrygonocotyle (Monocotylidae) are described and Paraheteronchocotyle amazonense Mayes, Brooks et Thorson, 1981 (Hexabothriidae) is redescribed from monogenoideans collected on the gills of species of Potamotrygonidae from the Negro River, Amazon, Brazil. Potamotrygonocotyle quadracotyle sp. n. and P. umbella sp. n. were found parasitizing an undescribed species of Potamotrygon; Potamotrygonocotyle rarum sp. n. is described from Potamotrygon schroederi; Potamotrygonocotyle rionegrense inhabits Potamotrygon cf. motoro; Potamotrygonocotyle aramasae sp....

Three species of Calydiscoides (Monogenea: Diplectanidae) from five Lethrinus spp. (Lethrinidae: Perciformes) off New Caledonia, with a description of Calydiscoides terpsichore sp. n.

Guilhem Rascalou, Jean-Lou Justine

Folia Parasitologica 54[3] 191-202 (2007) | 10.14411/fp.2007.026

Numerous specimens of Calydiscoides spp. from Lethrinus nebulosus and L. harak, and fewer specimens from L. lentjan, L. ravus and L. obsoletus, collected off New Caledonia, South Pacific, were examined. Three species of Calydiscoides were recognized. Calydiscoides difficilis (Yamaguti, 1953) Young, 1969 was generally the most abundant species on the five hosts. Specimens of C. difficilis were measured and compared to the type specimens (from Indonesia) and museum vouchers (from Australia and the Arabian Gulf). The morphology of the massive male copulatory organ and of haptoral sclerotized...

Haliotrema banana sp. n. (Monogenea: Ancyrocephalidae) from Bodianus perditio (Perciformes: Labridae) off New Caledonia

L.H.S. Lim, Jean-Lou Justine

Folia Parasitologica 54[3] 203-207 (2007) | 10.14411/fp.2007.027

Sixteen labrid species, including four Bodianus spp., were examined in New Caledonia (South Pacific) and monogeneans were found only on Bodianus perditio (Quoy et Gaimard). This species, Haliotrema banana sp. n., is the second Haliotrema species to be described from the labrids, the first being Haliotrema bodiani Yamaguti, 1968 from Bodianus albotaeniatus (Valenciennes), previously designated as B. bilunulatus (Lacépède). The new species is similar to H. bodiani in soft reproductive parts but differs from it in the morphologies of the hard haptoral parts, mainly in the shape of the dorsal...

Folia Parasitologica 54[3] 208-214 (2007) | 10.14411/fp.2007.028

Specimens of the elasmobranch, Isurus oxyrinchus Rafinesque, captured in 1999 in the state of Santa Catarina, Brazil, were parasitized with the poecilacanthoid trypanorhynch cestode Gymnorhynchus isuri Robinson, 1959, that is redescribed here. New details of scolex and proglottid morphology are given. These details are mainly related to tentacle armature, terminal genitalia and observations of external morphology of proglottids.

Folia Parasitologica 54[3] 215-219 (2007) | 10.14411/fp.2007.029

A new nematode species, Spirophilometra pacifica sp. n. (Philometridae), is described from gravid female specimens collected from the mouth cavity (the upper palate) of the fish (yellow snook) Centropomus robalito (Centropomidae, Perciformes) from the Chantuto-Panzacola system, Chiapas, in the Pacific coast of Mexico. Its morphology is very similar to that of the species originally described as Philometra centropomi Caballero, 1974, but the gravid females of S. pacifica are about three times longer (body length 11.63-18.17 mm); host species and the geographical distribution of both these forms also differ. Scanning electron...

Cucullanus pargi sp. n. (Nematoda: Cucullanidae) from the grey snapper Lutjanus griseus off the southern coast of Quintana Roo, Mexico

Folia Parasitologica 54[3] 220-224 (2007) | 10.14411/fp.2007.030

A new nematode species, Cucullanus pargi sp. n., is described from the intestine and pyloric caeca of the grey snapper, Lutjanus griseus (Linnaeus), off the southern Quintana Roo coast, Mexico. This species shows similar morphological features as cucullanids occurring in marine and brackish-water fishes; however, it differs from all other species in the length of spicules, arrangement and number of caudal papillae, position of the excretory pore and deirids. Cucullanus pargi is the third species of this genus described from fishes in Mexico and the second one from Mexican marine fishes.

Endoparasitic mites of the genus Endotrombicula Ewing, 1931 (Acari: Prostigmata: Parasitengona: Trombiculidae) from African and Madagascan anurans, with description of a new species

Folia Parasitologica 54[3] 225-235 (2007) | 10.14411/fp.2007.031

A sample of over 6,000 specimens of frogs belonging to about 120 species of all families occurring in West Africa and Madagascar were screened for parasitic mites. Three species of Endotrombicula Ewing, 1931 were found in representatives of two African and two Madagascan frog families. All Trombiculidae found in African frogs belonged to Endotrombicula pillersi (Sambon, 1928), whereas in Madagascar E. madagascariensis (Sambon, 1928) and E. ptychadenae sp. n. were sampled. These three species are described, data about their parasitic associations are provided, and their zoogeographical distribution is discussed. Only those...

First experimental observations on the development of Rhabdochona denudata (Nematoda: Rhabdochonidae) in the intermediate host

Franti¹ek Moravec

Folia Parasitologica 54[3] 236-238 (2007) | 10.14411/fp.2007.032

Two species of mayfly nymphs, Habroleptoides modesta (Hagen) and Habrophlebia lauta (Eaton) (Ephemeroptera: Leptophlebiidae), were found as suitable experimental intermediate hosts of the fish nematode Rhabdochona denudata (Dujardin, 1845) (Rhabdochonidae), an intestinal parasite of Palaearctic cyprinids. The parasite's eggs were obtained from nematode gravid females parasitizing the European chub, Leuciscus cephalus (L.), of the Rokytná River, Czech Republic. At the water temperature of 9°C, the eggs of R. denudata were ingested by the intermediate host and the hatched, toothed (with a minute cephalic boring tooth)...
