Folia Parasitologica 48[4] 249-254 (2001) | DOI: 10.14411/fp.2001.041

An experimental infection with the microsporidian Encephalitozoon cuniculi Levaditi, Nicolau et Schoen, 1923 was studied using a model of immunocompetent BALB/c mice and immunodeficient SCID mice. The course of infection after intraperitoneal inoculation of E. cuniculi spores was evaluated using the presence of spores in peritoneal macrophages as a criterion. First significant decrease in the proportion of infected cells was recorded on day 9 post infection (p.i.) in BALB/c mice. From day 14 p.i. no spores were observed in macrophages from BALB/c mice, while the number of infected macrophages from SCID mice increased until the death of...

Ultrastructure of developmental stages of Hemolivia mariae (Apicomplexa: Haemogregarinidae), natural parasite of the Australian sleepy lizard, in experimentally infected deviant hosts

Ilan Paperna, Catherine J. Smallridge

Folia Parasitologica 48[4] 255-262 (2001) | DOI: 10.14411/fp.2001.042

Mabuya vitatta (Olivier) (Scincidae) and Agama stellio (L.) (Agamidae) were infected with Hemolivia mariae Smallridge et Paperna, 1997 by ingestion of tick viscera from Amblyomma limbatum Neumann, fed as nymphs on naturally infected Australian sleepy lizards, Tiliqua rugosa Gray. The unnatural infection apparently interfered with the developmental schedule of the parasites. Transmission electron microscopic images of merogonic stages were obtained, as well as images of early developing gametocytes. Tissue and intraerythrocytic meronts were bound by a hardened wall. Intraerythrocytic gametocytes were lodged in a parasitophorous...

Haemogregarines of the genus Hepatozoon (Apicomplexa: Adeleina) in rodents from northern Europe

Folia Parasitologica 48[4] 263-267 (2001) | DOI: 10.14411/fp.2001.043

We studied the prevalence and distribution of Hepatozoon infections in small rodents from Finland and other areas in northern Europe. Hepatozoon infections were more common in voles (Arvicolinae) than mice (Murinae) and more prevalent in voles of the genus Clethrionomys than in voles of the genus Microtus. Transmission electron microscopical examination of Hepatozoon erhardovae Krampitz, 1964 from bank voles Clethrionomys glareolus (Schreber) showed that intracellular lung meronts were located in alveolar septa. Meronts consisted of varying numbers of merozoites packed with amylopectin vacuoles inside electron-lucent...

Potential impacts of clearcutting on parasites of minnows in small boreal lakes

David J. Marcogliese, Mark Ball, Murray W. Lankester

Folia Parasitologica 48[4] 269-274 (2001) | DOI: 10.14411/fp.2001.045

Clearcutting and deforestation lead to increased erosion, increased water temperature, altered water chemistry, and modified watershed hydrology in aquatic systems. Effects on biological organisms have been documented for phytoplankton, zooplankton, benthos, and fish. In this study, parasites of the northern redbelly dace, Phoxinus eos (Cope), were examined from an experimental area consisting of headwater lakes and their watersheds in the boreal forest of Ontario, Canada prior to and after clearcutting around the lakes. Catchments of two lakes were heavily, and one lake partially, clearcut in 1996, and that of a fourth lake was untouched. In...

Caryophyllidean tapeworms (Platyhelminthes: Eucestoda) from freshwater fishes in Japan

Tomáš Scholz, Takeshi Shimazu, Peter D. Olson, Kazuya Nagasawa

Folia Parasitologica 48[4] 275-288 (2001) | DOI: 10.14411/fp.2001.046

The following caryophyllidean tapeworms were found in freshwater fishes from Japan (species reported from Japan for the first time marked with an asterisk): family Caryophyllaeidae: Paracaryophyllaeus gotoi (Motomura, 1927) from Misgurnus anguillicaudatus (Cantor); Archigetes sieboldi Leuckart, 1878 from Pseudorasbora parva (Temminck et Schlegel) and Sarcocheilichthys variegatus microoculus Mori (new hosts); family Lytocestidae: *Caryophyllaeides ergensi Scholz, 1990 from Tribolodon hakuensis (Günther), T. ezoe Okada et Ikeda, Hemibarbus barbus (Temminck et Schlegel) and Chaenogobius...

The status of the Diplosentidae (Acanthocephala: Palaeacanthocephala) and a new family of acanthocephalans from Australian wrasses (Pisces: Labridae)

Sylvie Pichelin, Thomas H. Cribb

Folia Parasitologica 48[4] 289-303 (2001) | DOI: 10.14411/fp.2001.047

The status and composition of the Diplosentidae Tubangui et Masiluñgan, 1937 are reviewed. The type species of the type genus, Diplosentis amphacanthi Tubangui et Masiluñgan, 1937 from Siganus canaliculatus (Park, 1797) in the Philippines, is concluded to have been described inaccurately in supposedly possessing only two cement glands and lemnisci enclosed in a membranous sac. The species is almost certainly very close to species of Neorhadinorhynchus Yamaguti, 1939 and Sclerocollum Schmidt et Paperna, 1978 which have also been reported from siganids from the tropical Indo-Pacific. Species of these genera have...

The life cycle of Dichelyne (Cucullanellus) minutus (Nematoda: Cucullanidae)

Marianne Køie

Folia Parasitologica 48[4] 304-310 (2001) | DOI: 10.14411/fp.2001.048

Mature specimens of the nematode Dichelyne (Cucullanellus) minutus (Rudolphi, 1819) (Ascaridida, Cucullanidae, Seuratoidea) were obtained from the intestine of flounder Platichthys flesus (L.) caught in the Øresund, Denmark. Plaice Pleuronectes platessa L. and common goby Pomatoschistus microps (Kröyer) also harbour this species. The eggs embryonate on the seabottom. Larvae about 440 µm long, and believed to be in their third stage, hatch from the eggs. These larvae are not directly infective to flounders or gobies. The polychaete Nereis diversicolor O.F. Müller acts as obligatory intermediate...

New oxyuroid nematodes of the genera Ichthyouris and Spinoxyuris from South American freshwater fishes

František Moravec, Vernon E. Thatcher

Folia Parasitologica 48[4] 311-320 (2001) | DOI: 10.14411/fp.2001.049

Three hitherto unknown oxyuroid nematode species of the family Pharyngodonidae are described from the intestine of South American freshwater fishes, two of them being established as species new to science: Spinoxyuris annulata sp. n. from Myleus ternetzi (Norman) (Serrasalmidae) from French Guiana (Sinnamary River) and Ichthyouris ovifilamentosa sp. n. from Cichlasoma sp. (Cichlidae) from Amazonas (Negro River, São Gabriel da Cachoeira), Brazil. A third species, recovered from the same host as the latter (Cichlasoma sp.), was identified only as Ichthyouris sp. because of the absence of the male, although...

Two new species of the family Syringophilidae (Acari: Cheyletoidea) from passeriform birds collected in the Altai

Andre Bochkov, Dmitry Apanaskevich

Folia Parasitologica 48[4] 321-325 (2001) | DOI: 10.14411/fp.2001.050

Two new species of the syringophilid mites (Acari: Syringophilidae) are described from quills of passeriform birds. Syringophilopsis faini sp. n. is described from Sylvia curruca (L.) (Sylviidae) and Syringophiloidus carpodaci sp. n. is described from Carpodacus erythrinus (Pall.) (Fringillidae). Characters are detailed that differentiate Syringophilopsis faini from three species of a new "turdus" group, and Syringophiloidus carpodaci from S. minor.
