STUDIES ON PROTOZOAN PARASITES OF AUSTRALIAN FISHES .1. NEW SPECIES OF THE GENERA COCCOMYXA LEGER ET HESSE, 1907, ORTHOLINEA SHULMAN, 1962 AND KUDOA MEGLITSCH, 1947 (MYXOZOA, MYXOSPOREA)

Folia Parasitologica 39[4] 289-306 (1992)

Four new myxosporean species are described from marine fishes collected at the New South Wales coast of Australia. Coccomyxa meridiei sp. n. lives in the gall bladder of Herklosichthys castelnaui, and C. tenuiparies sp. n. infects the gall bladder of Heteroclinus whiteleggii. In both species, the polar filaments run at first straight down the polar capsule before forming threads beneath the capsule wall. Ortholinea australis sp. n. infects the hepatic ducts and gall bladder of Acanthopagrus australis and Rhabdosargus sarba. It forms large plasmodia up to 1 mm in size greatly distending the biliary ducts. Kudoa ciliatae sp. n. infects the smooth muscle...

BIOMETRIC VARIABILITY OF PROTEOCEPHALUS-NEGLECTUS (CESTODA, PROTEOCEPHALIDAE) IN 2 DIFFERENT AGE-GROUPS OF THE RAINBOW-TROUT FROM THE DOBSINA WATER RESERVOIR (EAST SLOVAKIA)

Folia Parasitologica 39[4] 307-316 (1992)

The variability of 24 morphological characteristics in Proteocephalus neglectus La Rue, 1911, a parasite of the rainbow trout (Oncorhynchus mykiss (Walbaum)) was studied. Specimens of two morphologically clearly distinguishable types formed the metapopulation (hostophenote) of P. neglectus. The cestodes from type A (isolated from smaller, younger fish) were mostly no longer than 50 mm, the mature and gravid segments in almost all of them were more long than wide, contained small number of larger testes and an ovary with wide elliptic lobes. The cestodes from type B (isolated from larger, older fish) tended to be more than 50 mm long: the typical segment...

REDESCRIPTION OF PROTEOCEPHALUS-NEGLECTUS LA-RUE, 1911 (CESTODA, PROTEOCEPHALIDAE), A TROUT PARASITE, INCLUDING DESIGNATION OF ITS LECTOTYPE

HANZELOVA V, SCHOLZ T

Folia Parasitologica 39[4] 317-323 (1992)

The tapeworm Proteocephalus neglectus La Rue, 1911 (Cestoda: Proteocephalidae), a common trout parasite in Europe, is redescribed on the basis of type specimens, comparative material from two different hosts (Salmo trutta m. fario and Oncorhynchus mykiss) and several geographical regions as well as on the literary data. The lectotype of this species is designated and the problem of the validity of Proteocephalus species parasitizing salmonid fish is briefly discussed.

MORAVEC F, KOHN A, FERNANDES BMM

Folia Parasitologica 39[4] 327-353 (1992)

The present paper comprises a systematic survey of nematodes of the superfamilies Trichuroidea, Oxyuroidea and Cosmocercoidea collected from fishes of the Parana River, southern Brazil, in 1985 and 1991. The following species were recorded: Paracapillaria piscicola. Capillariidae gen. sp. 1, Capillariidae gen. sp. 2, Travnema travnema, T. araujoi, Cosmoxynema vianai, Cosmoxynemoides aguirrei, Ichthyouris laterifilamenta sp. n., I. brasiliensis, Brasilnema pimelodellae, Parasynodontisia petterae and Rondonia rondoni. I. lateristriga sp. n. from Trachydoras paraguayensis is characterized mainly by the presence of lateral egg filaments and by the structure...

A SCANNING ELECTRON-MICROSCOPE STUDY OF TOXOCARA-GENETTAE WARREN, 1972 (ASCARIDAE), WITH DATA ON MORPHOMETRIC VARIATION

Folia Parasitologica 39[4] 355-367 (1992)

We have carried out a morphometric study of the ascaridoid nematode Toxocara genettae, parasite of the small intestine of the genet Genetta genetta, with the aid of scanning electron microscopy (SEM). Host specimens were trapped in Galicia, NW Spain. The most characteristic features of this nematode are the absence of cervical alae, replaced by narrow lateral crests running along the length of the body and the presence of a mucron at the end of the male tail. Other features of interest include the number of labial denticles (90-98 and 96-102 on the dorsal lip, 82 96 and 90-96 on the subventral lip of male and female, respectively), the width of the...

STRONGYLOIDES-OPHIUSENSIS SP-N (NEMATODA, STRONGYLOIDIDAE), PARASITE OF AN INSULAR LIZARD, PODARCIS-PITYUSENSIS (SAURIA, LACERTIDAE)

ROCA V, HORNERO MJ

Folia Parasitologica 39[4] 369-373 (1992)

The parasitic female of the nematode Strongyloides ophiusensis sp. n.. fund in the intestine of lizard Podarcis pityusensis (Bosca, 1883) from Balearic Islands (West Mediterranean), is described. This species differs from other similar Strongyloides species in the body size, the morphology of the stoma, the structure of the ovaries and in the stage of development of the eggs, and also in some ecological and chorological characters.

IMMUNIZATION OF RABBITS WITH ANTIGENS FROM PSOROPTES-CUNICULI, THE RABBIT SCAB MITE

UHLIR J

Folia Parasitologica 39[4] 375-382 (1992)

Rabbits immunized with the whole body extract of Psoroptes cuniculi (Delafond, 1859) developed partial immunity to the infestation with this mite. These rabbits manifested P cuniculi antigen-induced cell response and a high level of specific serum antibody after the immunization. Electrophoretic separation of the mite extract followed by immunostaining with various sera revealed differences between artificially immunized and naturally infested rabbits to most of the P cuniculi antigens. However, the specific antibody pattern, that was developed by the immunized rabbits, was not changed after these rabbits were infested with the mites.

AN EXPERIMENTAL TRANSMISSION OF PORCINE STRAINS OF BLASTOCYSTIS SP IN THE LABORATORY MICE AND GERBILS

PAKANDL M

Folia Parasitologica 39[4] 383-386 (1992)

Outbred laboratory mice were successfully infected with porcine strains of Blastocystis sp. using faecal stages as well as stages from fresh or passaged cultures. In contrast, inbred BALB/c mice and gerbils were only rarely infected and the intensity of their infection was mostly negligible. Blastocystis sp. was never observed inside the host cells. These results indicate a low host specifity of Blastocystis sp. as well as different sensitivity of investigated hosts to Blastocystis sp. infection.

INHIBITION OF PROLIFERATION OF TUMOR-CELL CULTURES BY BIOLOGICALLY-ACTIVE SUBSTANCES ISOLATED FROM THE TISSUES OF FASCIOLA-HEPATICA AND FASCIOLA-HEPATICA-INFECTED RAT-LIVER

TSOCHEVA N, TOSHKOVA R, FILCHEV A

Folia Parasitologica 39[4] 387-390 (1992)

Biologically active substances (BAS) were isolated from the tissues of Fasciola hepatica L. and from F. hepatica-infected rat liver by ethanol precipitation from aqueous tissue homogenates. A marked inhibiting effect of the newly isolated BAS on hepatoma MC29 cell culture proliferation and a slight inhibiting effect of the newly isolated BAS on myeloma cell culture proliferation was found. The strongest inhibiting effect was by BAS isolated from the tissues of F. hepatica. The inhibiting effect of the BAS isolated from F. hepatica-infected liver was stronger than the effect of the BAS isolated from normal liver tissue.

GYRODACTYLUS-BOHEMICUS SP-N (MONOGENEA, GYRODACTYLIDAE) FROM ONCORHYNCHUS-MYKISS (WALBAUM) AND SALVELINUS-FONTINALIS (MITCHILL) (CLUPEIFORMES, SALMONIDAE) IN CZECHOSLOVAKIA

ERGENS R

Folia Parasitologica 39[4] 391-394 (1992)

Gyrodactylus bohemicus sp. n. (Gyrodactylidae: Monogenea) is described from the fins, skin and gill filaments of Oncorhynchus mykiss (Walbaum) and Salvelinus fontinalis (Mitchill) (Clupeiformes: Salmonidae) from a trout farm in Czechoslovakia. G. bohemicus sp. n. is most closely related to G. thymalli Zitnan, 1960 and G. magnus Konovalov, 1967 in the shape of the anchors, the ventral and the dorsal bar, but can be distinguished from both these species by the shape of the marginal hook proper.

2 NEW SPECIES OF THE GENUS GYRODACTYLUS NORDMANN, 1832 (MONOGENEA, GYRODACTYLIDAE) FROM ESOMUS-LONGIMANA (LUNEL) (CYPRINIFORMES, CYPRINIDAE) IN LAOS

ERGENS R, SCHOLZ T

Folia Parasitologica 39[4] 395-398 (1992)

Two new species of Gyrodactylus, G. esomi sp. n. and G. kottelati sp. n. are described from Esomus longimana (Lunel) caught in the Vientiane Province, Laos. G. esomi sp. n. differs from its nearest relative G. gnathopogonis Ergens et Gussev, 1975 by the smaller size of the anchors and a different shape of the marginal hooks. G. seravschani Osmanov, 1965 and G. sprostonae Ling Mo-en, 1962 are the closest apparent relatives of G. kottelati sp. n. but differ from this species principally in the shape of the marginal hook proper and the shape of the ventral bar shield.
