A total of 1288 hamsters (Cricetus cricetus), coming from two regions of Czechoslovakia, were serologically investigated on the presence of leptospirosis. In 1114 hamsters from eastern Slovakia, where an outbreak occurred and local populations lived quite atypically, there was 31.8% positivity, in 174 animals from central Moravia, where the populations were at higher levels but lived normally, the positivity amounted to 17.2%. The serological positivity increases proportionately to the weight, i.e. to the age of the animals. The serovar grippotyphosa was dominant in them (29.6% of examined hamsters), while 6.0% were positive for L. pomona, 1.0% for...

Comparative studies on the morphology, histology, and histochemistry of metacestodes (Hymenolepididae, Dilepididae and Dipylidiidae).

J Valkounová

Folia Parasitologica 34[2] 117-128 (1987)

Histological and histochemical methods were used for the studies on 12 species of metacestodes of the genera Coronacanthus, Diorchis, Diplopylidium, Fimbriaria, Hymenolepis, Microsomacanthus, Rodentotaenia, and Triodontolepis. Two basic types of larvae, cysticercoid and cercoscolex, were found. The cyst structure is identical or similar in the cysticercoids using the same group of intermediate hosts (gammarus, planktonic crustaceans, coprophagous beetles, and terrestrial snails). The morphological structure of scolex and neck is the same as in adult cestodes. The length and number of hooks are definitive in morphologically differentiated metacestodes,...

Malic enzyme, malate dehydrogenase, fumarate reductase and succinate dehydrogenase in the larvae of Taenia crassiceps (Zeder, 1800).

J Zenka, J Prokopic

Folia Parasitologica 34[2] 131-136 (1987)

Malate dehydrogenase, malic enzyme, succinate dehydrogenase, and fumarate reductase activities have been studied in the cytoplasm and mitochondria of Taenia crassiceps larvae. The results show that these larvae contain enzymes for anaerobic acquisition of energy with terminal fumarate reductase, but some facts, as the high ratio of succinate dehydrogenase activity to fumarate reductase activity and the low proportion of fumarate reductase in the whole NADH oxidase activity in mitochondria, suggest that aerobic processes are also involved in the energy acquisition in this parasite.

Occurrence of Phyllodistomum umblae (Fabricius, 1780) in the ureters of coregonids of Lake Yli-Kitka in northeastern Finland.

R Rahkonen, E T Valtonen

Folia Parasitologica 34[2] 145-155 (1987)

380 whitefish (Coregonus sp.) and 260 vendace (Coregonus albula L.) were studied from Lake Yli-Kitka in northeastern Finland during 1980-1982. 33% of the whitefish and 38.5% of the vendace were infected with Phyllodistomum umblae (Fabricius, 1780), the average intensity of infection being 4.2 and 2.3 per infected fish, respectively. No clear seasonality was observed in either the prevalence and intensity of infection or in the level of maturation and the length of P. umblae in both fish species, which points to a continuous invasion and maturation of these trematodes. The prevalence and intensity of P. umblae infection was highest in the middle-sized...

Capillostrongyloides Ancistri sp. n. (Nematoda: Capillariidae) a new pathogenic parasite of aquarium fishes in Europe.

F Moravec, M Gelnar, J Rehulka

Folia Parasitologica 34[2] 157 (1987)

A new nematode species, Capillostrongyloides ancistri sp. n., is described from the intestine of aquarium-reared catfish Ancistrus dolichopterus Kner in Czechoslovakia. This fish is of South American origin and, therefore, C. ancistri sp. n. has probably been brought into aquaria in Europe from there. The parasite is characterized mainly by the structure of the male caudal end (presence of two large postanal papillae and the cuticular bursa supported by two caudal lobes), the length of a spicule (0.258-0.297 mm), the presence of a non-spiny spicular sheath, shape of the female end, structure of the stichosome (23-30 stichocytes present), and the size...

Demodex kutzeri sp. n. (Acari: Demodicidae), an identical parasite of two species of deer, Cervus elaphus and C. nippon pseudaxis.

V Bukva

Folia Parasitologica 34[2] 173 (1987)

Reports on demodicid mites of the old world species of deer are reviewed and Demodex kutzeri sp. n. (= D. cervi sensu Kutzer and Grünberg 1972; part.) described in all stages of the life cycle. The occurrence of D. kutzeri on two host species, Cervus elaphus L., 1758 and C. nippon pseudaxis Eydoux et Souleyet, 1841 is reported and discussed as a rare phenomenon in the genus Demodex.

Folia Parasitologica 34[2] 189-191 (1987)

Two squirrels aged 16 weeks and three muskrats aged 24 weeks were subcutaneously infected with a dose of 400 SMicLD50 of the extraneurally passaged "236" strain of Tahyna virus. Viremia was detected in one squirrel (48 and 96 hours post infection) and in two muskrats (24 and 48 hours p.i.). Seroconversion was demonstrated by plaque-reduction neutralization test (PRNT) 21 days p.i. in all animals.
