Folia Parasitologica 34[1] 1-9 (1987)

In the summer 1976, natural foci of zoonotic cutaneous leishmaniasis were discovered by the authors on the territory of the Mongolian People's Republic. In 1976-1983 the integrated research of these foci was conducted and maps of a structure of the geographical range of the pathogen were compiled taking into account the peculiarities of distribution of its carriers and vectors. Great gerbils are the only identified vertebrate hosts of Leishmania and their infection rate comes up to 100% in single foci. Three species of sandflies belonging to subgenus Paraphlebotomus, Ph. andrejevi, Ph. mongolensis and Ph. alexandri, are vectors of the pathogen in foci....

Malaria in Kampuchea: clinical course of falciparum malaria in Chemin de Fer Hospital, Phnom Penh.

Folia Parasitologica 34[1] 11-18 (1987)

To receive actual information about the clinical course of falciparum malaria case history of 373 patients hospitalized in Chemin de Fer Hospital in Phnom Penh from May 1 till October 1, 1985 were evaluated. No patients were infected in Phnom Penh. We estimated that only 8.3% of patients had higher parasitaemia than 100,000 or more asexual parasites in microliter of peripheral blood which is considered as a heavy infection. Complicated malaria was found in 39 patients (10.4%). The most frequent complications were cerebral complications (80.0%), renal failure (23.3%), and liver failure (16.6%). Ten patients had multiple organ complications and they...

Correlation of the results of IFAT-DASS and ELISA tests in experimental cysticercosis of mice.

L Vánová, S Lukes

Folia Parasitologica 34[1] 25-29 (1987)

The sera of mice experimentally infected with Taenia crassiceps were tested for the occurrence of the antibodies by the enzyme-linked immunosorbent assay (ELISA) and indirect immunofluorescence using defined antigen substrate spheres (IFAT-DASS). Results of both tests were compared. From day 11 p.i. until the end of the experiment (day 108 p.i.) antibodies were detected by both tests. The maximal intensity of the ELISA and IFAT-DASS reactions was observed between days 63 and 94 and days 14 and 46 p.i., respectively. ELISA is an easy-to-do and objectively appraisable method, IFAT-DASS is more suitable for testing antigens weakly adsorbing to polystyrene...

The biology of nematodes of the family Capillariidae Neveu-Lemaire, 1936.

F Moravec, J Prokopic, A V Shlikas

Folia Parasitologica 34[1] 39-56 (1987)

The present knowledge of the life cycles of nematodes of the family Capillariidae is reviewed and these data are considered from the viewpoint of a new system of the classification of genera in this family (Moravec 1982). An analysis of the relevant literature as also own studies have shown that, in this nematode group, there occur both direct (homoxenous) life cycles without an intermediate host (Baruscapillaria, Pseudocapillaria, Calodium, Pseudocapillaroides, partly also Capillaria, Eucoleus and Aonchotheca) and heteroxenous cycles with participation of obligate intermediate hosts that are usually oligochaetes and rarely fishes (Schulmanela, Pearsonema,...

Penetration of ovicidal fungus Verticillium chlamydosporium through the Ascaris lumbricoides egg-shells.

H Lýsek, D Krajcí

Folia Parasitologica 34[1] 57 (1987)

The course of penetration of the ovicidal fungus Verticillium chlamydosporium Goddard through the Ascaris lumbricoides egg-shells was studied in electron miorographs. The contact area between the egg and the fungus is smooth at the stage of the contact of the ovicidal fungus with the egg surface, as well as at the stage of adhesion. No special attaching organs are formed which indicates that no mechanical penetration of the fungal hypha through the egg-shells is involved. Traces of enzymatical activity of the fungus penetrating upright through the egg-shells can be observed during the penetration stage proper. At the consumption stage, the branching...

Bacterial isolation from and transmission by Boophilus decoloratus and Boophilus geigyi.

Folia Parasitologica 34[1] 69-74 (1987)

Bacteria were isolated from the haemolymph of Boophilus decoloratus and Boophilus geigyi which had engorged on trade cattle in Nigeria. All the genera of the bacteria were also isolated from the eggs which they laid although some of them were missing from the larvae which eventually hatched. When clean rabbits were inoculated with some genera of bacteria and clean, laboratory bred larvae of B. decoloratus and B. geigyi fed on them, the same genera of bacteria were subsequently isolated from the haemolymph of the engorged adults, the eggs they produced and the larvae which hatched from them. Staphylococcus pyogenes and Pseudomonas aeruginosa were consistently...

Geographic distribution of Bhanja virus.

Z Hubálek

Folia Parasitologica 34[1] 77-86 (1987)

A review on the geographic distribution, vectors and hosts of Bhanja virus (Bunyaviridae) is based on reports about: isolations of the virus; antibody surveys. Bhanja virus has been isolated in 15 countries of Asia, Africa and Europe, and antibodies against it have been detected in 15 additional countries. Vector range includes ticks of the family Ixodidae (subfam. Amblyomminae; not subfam. Ixodinae): 13 species of 6 genera (Haemaphysalis, Dermacentor, Hyalomma, Amblyomma, Rhipicephalus and Boophilus) yielded the virus. Bhanja virus has only rarely been isolated from vertebrates (Atelerix, Xerus, Ovis, Bos; possibly bats), though antibodies have been...

Folia Parasitologica 34[1] 87-92 (1987)

The efficacy of the drugs flubendazole, levamisole, and their combination was studied against Angiostrongylus cantonensis infection in mice. The drugs were evaluated on day 15 post infection. The efficacy was assessed by using single-dose and 5-dose treatment schedules. Flubendazole was effective at 25 mg/kg, 50 mg/kg, 100 mg/kg, 200 mg/kg when given each day for five days. Levamisole at a dose rate of 200 mg/kg was completely effective in a single treatment. The combined therapy of levamisole (25 mg/kg) and flubendazole (15 mg/kg) produced 100% efficacy. Both drugs given prior to experimental infection showed no prophylactic activity.

Folia Parasitologica 34[1] 93 (1987)

Calcium salts were demonstrated by Kóssa's method in excretory corpuscles of five species of cercariae and six species of metacercariae. The interference of calcium salts in excretory corpuscles in Gomori's method for the detection of alkaline phosphatase is discussed.
