Intravenous infection of mice with Naegleria fowleri.

R G May, D T John

Folia Parasitologica 29[3] 201 (1982)

Naegleria fowleri produced fatal meningoencephalitis in mice following intravenous (i.v.) inoculation. Amebae were present in the peripheral circulation for 120 minutes after i.v. inoculation with a dose of 10(7) trophozoites per mouse. Amebae were cultured from and observed in brain (days 1-21), lung (days 1-12), and liver and kidney (days 1-5). Infected mice exhibited weight loss, leukocytosis, reduced lymphocyte/neutrophil ratio, neurologic symptoms, and mortality. Histologically, the disease was characterized by an acute, hemorrhagic, necrotizing meningoencephalitis. Although amebae were detected in tissues other than brain, pathologic involvement...

Naegleria fowleri in thermally polluted waters).

Folia Parasitologica 29[3] 211-218 (1982)

Two complexes of lakes and canals supplying water for two electric power plants, their steam condensors and an adjoining river were investigated by means of culture methods for the presence of Naegleria fowleri in Poland in the period from 1974 to 1980. Sixty-four strains of N. fowleri were isolated, 13 isolates being virulent for mice when instilled intranasally. These strains were found in the steam condensor of the power station A and in waters polluted with warm water of this plant. Pathogenic N. fowleri strains occurred also in an adjoining river connected with the water system of the power plant. The results show the possible role of the steam...

Indirect haemagglutination reaction with Sarcocystis dispersa antigen.

L Cerva, Z Cerná

Folia Parasitologica 29[3] 219-225 (1982)

A description is given of the preparation of antigen from Sarcocystis dispersa cystozoites and the procedure of the indirect haemagglutination test (IHA). The antibodies against this antigen were detected in experimentally infected mice from day 20 p.i. (1: 640). In the following weeks the antibody titres reached the value of 1: 40,960. The sera of pigs, sheep and horses spontaneously infected with other Sarcocystis species reacted with this antigen in low titres only. The bovine sera gave negative reactions even in cases when Sarcocystis cysts were present in the muscles of the examined animals. A possible application of IHA for the research and diagnostic...

The migration of larvae of Toxascaris leonina (Linstow, 1909) in experimentally infected white mice.

J Prokopic, V Figallová

Folia Parasitologica 29[3] 233 (1982)

The migration of larvae of Toxascaris leonina was studied in 168 white mice. The larvae were found in lungs of 96% of infected mice on days 4-135, in genital organs (84%), intestinal mucosa (81%) and skeletal muscles (100%) on day 10 post infection. The maximum number of larvae were detected in intercostal muscles on day 105 post infection.

Folia Parasitologica 29[3] 253 (1982)

A total of 110 bulls coming from a farm where cysticercosis repeatedly occurred were examined by means of indirect haemagglutination (IHA), microprecipitation in agar (MPA), and indirect immunofluorescence reaction (IFR). Cysticercosis (isolated cysts with live or dead cysticerci) was detected in 29 of them at post-mortem examination. Among the 29 infected animals, positive reactions were obtained in 37.9% with IHA, 51.7% with MPA and 10.3% with IFR. The remaining animals were negative. Of 82 animals giving negative reactions with IHA, 22% harboured cysticerci at post-mortem examination. Of 70 animals negative with MPA, 20% were infected with cysticerci...

In vitro estimation of glycogen content in three sheep cestodes.

S Tayal, G Premvati

Folia Parasitologica 29[3] 259-263 (1982)

The glycogen content (fresh weight) was biochemically estimated in immature, mature and gravid proglottids of three cestodes, Avitellina centripunctata (Rivolta, 1874), Stilesia globipunctata (Rivolta, 1874) and Moniezia expansa (Rudolphi, 1910), having different niche in the small intestine of sheep. The glycogen gradient was in the order of mature greater than immature greater than gravid proglottids of each species of cestode. Maximum glycogen content was found to be in M. expansa and it was physiologically correlated with the presence of carbon dioxide in the posterior region of the intestine.

Ovicidal fungi in soils of Cuba.

H Lýsek, O Fassatiová, N Cuervo Pineda, N Lorenzo Hernández

Folia Parasitologica 29[3] 265-270 (1982)

Thirty-six strains of ovicidal fungi were isolated from 122 investigated soil samples collected in Cuba. The isolated strains belong to 8 genera, 2 strains consist of sterile mycelium only. Most of the strains belong to the genus Fusarium (4 species, 1 undetermined strain), the remaining ones to Mortierella (3 species and 6 undetermined strains), Humicola (2 species), Paecilomyces (2 species) and Penicillium (2 species). The genera Verticillium, Gliocladium and Cunninghamella were represented by one species each. A majority of isolated strains exhibited a high to very high ovicidal activity immediately after isolation; strains with a lower initial...

Antifungal activity of pyrithione against Emmonsia crescens in vitro and in vivo.

A Tomsíková, J Sterba, J Prokopic, D Novácková

Folia Parasitologica 29[3] 271-278 (1982)

The sensitivity of saprophytic and parasitic phase of some strains of Emmonsia crescens, E. parva and Chrysosporium pannorum to 22 antimycotic drugs was studied in vitro. Pyrithione produced the best effect on both live phases of the studied strains. The efficacy of Pyrithione, Pimafucin and Amphotericin B was compared in experimental adiaspiromycosis, Pyrithione showed also in vivo the best therapeutic effect. It depended on the beginning of the application. The illness did not develop if Pyrithione was applied during the first 15 days after the infection. In case of later application of Pyrithione only a very light form of adiaspiromycosis developed....

Folia Parasitologica 29[3] 279-284 (1982)

The problems associated with infections by dermatophytes and related fungi are discussed. Published and unpublished surveys of 1 481 wild animals of the orders Carnivora, Ungulata, Lagomorpha, Rodentia, Insectivora and Chiroptera and of 29 birds proved to be positive for fungi which were classified as potentially pathogenic zoophilic, potentially pathogenic geophilic and normally non-pathogenic geophilic. Trichophyton mentagrophytes var. mentagrophytes was isolated from 11% of rodents; the fungus was also isolated from Insectivora, the hare and the ibex. T. mentagrophytes var. erinacei was reported in the hedgehog. Microsporum canis was reported in...
