Pathology of the migration phase of Taenia hydatigena (Pallas, 1766) larvae.

The pathological picture of the migration phase of C. tenuicollis in pigs is characterized by a haemorrhagia within the liver parenchyma and under the liver surface. The haemorrhagia, which represents a migrational canal, is induced by the destruction of liver sinuses by migrating larvae. Approximately on day 10 p.i. a serofibrinous peritonitis occurs and free cysticerci appear in the exudate. On days 14-16 p.i. the exudative peritonitis may increase. The cysticerci are localized under the serosas or on them. On about day 10 p.i. even the pulmonary form of the disease may occur. On day 13 p.i. the cysticerci are present in the lumen of lung arteries...

Chalone-like inhibition of DNA synthesis in helminths.

K Kudrna, J Prokopic

Folia Parasitologica 32[2] 145-149 (1985)

Chalone-like inhibitory activity was found in extracts from tissues of Taenia crassiceps cysticercus and tissues of adult Ascaris suum. The inhibitory effects were partially species nonspecific: The extracts from T. crassiceps larvae inhibit both T. crassiceps and Mesocestoides corti larvae DNA synthesis. Extracts from A. suum, however, inhibit only T. crassiceps. Besides them, the inhibitory factor from mouse brain inhibits both T. crassiceps and M. corti DNA synthesis. When the inhibitory factor from A. suum was applied 4 times during 24-hr culture (at 6-hr intervals), the inhibitory effect was decreased.

Identity of Argas (Argas) polonicus populations in Czechoslovakia and Poland.

F Dusbábek

Folia Parasitologica 32[2] 163 (1985)

The author made a morphological and biological comparison between the population of Argas (A.) polonicus Siuda, Hoogstraal, Clifford et Wassef, 1979 from Poland and the population of that species from Czechoslovakia, denoted in previous author's papers as Argas (A.) vulgaris Filippova, 1961. The comparison of morphometric features as well as the results obtained in the studies of those argasids in SEM have demonstrated some statistically significant differences which the author evaluates as intraspecific adaptive variability and does not attach any taxonomic importance to them. Experimental hybridization of P1 and F1 generations in both populations...

Rickettsiae in the Sumava region.

Folia Parasitologica 32[2] 173-183 (1985)

Antibodies were detected to C oxiella burnetii, Rickettsia slovaca and Chlamydia psittaci in the blood of small terrestrial mammals, larger wild and domestic animals and humans in the southern part of the Protected Landscape Area of the Sumava region between 1977 and 1982. The data obtained have contributed to the safe development of livestock raising in this region.

Changes in ascorbic acid content in various organs and serum of mice experimentally infected with Taenia crassiceps (Zeder, 1800) cysticerci.

E Strnadová, J Prokopic

Folia Parasitologica 32[2] 185-188 (1985)

It was demonstrated that helmith infection affects the ascorbic acid content in various tissues of experimental mice. The level of vitamin C in the mouse liver, kidneys, spleen and serum decreases after infection with T. crassiceps. Maximum decrease in blood serum was observed on day 7 p.i. at the intensity of infection 15 and 30 cysticerci per mouse. There was a correlation between the intensity of infection and decrease in the ascorbic acid level in the spleen.

Penetration of ovicidal fungi through altered egg-shells of Ascaris suum.

V Chalupová, D Solcová

Folia Parasitologica 32[2] 189-192 (1985)

Ovicidal activity was studied in microscopic fungi penetrating into and destroying eggs of geohelminths surviving in the soil. The character of penetration was compared in eggs obtained mechanically with those obtained by means of a chemical process. A total of 13 strains of ovicidal fungi of 4 species were studied. The shells of eggs obtained by the chemical process were so altered that under the same conditions they were attacked and penetrated by the fungi much more than the eggs obtained by a mechanical way. The advantages and disadvantages of these two methods of eggs isolation are discussed.
