Congenital toxoplasmosis in premature twins.

Folia Parasitologica 33 1-6 (1986)
In the course of the study "Toxoplasmosis and Prematurity" 330 blood samples from twins were examined. Our findings in a series of 21 premature twins (maternal sera were also examined) are reported in this paper. Toxoplasma antibodies were detected by the Sabin-Feldman test and specific IgM antibodies by the Remington test. The classical form of congenital toxoplasmosis was present in five pairs of twins, while toxoplasmosis was subclinical at birth in both twins of three pairs. The pattern of disease varied very much in seven pairs of twins. In one twin of two pairs signs of disease were present, while his cotwin appeared unaffected but with strongly...

Folia Parasitologica 33 7-13 (1986)
The prevalence of anti-Toxoplasma gondii antibodies in serum samples of 55 habitually aborting women, 46 women with normal pregnancies, 92 outpatient adults, and 150 University students from North Jordan was studied using the enzyme linked immunosorbent assay (ELISA). Sera from the habitually aborting group were also tested by the indirect immunofluorescent (IIF) test. No significant difference was found between the overall prevalence rates in University students, outpatient adults and women with normal pregnancies (25.3%, 22.8% and 26.1% respectively). The prevalence in habitually aborting women exceeded two times that in women with normal pregnancies...
Mouse (Mus musculus) as intermediate host of Sarcocystis sp. from the goshawk (Accipiter gentilis).
Folia Parasitologica 33 15-19 (1986)
Sporocysts from the goshawk (Accipiter gentilis) were experimentally transferred to the mouse (Mus musculus). It was found that the goshawk is the host of one of the sarcosporidians inducing muscle sarcocystosis in mice. Thin-walled, sporulated oocysts expelled by the goshawk measured 16.5-19.0 X 12.0-13.0 micron. Those which measured 12.0-13.5 X 8.2-9.0 micron were widely elliptical, with rounded poles. No asexual reproduction of parasites was detected in the viscera of mice. The cysts started to appear in skeletal muscles on day 20 after oral infection with 10,000 or 100,000 sporocysts per mouse. The cysts measuring 15-630 X 18-65 micron contained...

Pathology of experimental Cysticercus bovis infection in the reindeer (Rangifer tarandus Linné, 1758).
K Blazek, V S Kirichek, J Schramlová
Folia Parasitologica 33 39 (1986)
In the present study, the tissue reaction of the brain, skeletal muscles and heart in experimental C. bovis infection of the reindeer is described. There is non-purulent cysticercal leptomeningites with formation of multinucleate symplasms in the cerebral meninges, and lymphocytic encephalitis in the superficial layers of the cerebral cortex. The tissue reaction around the morphologically differentiated cysticercus in the meningeal location is similar to that in muscle cysticercosis of cattle. In muscles and heart, larvae die very soon after infection and they are resorbed in the course of formation of fibroplastic granulation tissue around them. C....

Autoradiographic study of kinetics of spermatogenesis in Ascaris lumbricoides.
D P Mukhopadhyay, C R Maity, A Sengupta, S Ghosal, G Majumdar
Folia Parasitologica 33 61-64 (1986)
The kinetics of meiosis and spermiogenesis in Ascaris lumbricoides in vitro was studied by keeping 12 mature males in nutrient medium. The spermatocytes were made radioactive by supplementing the medium with 3H-thymidine for 2 h, following which they were transferred to fresh medium without 3H-TdR. The nematodes were then killed for preparing histological and squash preparations of the testis. An analysis of the migration of "hot" spermatocytes till the formation of mature spermatozoa, in Kodak AR-10 autoradiograms, suggested that the duration of meiosis and spermiogenesis was a little more than 5.5 and 7.6 days, respectively. The total duration of...

Internal regulatory systems--common consistent patterns in the parasite-host relationships with specific parasites.
Folia Parasitologica 33 71-75 (1986)
While studying the population ecology of cattle warble flies (Diptera, Hypodermatidae) in Czechoslovakia, the Soviet Union and Mongolia a firm internal regulatory system, determining the population density of parasites and operating on the principle of negative feedback, was demonstrated. The negative binomial distribution proved to be a suitable model in other parasite groups as well. The internal regulatory systems are common consistent patterns in the parasite-host relationship with specific parasites. These consistent patterns and the methodical approach to them are of wider importance not only for parasitology in particular, but for the research...

Folia Parasitologica 33 77-86 (1986)
The paper presents the results of faunistic, ecological and viral investigations concerning phlebotomine sandflies in an endemic focus of visceral leishmaniasis in Yugoslavia. These investigations were carried out in the period from 1969 to 1981.
Some diagnostic, biologic and morphologic characteristics of Francisella tularensis strains isolated from the ticks Ixodes ricinus (L.) in the Prague agglomeration.

Four infectious agents were isolated from the ticks Ixodes ricinus (L.) collected in the recreational area and park-forest of Prague. On the basis of cultivation, staining, biochemical, serologic properties, pathogenicity for animals and histological tests they were identified as Francisella tularensis with the following features: they are short, gram-negative rods of approximate dimensions of 0.3 X 0.8 micron, growing in enriched media after 3-4 day incubation at 37 degrees C. They form small circular, at first transparent, later greyish turbid colonies with regular rims. They are little active biochemically. They are susceptible to streptomycin and...
