[Epidemiological findings of Toxoplasma gondii infections of humans in the area of Cottbus].

Using the indirect fluorescence antibody test (IFAT) results concerning the infection of people by Toxoplasma in dependence on age, sex, settlement area and consumption of raw meat in the region of (State Brandenburg) Cottbus are represented as well as on frequency of primoinfections during pregnancy. Infections by Toxoplasma have been found out in 35.6 of 100 cases (n = 3665). With 39.2% women are infected more often than men with 27.1%. Probands of the urbane settlement area show with 37.9% (n = 3402) an higher degree of the infections than probands living in the country with 30.9% (n = 2656). Consumption of raw meat increases the risk of an infection significant. The frequency of primoinfections - found by prospective study with 22559 pregnant women - is placed by 6%, that of connatale infections by 2.6%.

[Toxoplasma gondii infections and oocyst shedding in domestic cats and the significance of this for the epidemiology and epizootiology of toxoplasmosis].

Because of the dissemination of oocysts the cat and other felines have a central position within Toxoplasma gondii epidemiology and epizootiology. From 1984 to 1986, 267 cats between 2 months and 15 years old were serologically examined (SFT) for Toxoplasma antibodies. The rate of infection was 59.9 per cent. The infection rate of stray cats (72.5%) was significantly higher than that of domestic cats (40%). The high infection rate of herbivores results from behaviour of stray cats. In faeces of 264 animals Toxoplasma oocysts could not be proved by flotation technique. But in 39 samples of faeces Toxocara mystax eggs were found, in one sample Toxascaris leonina eggs. Coproscopical examinations did not reflect the real degree of parasitization of cats. The rate of disseminators of oocysts is drainable by Toxoplasma gondii infection found serologically. About 40% of the animals at the age of up to one year were found to excrete Toxoplasma oocysts.

[The effect of anthelmintics on the viability of Taenia saginata oncospheres].

The viability of taeniid eggs has been investigated by means of methylene blue staining. In patients with niclosamide treatment the degree of dead taeniid eggs was 90-100% (19 of 25 cases). In patients without therapy the taeniid eggs were vital in 22 of 25 cases. Therefore recognition and treatment of all taeniid hosts is a way to reduce the taeniosis-cysticercosis extent.

[Cryptosporidium detection in humans].

Cryptosporidium is known as an important cause of gastroenteritis in several animal species, especially in newborn calves and lambs. In our investigations we tested faeces samples of 78 diarrhoeic patients by the method of Ziehl-Neelsen modified after Henriksen. We could find Cryptosporidium oocysts in a boy of one and a half year. Cryptosporidia also should be considered as a cause of diarrhoeas in man.

[Larva migrans visceralis--occurrence of Toxocara canis in dogs in the East German district of Cottbus].

Larvae of the nematode genus Toxocara are the main causative agents of the L.m.v. syndrom. 5,002 dogs from the Cottbus district aged between 2 and 36 months were examined. 994 animals (19.9%) were found to be infected with Toxocara canis. Dogs from a rural area have a higher infection rate (25.6%) than dogs from an urban area (15.2%). The relatively high infection rate of dogs, high egg-production and the tenacity of the development stages are factors dangerous to human health.
