Appendiceal enterobiasis--its incidence and relationships to appendicitis.

J Sterba, M Vlcek

Folia Parasitologica 31[4] 311-318 (1984)

An evaluation was made of a bioptic material (21,916 appendices recovered from 1965 to 1974), in order to disclose relationships of the incidence of Enterobius vermicularis and the origin of appendicitis. A separate evaluation was made of a set of appendectomies (10,619 cases--from 1961 to 1970) for the purpose of detecting changes in pin worm-infested appendices by means of histological methods (683 cases). E. vermicularis was found in 6.03% of appendices. Included in our histological examination was a search for granulomas and eosinophile infiltrations. The former occurred in 1.14% of pin worm-infested appendices, the later in 1.74% and in 0.19%,...

Tissue reaction after subcutaneous injection of Taenia saginata oncospheres.

Folia Parasitologica 31[4] 319 (1984)

After subcutaneous injection of T. saginata oncospheres, a slight swelling is visible at the site of injection first after 13 days. Conspicuous projecting nodes appear after 3-4 weeks. Histological examinations of the site of injection revealed the following changes: On days 3 and 4 p.i.--edema, focal necrosis and haemorrhage, exudation of leukocytes, activation of monocytes and fibroblasts. On day 7 p.i.--in addition to edema and foci of eosinophiles, a striking activation of monocytes and fibroblasts, focal accumulation of macrophages, proliferation of blood capillaries and formation of collagen. On day 10 p.i.--eosinophiles and light macrophages...

Immune response in rabbits experimentally infected with Ascaris suum.

S Lukes

Folia Parasitologica 31[4] 339-343 (1984)

Immune response of rabbits experimentally infected with Ascaris suum was studied by indirect haemagglutination method. The animals were infected with the doses of 5,000, 10,000 and 20,000 infective eggs per animal. Positive reactions were observed from days 5-11 p.i., maximum reactions on days 11-19 p.i. A reinfection with the same doses (1x or 2x after 35 and 65 days) increased the antibody titre. The strongest individual reaction was recorded on day 19 p.i. in the group infected with the highest dose (titre 1 : 4096). The increased antibody titres persisted til the end of the experiment (82th day p.i.) in all groups.

Studies on ticks of veterinary importance in Nigeria XVII. Resistance of rabbits to infestation with Amblyomma variegatum and Boophilus decoloratus (Acari: Ixodidae).

Folia Parasitologica 31[4] 357-362 (1984)

Rabbits exposed to larvae, nymphs and adults of Amblyomma variegatum acquired resistance to the infestation with adults of this tick. The degree of acquired resistance was lowest in the rabbits exposed once previously to larvae and highest in those exposed twice previously to adults. Rabbits also acquired resistance after primary infestation with Boophilus decoloratus; their resistance became very high during the thrice-repeated feeding. New terms are introduced for the quantification of the degree of resistance of animals to tick infestation. Rabbits were protected against infestation with B. decoloratus by intravenous injection of serum from the...

Occurrence of ixodid ticks--the main vectors of tick-borne encephalitis virus in urbanized territory.

E Korenberg, V Cerný, M Daniel

Folia Parasitologica 31[4] 365-370 (1984)

The influence of urbanization on ticks I. ricinus and I. persulcatus--the main vectors of tick-borne encephalitis virus is discussed on the basis of concrete examples. It has been revealed that under favourable conditions the populations of these tick species can exist for a long time not only in towns and new housing estates, but in the old residential districts as well. The necessity of studying the ecology of urban populations of ixodid ticks is pointed out.

Protection against Plasmodium berghei yoelii in chloroquine- and pyrimethamine-treated mice.

V R Pradhan, D M Renapurkar

Folia Parasitologica 31[4] 371-373 (1984)

The antimalarial drugs chloroquine and pyrimethamine were observed to afford protection to mice treated with these agents. This protection was observed in mice when given a subsequent challenge infection after they had been radically cured of P. b. yoelii infection.
