Incidence and some ecological aspects of avian trypanosomes in Czechoslovakia.

Folia Parasitologica 30[3] 209-222 (1983)

A total of 1 874 birds belonging to 99 species was investigated on the presence of trypanosomes in Czechoslovakia, using the method of blood smears and cultivation from peripheral blood (PEN method) and autopsies with subsequent cultivation from the bone marrow. Apart from a single finding in owls, the trypanosomes were detected only in passerines which represent the majority of birds investigated (1 518 specimens belonging to 66 species). Except for sparrows, in which trypanosomes were present very rarely, they were abundant practically in all bird families represented by a sufficient number of specimens. Autopsies showed that trypanosomes occurred...

Indirect haemagglutination reaction with antigen of Sarcocystis gigantea (Railliet, 1886) Ashford, 1977.

L Cerva, J Gut

Folia Parasitologica 30[3] 223-228 (1983)

The water extract from cryolyzed whole muscle cysts of Sarcocystis gigantea from sheep, in spite of the high lectin content, is a suitable antigen for the detection of specific antibodies by means of indirect haemagglutination reaction (IHA). The agglutinating effect of lectin from parasitic cysts can be eliminated with a 0.5% concentration of lactose dissolved in all solutions used for IHA. In sera of slaughterhouse sheep, positive titres ranging from 1:80 to 1:1 280 were registered. Positive reactions in lower titres were observed also with antibodies against S. dispersa, S. cuniculi and Sarcocystis sp. from pigs. Sensibilized erythrocytes can be...

Morphology and histochemistry of the spicules and gubernaculum of Haemonchus contortus (Nematoda: Trichostrongylidae).

Folia Parasitologica 30[3] 249-255 (1983)

A study has been made of the morphological, histological and histochemical characteristics of spicules and gubernaculum in Haemonchus contortus (Rud., 1803). The correlation coefficients of body length and left and right spicule lengths, left and right spicule lengths, and the distance of barb from the distal end of left and right spicule ends have been found to be statistically significant while the correlation coefficient of body length and gubernaculum length has been found to be non-significant. The sclerotized part of each spicule is composed of three layers differing in density. The shaft of the spicule possesses dorsal and ventral wings which...

Experimental infection with the virulent, Central-European, murine Leptospira pomona strain in the pig.

Folia Parasitologica 30[3] 269-275 (1983)

The virulent, murine Leptospira pomona strain isolated from Apodemus agrarius was used in an experimental infection of six pigs aged 4--5 months. The clinical course of the infection was inapparent, both the blood picture and the uptake of food were normal. All infected pigs produced antibodies against L. pomona at titres from 1:3 200 to 1:50 000. The reisolation of leptospires from the blood of the infected pigs was successful in one case only, and that on day two p.i. Throughout the course of our experiment, no microscopic evidence was obtained of the presence of leptospires in the blood of the infected animals. Of the six guinea pigs injected repeatedly...

The incidence of amoebiasis among secondary school students in Calabar, Nigeria.

Folia Parasitologica 30[3] 277-280 (1983)

A study was conducted among 2 500 secondary school students in Calabar, in order to determine the incidence of amoebiasis caused by Entamoeba histolytica. Microscopic examination of faecal sample smears showed higher percentage infections in the males than in the females; 61 out of 1 250 males were infected (4.8%), while 52 of 1 250 females were infected (4.1%). Among infected persons, asymptomatic carriers (64.6%) and symptomatic cases (35.4%) were recorded. Infection was lower among students using water flush toilet facilities than those using pit and bucket latrines. The infection was attributed to poor sanitation and inadequate health facilities.

The distribution of Angiostrongylus cantonensis (Chen) in the central nervous system of laboratory rats.

Folia Parasitologica 30[3] 281-284 (1983)

The distribution of preadult Angiostrongylus cantonensis helminths in various regions of the central nervous system of rats, infected with varying doses of larvae, was studied. A dose of 10 000 larvae proved to be lethal; the rats showed paralytic symptoms and loss of vision prior to death. A very low dose of 15 larvae also proved to be infective to the central nervous system. Incidence of eye involvement was observed in two rats receiving a dose of 500 larvae. Maximum number of helminths were recovered from the cerebral hemisphere region but their involvement per unit weight of the tissue was found to be highest in the region of medulla oblongata.

Pattern of immune response in recipients after transfer of mesenteric lymph node cells sensitized with low and high doses of Ancylostoma caninum.

V V Vardhani, G N Johri

Folia Parasitologica 30[3] 285-288 (1983)

Cellular immune response was detected in female Swiss albino mice with mesenteric lymph node cells during Ancylostoma caninum infection. Sensitized lymphocytes responded vigorously to A. caninum antigens and it was found that the cells (singly or repeatedly) sensitized with either low or high doses could confer adoptive protective immunity in recipients later challenged with a single dose of 500 A. caninum larvae.
