Folia Parasitologica 32[4] 289 (1985)

Results of histopathological examination of a solitary chronical amoebic abscess in the liver of a patient from Cambodia are described. The abscess was at a proliferously reparative phase and Entamoeba histolytica was detected at the border between the necrosis and inner wall of abscess, as well as in the proper non-specific granulation tissue of the inner layers of abscess capsule. A differential diagnosis of the amoebic abscess from similar parasitary or pseudoparasitary liver lesions and differential diagnosis of amoebae in histological sections are given. For orientation examinations of the liver tissue for the presence of amoebae the authors recommend...

Purification of cystozoites of Sarcocystis sp. by the chromatographic gel Spheron.

Folia Parasitologica 32[4] 295-302 (1985)

Cystozoites of Sarcocystis sp. isolated from beef muscles were purified by elution through Spheron chromatographic gel. Using the number of cystozoites recovered and the purity of suspension as criteria, the effect of length of gel column, rate of elution, and ionic strength of the eluent was evaluated. The optimum purity was achieved at the elution rate of 10 ml/min and column length of 100 mm. The recovery of cystozoites (38-56%) was in correlation to the ionic strength of the eluent. Of the current isotonic solutions, Tyrode's solution was found to be the best eluent. Preliminary assays with different coccidia indicate that the method could be used...

Folia Parasitologica 32[4] 323 (1985)

Results of clinical and laboratory examination of animals experimentally infected with Taenia saginata eggs are described. At the early stage of infection, increased temperature, cough, muscle shaking and unstable pace were observed. The locomotive disorders disappeared only on day 50 p.i. Leukocytosis and peripheric eosinophilia were found at the early stage of infection. On days 14-28 p.i. the activity of serum creatine-kinase (CK) significantly increased. The activity of other enzymes (AST, ALT, LD, ALP and ALD) examined was increased only slightly and irregularly. The lipid content in blood serum markedly increased on days 9-16 p.i.

Replication of tick-borne encephalitis (TBE) virus in Ixodes ricinus ticks.

O Kozuch, J Nosek

Folia Parasitologica 32[4] 373-375 (1985)

The influence of external factors on virus carriage of Ixodes ricinus ticks in laboratory and in nature was studied. In laboratory experiment, only one nymph was positive for the presence of virus on 120th day after metamorphosis. The virus titer was 10(2) mouse i.c. LD50/0.03 ml. Transmission experiments were negative. The nymphs were positive on 75th, 111th and 159th day after metamorphosis, always chilling in the field experiment. The titres of virus varied from the lowest detectable amount value to 10(3.6) mouse i.c. LD50/0.03 ml. The transmission of virus was positive in two cases.

Ultrastructure of eggs of Ascaris lumbricoides Linnaeus, 1758. I. Egg-shells.

Folia Parasitologica 32[4] 381 (1985)

Under the light microscope the chitin-protein layer of egg-shells in ascarids appears to be a regular, hyaline and nonstructural layer of 1.5 to 2.00 microns in thickness. The outer uterine layer is usually removed during the preparation. The lipid (ascaroside) layer covers the inner surface of the chitinous layer and seems to be irregularly undulated and regularly thick over the whole surface, with the thickness up to 1 micron. In electron micrographs the fibrous structure of the lipid layer is not evident as a rule. This is probably due to washing the lipids away from this layer during the dehydration of deeper layers of egg-shells that are imperfectly...
