Folia Parasitologica 35[1] 1 (1988)

On the basis of oocyst morphology, endogenous cycles, prepatent period, and enzyme analysis, Eimeria media was found to be a composite species, representing two independent species differing from all other species of rabbit coccidia. One of them was designated Eimeria media Kessel, 1929 and the other was described as a new species, Eimeria vejdovskyi. E. media has relatively larger oocysts (mean size 32.88 X 19.19 micron), the endogenous development takes place in the epithelium of the ileum or of posterior jejunum, and the developmental stages gradually migrate from the crypts towards the tips of villi. E. media forms three asexual generations, the...

M Giboda, N Vokurková, P Kopácek, O Ditrich, J Gutvirth

Folia Parasitologica 35[1] 11-16 (1988)

Entamoeba polecki Prowazek, 1912 was recorded for the first time in Czechoslovakia in two students from Kampuchea. Uninucleated cysts of diameter 14.2-15.7 micron with nuclei diameter 3.2-4.2 micron were found-repeatedly in stool samples taken from them. The nucleus accounted in average for 24.3% of the cyst diameter. The isolation and two following subinoculations on Dobell-Leidlaw medium were achieved, more abundant growth was recorded on medium with pig serum. Sera of both students were positive in serological tests using the E. histolytica antigen. No serious clinical symptoms were observed, both patients were cured successfully by metronidazole...

Multiciliate sensory endings in the redia of Echinostoma revolutum (Trematoda, Echinostomatidae).

Z Zdárská, V Nasincová, J Valkounová

Folia Parasitologica 35[1] 17 (1988)

In addition to uniciliate sensory endings, three types of multiciliate sensory endings have been demonstrated on the anterior end of Echinostoma revolutum redia using transmission and scanning electron microscopy. This is the first finding of multiciliate sensory endings in the parthenogenetic generation of trematodes. In the first type, 12 cilia are situated in a pit communicating with the tegument surface. In the second and third types, there are two and four short cilia, respectively. They protrude from the nerve bulb above the surface of the tegument. The significance of multiciliate sensory endings in rediae and their similarity to multiciliate...

Transhydrogenase activities in the mitochondria of Taenia crassiceps (Zeder, 1800) cysticerci.

J Zenka, J Prokopic

Folia Parasitologica 35[1] 31-36 (1988)

NADPH/NAD and NADH/NAD transhydrogenase activities have been demonstrated in the mitochondrial fraction of Taenia crassiceps cysticerci. These activities seem to result from the activities of two different enzyme systems. Both transhydrogenase activities exhibited a high heat resistence and they were completely abolished only by the temperatures higher than 100 degrees C. The activity of NADH/NAD transhydrogenase was rather high (116 nmol.min-1.mg-1 protein), but it was found to exhibit a low affinity to NADH (K'M = 1.43.10(-4) M). The physiological significance of NADH/NAD transhydrogenase is discussed.

Levamisole--biological response modifier in Taenia crassiceps--mouse experimental system.

S Lukes

Folia Parasitologica 35[1] 37-40 (1988)

Levamisole, a common anthelminthic preparation, was used for the modification of the immune response of mice to vaccination with soluble antigen from Taenia crassiceps. The combination of antigen with Levamisole significantly increased the immunogenic effect of the antigen. Metacestodes survived in 16.7% after one dose and in 42.9% after two doses of Levamisole. The percentage of resistance was 97.7% and 67.8%.

Data on the morphology of the nematode Spinitectus minor (Stewart, 1914) (Nematoda: Cystidicolidae).

N C De

Folia Parasitologica 35[1] 41 (1988)

Morphology of the nematode Spinitectus minor harboured by Mastacembelus armatus from Burdwan, West Bengal, India was studied by light and scanning electron microscopes. The worms were described, illustrated and discussed taking into consideration of the information available relative to this species. Alate spicules, polar caps on the eggs and prodelphic uteri are clearly seen in the present LM studies and SEM photomicrographs provided detailed information about the microtopography of the worms.

Three interesting nematodes from the fish Parupeneus indicus (Mullidae, Perciformes) of the Indian Ocean, including a new species, Ascarophis parupenei sp. n. (Habronematoidea).

Folia Parasitologica 35[1] 47-57 (1988)

In 1986, samples of the marine commercial fish Parupeneus indicus originating from the Indian Ocean near Somalia were examined for helminths. They proved to harbour three species of adult parasitic nematodes: Ascarophis parupenei sp. n., Philometra lateolabracis (Yamaguti, 1935), and Cucullanus himezi Yamaguti, 1941. A. parupenei sp. n. is characterized mainly by its non-filamented eggs with a fine flock-like coating, length ratio (1: 13-16) of the muscular and glandular parts of oesophagus, length of spicules (0.533-0.600 mm and 0.150-0.171 mm), structure of the head end and shape of the female tail. All these species are briefly described and illustrated...

The effects of host sex and sex hormones on Trichinella spiralis Owen, 1835 and T. pseudospiralis Garkavi, 1972 in the mouse.

V Figallová, J Prokopic

Folia Parasitologica 35[1] 59-66 (1988)

The intensity of Trichinella spiralis and T. pseudospiralis infections and effects of sex hormones, oestrogen (Agofollin) and testosterone (Agovirin), were studied in SPF ICR mice with respect to different sexes of the host. Males were found to be more sensitive to T. spiralis and T. pseudospiralis infections than the females. The number of larvae in the infected mice decreased after the application of the female sex hormone oestrogen to males and male sex hormone testosterone to females.

Acquired resistance of pigeons to Argas polonicus larvae.

F Dusbábek, V Skárková-Spaková

Folia Parasitologica 35[1] 77-84 (1988)

The acquired resistance of pigeons to Argas polonicus manifests itself in an adverse effect on the feeding and further development of larvae. After five subsequent infestations, the rejection of larvae reached 90-95% and the mean weight of fed larvae dropped down from 2.18 mg to 1.72 mg in the Polish tick population. There appeared also a tendency to more rapid feeding in larvae from later infestations. Also the percentage of moulted larvae decreased, probably as a result of insufficient blood meal taken by larvae on repeatedly challenged hosts. The hosts sensitized by larvae of Polish tick population manifested a higher tick resistance than those...
