Revision of tapeworms of family Diphyllobothriidae (Eucestoda: Solenophoridae) from the monitor lizards
VLNOVÁ, Ivana
Diphyllobothriidean tapeworms are well-known parasites of mammals including man, but species parasiting in reptiles are much less known. These tapeworms belong to three genera (Bothridium, Duthiersia, Scyphocephalus) of the family Solenophoridae and are characterized by their unique scolex morphology. They occur in the intestine of varanid lizards and snakes. All three genera are known from Asia, two from Africa (Bothridium and Duthiersia) and one from Australia and South America (Bothridium). Individual genera are well characterised, but species composition of these genera is not well understood. This study surveyed available literary data on the genera Duthiersia and Scyphocephalus and provides new information based on new collected material from Africa and Southeast Asia and material deposited in helminthological collections.

Morphological analysis of the tapeworms eggs of the order Diphyllobothriidea
LEŠTINOVÁ, Kateřina
The order Diphyllobothriidea is a unique group of tapeworms in terms of the wide spectrum of definitive hosts involving all groups of tetrapods including man. They are almost globally distributed in both freshwater and marine ecosystems, but there are also terrestrial species. It is very difficult to identify species of diphyllobothriid cestodes to the species level. Morphology of the eggs might represent a new method in the differential diagnosis of these parasites. Besides the size and shape of the eggs, the structure of egg surface might play a significant role in the determination of different taxa. For the analysis of these characteristics Scanning Electron Microscopy (SEM) was used. Experimental infections in hamsters and man were done.

Manipulation hypothesis: critical review of published works on parasitic invertebrates
TRÁVNÍČKOVÁ, Jana
The manipulation hypothesis has attracted many researchers, and at present it seems to be documented fora wide range of parasites. However, in the last thirty years, numerous parasites have been revealed that, in fact, cannot manipulated with their host morphology, behaviour, and/or habitat preference, unlike conclusions of the previous studies. The major purpose of this study is to test critically the plausibility of the hypothesis about parasitic manipulation, based on metaanalysis of 55 papers concerning four helminth taxa, namely, Acanthocephala, Cestoda, Trematoda, and Nematomorpha.

Tapeworms of family Gryporhynchidae from Africa
HAASOVÁ, Ivana
Morphological-taxonomical study of gryporhynchid cestodes from Africa is presented. New material from Kenya, Senegal and Sudan was studied and we belong to 17 species in 8 orders - Amirthalingamia macracantha (Joyeux et Baer, 1935) Bray, 1974; Anomotaenia riccii (Fuhrmann et Baer, 1943) Baer et Bona, 1960; Cyclustera magna (Baer, 1959) Bona, 1975; Cyclustera sp.; Dendrouterina macrosphincter (Fuhrmann, 1909) Baer et Bona, 1960; Neogryporhynchus sp.; Paradilepis lloydi (Southwell, 1926) Spasski, 1954; Paradilepis maleki (Khalil, 1961); Paradilepis urceina Bona, 1975; Paradilepis urceus (Wedl, 1855) Joyeux et Baer, 1950; Parvitaenia macrocoleo Bona, 1975; Parvitaenia macropeos (Wedl, 1855) Baer et Bona, 1960; Parvitaenia megascolecina Bona, 1975; Parvitaenia purpurea Johri, 1959; Parvitaenia samfyia Mettrick, 1967; Valipora ardeolae (Singh, 1952) Baer et Bona, 1960 and Valipora mutabilis (Linton, 1927). Known larval stages and adults from Africa are presented in review of species.
