[Plerocercoid infestation of the Thailand reptiles in the Berlin Zoo].

Plerocercoids were found under the skin and in the body cavity of Ahaetulla nastua, Boiga multimaculata, Trimeresurus purpureomaculatus, and Varanus dumerilii, imported from Thailand. Starting with these plerocercoids the cestode cycle was experimentally traced in the laboratory (Lueheela = Spirometra sp.). Domestic cat and domestic dog served as definitive hosts, native copepods at first intermediate hosts, native anurans, reptiles, and chicken as second intermediate hosts and paratenic hosts. Fishes and a Rhesus Macque were shown to act as paratenic hosts. The ferret was only suitable as paratenic host but not as definitive host. The adult worm in the definitive host periodically cast off the whole strobila corresponding to a cyclic appearance of eggs in the faeces.

[On the validity of Ichthyocotylurus variegatus (Creplin, 1825) and the species affiliation of Tetracotyle ovata (v. Linstow, 1877) (Trematoda: Strigeidae) (author's transl)].

Ichthyocotylurus variegatus (Creplin, 1825) is a species of its own, differing from Ichthyocotylurus platycephalus (Creplin, 1825). The distinct morphological difference between the metacercariae of the two species must be stressed (Tetracotyle percaefluviatilis v. Linstow, 1877 = I. variegatus Tetracotyle ovata v. Linstow, 1877 = "T. variegata" sensu Hughes, 1928 = "T. pileata" sensu Dubois, 1938, 1968 = T. communis Hughes, 1928 = I. platycephalus), as well as the different location of the maritae in the definitive host (I. variegatus in the posterior third of the small intestine, I. platycephalus in the region of the cloaca). A key for the determination, synonymes and diagnoses of the metacercariae of the 4 Ichthyocotylurus species are presented.

Sarcocystis dubeyella n. sp. and Sarcocystis phacochoeri n. sp. (Protozoa: Sarcocystidae) from the warthog (Phacochoerus aethiopicus) in South Africa.

Sarcocystis dubeyella n. sp. and S. phacochoeri n. sp. from muscle fibers of the skeletal musculature of two warthogs in South Africa are described by light and and electron microscopy. Sarcocystis dubeyella sarcocysts are macroscopic (up to 12 mm long and 1 mm wide), with a parasite-induced encapsulation of the host muscle fiber in which the plasma membrane of the latter remained unaltered. The sarcocyst wall is characterized by evenly arranged, irregularly semicircular or rectangular villar protrusions (5.0 x 2.8-11.0 microns) with indented margins and no specific content. Sarcocystis phacochoeri formed filiform microcysts (up to 4 mm long and 0.13 mm wide). Its cyst wall is provided with tightly packed, molarlike villar protrusions (1.6-3.3 x 1.7-3.3 microns), with smooth margins, hollow on one side, and with longitudinal condensations of the fine granular matrix at various locations in the interior.

[Cercaria splendens Szidat--larva of the trematode Azygia lucii Looss].

The belonging of the only one "gigantic cercaria", Cercaria splendens, to the species Azygia lucii was proved experimentally. The geographic distribution of A. lucii is considerably wider than it has been indicated up to now. The distribution area of A. robusta is also confined not only to the Asiatic part of the USSR. The following characters are suggested for distinguishing the Azygia species: the shape and size of the pharynx, the spread of vitellaria beyond the posterior border of the testes and ratio between the sizes of suckers.
