Cryptosporidium infection in beech martens (Martes foina).

Temporary episodes of diarrhea in captive beech martens (Martes foina) were accompanied by shedding of Cryptosporidium oocysts. Oocysts were detected in fecal samples by flotation and in acid-fast-stained smear preparations. The oocysts were 3-5 microns, which is consistent with C.

Three new Sarcocystis species, Sarcocystis giraffae, S. klaseriensis, and S. camelopardalis (Protozoa: Sarcocystidae) from the giraffe (Giraffa camelopardalis) in South Africa.

Three new Sarcocystis species recovered from muscle fibers of the skeletal musculature of a giraffe in South Africa are described based on light and electron microscopy. Sarcocystis giraffae n. sp.

Sarcocystis kirmsei in the brain of a hill mynah (Gracula religiosa).

Cysts of Sarcocystis kirmsei were found in the brain of an exotic bird. The morphological appearance of this protozoon and the changes in the brain tissue are described. This is the second report of S.

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.

Antelopes (Bovidae) kept in European zoological gardens as intermediate hosts of Sarcocystis species.

Four different forms of sarcocysts from the zoo-kept antelopes Addax nasomaculatus. Antilope cervicapra, Taurotragus oryx and Boselaphus tragocamelus (Bovidae) were investigated by light and transmission electron microscopy, in special consideration of the cyst wall. The sarcocysts found in Addax (born in a zoo) were not distinguishable from Sarcocystis medusiformis of Australasian sheep by their morphology and would be the first indication for the occurrence of this species in Europe.

On the diagnostics of Sarcocystis in cattle: sarcocysts of a species unusual for Bos taurus in a dwarf zebu.

Sarcocysts from the musculature of a dwarf zebu born in a German zoo are described by light and transmission electron microscopy. In addition to the three named bovine Sarcocystis species (Sarcocystis cruzi, S. hominis, and S.

The Mongolian gazelle (Procapra gutturosa, Bovidae) as an intermediate host of three Sarcocystis species in Mongolia.

The sarcocysts of three Sarcocystis species (Sporozoa: Coccidia: Sarcocystidae) found in the Mongolian gazelle are described using light and transmission electron microscopy. The host-parasite interface and the ultrastructure of the cyst wall are represented for the first time in the macrocysts of Sarcocystis mongolica Machul'skii, 1947, localised in connective tissue cells. The cyst wall is attributed to type 1 of the classification by Dubey et al.

The black-backed jackal (Carnivora: Canidae) in Namibia as intermediate host of two Sarcocystis species (Protozoa: Sarcocystidae).

Two structurally different sarcocysts are reported from the black-backed jackal (Canis mesomelas) in Namibia by means of light and transmission electron microscopy for the first time. They cannot be attributed to any of the hitherto described Sarcocystis species from Carnivora, of which the ultrastructure of the cyst wall is known.

Cyst wall ultrastructure of two Sarcocystis spp. from European mouflon (Ovis ammon musimon) in Germany compared with domestic sheep.

Muscle samples from six wild and two captive European mouflons (Ovis ammon musimon) in Germany as well as one domestic sheep from a German zoo were infected with sarcocysts (Sarcocystis: Sarcocystidae, Apicomplexa). Sarcocystis tenella and S. arieticanis were identified by light and electron microscopy.

On the morphological diagnostics and host specificity of the Sarcocystis species of some domesticated and wild bovini (cattle, banteng and bison).

Sarcocysts of Sarcocystis cruzi, S. hominis and S. hirsuta were described and compared by means of light (LM) and transmission electron microscopy (TEM) from cattle, bantengs (born in a zoo) and bisons (born in zoo).

Sarcocysts (Sarcocystis sp.: Sporozoa) in the European badger, Meles meles.

Sarcocysts from the tongue muscle of a European badger (Meles meles) are reported for the first time and described by light and transmission electron microscopy. Judging from the ultrastructure of the cyst wall, the parasite is similar to the species Sarcocystis gracilis Rátz, 1909 sensu Erber, Boch & Barth (1978) from roe deer and possibly identical with it. This is noteworthy regarding the intermediate host specificity.

The European badger (Carnivora:Mustelidae) as intermediate host of further three Sarcocystis species (Sporozoa).

Three species of sarcocysts are described by light and electron microscopy from the European badger (Meles meles): Sarcocystis hofmanni n. sp. (a species otherwise occurring in roe deer, Capreolus capreolus), S.

The wisent (Bison bonasus, Bovidae) as an intermediate host of three Sarcocystis species (Apicomplexa: Sarcocystidae) of cattle.

Sarocysts were found in muscle tissue of a wisent (Bison bonasus) which was born and kept in Germany. Light microscopic and TEM examination revealed all the three named species known from cattle: Sarcocystis cruzi ("thin-walled", with longer hair-like villar protrusions of the primary cyst wall); S. hirsuta ("thick-walled", with tongue-like protrusions of the cyst wall arising with very short and narrow stalklets from the surface of the cyst and containing rows of electron-dense granules in the core); and S.

[Sphaerospora truttae (Myxosporidia) in Salmo trutta and Thymallus thymallus: first detection in Thüringia and in the Hartz region and also in the grayling].

S. truttae is described from brown trout and grayling in Middle Germany. This species is obviously not connected with PKX, the causative agent of Proliferative Kidney Disease (PKD) in salmonids.

[The infection process with Sphaerospora renicola (Myxosporidia)].

New data are presented on the development of infection by S. renicola in common carp within the first 15 weeks of their life. The infection of parasite-free common carp succeeded by myxospores as well as by feeding carp kidneys with and without spores in laboratory experiments.

[Coincidental appearance of PKD and Sphaerospora sp. (Myxosporidia) in stock of Salmo gairdneri (Osteichthyes)].

For the first time in Europe simultaneous occurrence of PKX and Sphaerospora sp. is recorded in Salmo gairdneri. Myxosporidian (?) forms hitherto not described have been observed in the kidney interstitium and the epithelium of the renal tubules, sporadically also in the swimbladder wall and the intestinal wall, besides the typical PKX organism in the kidney interstitium.

[The seasonal dynamics of Sphaerospora renicola (Myxosporidia) in carp (Osteichthyes)].

We observed 2 different types of the course of incidence of sporogonic phase and blood phase. Type I shows in both phases a maximum in the first summer, a minimum in winter or autumn and a second maximum between late autumn and second summer. In this case the sporulation was especially distinct with the first maximum.

[Two European Spirometra forms (Cestoidea: Diphyllobothriidae) with different Sparganum growth factors].

European Spirometra forms corresponding to S. erinaceieuropaei in morphology, host specificity and periodical destrobilation were tested for a Sparganum Growth Factor (SGF "mansonoides") acting upon hypophysectomized male rats. A Polish form as well as Thai and Burmese forms did not show a SGF "mansonoides".

[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.).
