Snails of Bythinella austriaca agg. from streams in karstic and mountain regions of the Czech Republic (Moravia), Slovak Republic and Poland were examined for larval trematodes. A total of 549 (14.4%) snails were infected and harboured 12 species of cercariae belonging to the families Troglotrematidae, Nanophyetidae, Allocreadiidae, Lecithodendriidae, Microphallidae, and the superfamily Opisthorchioidea. No metacercariae were found in the snails, which indicates that other aquatic invertebrates are used as second intermediate hosts in these areas. It is assumed that Bythinella austriaca agg. plays an important role as the first intermediate host in the life-cycles of trematodes in the Carpathian region of Central Europe.

Records of the European Harpirhynchidae Dubinin, 1957 (Acari, Prostigmata) are summarized and briefly discussed. This family is represented in Europe by 23 species belonging to three subfamilies, Harpirhynchinae (18 species recorded), Harpypalpinae Fain, 1972 (4 species recorded), and Ophioptinae Southcott, 1956 (1 species recorded). A new species Harpirhynchus dusbabeki sp. nov. from the bearded tit Panurus biarmicus (L., 1758) (Passeriformes, Timaliidae) in Slovakia is described. This new species differs morphologically from the two similar congeneric species, H. nidulans Nitzsch, 1818 and H. galeridae Fain, Bochkov et Mironov, 1999, by having setae 3a and two setae on both genua I and II.

Two new species of the feather mite family Gabucinidae (Acari: Astigmata) are described from birds of the family Troglodytidae (Passeriformes) from Central America: Piciformobia cinnycerthiae sp. nov. from Cinnycerthia unirufa (Lafresnaye) in Ecuador, and P. henicorhinae sp. nov. from Henicorhina leucosticte (Cabanis) in Costa Rica. These are the first records of mites of the genus Piciformobia Gaud et Atyeo, 1975 from passerine hosts. A renewed diagnosis of the genus Piciformobia and key to all known species are provided.

Four new species of the feather mite subfamily Pterodectinae (Proctophyllodidae) are described from passerine birds examined in Senegal: Dolichodectes gymnoris sp. nov. from the Russet-browed Bush-sparrow Gymnoris dentata (Sundevall, 1850) (Passeridae), Montesauria plocei sp. nov. from the Village Weaver Ploceus cucullatus (Muller, 1776) (Ploceidae), M. zosteropis sp. nov. from the African Yellow White-eye Zosterops senegalensis Bonaparte, 1850 (Zosteropidae), and Proterothrix terpsiphone sp. nov. from the African Paradise-flycatcher Terpsiphone viridis (Muller, 1776) (Monarchidae). Brief notes on systematics and host associations of the pterodectine genera Dolichodectes Park et Atyeo, 1971, Montesauria Oudemans, 1905, and Proterothrix Gaud, 1968 are also given.

In December 1998, a group of three lynx Lynx lynx (Linnaeus, 1758), possibly a female with kittens was observed during two nights at a killed roe deer Capreolus capreolus in the Bukovske Vrchy hills, north-eastern Slovakia. There was an apparent feeding order among the lynx, with the largest eating first and the smallest last. Also, the "play-fight behaviour" was observed.

Between 1984 and 1987, antibodies to toxoplasmosis in dogs in the southern part of the Czech Republic were monitored. The dogs were German shepherds, reared and used by the border police in the line of their duty. Antibodies were ascertained by the Sabin-Feldman dye test (DT) at a titre of 4 or higher, and by the complement fixation test (CFT) at a titre of 10 or higher. Dogs from 21 kennels were re-tested 7 times (total of 1903 tests). Mean seroprevalence levels ascertained by the DT and CFT were 9.8% (1.7-26.6%) and 3.7% (0.8-6.6%) respectively. The generally low seroprevalence can be explained by high zoohygienic standards at the facilities, use of cooked feed and the fact that the dogs stayed mainly in well-preserved environment. A study was made also to see whether the seroprevalence of antibodies might have been influenced by local climatic conditions and the type of countryside. Differences in the type of countrysides do not seem to have any influence on the seroprevalence.
