Besides Breza's solution the other two concentrating fluids werej used because according to data in the literature {BORAY, 1955; NEMESÉRI and HOLLO, 1972) they are more reliable for the demonstration of tapeworm eggs of higher density. Thej faecal sample was placed on a metal mesh in a plastic dish and mixed with about 10 to 15 ml! of concentrating fluid and left to stand for 10 to 15 min., then, after repeated mixing, the fluid was transferred into a centrifuge tube and centrifuged at 1500 rpm for 3 min. After cenjtrifugation the whole surface layer of the fluid was lifted off with a glass rod of polished endj and the drops placed on glass slides were examined under a cover slip by light microscopy. The exploratory examination was performed at a magnification of x80. The parasitic formations observed were identified by microscopic examination at magnifications of x200 and x40D (KOTLÁN and KOBULE J, 1972; NEMESÉRI and HOLLO, 1972; S LOSS and KEMP, 1978; 1 ROCHETTE and VANPARIJS, 1979). Of the 1674 faecal samples examined by the surface concentration technique, 1243 samples had been obtained from service dogs (mostly German sheepdogs), 246 from dogs treated in the inpatient clinics of the University of Veterinary Science, and 185 from stray dogs taken to pounds or dogs' homes. Of the 150 cat faeces samples 122 had been obtained from cats treated at the University's clinics and 28 from stray cats or those housed in an animals' home. In addition, 200 faecal samples were collected for coprological examination from 11 Budapest parks so that all fresh dog excrements that could be found in a given park after the. dogs were taken for walks in the morning were sampled. The faecal samples were usually processed within 24 hours as of sample collection. In the case of service dogs, however, sometimes a longer time elapsed between sample collection and arrival of the samples in thej laboratory.
