Samples of blood sera collected from 608 sheep in large farms of the districts of Trebisov, Michalovce, Vranov nad Toplou and Humenné were investigated in hemagglutination-inhibition test for the presence of mosquito-borne viruses Sindbis, West Nile, Tahyna and Calovo. Antibodies to arboviruses Tahyna (11.5%) and Calovo (10.9%) were detected most frequently, while a lower sero-positivity was recorded to the Sindbis (2.3%) and West-Nile (1.0%) viruses. Certain differences were found in the infection rates in the respective districts: the highest frequency of antibodies to Tahyna and Calovo viruses was recorded in sheep of the district of Trebisov and the lowest one in animals of the district of Humenné.

755 sheep from 41 farms in the districts of Trebisov, Michalovce, Humenné and Roznava in the East Slovakian region were investigated on the presence of antibodies to Bhanja (neutralization test) and tick-borne encephalitis (haemagglutination-inhibition test) viruses. In respective districts 2.2%, 0.4%, 1.7% and 26.7% of animals (total 5.3%) were found to be positive on Bhanja virus, 4.4%, 1.5%, 1.7% and 5.0% (total 2.6%) on tick-borne encephalitis (TBE) virus. The considerable infection rate in sheep with Bhanja virus in the district of Roznava (mean 26.7%-on one farm as high as 63.9% serologically positive animals) can be explained by the local occurrence of the tick Haemaphysalis punctata, the main vector of this virus in Europe. The serologic screening conducted indicates a low activity of natural foci of TBE in eastern Slovakia today, and confirms the existence of a natural focus of infection with Bhanja virus in the district of Roznava. Recent circulation of Bhanja virus is indicated by antibodies detected in several one-year-old sheep.

Abortions in ewes occurred on a large scale in three localities in eastern Slovakia. Antibodies to the group-type ornithosis antigen were detected in titres of 1 : 128 to 1 : 2048 in the aborting ewes in the mentioned localities. Suspensions were prepared from the four samples of material, obtained either from the placentae and afterbirths of the aborting ewes or from the tissues of the aborted foetuses. Seven-day old yolk sacs of chicken embryos were infected with these suspensions. Four strains of Chlamydia psittaci were isolated and designated EPO-A2-uterus, EPO-B1 aborted foetus-lung, EPO-B2-aborted foetus-lung, EPO-B3-aborted foetus-spleen. Differential diagnosis eliminated some bacteria, toxoplasma, and parainfluenza-3 virus as possible agents responsible for the abortions.

For the subdueing of the clinical form of the synagamosis of pheasants we successfully applied Mebendazole in the dose of 120 mg kg-1 of the feed. Because of the lack of drug we administered the dose of 120 mg kg-1 of the feed in one group in the course of seven days to a number of animals, the others (approx. 4000 animals) received the drug only in the course of three days. On the third to fourth day after the application of the preparation the clinical symptoms disappeared and mortality stopped. To the group intended for dissecting for the evaluation of the effectiveness of Mebendazole, the dose of 120 mg kg-1 of the feed was applied in the course of 13 days. From the fifth day after the beginning of the application we found no gapeworm (Syngamus trachea) in the trachea, and the clinical symptoms disappeared completely from the seventh day onwards. In the control group mortality continued and in the trachea we found mature parasites numbering from 1 to 13 pairs. Thus we consider the dose of 120 mg kg-1 of the feed to be suitable, though it is necessary, by means of further investigation, to determine the most favourable time of administration, both for the prophylactic dehelminthization in dependence on the concrete ecological conditions in the system of rearing, and also for the therapy of the clinical form in dependence on the stage of the pathological process and of the epizootological situation.

The paper presents the results of the clinical tests of fenbendazole (Panacur, produced by Hoechst, F. R. G.), a new antihelminthic preparation. The tests were performed in sheep naturally invaded by gastrointestinal and lung nematodes. Helminthological dissection performed 7 days after the application of 5 mg of fenbendazole per 1 kg of sheep weight proved 100% effectiveness on lungworms (Dictyocaulus filaria) and on the following gastrointestinal helminths: Ostertagia ostertagi, Haemonchus contortus, Bunostomum trigonocephalum, Strongyloides papilosus, Chabertia ovina, Oesophagostomum venulosum, Trichostrongylus spp., and Nematodirus filicollis. The effect on the Trichocephalus ovis species was low and statistically insignificant (37.8%). The tolerance to the chemical was good even in sheep in a very bad condition.
