The specimens were examined at the Institute of Veterinary Research in Anyang, Korea R. and were identified as Rhipicephilus sanguineus (Latreille 1806). The morphological characteristics observed by means of the scanning electron microscope were presented with some SEM microphotographs. As R. sanguineus was firstly discovered to occur in Korea R, a total of 20 species of ticks belonging to 8 genera such as Argas, Amblyomma, Boophilus, Dermacentor, Haemaphysalis, Hyalomma, Ixodes and Rhipicephalus has now been recorded

In the conditions of the Republic of Belarus there was determined the parasitizing influence of Oesophagostomum and their larvae on a metabolism of experimentally infested animals. In course of the study there were generated experimental and control groups of two-month old piglets. Animals of the experimental group were infested in a dose of 15000 invasion larvae per one kg of body weight. Animals of the control group were not infested. Infestation was realized through a mouth with invasion larvae with wet forage. Invasion larvae received by cultivation of excrement tests from infested pigs at temperature of 24 deg C. As a result of the realized research it was established, that Oesophagostomum invasion rendered a substantial influence on the experimental animals. At bimestrious pigs after the experimental infection with Oesophagostomum larvae there were stated the following changes: the disease on 4-30th day was characterized by frustration of function of a gastroenteric path - diarrhea, fever, anaemia, and in the subsequent - stagnation and juvenilism of animals. Oesophagostomum in a host organism caused the pathological changes of haemotological and biochemical blood value which were expressed in quantity decrease of erythrocytes, concentration of haemoglobin, leucocytosis. Eosinophilia was observed in a leukogram. In blood serum there was stated the lowering of crude protein and its fractions content; gradually, but authentically there was noted the increasing of activity serum glutamic oxalacetic transaminase and glutamic-pyruvic transaminase. Bactericidal and lysozymic activity of blood serum decreased. Activity of alkaline phosphatase increased.

In the conditions of the Republic of Belarus there was studied the influence of herbal infusion, tincture, liquid and dry extracts of elecampane (Inula helenium) on morphological and biochemical indexes of pig blood. In course of the study it was established, that preparative forms of elecampane stimulated the formation of blood corpuscle, and also increased of the hemoglobin level in blood of pigs. Administration of elecampane preparations did not cause any authentic changes in blood leukogram of swine; all indicators were within normal limits. Elecampane preparations did not cause changes on the part of biochemical blood indexes of and did not influence the activity of enzymes. Research results showed that herbal infusion, tincture, liquid and dry extracts of elecampane did not render negative influence on swine.

In the conditions of the Republic of Belarus there was studied a therapeutic effectiveness and influence on milk productivity of 22% Timbendazole after spontaneous infestation of cows with fascioliasis (Fasciola hepatica). As a result of studies the Timbendazole 22% proved to be highly efficient against Fasciola hepatica in cattle – from 92,9% up to 100% (in comparison with Albendatimum-100 granulated material the efficiency of which was 88-90%). As a result of cows treatment by anthelmintics – Timbendazole 22% and Albendatimum-100 against Fasciola hepatica there was stated the substantial increasing of milk productivity of animals (on 23,4 and 11,0%, respectively) in comparison with animals which were not administratec with mentioned above preparations.
