During the period 2012-2013 investigations of blood samples from domestic dogs ( Canis familiaris ), goldon jackals ( Canis aureus ) and red foxes ( Vulpes vulpes ) origi- nated from different regions of Bulgaria were performed aiming to document diversity and morphometric characte- ristics of established filarial larvae. Following features of microfilariae were analyzed: peculiarities in the shape, body length and maximum body width. According to the morphological characteristics three types of larvae were observed. Larvae of the first type were with pointed ante- rior end and long, thin, straight and sharp tail; those of the second type were with obtuse anterior end and sharp tail, often ending as an umbrella handing; larvae of the third type were with obtuse anterior end and thin, sharp tail, in the most cases curved as a hook. Established filarial larvae were related to following species - Dirofilaria immi- tis, D. repens and Acanthocheilonema reconditum. The lengths of microfilariae of the dogs which we related to D. immitis ranged between 237 and 350 µm and mean value was 297 µm. Microfilariae’ length related to D. repens ranged from 305 to 420 µm (mean 365 µm) and those of А. reconditum were from 223 to 287 (mean 261) µm. In gol- den jackals length of microfilariae was from 253 to 344 (mean 309) µm for D. immitis and 224-285 (mean 250) µm for А. reconditum. In red foxes microfilariae’ length ranged as follows: from 246 to 320 (mean 281) µm for D. immitis, from 291 to 355 (mean 321) µm for D. repens and from 223 to 263 (mean 245) µm for А. reconditum

Objective of research: to study the caryopathic effect of bio-preparation Bacillus subtilis 12В on the status of spermatogenic epithelium of white mice after a single intra-abdominal administration of the Fasciola hepatica extract. Materials and methods: The investigations were conducted on white male mice after oral use of preparation Sporovite based on B. subtilis 12B; then the intra-abdominal injection of F. hepatica extracts at a dose of 100 mkg/head was applied. The protein extract from F. hepatica was administered to mice of the second group, and animals of the third group received only the probiotic Sporovite. Animals of the fourth group did not get the preparation and served as controls. 48 hours later the animals were killed; touch smears obtained from testis were stained by the Romanovsky method and examined under a microscope what enables to determine the mitotic index and the number of pathological meiosis forms. The experiments were conducted on lambs whose seminal vesicles were placed into a solution of 10% Formalin and examined histologically. 2-3µ-thick slices were stained with Haematoxylin and Eosin by Van Gieson method and examined under a microscope at 50, 400 and 1000 x magnifications. Results and discussion: During the pathomorphological and caryomitotic studies of testis of white mice and lambs after administration of Sporovite on the background of intra-abdominal injection of F. hepatica extract the reduction of negative effects on the status of spermatogenic epithelium of testis in animals wasn’t observed. A decrease in mitotic index by 2-3 times and a high amount of pathological forms were registered. The number of metaphases with preterm chromosome disjunction under the joint effect of F. hepatica and B. subtilis extracts has decreased by half.

Objective of research. The purpose of the study is to test the effectiveness of anthelmintic helminthiasis of the digestive tract of cattle and to offer practices for the most effective of them. Materials and methods. Tests of anthelmintic held in LLP "Diet" West Kazakhstan region 40 animals, spontaneously infested strangulate of the digestive tract. Cattle were divided into 4 groups of 10 animals each. Animals of the first group was administered ivermec 1% solution intramuscularly in a dose of 0.2 mg/kg at ET rate of 0.02 ml/kg Animals of the second group asked alot oral-suspension in a dose of 7.5 mg/kg on ET rate of 0.75 ml/kg of Levamisole was administered subcutaneously to animals of the 3rd group at a dose of 7.5 mg/kg at a rate of 0.1 ml/kg. Animals of the fourth group was used and served as control. The effectiveness of the drugs considered through 18 days after deworming according to the results Koprivshtitsa studies by flotation using counting chambers WIKIS and efficiency calculation type "control test". Results and discussion. In the first group the efficacy was 100%. In the second group, EE - 90%, IE-98,9%. In the third group EE-80%, IE-98,5%. In the fourth group the invasion of animals has not significantly changed and amounted to 108,1 beginning of the experiment and after 18 days of 110.4 of strongest. Thus, ivermec is most effective during the helminthiasis of the digestive tract of cattle.

Abstract Objective of research. The aim of the study was to examine the effectiveness of alvet-suspension when strongylatosis the digestive tract of sheep. Materials and methods. Test alvet-suspension was carried out in LLP "Diet" West Kazakhstan region 40 sheep, spontaneously infested strangulate of the digestive tract. Sheep were divided into 4 groups of 10 animals each. The sheep of the first group asked alot oral-suspension in a dose of 5 mg/kg on ET rate of 0.05 ml/kg Animals of the second group was administered ivermec 1% solution intramuscularly in a dose of 0.2 mg/kg at ET rate of 0.02 ml/kg of Levamisole was administered subcutaneously to sheep 3-the third group at a dose of 7.5 mg/kg at a rate of 0.1 ml/kg Animals of the fourth group was used and served as control. The effectiveness of the drugs considered through 18 days after deworming according to the results Koprivshtitsa studies by flotation using counting chambers WIKIS and efficiency calculation type "control test". Results and discussion. Extendedrequest (EE) and intensifications (IE) alvita-suspension was respectively 90 and 96 %. 9 out of 10 treated Alvestam-suspension of the first group of animals freed from worms. In the second group, which used ivermec, worming released 9 of the 10 treated animals. EE and IE was 90 and 95 %. In the third group, which used the levamisole, the worms have released 7 of the 10 treated animals. EE and EI were 70 and 78 %. The low efficiency of levamisole compared with other drugs can be explained by the development of resistance to the action of strongest of the digestive tract, as this anthelmintic was used previously. During the experience the invasion of animals of the control groups were not significantly changed. Alvet-suspension 10 % in a dose of 5 mg/kg in a production environment is a highly effective drug when strongylatosis the digestive tract of sheep.

Abstract Objective of research: to study the inactivation of eggs of Opisthorchis felineus and Diphyllobothrium latum in the water by the narrowband ultraviolet excimer lamp radiation 222 and 282 nm depending on the surface radiation dose. Materials and methods: Helminth eggs were detected by the Kato technique. The revealed eggs were flushed into a plastic container with the distilled water and exposed to UV. The inactivation of eggs was confirmed by the method of optical microscopy. Results and discussion: It was found that the recovery of helminth eggs from water was 40-70% more efficient by using UV radiation at 222 nm than at 282 nm. In addition, the surface radiation dose at 222 nm (up to 5 mJ/cm2) was one order less than at 282 nm (up to 100 mJ/cm2). Up to 30 % of the initial amount of Opisthorchis felineus eggs were inactivated at 282 nm surface radiation dose (up to 100 mJ/cm2). Up to 85 % of the initial quantity of Opisthorchis felineus eggs were inactivated at 222 nm radiation on the water surface (up to 5 mJ/cm2). Up to 56 % of Diphyllobothrium latum eggs were inactivated at the comparable 222 nm surface radiation dose. Due to the higher photon energy, the more intensive shortwave radiation at 222 nm breaks shells of Opisthorchis felineus eggs more effectively. We have a reason to suppose that some features of Diphyllobothrium latum egg shells make its inactivation at 222 nm less efficient in comparison with the inactivation of Opisthorchis felineus eggs at the same wavelength of radiation.
