Parasites of domestic and wild pigeons in the south of Ukraine

Pigeons are closely related to human life and are both a source of food and object for hobbies and sports. Parasitic diseases of birds are the main reason for their growth retardation, reduced productivity and viability. The article presents the results of studying the prevalence of trichomonosis, cestodes and nematodes among the population of wild and domestic pigeons in the south of Ukraine. According to the results of the conducted researches it is established that in the south of Ukraine endoparasitoses of domestic and wild pigeons are quite widespread, and all species of this bird are carriers of Trichomonas gallinae. At the same time, the highest rate of Trichomonas infection was recorded in Columba palambus and C. livia domestica, and the overall infestation of males is higher by 4.4% compared to females. It was determined that domestic pigeons C. livia domestica were infested with trichomonosis (27.5%) and nematodes (Ascaridia columbae, 57.1%), C. palambus – trichomonosis (32.1%) and cestodes (Raillietina spp., 82.4%), Streptopelia turtur – cestodes (Raillietina spp., 12.5%) and S. decaocto – cestodes (Raillietina spp., 71.4%) and nematodes (Heterakis gallinarum, A. columbae – 33.3% and 44.4% respectively). The overall rate of infestation of pigeons with cestodes was 28.4% and the incidence in males was higher by 3.9% compared to females. It was found that the most common species among pigeon cestodes is Raillietina spp. In addition, 22.9% of pigeons are carriers of nematodes (H. gallinarum, A. columbae and Capillaria spp.). Continuous monitoring of pigeon parasites is necessary because they, in most cases, come into contact with other species of poultry and are a source of general invasion. In terms of further research, it would be promising to study the prevalence of helminthic infestation among wild migratory birds

The comparative evaluation of complex drugs based on fipronil for ectoparasitosis of dogs and cats

The article presents data on the effectiveness of new domestic antiparasitic drug “Insectostop for dogs and cats” in comparison to the reference drugs “Burdi Fipro for dogs” and “Burdi Fipro for cats” that is used for therapeutic and prophylactic purposes against ectoparasitosis of dogs and cats of different breeds. According to the results of the research, the parasitism of fleas of Ctenocephalus canis, C. felis and Pulex irritans species and parasitiform mites of the Ixodes ricinus and Dermacentor reticulatus species and sarcoptiform mites of the species Otodectes cynotis were detected on experimental animals. Clinically, this was inspected by redness, inflammation of the skin, itching reflex, the emergence of papules on the skin, scales. Based on the results, it was found that 8 hours after usage of the experimental drug “Insectostop for dogs and cats” its effectiveness in syphonapterosis of dogs was 87.9 %, and after usage of the reference drug “Bourdie Fipro for dogs” – 86.9 %, and in experiments on cats, the effectiveness of the experimental drug for siphonapterosis in cats was 92.4 %, and the reference drug “Bourdie Fipro for cats” – 90.3 %. Starting from the first and third days after usage of drugs on the fur of dogs and cats of the experimental and control groups, parasitological studies did not reveal fleas of the species Ctenocephalus canis, C. felis and Pulex irritans. So starting from the first day, the experimental and reference drugs showed 100 % effectiveness during the siphonapterosis in dogs and cats. During the ixodidosis of dogs, it was found that at the 8-th hour after usage of the experimental drug “Insectostop for dogs and cats” its effectiveness was 82.9 %, and after usage of the reference drug “Bourdie Fipro for dogs” – 81.3 %. At the 24-th hour after usage of the experimental drug, its effectiveness was 97.6 %, and after usage of the reference drug – 95.9 %. At the 72nd hour of the experiment, no adult representatives of the species Ixodes ricinus and Dermacentor reticulatus were found on the fur of dogs of these groups. Thus, at 72 hours after usage of the experimental and reference drug, they showed 100 % efficiency on adult Ixodes mites. During the Otodectesis of dogs it was found that on the 7th day, effectiveness of the experimental drug was 75.6 %, on the 14th day – 98.1 % and after usage of the reference drug “Bourdi Fipro for dogs” its effectiveness on the 7th day was 73.5 %, and on the 14th – 98.3 %. At 21-st days after treatment of animals with drugs as a result of clinical examination and parasitological examination of dogs mites of the species Otodectes cynotis were not detected. In experiments on cats, on the 7th day after usage of experimental drug, its effectiveness during Otodectesis of cats was 76.9 %, and after usage of reference drug – 77.1 %. As a result of clinical examination and parasitological study of the experimental and control groups of animals on the 14th day after treatment of the auricles of cats with mites of the species Otodectes cynotis was not detected. Thus, usage of both drugs promotes the release of Otodectesis in dogs from parasites on the 21st day of the experiment, and cats – on the 14th day. Tests have shown that the experimental drug “Insectostop for dogs and cats” (100 ml of the drug contains the active substance: fipronil – 10 g) does not cause skin irritation, dermatitis, seborrhea, allergic and other side effects, that the drug is well tolerated by dogs and cats and doesn’t give any side effects and changes of clinical condition of animals

Hall effect in the vicinity of quantum critical point in Tm1-xYbxB12

The angular, temperature and magnetic field dependences of Hall resistance roH for the rare-earth dodecaboride solid solutions Tm1-xYbxB12 have been studied in a wide vicinity of the quantum critical point (QCP) xC~0.3. The measurements performed in the temperature range 1.9-300 K on high quality single crystals allowed to find out for the first time in these fcc compounds both an appearance of the second harmonic contribution in ro2H at QCP and its enhancement under the Tm to ytterbium substitution and/or with increase of external magnetic field. When the Yb concentration x increases a negative maximum of a significant amplitude was shown to appear on the temperature dependences of Hall coefficient RH(T) for the Tm1-xYbxB12 compounds. Moreover, a complicated activation type behavior of the Hall coefficient is observed at intermediate temperatures for x>0.5 with activation energies Eg~200K and Ea~55-75K in combination with the sign inversion of RH(T) at low temperatures in the coherent regime. The density of states renormalization effects are analyzed within the variation of Yb concentration and the features of the charge transport in various regimes (charge gap formation, intra-gap manybody resonance and coherent regime) are discussed in detail in Tm1-xYbxB12 solid solutions.Comment: 38 pages including 10 figures, 70 reference

Вплив еймеріостатиків на біохімічні та імунологічні показники сироватки крові телят за змішаного перебігу криптоспоридіозу та еймеріозу

Cryptosporidia often parasitize in combination with eimeria and helminths, which leads to a complication of therapeutic treatment measures and to an increase in the level of death among young animals. The scheme of application of medical preparations for animals, which would have high efficiency, remains uncertain. The developed medicinal product "Amprolev-plus" exhibited 100% extensive efficiency for cryptosporidiosis and 95.7 % for eimeria. Therefore, the relevant issue is still as follows: investigation into the influence of eimerostats on biochemical and immunological indices of calves’ blood serum in the mixed invasion course. Within the experiment, 3 days after applying Brovitakoktsid and Amprelev-plus, the total protein content decreased by 0.9 % and 0.7 % and albumin by 5.1 % and 7.1 %, respectively, compared with the control group. After applying Brovitakoktsid, content of β-globulins on the 7th day was 10,20±0,05 g/L, which is almost at the control level of 10.20±0,14 g/L, whereas indicators after applying Amprolev-plus were at the level of 9.80±0.16 g/L, i.e., decreased by 3.9 %. After applying Brovitakoktsid on the 3rd and 7th day, the content of γ-globulins made up of 14.80±0,29 g/L and 14.20±0,10 g/L, and the indicator decreased only on the 14th day to 13.80±0.22 g/L, that is almost the control level of 13.90±0.09 g/L. After applying Amprolev-plus, the indicator gradually decreased from 13.80±0.15 g/L on the 3rd day up to 13.10±0.18 g/L on the 14th day. Albumin/Globulin ratio formed the corresponding A/G coefficient. It was at the level of 0.7‒0.8 in the control group of animals during the entire period of research, as well as in research groups before applying drugs. After applying Brovitakoktsid, the A/G ratio made 1.0 only on the 21st  day of the experiment, whereas after Amprolev-plus application the same ratio was obtained already  on the 14th day. High activity of AST and ALT transaminases was recorded in the invasive calves of both experimental and control groups. The AST activity significantly decreased by 10.2 % only on the 21st day after Brovitakoktsid application, whereas the decrease by 11.2% was observed after Amprolev-plus application on the 14th day, compared to the control. The concentration of circulating immune complexes (CIC) on the 7th day of the experiment in the second group of animals significantly decreased by 7.5 %, while in the first group the CIC concentration decrease by 12.8 % was recorded only on the 14th day of the experiment, which indicates a reduction in the immunosuppression of preparations.У статті наведені дані щодо впливу еймеріостатиків на біохімічні та імунологічні показники сироватки крові телят за змішаного перебігу криптоспоридіозу та еймеріозу. Встановлено, що в сироватці крові телят на 14 добу після застосування бровітакокциду і ампролеву-плюс збільшився вміст альбумінів на 4,8 % та 15,7 % відповідно, тоді як глобуліни зменшилися на 2,4 % та 7,7 %.  Відновлення вмісту загального білку, альбумінів і глобулінів, що стало основою формування А/Г коефіцієнту було відмічено вже на 14 добу після задавання ампролев-плюс, а протягом всього експерименту спостерігалася тенденція до зменшення активності ферментів АлАТ і АсАТ та концентрації циркулюючих імунних комплексів, серомукоїдів, що свідчить про незначну, у порівнянні з бровітакокцидом, імуносупресивну дію препарату
