Materials and methods . The studies were performed in four Gorny Altai physiographic provinces. Ticks were manually collected from horses (1183 specimens). Ticks were counted on natural pastures every ten days with subsequent determination of the species composition (1109 specimens). Collected ticks of the genus Dermacentor (443 specimens) were examined by nested PCR in the presence of genus-specific primers for Babesia spp. and Theileria spp.; the species identification of discovered piroplasmas was determined by 18S rRNA gene sequencing. Results and discussion . Ixodid ticks of three genera (Dermacentor, Ixodes, Haemaphysalis) and 6 species: D. nuttalli , D. silvarum , D. reticulatus , D. marginatus , H. concinna and Ix. Persulcatus , were recorded in the collections from horses and pastures. The most numerous species was D. nuttalli (56.1%), and the most common, Ix. persulcatus , that was recorded in all districts except Kosh-Agachsky in South-Eastern Altai. D. silvarum accounted for 14.9%, and other species were represented to a lesser extent. The highest species diversity, 5 species, was observed in the Northern Altai pastures and only 1 species, D. nuttalli , was recorded in the South-Eastern Altai. The seasonal dynamics of ticks in the pasture was characterized by two peaks in numbers, namely, the spring peak in the 3rd decade of April and the autumn peak in the 2nd decade of October. The spring-summer period (March-June) had 87.1% of recorded ticks, and the autumn period (September-October) had 7.2%. Three species of the examined ticks ( D. silvarum , D. marginatus , D. nuttalli ) were found to have DNA of three piroplasmid species ( Babesia caballi , Theileria equi and Babesia sp). Piroplasmids infection rate in ticks was 2.7-25.0%, and 2.7% on average in Gorny Altai.","PeriodicalId":137857,"journal":{"name":"Rossiĭskiĭ Parazitologicheskiĭ Zhurnal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136182025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and methods. The test of the efficacy of the supramolecular complex of ivermectin was carried out from December 2018 to January 2019 in the North Caucasus Federal District of the Chechen Republic. Two herds of horses of 47 and 54 heads in each of different ages were selected, which were grazed all year round. To determine the infection of horses with nematodes of gastro-intestinal tract, 20 samples of fresh feces from each group were collected from the ground. It was not possible to collect samples from untamed horses to determine the infection by Oxiuris spp. Coproovoscopy was performed using the Fülleborn method. To count eggs in 1 g of faeces, a VIGIS counting chamber was used. The first group was given a 2.0% drug individually in a mixture with food at a dose of 0.15 mg/kg for active substance (AS) (according to the drug 75 mg). The drug was administered to the second group at a dose of 0.2 mg/kg for AS (for the drug 1.0 mg/kg) by the group method in a mixture with food, calculated on a live weight of 500 kg. The efficacy of the drug was determined 2 weeks after deworming according to coproovoscopy data. The efficacy of ivermectin complex was accounted for by the \"critical test\" method. After deworming, the animals were observed during the experiment. Results and discussion. Dehelminthization of horses with a supramolecular complex of ivermectin at a dose of 0.2 mg/kg for AS in a mixture with mixed feed by a group method for mixed infection of various types of gastro-intestinal nematodes under production conditions showed 100% efficiency. Arabinogalactan in the supramolecular complex helps to eliminate the negative effect of AS (ivermectin) on the animal body. The mixture of the preparation with the food was readily consumed by the horses. Deworming horses of herd keeping with a preparation intended for use in a mixture with feed is technically convenient, practically uncomplicated, and at the same time, physical exertion during fixation of animals and industrial injuries are excluded. We did not observe any side effects after deworming horses.","PeriodicalId":137857,"journal":{"name":"Rossiĭskiĭ Parazitologicheskiĭ Zhurnal","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130075216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and methods. The epizootic situation in Georgia on major helminthoses in cattle subject to management systems and the altitudinal zonation of areas location was studied by coprological examination of animals. In 2014–2018, the cattle aged over 2 years held on pasture from March-April until November was studied in homesteads of 59 districts. Similar studies were performed at 19 farms owned by limited liability companies, homesteads and entrepreneurs. The livestock there is presented by Schwyz and Holstein; all processes of care, feeding and milking are mechanized. Results and discussion. Currently, the major helminthoses in pasture cattle in Georgia are paramphistomidosis, fasciolosis, dicrocoeliosis, gastrointestinal strongylatosis and dictyocaulosis which infect 67.5% of the examined cattle. Paramphistomidosis and fasciolosis are found in 59.7 and 21.5% of the examined cattle respectively. With increasing elevation of the altitudinal zonation, the paramphistomidosis and fasciolosis prevalence rates reduce. In case of paramphistomidosis, the infection ranges from 78.4% (low elevation from 0 to 200 m above sea level) to 23.9% (the subalpine area from 1901 to 2300 m above sea level), and in case of fasciolosis, 28.2–8.1% respectively. The rest species of helminths infected cattle to a lesser degree. Dicrocoelium sp. was found in 2.7% of animals, gastrointestinal Strongylata in 6.3%, and Dictyocaulus sp. in 3.9%.

Materials and methods. The work was carried out in a laboratory for invasion diseases of farm animals and poultry of the Caspian Zonal Scientific Research Veterinary Institute, and in the Republic poultry farms. Using Fulleborn’s method, there were 500 excrement samples from chicken aged 1–3 months and laying hens tested, autopsy of 87 birds carried out, and morphological traits of their structure studied, based on which Eimeria tenella and E. necatrix were differentiated. The treatment and protective efficacy of Eimeterm 2.5% was tested in combination with Enrofloxacin in a dose of 3.0 ml per 1 liter of drinking water within 5–6 days. The drugs were given to floor housed broiler chickens with water to drink, namely, Eimeterm was given for two consecutive days in a dose of 7.0 mg/kg of bird weight (28 ml per 100 kg of bird weight), which is equal to 1 ml of the drug per 1 liter of drinking water within 48 hours, or 3 ml of the drug per 1 liter of drinking water which was given to a bird to drink for 8 hours in a day two consecutive days, and Enrofloxacin in a dose of 3.0 ml per 1 liter of drinking water within 5–6 days as compared to basic drug Amprolium. In another poultry house, test broiler chickens were administered 7.5 g of Amprolium 20% in powder form mixed with 1 kg of feed within 7–8 days. The therapeutic efficacy was evaluated by the results of coproscopic examinations and scrapes from different floor sections. A sample autopsy of chickens was carried out to find any morphological change in the digestive tract and Coccidia; intestinal mucosa swabs were tested using the Darling’s method, which was standardized by N. P. Orlov. The results obtained were processed statistically. Results and discussion. The results of broiler chickens’ cecum examinations revealed a high rate of Eimeria infection. Thus, 20–30 oocysts were found in 55 samples in a single microscope field representing 63.2%. The oocysts referred to four species: Е. tenella, E. maxima and Е. mitis in the cecum and small bowel, and E. accervulina in the duodenum. 100% efficacy of Eimeterm 2.5% and Enrofloxacin when combined with water was confirmed. The mortality rate reduced from 137 to 11 animals per day. The survivability of broiler chickens in the test group in the growing period was 94.3%. The autopsy of broiler chickens showed no Eimeriosis-specific changes in the visceras. The tests of 200 cecum swabs and scatoscopy of 20 excrement samples found no Eimeria oocysts.","PeriodicalId":137857,"journal":{"name":"Rossiĭskiĭ Parazitologicheskiĭ Zhurnal","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129320011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
