The article is devoted to the study of the biotic potential and the role of the cestode Echinococcus granulosus in the infection of shepherd dogs and sheep in the republic. It has been established that the average intensity of invasion (II) of the causative agent of echinococcosis in shepherd dogs in the surveyed areas (Kizlyarsky, Laksky, Nogaysky, Sergokalinsky, Suleiman – Stalsky, Khasavyurt, Tsumadinsky, Shamilsky, etc.) is 1768 ± 245; 2924 ± 369; 3456 ± 382; 4683 ± 597; 2249 ± 321; 1870 ± 263; 2633 ± 352; 2149 ± 286 specimens / specimen. Infection of adult sheep with echinococcosis occurs in all surveyed areas, with fluctuations in the intensity of invasion (II) from 14.8 ± 1.3 to 21.3 ± 1.9 specimens / specimen, on average 17.56 ± 1.53 specimens. /individual. In sheep of all age groups, with a complete helminthological autopsy, in 1 ml of echinococcal fluid, fertile larvocysts were found in an amount of 20.36 ± 1.15 specimens / individual, except for young sheep, up to 1 year old. In sheep under the age of 2 years, fertile larvocysts of Echinococcus granulosus are found in the amount of 9.2 ± 0.41 specimens / specimen 0.83 ± 0.076 thousand specimens. The average number of fertile larvocysts found in 1 ml of fluid in sheep at the age of up to 3 years is 15.8 ± 0.93 specimens / individual and 1.15 ± 0.098 thousand specimens; up to 4 years old – 20.5 ± 1.17 specimens / individual and 1.92 ± 0.17 thousand specimens; up to 5 years – 27.3 ± 1.69 specimens / individual and 2.58 ± 0.26 thousand specimens; up to 6 years old – 36.7 ± 1.88 specimens / individual and 3.06 ± 0.49 thousand specimens. These data indicate an increase in the role and activity of the ovine variant of the causative agent of echinococcosis Echinococcus granulosus.

The main purpose of the research work is to identify the prevalence of helminthiasis in private sheep-breeding farms of the Sheki, Zagatala and Oguz districts of the Republic of Azerbaijan. One of the urgent problems is the study of mixed invasions that cause damage to animal husbandry. Based on this, as a result of the investigations, the extensiveness and intensity of helminthiasis in sheep of different age groups were studied as a result of the examinations. Extensiveness of invasion: in Sheki district for moniesiasis — 26.6%, for fascioliasis — 20.8%, for dicroceliosis — 23.3%, in Zagatala district for moniesiasis — 21.6%, for fascioliasis — 15.8%, for dicroceliosis — 17.5%, in Oguz distirct for monieziasis — 30.8%, for fascioliasis — 25.8%, for dicroceliosis — 28.3% were identified during the scatological examinations conducted. Presence the intensity of invasion on average: in the Sheki district with Moniezia expansa — 2–6, Fasciola hepatica — 4–14, Dicrocoelium lanceatum — 7–21, in the Zagatala district with Moniezia expansa — 1–4, Fasciola hepatica — 3–11, Dicrocoelium lanceatum — 5–17, in the Oguz district with Moniezia expansa — 2–7, Fasciola hepatica — 5–18, Dicrocoelium lanceatum — 9–24 specimens were identified when examining during the autopsy.

The article presents the results of epidemiological studies of the role of rotavirus in the development of acute diarrheal diseases in children in the Republic of Uzbekistan. Practice of new epidemiological criteria allowed to differentiate the different intensity of the epidemic process and the manifestation of epidemiological patterns of rotavirus infection depending on the region of the republic. The probability of participation of rotaviruses in the formation of the epidemic process in acute diarrheal diseases is proved. The study was conducted in two regions of the republic differing from each other by economic and social conditions. The material for this study was the data obtained as a result of a serological study of feces samples taken from patients with acute diarrheal diseases before the age of 5 years. When examining 1597 children with acute diarrhea in 532 (33.3%) cases, we were able to establish the presence of rotavirus antigens in the feces. Summarizing the above, we can assume that in the Republic of Uzbekistan, rotaviruses occupy one of the leading places in the etiological structure of acute diarrheal diseases, especially in younger age groups.

The paper discusses epizootic situation of cattle brucellosis in the Republic of Kazakhstan and the subjects of the Kostanai region. The system of comprehensive anti-brucellosis measures based on the major principles with integrated organizational, economic, general veterinary and sanitary and special measures using specific prevention means according to certain schemes or without them, depending on the current epizootic situation, which transfers brucellosis into the category of controlled or potentially curable ones, is analyzed. Convincing evidence of the role of these factors in relation to the success of prevention and rehabilitation of infected herds is provided. The long-term research results indicate that in the regions largely affected by brucellosis complete recovery of cattle without specific prevention measures is practically impossible. In this regard, to eliminate the risk of infection we proposed schemes of anti-brucellosis immunization in safe regions and the subjects affected to different degrees, as well as that for imported pedigree cattle and its offspring. The schemes stipulate vaccines (dosage, frequency, place of immunization, intervals, timing of revaccination, etc.), timing and methods of examination different gender and age groups of cattle.

This article provides data on the research work carried out to identify echinococcosis among small cattle of different age groups in the Republic of Tajikistan. Echinococcosis of farm animals with a high intensity of invasion is recorded in all areas studied by us, in the valley, foothill and mountain zones. Thus, out of the examined 23 364 organs from slaughtered sheep, 17 850 animals, or 76.40%, were affected by echinococcus. In the farms of the valley zone with distant-pasture sheep breeding, the average prevalence was 72.4%, in the foothill zone with distant-pasture sheep breeding – 90.4%, and in the mountain zone – 59.3%. Slaughtered livestock has a high prevalence not only in the context of zones and districts, but also within farms of the same district, depending on the conditions of keeping the sheep and the number of dogs in the flocks. Thus, in farms with distant-pasture sheep breeding in the valley zone of the same district, the infection rate reached 75.0%, while in the mountain zone only 54.2%. The study for echinococcosis of cattle of different sex and age groups found the same pattern as in sheep, i.e. the prevalence increased with age: from 12% in animals under 2 years old to 39.4% in animals of 3–4 years old and 41.6% in animals older than 5 years.

We determined responses of third-generation intrapulmonary arteries and veins of fetal, newborn, and adult sheep to endothelin-1 (ET) and the role of endothelium and cyclooxygenase metabolites in ET effects in adult sheep lung vessels. Presence of endothelium in vessel rings was confirmed by response to endothelium-dependent vasodilators, acetylcholine or bradykinin. Vessel tension induced by ET was expressed as a percentage of tension induced by 100 mM KCl. We found that arteries and veins contracted to 10(-9) to 10(-6) M ET in a dose-dependent manner. Veins exhibited greater sensitivity to ET than arteries in all age groups. Arteries and veins of adult sheep lungs were more sensitive to ET than those of fetal and newborn lambs. In adult sheep lung vessels, pretreatment with indomethacin (5 x 10(-6) M) and SQ 29548, a thromboxane A2-prostaglandin H2 receptor antagonist (10(-5) M), significantly attenuated venous contraction to ET; arterial contraction was unaffected. Denuding vessels of endothelium did not affect responses to ET. We conclude that, in ovine lungs, veins are more sensitive to ET than arteries and that developmental differences in pulmonary vascular responses to ET exist.

The epizootic situation of intestinal nematodes was studied in some farms of the Republic of Tatarstan. The object of the study was horses of different age groups, breeds, sexes, spontaneously – infested with nematodoses. When studying the epi-zootological situation, indicators of extensed invasion (EI) and intensed invasion (II) were used, which were determined by studying the faeces of animals by the hel-minthic scattering modified Kotelnikov-Khrenov method. In 2016, 32 animals were studied for intestinal nematodoses of horses in the amount of 32 Nurlat stud farm limited liability company of Nurlat district of the Republic of Tatarstan. Extensed invasion of stronghylazoses amounted to 40.6%, with the intensity of invasiveness from 7.6 to 1816.4 spec. eggs in 1 g of feces, the intensity of invasion by mixed inva-sion (strongilitoza of the digestive tract + parascariosis) was 21.9%, with a degree of invasion from 15.2 to 3777.2 eggs of the nematode of the Strongylata suborder and from 22.8 to 1603.6 eggs Parascaris Eguorum in 1 gram of feces. When examining 22 horses in 2019, the Khamitov RM farm was found that the horses examined were free from helminths. During the examination of 10 horses of PL “Alekseevskoye”, it was revealed that 10 animals were infested with strongyloses of the digestive tract (EI-100%). The intensity of the invasiveness of horses by the pathogens of the strut of the digestive tract ranged from 15.2-296.4 eggs per gram of feces. In FF "Avza-lov G.G." of Aktanyshsky district of the Republic of Tatarstan, the extensiveness of horses with strongholds of the digestive tract was 40%, with intensed invasion from 15.2 to 273.6 eggs per 1 gram of faeces, extensed invasion with helminths from the sub-order Strongylata + Parascaris, 7%, with a degree of invasion – 395.2 eggs of ematodes of the suborder Strongylata and from 258.4 eggs of P. eguorum in 1 gram of feces. And the animals of the Khamitova RM farm were free from nematodes.

Compared to the attention that children's literature scholars have paid to the construction of childhood in children's literature and the role of adults as authors, mediators and readers of children's books, few researchers have made a systematic study of adults as characters in children's books. This article analyses the construction of adulthood in a selection of texts by the Dutch author and Astrid Lindgren Memorial Award winner Guus Kuijer and connects them with Elisabeth Young-Bruehl's recent concept of ‘childism’ – a form of prejudice targeted against children. Whereas Kuijer published a severe critique of adulthood in Het geminachte kind [The despised child] (1980), in his literary works he explores a variety of positions that adults can take towards children, with varying degrees of childist features. Such a systematic and comparative analysis of the way grown-ups are characterised in children's texts helps to shed light on a didactic potential that materialises in different adult subject positions. After all, not only literary and artistic aspects of children's literature may be aimed at the adult reader (as well as the child), but also the didactic aspect of children's books can cross over between different age groups.

Evidently, a few months after the Jakarta Charter was signed, Christian circles from Eastern Indonesia submitted an ultimatum, if the seven words in the Jakarta Charter were still included in the Preamble to the 1945 Constitution, then the consequence was that they would not want to join the Republic of Indonesia. The main reason put forward by Pastor Octavian was that Indonesia was seen from its georaphical interests and structure, Western Indonesia was known as the base of Islamic camouflage, while eastern Indonesia was the basis for Christian communities. Oktavianus added that Christians as an integral part of this nation need to realize that they also have the right to life, religious rights, political rights, economic rights, the same rights to the nation and state as other citizens, who in fact are mostly Muslims. This paper aims to determine and understand the extent to which the basic assumptions of the Indonesian people view the role of Islam as presented in an exclusive format.
