It has been established that there is a violation of the immunocompetence of the macroorganism at diseases of the gastrointestinal tract which are accompanied by diarrhea. Since the immune system is one of the most important homeostatic systems in the body, these disorders play an important role in the pathogenesis of the disease. Thus, the purpose of the work was to study the indicators of natural resistance and immunological reactivity in calves with gastroenteritis. The research was carried out at the state enterprise «Milk Rinks»Pravda LTD in Brody district of Lviv region on 1.5–2-month-old-calves. 15 calves were selected for the study: 5 healthy ones and 10 patients with gastroenteritis. Blood for research was taken from the jugular vein before the early feeding.In the study of indicators of natural resistance, it was found that in calves with gastroenteritis, the content of circulating immune complexes in serum is authentically (P < 0.001) greater than 45.1%, bactericidal and lysozyme activity of serum is authentically (P < 0.01 ) lower at 15.1 and 26.3% and phagocytic activity of neutrophils – by 8.6% compared with healthy animals. In the study of lymphocytes and their subpopulations, it was found that the relative amount of T-total and T-active lymphocytes is authentically (P < 0.01) less by 8.6 and 11.7%, respectively, compared with healthy animals, the relative number of T-helper cells – less than 16.4% (P < 0.01). There is no probable difference in the relative number of T-suppressors between patients and healthy animals, but the immunoregulatory index in calves, patients with gastroenteritis, is 19.4% smaller, compared with healthy ones. The relative number of B-lymphocytes was authentically (P < 0.01) less in sick animals by 14.5% compared with clinically healthy ones, and the content of immunoglobulins in serum was lower by 16.3% (P < 0.01). Conclusion: in calves, patients with gastroenteritis, there are a number of violations of the immune system, characterized by a decrease in the parameters of cellular and humoral immunity, which require correction in the process of treatment.

The immune system is central to ensuring the consistency of the body's homeostasis. The state of the body's natural resistance is determined by a set of non-specific protective mechanisms. Lymphocytes and phagocytes are actively involved in maintaining immunity. Lymphocytes recognize the antigens of pathogenic microorganisms, and phagocytes absorb and destroy the pathogens themselves. During the weaning of piglets from sows there is a decrease in the protective forces of their body. During this period, the natural resistance of the piglets is reduced due to the stressful situation caused by changing conditions of confinement, the transition to full feed and lack of sows. The immune system of weaning pigs is relatively weak, so when exposed to environmental and technological stressors, they become susceptible to various diseases. The use of probiotic drugs stimulates the activity of the immune system, prevents stress and immunodeficiency. One of these probiotics is the probiotic of domestic production Protecto-active. It w observed the the influence of the probiotic Protecto-active on the indices of nonspecific resistance of the young pigs organism to the growth. An increase in bactericidal activity of blood serum by 12.10% (P <0.05) and lysozyme activity of blood in the piglets of the experimental group was increased by 3.71% compared to control, which indicates the activation of the body's defenses and the increase in adaptive capacity. An important step in the study of the influence of the probiotic Protekto-active on the state of the immune system is to determine the phagocytic activity of neutrophils, phagocytic index and phagocytic number. In the experimental group of piglets that were fed the probiotic Protecto-active, we found an increase in leukocyte phagocytic activity by 9.0% (P <0.001), a phagocytic index by 51.7% (P<0.001) and a phagocytic number by 24.8% ( P <0.01) compared with the control group. Thus, using a probiotic Protecto-active, all indicators of phagocytosis increase: the number of phagocytes increases, their ability to capture microorganisms and increases their digestive capacity, it increases the bacterial and lysozyme activity of blood serum, which is positively reflected in the immunobiosity. Key words: probiotic, phagocytosis, phagocytic index, phagocytic number, phagocytic activity of leukocytes, cellular immunity, piglets

The aim of the study was the evaluation of the function of the immune system in chicken pox patients based on clinical and laboratory data. There were examined 75 patients. The study on phenotypic composition of cells in innate immunity was executed with the method of flow cytometry. A detailed study of the immune system in chickenpox patients revealed the alteration in the composition of the subpopulation of T-lymphocytes, with declining populations of T-helper cells, namely, the lowering of relative and absolute number of CD3+ CD4+ and an increase in the relative number of CD3+CD8+ lymphocytes, which is indicative of immunosuppression. No changes according to the number of NK cells, which must actively respond to viral infection (the final stage of activation of cell growth with an increase in their number in peripheral blood). The absence of their increase is indicative of the irresponsive immunity in chickenpox patients

The article presents data on the dynamics of cellular immune system factors of the arctic foxes (Vulpes lagopus) while being affected by mixtinvasion of protozoa (Isospora vulpina) and helminth (Toxascaris leonina). The changes in the blood cell composition, in particular those responsible for the body’s immunity and immune status, reflect the pathological effect of the endoparasites on the animal’s body. The development of the invasive process during mixtinvasions causes and is accompanied by a decrease in the level of nonspecific resistance of the host organism. In addition, a significant process of inhibition of the lysozyme complementary activity in the blood serum and the development of secondary immunodeficiencies is observed. The aim of our work was to study the development of the pathological process in arctic foxes, caused by previously detected mixtinvasion by eimeriidoses and helminthiases, as well as to identify dynamical patterns of the immune system cellular factors. Intravital diagnostics of parasitoses was carried out by means of coproscopic studies with the help of conventional flotation methods. 127 arctic foxes participated in the experiment. Among them individuals with double invasion, an invasion with both protozoa (placeI. vulpina) and helminth (T. leonina), were selected for the experiment. Healthy animals served as the control group. Arctic foxes which took part in the experiment were divided into three groups of 10 animals each. Groups were formed by the method of balanced analogous groups. Evaluation of the T-system of immunity was carried out by the method of spontaneous rosetting according to Jondal (1972). Isolation of lymphocytes by the method of A. Boyum (1968), B-lymphocytes were determined by the method of E. Mendes (1973), theophylline-resistant and theophylline-sensitive T-lymphocytes were determined using the method of S. Limatibul et.al. (1978). The immunoregulation index was calculated by the ratio of T-helpers to T-suppressors. During the experiment, it was found that in infected animals the total number of lymphocytes was significantly 10.2 % higher than in animals in the control group, however, there was a tendency to a sharp decrease in the total number of lymphocytes in patients with I. vulpina + T. leonina. The T-helper dynamics in infected foxes was 18.9 ± 0.9 (P≤0.05), which is 21.9 % less than in the control – 24.2 ± 0.6 (P≤0, 05). The dynamics of T-suppressors turned out to be directly opposite to the dynamics of the T-helpers. The dynamics of B-lymphocytes in the 2nd group turned out to be 1.76 times higher than in animals from the control. In the 3rd group same indicator was comparable with the control values of 2.9 ± 0.3, against 2.5 ± 0.4 in the control group. The study showed that mixtinvasion with placeI. vulpina + T. leonina leads to immunosuppression in the arctic foxes. Interestingly the specific therapy did not straighten the immune state of the animals, but on the contrary it became more pronounced, which suggests that antiparasitic drugs have an immunosuppressive nature on the body of arctic foxes as evidenced by violations of the parameters of the body’s natural resistance, the content of T-E-ROCK lymphocytes.

Deep Relationship

Sometimes, an increased reaction is caused by an immune system of the body to a non-toxic agent (e. g. eggs, dust, pollens or some drugs). This is called allergy or hypersensitivity. The regulatory T cells decrease these allergic reactions. Nowadays, it is noticed that immune system has a deep relationship with micro-organism present in the intestine, that can be explained by the example, that some bacteria of intestine increase production of Treg cells by producing butyric acid like fatty acids. This can also understand that sufficiently different types of T cell receptors of Treg cells are needed to stop the inflammatory response produced by intestinal bacteria. In this study, the dynamic relation of T helper cells, intestinal bacteria and Treg cells are illustrated by a conformable mathematical model. Memory effects are figured out and displayed through graphs. Different plots also show the effects of increasing/decreasing amount of Treg induction efficiency on the whole system.

Antioxidant Protection System

The study of the human immune system state in infection with M. tuberculosis is relevant because the course and outcome of this disease are largely determined by the immune status of the patient. However, 98 % of patients with pulmonary tuberculosis have an immune imbalance. It is known that in the protection against tuberculosis an important role belongs to the body's natural resistance, which is provided by a variety of cellular and humoral factors, physicochemical characteristics of tissues, lymphoid cells, leukocyte and macrophage responses and genetic resistance. When mycobacteria enter the body, polymorphonuclear leukocytes, monocytes and macrophages are the main phagocytic cells. Optimally high level of resistance to the pathogen develops only in the coordinated interaction of T−lymphocytes with macrophages. Studies of cellular immunity and genetic markers have shown that the course of tuberculosis infection is associated with suppression of their functional activity. Immune response deregulation is closely related to oxidative stress, which results from an imbalance between free reactive oxygen species and antioxidant mechanisms, with a higher risk of developing it rather in lungs than other organs. Many studies have presented the results of studying the state of the immune system and the "oxidative stress − antioxidant protection" system in tuberculosis. This is an important component, because the clinical course and outcome of treatment is largely determined by the status of these systems. A number of experts point out that the study of immunological and oxidative parameters in tuberculosis is of a great importance for deciding on the tactics of treatment and the choice of direction of influence on the course of the disease. Key words: M. Tuberculosis, immunity in tuberculosis, oxidative stress, antioxidant protection.

Abstract. Modern conditions of animal husbandry and poultry farming dictate a continuous search for effective means that increase the natural resistance of the organism of farm animals and poultry. The purpose of the study. In this regard, an experimental study was conducted on laboratory animals using a mineral adaptogen of domestic production in order to determine its effectiveness in conditions of artificially induced immunosuppression. The objectives of the study were to determine the immunobiochemical status, subcellular and intra-organ changes in the organs of the immune system at all levels. Research methods. Experimental studies were carried out using generally accepted zootechnical, pathomorphological, histological, immunobiochemical and statistical research methods. Results. Immunobiochemical changes in the body of experimental animals are described. Microscopic changes at the level of tissues and cells in the organs of the immune system at all levels are described. Changes in the organs of the immune system during immunosuppression and against the background of feeding mineral adaptogen are described. Morphological examination of the immune system organs in experimental animals revealed prolonged immunosuppressive changes for 14 days. At the same time, after induced immunosuppression, significant structural changes remain in the central and peripheral organs of the immune system in the form of lymphoid tissue atrophy (in the thymus, both in the organ of central immunogenesis and in the organs of the peripheral immune system – the spleen and lymph nodes and intra-organ lymph formations). During histological studies, the structure of cells and tissues, when using a mineral adaptogen, was more morphologically mature and was in a functionally active state, and dystrophic and necrotic processes were observed in the control group. The conducted studies convincingly prove the effect of mineral adaptogen on increasing natural resistance and its immunoprotective properties. Scientific novelty. For the first time in experimental conditions, a simultaneous assessment of the immunobiochemical parameters of the blood of laboratory animals and a microscopic examination of the organs of the immune system at all levels with morphometric analysis of the data obtained were given. As a result of the conducted studies, the immuno- and organoprotective effect of feeding the mineral adaptogen was proved and the immunomodulatory effect was morphometrically confirmed.

An important direction in the improvement of veterinary and prophylactic measures is the development and introduction into production of new preparations having bioactive properties and regulatory influence on the growth and development of birds, the intensity of metabolic processes, the ability to enhance the functional activity of organs and systems of the body, increase the level of natural resistance of the organism animals. The purpose of research was to study the effect of nanomicroelement feed additive «Microstimulin» and means Bioglobin on the resistance and metabolism of chicken broilers at experimental pseudomonosis. The investigated means «Microstimulin» and Bioglobin were given to chickens aged 14 days (cross Cobb 500) per os 1 time per day in a dose of 1 ml/l and 1 ml/kg with drinking water for 14 days. At day 12 of the experiment, we infected chickens with culture P. aeruginosa intraperitoneally at a dose of 300,000 CFU/ml to modeled pseudomonas infection groups. Slaughter of chickens was carried out in accordance with the principles of humanity by decapitation method on the 15th day of the experiment in 29 day old chicks. The determination of action of the «Microstimulin» and Bioglobin on biochemical processes in the organism of conditionally healthy poultry and at experimental pseudomonas infection was carried out in a complex manner, based on the indicators of congenital immunity, protein metabolism and activity of hepatospecific enzymes AST and ALT. The «Microstimulin» and Bioglobin has a pronounced influence on metabolic processes, in particular protein metabolism, and on the state of the system of congenital immunity of poultry. In the organism of intact bird, investigated means causes similar changes in the level of such mediators of the immune response, as CIC average molecular weight and seromucoids. The use of «Microstimulin» induces pronounced changes in the level of the protein through increased globulin fractions, and increased lysozyme activity. The action of Bioglobin is accompanied by a redistribution of protein fractions towards a slight increase in the synthesis of albumin and γ-globulin, the accumulation of the protein metabolism fractions in the serum, and an increase of lysozyme activity. The investigated means also helps to reduce the manifestations of pathogenetic effects of P. aeruginosa on the bird organism.

The widespread worldwide spread of acute respiratory diseases is an urgent problem in health care. Expressed polyetiology of respiratory diseases does not allow to limit the use of specific vaccine preparations and dictates the need to use to combat them a variety of non-specific means that stimulate the natural resistance of the human body. The main pharmacological action of sodium deoxyribonucleate is the stimulation of phagocytic activity of T-helpers and T-killers, increasing the functional activity of neutrophils and monocytes/ macrophages, providing regeneration and repair processes in the epithelial component of antiviral protection of the body. Based on the above, the study of the clinical efficacy of Derinat® in the form of spray in the treatment of acute respiratory viral infections is relevant.

WHO declared Covid 19 /SARS -COV-2 as a global pandemic.Till date, there is no medicine for COVID-19. If the Infection arises in the body then the defence mechanism activated against infection. A recent study suggests that temporarily augmenting the body's immune system in the early stages of COVID-19 can help patient to avoid severe symptoms as it is rightly said prevention is better than cure. Ayurveda approaches to develop physiological reactions to facilitate immunity. Planning of diet is most important to boost immunity.As per many researches to provide supplementary food which contains Zinc, Vitamin C,Vitamin D and immunity boosting foodsuch as citrus natural products, custard apple, apple, papaya is among the Fruits. Vegetables include broccoli, onion, garlic and green leafy vegetables. Nuts, ginger, turmeric, pepper, egg yolk, shellfish, mushroom. The need of the hour is a quick boost to immune system to keep it fit, fighting. One should get the right amount of nutrients from the diet, supplementation regimen to boost immune system.In this review, there are few common supplements and super food studies have been included.

Nutritional Recommendation

It is the most unreliable truth that anybody can get infected by the COVID-19, and nobody can escape from the danger of getting tainted by the virus. Yet, the line of hope is that anyone and everyone can boost their resistance, thus avoid the risk of getting affected by the illness. The immunity of humans pulls down as they grow older. If their immune system is robust, them falling sick is feeble. If their resistance is weak, them getting ill is sound. Several factors affect the immune system and its ability, including its nourishment. A two-way connection between nutrition, infection and immunity presents. Changes in one part will affect the others part in our body that's the nature's rule. Well defined immune system quality which is present between each life phase may influence the type, generality and the degree of infections. At the same time, low nutrition to the body will decrease the immune function and expose the body to the danger of getting infected by infectious diseases. Different quantity of micronutrients is required for increasing the immunity power of our body. Generally the vitamins A,C,D,E,B2,B6,B12, iron, zinc and selenium.The deficiencies of micronutrients are acknowledged as a global health issue, and also low nutrition makes it prone to establishes the infections in the body.
