Candidiasis is a mycosis caused by the mycelial yeast of the Candida genus which is opportunistic pathogen of humans, animals, and birds. Under some conditions such as prolonged antibiotic therapy, overcrowding, and immunosuppression, the opportunistic Candida can cause disease. Chicken candidiasis is sporadically occurred and characterized by unsatisfactory growth, listlessness, roughness of feathers, and death. A case of 23 weeks old layer with history of increased mortality and anemia was submitted to our Lab. At necropsy, the characteristic lesions were observed in the crop and proventriculus. The whitish pseudomembrane, that are peeled easily, was found in the crop. Proventriculus was swollen and the mucosa was covered with hemorrhagic exudate. The histological changes of the affected crop are epithelial hyperplasia, hydropic degeneration, and mycelia formation. Smears made from the necrotic mucosal surfaces of the crop revealed the presence of large number of yeast cells and mycelia. Pure cultures of yeast colonies were obtained from the potato dextrose agar. The yeast cells were identified as Candida albicans by gene sequencing. To our knowledge, this is the first report of candidiasis in chickens with anemia in Korea.

Belarus concerns a biogeochemical province with the lowered content in environment of such microelements, as iodine, selenium, copper, cobalt, manganese, zinc and some other. It conducts to infringement of intensity and an orientation of processes of an exchange of proteins, carbohydrates, lipids, and finally - to decrease in their growth and development of an organism of young growth. High cost of foreign preparations for treatment and preventive maintenance of an alimentary anaemia, low bioavailability of iron and toxicity do not provide purposeful disesase control and immunodeficiencies arising on its background. The special urgency is got by research of means of complex preventive maintenance of an alimentary anaemia and immunodeficiencies. It has been established that the recipes N1-3 have proved to be non-toxic for laboratory animals and have no effect on the meat quality.

In the conditions of the Republic of Belarus there was realized the determination of efficiency of application of saline and chelate forms of copper and cobalt for treatment of anemic syndrome of cattle. It was found out that lack of copper and cobalt in cattle diets in the conditions of normal supply of iron could be a cause of cattle anemic syndrome. It took place because of the iron adsorption disorder in intestines and its inclusions in haem, as well as lowering of ehritropoztin synthesis. In the conditions of administration of copper and cobalt-containing preparations for animals there was noted the increasing of iron and haemoglobin content in blood. Administration of ethylene diamine tetraacetates of cobalt and copper made it possible to reduce considerably all evidences of clinical and laboratory symptoms of anemia and hypomicroelementosis in comparison with application of copper sulphate and cobalt.

In the conditions of the Republic of Belarus clinic and production conditions there was analyzed the prophylactic and therapeutic efficacy of a new national complex iron dextrane preparation Ferovital against deficiency (nutritional) anemia of new-born cattle and swine. In course of the study there were analyzed results of hematological and biochemical tests of blood of piglets which were administrated with Ferovital preparation. There were also marked the general economic index: live weight gain, disease incidence, piglet death rate, etc. Research results showed that the Ferovital preparation had an expressed prophylactic and therapeutic efficacy both in clinic and production conditions.
