Nosematosis belongs to the intestinal disease of bees, which is widely spread both in the world and in the Czech Republic. It is caused by Nosema apis and Nosema ceranae. The aim of this diploma thesis was to evaluate the occurrence of the Nosema dispute in the territory of ČSV Bystřice, to describe species variability and to assess the effect of the season on the occurrence of Nosema apis and Nosema ceranae. To detect infection of colonies, 5 bees from selected hives were examined under the microscope. In positive specimens on nosematosis, the species of Nosema spore was molecularly examined. In total, 93 samples from 15 breeders were examined. Samples were taken in the spring and summer of 2017. The sampling took place both for malachists and for farmers with more than 150 bee colonies. During the summer sampling more positive bees were found than in spring sampling. Beekeepers were further assessed by the number of hives. Following the analysis of the samples obtained using the PCR method, Nosema ceranae disputes were present in the vast majority of colonies.
