Genetic variability and phylogeographic relations of Nosema Apis at the apiary level
... genetic diversity of the microsporidian Nosema apis, the causative agent of nosemosis in honey bees (Apis mellifera), are presented using the example of a single apiary located in the Laishevsky District of the Republic of Tatarstan. Identification of the haplotypic composition of the pathogen and assessment of its phylogeographic relationships with Eurasian isolates were carried out based on the polymorphism of the polar tube protein gene PTP3. It was established that all examined bees were infected with ...
