In a two-year period during 2020-2021, 185 bee samples were tested. All samples were examined by morphological and light microscopic methods. The obtained results showed that 32.43% of bee samples were infested with Varroa destructor. The degree of infection in the bees ranged from 0.5% to 60%. Spores of Nosema spp. were established in 25.40% of samples with a degree of invasion in the range from 3x105 to 26x106 per bee. Mixed infections of both parasites were observed in 32.43% of the samples. Negative samples were with the lowest value of 9.74%. Keywords : Honey bee Bee pathogens Infestation rate Bulgaria
