Paenibacillus larvae is Gram-positive, spore-forming, rod-shaped bacteria. This pathogen threatens one of the most considerable worldwide pollinators - the honeybee (Apis mellifera). It is causative agent of bee disease called American foulbrood. Although it affects only bee larvae, preferably on the first day of its live, it is highly contagious and could quickly destroy whole bee colony. Adult bees are not susceptible to infection, however due to huge spores resilient of P. larvae, they perform the role of main disease vector. Also the careless beekeepers make it easier to spread. Bee diseases are enquired by state veterinary administration, because honeybee is classified as a livestock. If disease evolves to clinic phase, infected bees and hive with all tools must be burned. American foulbrood is one of the most deleterious bee diseases. This bachelor thesis discuss about problems of whole disease and it is focused on the interactions between bacteria Paenibacillus larvae, hymenoptera insect honeybee and human factor presented by beekeepers, state veterinary administration and corresponding laws. Key words: Paenibacillus larvae, American Foulbrood, entomopathogenic bacteria, Apis mellifera, honeybee
