Abstract
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.
