What is American foulbrood?
American foulbrood (AFB) is a highly infectious brood disease, caused by the the bacterium Paenibacillus larvae. This bacterium develops in young larvae of the honey bee, causing their premature death. Adult bees are not harmed by the bacterium. Infected larvae can be detected and removed by the workers. If the infestation level increases, however, colonies can be damaged. The bacterium forms spores, which are resistant to a wide variety of environmental conditions for a long period of time. In this form the disease gets transmitted to other colonies. The most urgent measure during an outbreak is therefore the removal and destruction of infected brood, as well as the disinfection of all potentially contaminated objects (hives, equipment). In extreme cases, the colonies must be destroyed.
