Genomic analysis of the population structure of Paenibacillus larvae in New Zealand

Frontiers in Microbiology, 2023
New Zealand is a remote country in the South Pacific Ocean. The isolation and relatively late arrival of humans into New Zealand has meant there is a recorded history of the introduction of domestic species. Honey bees (Apis mellifera) were introduced to

Distribution and transmission of American foulbrood in honey bees [PDF]

, 2006
The distribution of Paenibacillus larvae spores, the causative agent of American foulbrood, was studied on three different levels in the honey bee system; the apiary level, the colony level and the individual honey bee level. The increased understanding of spore distribution has been used to give recommendations regarding sampling of adult honey bees ...

Powdered Sugar Examination as a Tool for the Assessment of Paenibacillus larvae Infection Levels in Honey Bee Colonies

Frontiers in Veterinary Science, 2022
American Foulbrood (AFB) is a contagious and severe brood disease of honey bees caused by the spore-forming bacterium Paenibacillus larvae. The identification of honey bee colonies infected by P. larvae is crucial for the effective control of AFB.
