Paenibacillus larvae Med-540, 846

Paenibacillus larvae Med-540, 846 is a Gram-positive bacterium primarily associated with the habitats of beehives, including the gut of honeybees (Apis mellifera), hive debris, and the broader Apinae and Anthophila host groups. This organism is a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen, and it exhibits a rod shape along with mobility capabilities. Notably, P. larvae Med-540, 846 is recognized as the causative agent of American foulbrood (AFB), a severe bacterial disease affecting honeybee brood. The disease poses significant risks to bee populations and can lead to devastating impacts on beekeeping operations. The bacterium has been documented in two distinct replicons, with accessions CP019687.1 and CP019651.1 providing genetic information for further research. Understanding the ecological role and pathogenic potential of Paenibacillus larvae Med-540, 846 is crucial for bee health management. The presence of this bacterium in beehives underlines the importance of monitoring and controlling AFB to mitigate its spread and impact on honeybee colonies. This highlights the intricate relationship between microbial inhabitants and the health of bee populations in their natural habitats.
