Paenibacillus larvae 04-309

Paenibacillus larvae 04-309 is a Gram-positive bacterium primarily associated with beehives, specifically inhabiting the gut of honeybees and hive debris. This species is classified as a facultative anaerobe, indicating its ability to thrive in both aerobic and anaerobic environments. The bacterium exhibits a rod shape and possesses mobility, allowing it to navigate its habitat effectively. One of the most significant health implications of Paenibacillus larvae 04-309 is its role as the causative agent of American foulbrood (AFB), a serious bacterial disease affecting honeybee brood. This disease poses a considerable threat to bee populations and, consequently, to the health of ecosystems reliant on these pollinators. The bacterium is primarily associated with hosts in the Apinae subfamily, including Apis mellifera (the Western honeybee) and other members of the Anthophila clade. Genomic data indicate that Paenibacillus larvae 04-309 contains three replicons, which may contribute to its adaptability and virulence in the hive environment. Accessions for this strain include CP019652.1, CP019653.1, and CP019654.1, which provide valuable genetic information for further research. The ecological insight derived from the presence of Paenibacillus larvae 04-309 highlights the importance of monitoring and managing this bacterium within beekeeping practices, as its pathogenicity can lead to significant declines in honeybee populations, impacting pollination and biodiversity in various ecosystems.
