First report on isolation and characterization of Bacillus Sp. associated with honey bee brood disease Abstract Bacterial infections in honey bee brood pose a significant threat to bee populations, leading to decreased honey production and disrupting critical crop pollination networks. While Paenibacillus larvae and Melissococcus plutonius are well-established as major pathogens of honey bee eggs and larvae, the presence of other harmful bacteria in the Khyber Pakhtunkhwa (KPK) province of Pakistan remains largely unexplored. Molecular characterization of Bacillus species and B. cereus isolates revealed the presence of key virulence genes, including the cry gene, known for its insecticidal properties. The ability of B. cereus to produce cytotoxins, haemolysins, and enterotoxins raises concerns about its impact on larval immunity and survival. Similarly, B. mycoides , a close relative of...
Honeybee colonies decline in East Tennessee as officials research causes U.S. Department of Agriculture is currently working with multiple colleges and nonprofits to identify the potential causes of a steep decline in honey colonies. According to a recent study, over 60% of commercial colonies, and over 50% of hobbyist colonies have declined this year. Michael Keaton of Dandridge said he has never seen bee colonies dwindle so fast in his five years of beekeeping “It is sad if you care about anything and care about life on earth when a colony dies,” said Keaton. According to the USDA, about 35% of the world’s food crops depend on pollinators to reproduce. Keaton said cutting off bee’s food supply by mowing, chopping down trees, or the use of pesticides could be contributing to the decline. “I only lost two hives, I lost like 2% of mine, and a lot of people across the U.S. have lost up to 60%.” he said. While many beekeepers in the commu...
