🔬 A bacterial infection can destroy entire bee colonies – the causative agent is the spore-forming bacterium 𝙋𝙖𝙚𝙣𝙞𝙗𝙖𝙘𝙞𝙡𝙡𝙪𝙨 𝙡𝙖𝙧𝙫𝙖𝙚. 𝘗𝘢𝘦𝘯𝘪𝘣𝘢𝘤𝘪𝘭𝘭𝘶𝘴 𝘭𝘢𝘳𝘷𝘢𝘦 causes American foulbrood, a notifiable disease affecting honeybee larvae. Infection begins when bee larvae ingest bacterial spores while feeding. In the larval midgut, the spores germinate, and the vegetative cells penetrate the gut epithelium. The bacteria then multiply within the larval body cavity and produce new spores. Infected larvae eventually die and form a characteristic foulbrood scale, a dark mass containing large numbers of spores. Typical signs of infection include:  - sunken or perforated brood caps  - dark larval remains in cells  - irregular brood patterns The high resistance of the spores facilitates the spread of the disease within and between colonies. 📚 More background information on 𝘗𝘢𝘦𝘯𝘪𝘣𝘢𝘤𝘪𝘭𝘭𝘶𝘴 𝘭𝘢𝘳𝘷𝘢𝘦 can be found in 𝗟𝗦-𝗽𝗲𝗱𝗶𝗮 – 𝗼𝘂𝗿 𝗘𝗻𝗰𝘆𝗰𝗹𝗼𝗽𝗲𝗱𝗶𝗮 𝗼𝗳 𝗟𝗶𝘃𝗲𝗱 𝗠𝗶𝗰𝗿𝗼𝗯𝗶𝗼𝗹𝗼𝗴𝘆. #lspedia #Paenibacilluslarvae #LifeSciences
