Larvae showing typical Europeal foulbrood (EFB) symptoms. These larvae die earlier than those of AFB, while the larvae are still coiled (AFB larvae die in straight, upright position.) and show yellow streaks first which then turn brown. Caused by a baterium Melissococcus pluton (formerly Streptococcus pluton). Photo by M.V. Smith, University of Guelph.
