A frame of brood that is not so healthy. The white stuff in cells are chalkbrood mummies. This colony is probably infected with chalkbrood, possibly also brood disease (AFB or EFB), and perhaps also varroa mites. When varroa mite infection is severe, it often causes frames like this, which is called bee PMS (parasitic mite syndrome). Photo by Prof. M.V. Smith, University of Guelph.
