The genome of the honey bee fungal pathogen Ascosphaera apis (the cause of chalkbrood in honey bees) has been sequenced and annotated in draft form (Qin et al., 2006, Insect Molecular Biology 15:715-718) at the Baylor College of Medicine Human Genome Sequencing Center. Sequence data and gene prediction tracks for this species, for the honey bee bacterial pathogen Paenibacillus larvae (the cause of American foulbrood in honey bees, Qin et al., ibid.) and the microsporidial pathogen Nosema ceranae (Cornman et al., PLoS Pathog. 2009 Jun;5(6):e1000466) are available at the US National Institutes of Health-NCBI Genome Project sites and via the Beebase Honey Bee Pathogen server,


Data are free for public use without restrictions. All three microbial sequencing projects are ongoing at several institutions, for recent updates, contact Jay Evans (USDA/ARS Beltsville, MD, jay.evans@ars.usda.gov).
