Interpretive Summary: Nosema disease is persistent in honey bee colonies and has been linked with colony declines. Here we present a complete genome sequence for Nosema ceranae, the most common nosema parasite in the United States. The genome provides insights into Nosema biology and possible control strategies for this parasite, improving the management tools for honey bee health.
Technical Abstract: Microsporidia comprise a phylum of single cell, intracellular parasites and represent the earliest diverging branch in the fungal kingdom. The microsporidian parasite Nosema ceranae primarily infects honey bee gut epithelial cells, leading to impaired memory and suppressed immune responses. We here sequenced and annotated the N. ceranae genome to obtain insight into the pathogenesis and evolution of this microsporidian species. We present a robust 8.8Mbp genome assembly of 2280 protein coding genes, which were 100% expressed during a parasite life cycle. N. ceranae encodes a high number of genes involved in transporting nutrients and energy, as well as drug resistance, when compared with sister species Nosema apis. Our results provide new insights into the pathogenesis of N. ceranae and a blueprint for treatment strategies which target this parasite without harming honey bees. The unique infectious apparatus and transportation pathway members can help to identify treatments to control this parasite.
