Abstract Background The highly compacted 2.9-Mb genome of Encephalitozoon cuniculi placed the microsporidia in the spotlight encoding a mere 2 000 proteins and a highly reduced suite of biochemical pathways. This extreme level of reduction is not universal across the microsporidia with genomes known to vary up to sixfold in size suggesting that some genomes may harbor a gene content that is not as reduced as that of Enc. cuniculi. In this study we present an in-depth survey of the large genome of Octosporea bayeri a pathogen of Daphnia magna with an estimated genome size of 24 Mb in order to shed light on the organization and content of a large microsporidian genome.
