Microsporidia comprise a phylum of obligate intracellular pathogens related to fungi. Microsporidia Nematocida sp1 strain ERTm6 was isolated from wild-caught Caenorhabditis briggsae and causes a lethal intestinal infection in Caenorhabditis nematodes. We report the genome sequence of N. sp1 ERTm6, which will facilitate study of the Nematocida genus and other Microsporidia. FOOTNOTES Address correspondence to Christina A.
