Neorickettsia risticii str. Illinois

Names Neorickettsia risticii str. Illinois
Accession numbers NC_013009
Background Neorickettsia risticii is an obligate intracellular bacterium of trematodes and mammals. Horses develop Potomac horse fever (PHF) an acute, often severe to fatal systemic disease when they ingest aquatic insects containing encysted N. risticii-infected trematodes (flukes). PHF is frequently found throughout North America and increasingly recognized in South America. The relationship of N. risticii with its trematode host seems to be either commensal or mutualistic, as reproduction of trematodes does not appear to be adversely affected by infection. Four-way comparison of genes among N. risticii and other Anaplasmataceae showed that most genes are either shared among Anaplasmataceae (525 orthologs that generally associated with housekeeping functions), or specific to each genome (>200 genes that are mostly hypothetical proteins) (adapted from PMID 19661282).
