Abstract

A novel rickettsial agent, ‘Candidatus Rickettsia asembonensis’ strain NMRCii, was isolated from cat fleas, Ctenocephalides felis, from Kenya. Genotypic characterization of the new isolate based on sequence analysis of five rickettsial genes, rrs, gltA, ompA, ompB and sca4, indicated that this isolate clustered with Rickettsia felis URRWXCal2. The degree of nucleotide similarity demonstrated that isolate NMRCii belongs within the genus Rickettsia and fulfils the criteria for classification as a representative of a novel species. The name Rickettsia asembonensis sp. nov. is proposed, with NMRCii (=DSM 100172=CDC CRIRC RAS001=ATCC VR-1827) as the type strain.
