Nocardia inohanensis sp. nov., Nocardia yamanashiensis sp. nov. and Nocardia niigatensis sp. nov., isolated from clinical specimens

Int J Syst Evol Microbiol. 2004 Mar;54(Pt 2):563-569. doi: 10.1099/ijs.0.02794-0.


Comparative 16S rDNA studies on six strains of actinomycete isolated from clinical specimens revealed that they belong to the genus Nocardia and are closely related to Nocardia seriolae, Nocardia otitidiscaviarum, Nocardia uniformis, Nocardia pseudobrasiliensis and Nocardia crassostreae. However, the novel organisms consistently formed a clade distinct from that of the five latter species. Determination of DNA-DNA relatedness indicated that these strains could be classified under three novel species. Based on their phenotypic and phylogenetic characters, three novel species of the genus Nocardia are established: Nocardia inohanensis sp. nov. for IFM 0092(T) (=NBRC 100128(T)=JCM 11891(T)=DSM 44667(T)), Nocardia yamanashiensis sp. nov. for IFM 0265(T) (=NBRC 100130(T)=JCM 11893(T)=DSM 44669(T)) and Nocardia niigatensis sp. nov. for IFM 0330(T) (=NBRC 100131(T)=JCM 11894(T)=DSM 44670(T)), IFM 0260, IFM 0636 and IFM 0833.
