Borrelia carolinensis – a new species

Excerpt:
A group of 16 isolates with genotypic characteristics different
from those of known species of Borrelia burgdorferi sensu lato
(sl) complex were cultured from ear biopsies of the rodents
Peromyscus gossypinus and Neotoma floridana trapped at 5
localities in South Carolina, United States. Multilocus sequence
analysis involving 16S rRNA, 5S-23S (rrf-rrl) intergenic spacer
region, flagellin, ospA and p66 genes was used to clarify the
taxonomic status of the new group of B.
burgdorferi sl isolates. Phylogenetic analysis based on
concatenated sequences of 5 analyzed genomic loci showed that the
16 isolates clustered together but separately from the other
species in the B. burgdorferi sl complex. The analyzed group
therefore represents a new species, for which the name Borrelia
carolinensis was proposed, with the type strain Borrelia
carolinensis strain SCW-22T (=ATCC BAA-1773T =DSMZ 22119 T).
Multilocus sequence analysis of new species was conducted and
published previously. Here we present the formal description of
Borrelia carolinensis sp. nov., isolated from rodents and tick
from southeastern United States.
