Abstract |
Four novel Gram-negative, mesophilic, aerobic, motile, and
cocci-shaped strains were isolated from tick samples (strains
546T and 573) and respiratory tracts of marmots (strains 1318T
and 1311). The 16S rRNA gene sequencing revealed that strains
546T and 573 were 97.8% identical to Roseomonas wenyumeiae
Z23T, whereas strains 1311 and 1318T were 98.3% identical
to Roseomonas ludipueritiae DSM 14915T. In addition,
a 98.0% identity was observed between strains 546T and 1318T.
Phylogenetic and phylogenomic analyses revealed that strains
546T and 573 clustered with R. wenyumeiae Z23T, whereas
strains 1311 and 1318T grouped with R. ludipueritiae DSM
14915T. The average nucleotide identity between our isolates
and members of the genus Roseomonas was below 95%. The
genomic G+C content of strains 546T and 1318T was 70.9% and
69.3%, respectively. Diphosphatidylglycerol (DPG) and phosphatidylethanolamine
(PE) were the major polar lipids, with
Q-10 as the predominant respiratory quinone. According to
all genotypic, phenotypic, phylogenetic, and phylogenomic
analyses, the four strains represent two novel species of the
genus Roseomonas, for which the names Roseomonas haemaphysalidis
sp. nov. and Roseomonas marmotae sp. nov. are
proposed, with 546T (= GDMCC 1.1780T = JCM 34187T) and
1318T (= GDMCC 1.1781T = JCM 34188T) as type strains,
respectively. |
