ABSTRACT
objective To identify the three strains of pink-pigmented bacteria isolated from ticks.Methads 16S rDNA sequence analysis,16S rDNA similarity searching,bacterial morphological,physiological and biochemical tests and fatty acids analysis were used.Results The bacterial strains were pinkpigment,gram negative,strictly aerobic coccobacillus.They grow optimally at 37℃,while not in the presence of≥5% NaCl.The tests showed positive result for urease,D-glucose,citrate,UV absorption,and catalase.The predominant fatty acids were C160,C170,C181 ωgc and C190 cyc.Comparative 16S rDNA sequences analysis revealed that the strains were closely related to Roseomonas cervicalis and could reach up to 99.1% identity.Conclusion Based on phenotypic,biochemical and phylogenetic data,we propose these three isolates represent distinct species in genus Roseomonas,of which ticks may serve as a potential vector.
