Abstract

Two Gram-stain-negative, non-endospore-forming, rod-shaped bacteria, strains CC-MHSW-5(T) and A1392, were isolated from water of coastal hot springs located in Taiwan and China, respectively, and investigated for their taxonomic position. The two strains shared identical 16S rRNA gene sequences, a DNA-DNA hybridization value >80% and similar genomic DNA G+C contents (64.3 and 64.6 mol%), but showed different genomic fingerprint patterns generated by BOX-PCR and three random amplification polymorphic DNA PCRs. The strains shared highest 16S rRNA gene sequence similarities with the type strains of Chelativorans multitrophicus (96.7 and 96.1%), Thermovum composti (96.2 and 96.1%) and Chelativorans oligotrophicus (96.1 and 95.8%). Phylogenetic trees (based on 16S rRNA and recA gene sequence comparisons) showed a distinct clustering of both strains with the type strains of species of the genus Chelativorans and T. composti Nis3(T). The quinone systems of strains CC-MHSW-5(T) and Nis3(T) contained ubiquinone Q-10 as the major component. The major polyamine in both strains was sym-homospermidine. Putrescine, spermidine and, for strain CC-MHSW-5(T), spermine were found in minor concentrations. Their polar lipid profiles consisted of ph...Continue Reading

Cavernous Hemangioma

Cavernous hemangioma is a blood vessel defect or benign tumor that leads to leakage of blood to the surrounding tissues. This can occur in several organs including the brain, which can lead to seizures. Discover the latest research on cavernous hemangiomas here.
