Species identification and phylogenetic relationships based on partial HSP60 gene sequences within the genus Staphylococcus.
The phylogenetic relationships among 36 validly described species or subspecies within the genus Staphylococcus were investigated by cloning and sequencing their 60 kDa heat-shock protein (HSP60) genes using a set of universal degenerate HSP60 PCR primers. The cloned partial HSP60 DNA sequences from nine Staphylococcus aureus strains were highly conserved (97-100% DNA sequence similarity; mean ...
متن کاملrpoB gene sequence-based identification of Staphylococcus species.
The complete sequence of rpoB, the gene encoding the beta subunit of RNA polymerase was determined for Staphylococcus saccharolyticus, Staphylococcus lugdunensis, S taphylococcus caprae, and Staphylococcus intermedius and partial sequences were obtained for an additional 27 Staphylococcus species. The complete rpoB sequences varied in length from 3,452 to 3,845 bp and had a 36.8 to 39.2% GC con...
متن کاملGenus-specific polymerase chain reaction for the mycobacterial dnaJ gene and species-specific oligonucleotide probes.
Identification of tuberculous and nontuberculous mycobacteria by biochemical methods is a long-term process that takes up to 8 weeks for completion and requires expertise to interpret the results. In order to detect and differentiate the major pathogenic mycobacterial species, we developed genus-specific primers that amplify the dnaJ gene from the broad spectrum of mycobacterial species and det...
متن کاملHyphal wall protein 1 gene: A potential marker for the identification of different Candida species and phylogenetic analysis
Background and Purpose: Hyphal wall protein 1 (HWP1) is an important adhesin which usually is expressed on the germ tube and hyphal surface produced by different Candida species. The hyphal wall protein-coding gene (HWP1) was evaluated as a novel identification and phylogenetic marker in Candida tropicalis, C. orthopsilosis, C. parapsilosis and C. glabrata. Materials and Methods: Initially, fo...
متن کاملMycobacterium species identification--a new approach via dnaJ gene sequencing.
The availability of the dnaJ1 gene for identifying Mycobacterium species was examined by analyzing the complete dnaJ1 sequences (approximately 1200 bp) of 56 species (54 of them were type strains) and comparing sequence homologies with those of the 16S rRNA gene and other housekeeping genes (rpoB, hsp65). Among the 56 Mycobacterium species, the mean sequence similarity of the dnaJ1 gene (80.4%)...
