teria and their relatives,” are a major class of bacteria (Gupta, 2000; Holt et al., 1994; Stackebrandt et al., 1988; Zinder, 1998). This group of predominantly Gram-negative bacteria contains more than 200 genera with a great diversity of phenotypic and physiological attributes. Proteobacteria have been classified based on homology of 16S ribosomal RNA or by hybridization of ribosomal RNA or D...
Several characteristics of the 16S rRNA gene, such as its essential function, ubiquity, and evolutionary properties, have allowed it to become the most commonly used molecular marker in microbial ecology. However, one fact that has been overlooked is that multiple copies of this gene are often present in a given bacterium. These intragenomic copies can differ in sequence, leading to identificat...
In the current work, we describe genome diversity and core genome sequences among representatives of three bifidobacterial species, i.e., Bifidobacterium adolescentis, Bifidobacterium catenulatum, and Bifidobacterium pseudocatenulatum, by employing a polyphasic approach involving analysis of 16S rRNA gene and 16S-23S internal transcribed spacer (ITS) sequences, pulsed-field gel electrophoresis ...
