Members of Chlamydiaceae have been extensively characterized by complete genome
sequencing. This information provides new understanding concerning their natural …

Analyses of genome sequences, by some approaches, suggest that the widespread
occurrence of horizontal gene transfers (HGTs) in prokaryotes disguises their evolutionary …

Chlamydia trachomatis is a leading cause of genital and ocular infections for which no
vaccine exists. Upon entry into host cells, C. trachomatis resides within a membrane-bound …

The species of Clostridium comprise a very heterogeneous assemblage of bacteria that do
not form a phylogenetically coherent group. It has been proposed previously that only a …

The Actinobacteria constitute one of the main phyla of Bacteria. Presently, no morphological
and very few molecular characteristics are known which can distinguish species of this …

The class Gammaproteobacteria, which forms one of the largest groups within bacteria, is
currently distinguished from other bacteria solely on the basis of its branching in …

The phylum Chlamydiae contains obligate intracellular bacteria, several of which cause
disease in their hosts. Morphological studies have suggested that this group of bacteria may …

Based on Darwin's concept of the tree of life, vertical inheritance was thought to be
dominant, and mutations, deletions, and duplication were streaming the genomes of living …

The PVC superphylum is an amalgamation of species from the phyla P lanctomycetes, V
errucomicrobia, and C hlamydiae, along with the Lentisphaerae, Poribacteria, and two other …

Abstract Background The Archaea are highly diverse in terms of their physiology,
metabolism and ecology. Presently, very few molecular characteristics are known that are …
