TLDR
Ulastructural analysis, comparative sequence analysis, and determination of the whole genome sequence confirmed the relatedness of the new isolate to members of the Chlamydiaceae, while, at the same time demonstrating a unique position outside the currently recognized species of this family.Abstract:
Investigations conducted on feral African Sacred Ibises (Threskiornis aethiopicus) in western France led to the isolation of a strain with chlamydial genetic determinants. Ultrastructural analysis, comparative sequence analysis of the 16S rRNA gene, ompA, and of a concatenate of 31 highly conserved genes, as well as determination of the whole genome sequence confirmed the relatedness of the new isolate to members of the Chlamydiaceae, while, at the same time demonstrating a unique position outside the currently recognized species of this family. We propose to name this new chlamydial species Chlamydia ibidis.read more

TL;DR: Comparative genome analysis involving the type strains of currently accepted Chlamydiaceae species and the designated type strains representing the two new clades confirmed that the latter could be classified into two different species as their average nucleotide identity (ANI) values were always below 94%, both with the closest relative species and between themselves.

Emendation of the family Chlamydiaceae: Proposal of a single genus, Chlamydia, to include all currently recognized species

TL;DR: All 11 currently recognized Chlamydiaceae species are proposed in a single genus, the genus Chlamydia, because no easily recognizable phenotype such as host preference or tissue tropism is available that would support a subdivision.

A Review on Chlamydial Diseases in Animals: Still a Challenge for Pathologists?
TL;DR: The historical background and the most important developments in the field of animal chlamydial research in the past 5 years with a special focus on pathology are summarized, the current nomenclature is summarized, critical thoughts about diagnostics are presented, and an update on chlamYDial infections in domesticated animals such as livestock, companion animals and birds are given.

Chlamydia gallinacea, not C. psittaci, is the endemic chlamydial species in chicken (Gallus gallus)
TL;DR: This study indicates that C. gallinacea is the endemic chlamydial species in chickens, whereas C. psittaci dominates only in pigeons, and further studies are required to address the specific conditions under which C.gallinacea could act as an avian pathogen and possibly also a zoonotic agent.
Type III Secretion, Contact-Dependent Model For The Intracellular Development of Chlamydia
TL;DR: In this paper, the authors present a mathematical model for the modulation of Chlamydia's developmental events involving the contact-dependent type III secretion (TTS) system, which is a class of obligate intracellular bacterial pathogens that replicate within vacuoles in host eukaryotic cells termed inclusions.

Emended description of the order Chlamydiales, proposal of Parachlamydiaceae fam. nov. and Simkaniaceae fam. nov., each containing one monotypic genus, revised taxonomy of the family Chlamydiaceae, including a new genus and five new species, and standards for the identification of organisms.
TL;DR: A reclassification of the order Chlamydiales and its current taxa is proposed in this article, which retains currently known strains with > 90% 16S rRNA identity in the family Chlamdianaceae and separates other chlamydia-like organisms that have 80-90% 16s rRNA relatedness to the chlamydiaceae into new families.

TL;DR: An automated pipeline for phylogenomic analysis (AMPHORA) is developed that overcomes the existing bottlenecks limiting large-scale protein phylogenetic inference and demonstrates its high throughput capabilities and high quality results.
