Cell wall precursors are required to organize the chlamydial division septum. [PDF]

open access: yes, 2014
Members of the Chlamydiales order are major bacterial pathogens that divide at mid-cell, without a sequence homologue of the FtsZ cytokinetic tubulin and without a classical peptidoglycan cell wall.

The ribonuclease E regulator RebA is essential for diazotrophic growth in the cyanobacterium Anabaena PCC 7120

open access: yesmLife, Volume 4, Issue 5, Page 516-526, October 2025.
Abstract Ribonuclease E (RNase E) is central to bacterial RNA metabolism. In cyanobacteria, its activity is inhibited by RebA, a key mechanism for controlling cell morphology. Here, we demonstrate that rebA is essential for diazotrophic growth of Anabaena PCC 7120, a filamentous cyanobacterium capable of forming heterocysts—specialized nitrogen‐fixing ...

Architecture and host interface of environmental chlamydiae revealed by electron cryotomography [PDF]

open access: yes, 2014
Chlamydiae comprise important pathogenic and symbiotic bacteria that alternate between morphologically and physiologically different life stages during their developmental cycle.

Analysis of polymorphic membrane protein expression in cultured cells Identifies PmpA and PmpH of Chlamydia psittaci as candidate factors in pathogenesis and immunity to infection [PDF]

open access: yes, 2016
The polymorphic membrane protein (Pmp) paralogous families of Chlamydia trachomatis, Chlamydia pneumoniae and Chlamydia abortus are putative targets for Chlamydia vaccine development. To determine whether this is also the case for Pmp family members of C.

Structural insights into the Pseudomonas aeruginosa ClpP1•ClpP2 heterocomplex and its interactions with the AAA+ ClpX unfoldase

open access: yesProtein Science, Volume 34, Issue 10, October 2025.
Abstract ClpXP and other AAA+ proteases play central roles in bacterial proteostasis by degrading misfolded and regulatory proteins. In Pseudomonas aeruginosa, ClpXP consists of the ClpX unfoldase and ClpP peptidase, which influence critical adaptive processes contributing to stress resistance. P.

Commonly prescribed β-lactam antibiotics induce C. trachomatis persistence/stress in culture at physiologically relevant concentrations.

open access: yesFrontiers in Cellular and Infection Microbiology, 2014
Chlamydia trachomatis, the most common bacterial sexually transmitted disease agent worldwide, enters a viable, non-dividing and non-infectious state (historically termed persistence and more recently referred to as the chlamydial stress response) when ...

Early MicroRNA expression profile as a prognostic biomarker for the development of pelvic inflammatory disease in a mouse model of chlamydial genital infection [PDF]

open access: yes, 2014
It is not currently possible to predict the probability of whether a woman with a chlamydial genital infection will develop pelvic inflammatory disease (PID).

The Impact of Whole‐Animal Fluid Preservation on the Observed Gut Microbiome of Vertebrates: Implications for the Use of Museum Specimens in Microbiome Research

open access: yesMolecular Ecology Resources, Volume 25, Issue 7, October 2025.
ABSTRACT The vertebrate gut houses diverse microbial communities that provide insights into their host's ecological and evolutionary histories. Nevertheless, microbiome research has not been distributed equally across host taxonomy, geography and timescales. The millions of fluid‐preserved specimens stored in natural history museums worldwide represent

In Situ Impact of Waste Polyethylene (PE) Films on Soil Quality and Plant Growth in Agricultural Soil

open access: yesLand Degradation &Development, Volume 36, Issue 14, Page 5054-5065, 30 August 2025.
ABSTRACT Plastic films have accumulated in soil ecosystems over decades of agricultural activities. These films potentially disrupt the soil structure, hinder nutrient cycling, and deteriorate soil quality. However, there is still a substantial knowledge gap in understanding how real‐world waste polyethylene films (WPEFs), with varied shapes and sizes,

An Ancient Molecular Arms Race: Chlamydia vs. Membrane Attack Complex/Perforin (MACPF) Domain Proteins

open access: yesFrontiers in Immunology, 2020
Dynamic interactions that govern the balance between host and pathogen determine the outcome of infection and are shaped by evolutionary pressures. Eukaryotic hosts have evolved elaborate and formidable defense mechanisms that provide the basis for ...
