Primary endosymbiosis: have cyanobacteria and Chlamydiae ever been roommates?

open access: yesActa Societatis Botanicorum Poloniae, 2014
Eukaryotes acquired the ability to process photosynthesis by engulfing a cyanobacterium and transforming it into a genuine organelle called the plastid. This event, named primary endosymbiosis, occurred once more than a billion years ago, and allowed the

Identification and characterization of a novel porin family highlights a major difference in the outer membrane of chlamydial symbionts and pathogens. [PDF]

open access: yesPLoS ONE, 2013
The Chlamydiae constitute an evolutionary well separated group of intracellular bacteria comprising important pathogens of humans as well as symbionts of protozoa.

Seasonal Dietary Changes Drive Adaptive Responses in the Gut Microbiota and Function of Myotis chinensis

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This research clarifies the synergistic adaptive interactions between seasonal foraging strategies and gut microbiome composition in Chinese chiropterans. Microbial diversity and community structure exhibit seasonal fluctuations, with functional metabolic pathways aligning to host reproductive cycles and hibernation physiology, thereby substantiating ...

Diversity of FAAL enzymes and prediction of their substrate specificity using FAALPred

open access: yesProtein Science, Volume 35, Issue 2, February 2026.
Abstract FAALs (fatty acyl‐AMP ligases) recruit and incorporate fatty acids during the biosynthesis of secondary metabolites. Their diversity, distribution, and substrate specificity remain poorly understood, which limits functional predictions from sequence data.

Evolutionary cell biology of division mode in the bacterial Planctomycetes-Verrucomicrobia-Chlamydiae superphylum

open access: yesFrontiers in Microbiology, 2016
Bacteria from the Planctomycetes, Verrucomicrobia and Chlamydiae (PVC) superphylum are exceptions to the otherwise dominant mode of division by binary fission, which is based on the interaction between the FtsZ protein and the peptidoglycan (PG ...

Age‐Specific Diagnostic Panorama Among People With Intellectual Disabilities in Comparison With the General Population: A Longitudinal Register Study (IDcare)

open access: yesJournal of Intellectual Disability Research, Volume 70, Issue 3, Page 295-315, March 2026.
ABSTRACT Background People with intellectual disabilities (ID) are known to have a higher risk for a wide range of health conditions compared to the general population. However, there is little research comparing a more comprehensive range of diseases and conditions at different ages.

Novel Preparation Method for Optimized Doxycycline‐Loaded Polycaprolactone Nanofibers

open access: yesNano Select, Volume 7, Issue 1, January 2026.
This study introduces a novel approach for obtaining polycaprolactone‐based nanofibers incorporating doxycycline. The optimal solvent mixture, enabling the simultaneous solubilization of polycaprolactone and doxycycline, is identified. The fiber diameter in drug‐loaded electrospun materials directly impacts drug release, bioavailability, and ...

The CrP operon of Chlamydia psittaci and Chlamydia pneumoniae [PDF]

open access: yesMicrobiology, 1995
One of the critical developmental events during the unique intracellular life cycle of Chlamydiae is their differentiation from a metabolically active, replicative form or reticulate body (RB) to an infectious extracellular form of the organism (elementary body or EB). This process is characterized by the expression of two extraordinarily cysteine-rich

Adding Guar Gum to High‐Fat Diets Ameliorates Fish Growth, Gut Histology, Gut Microbiota Composition, and Intestinal Inflammation in Common Carp

open access: yesAquaculture Nutrition, Volume 2026, Issue 1, 2026.
The purpose of this research was to investigate how adding dietary guar gum to high‐lipid diets affected the fish growth and gut health of common carp (Cyprinus carpio). A normal‐lipid diet (5% crude lipid; control) and four high‐lipid diets (10% crude lipid) with 0% (high‐fat [HF]), 0.3% (GG0.3), 1% (GG1), and 3% (GG3) of guar gum were developed and ...

Chlamydial Lytic Exit from Host Cells Is Plasmid Regulated

open access: yesmBio, 2015
Chlamydia trachomatis is an obligate intracellular bacterium that is a globally important human pathogen. The chlamydial plasmid is an attenuating virulence factor, but the molecular basis for attenuation is not understood.
