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 ...

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 ...

Exotic Pets and Zoonotic Spillover Risk: Epidemiology and Antibacterial Resistance, a Rapid Systematic Review

open access: yesInterdisciplinary Perspectives on Infectious Diseases, Volume 2026, Issue 1, 2026.
This rapid review aims to examine the potential zoonotic risks associated with exotic pets. This systematic review explores various aspects of zoonotic diseases and their transmission through exotic pets. We followed the PRISMA methodology, applying four inclusion and exclusion criteria.

Innovative Chitosan‐Based Formulation for Controlled Release of Enrofloxacin: Pharmacokinetic Analysis in Rabbits

open access: yesVeterinary Medicine and Science, Volume 11, Issue 6, November 2025.
This study develops a novel triple‐layer chitosan film for sustained enrofloxacin delivery in rabbits. The implant significantly extends drug residence time (29‐fold) and maintains therapeutic levels for 144 h, offering a promising strategy to reduce dosing frequency in veterinary practice.

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 ...

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

Ultrastructural Insights Into a Candidatus Parilichlamydia sp. Infection of Gill Goblet Cells in Greater Amberjack

open access: yesJournal of Fish Diseases, Volume 48, Issue 11, November 2025.
ABSTRACT Despite recent genomic studies and increased molecular data, epitheliocystis remains an enigmatic fish disease with no experimental in vitro or in vivo models to aid the advancement of research. In this study, we revert to a classical microscopical approach and screen with the electron microscope the epitheliocystis lesions caused by a Ca ...

Developmental Cycle and Genome Analysis of Protochlamydia massiliensis sp. nov. a New Species in the Parachlamydiacae Family

open access: yesFrontiers in Cellular and Infection Microbiology, 2017
Amoeba-associated microorganisms (AAMs) are frequently isolated from water networks. In this paper, we report the isolation and characterization of Protochlamydia massiliensis, an obligate intracellular Gram-negative bacterium belonging to the ...
