The Hna Phage Defence Protein: A DNA‐Stimulated Helicase With Cryptic Nuclease Activity

Molecular Microbiology, EarlyView.
The Hna (Helicase‐nuclease Abi) phage defence system consists of a single protein and provides defence through abortive infection. We show that Hna's abortive infection response can be recreated in a heterologous host upon expression of phage single‐stranded DNA binding protein (SSB) and present a characterization of Hna's biochemical activity.

Microbiome‐Dependent Modulation of Trichomonas vaginalis Cytotoxicity and Remodeling of the Parasite Secretome

Molecular Microbiology, EarlyView.
Our study shows that vaginal bacteria can either suppress or amplify the pathogenic behavior of the protozoan parasite Trichomonas vaginalis. A protective Lactobacillus‐dominated microbiome in eubiosis reduces parasite‐induced damage, whereas dysbiotic bacteria enhance cytotoxicity, followed by changes in the profile of the parasite's secreted proteins.

Spectroscopic analysis of bacterial photoreactivation

Photochemistry and Photobiology, Volume 101, Issue 2, Page 494-504, March/April 2025.
This study investigates the effectiveness of fluorescence and Raman spectroscopy in detecting bacterial photoreactivation. Fluorescence spectroscopy shows limitations, because the intense fluorescence of tryptophan and tyrosine masks fluorescence emitted by thymine molecules.

Reconstruction of deep and perforating corneal defects in dogs—A review (Part I/III): Autogenous ocular tissues, donor tissues, and corneal clarity scoring

Veterinary Ophthalmology, Volume 28, Issue 2, Page 519-531, March 2025.
Abstract Corneal reconstruction is a key part of veterinary ophthalmic practice and numerous reconstructive techniques have been described for use in small animals in the peer‐reviewed veterinary literature written in English. Despite the evidence accrued over the last six decades in over 40 clinical articles and numerous other publications on ocular ...

Efficacy of 0.2% povidone‐iodine and 0.1% polyhexamethylene biguanide as preoperative antiseptics in equine ophthalmic procedures

Veterinary Ophthalmology, Volume 28, Issue 2, Page 438-447, March 2025.
Abstract Objective This retrospective study evaluates the efficacy of povidone‐iodine (PI) and polyhexamethylene biguanide (PHMB) as preoperative antiseptics in equine ophthalmic procedures. Animals Studied Horses that underwent routine ophthalmic surgery and procedures.

Lipopolysaccharide‐Specific Aptasensor: A Spectroscopic Approach for Identifying Gram‐Negative Bacteria

Analytical Science Advances, Volume 7, Issue 2, December 2026.
We developed a novel aptasensor by integrating an anti‐lipopolysaccharide aptamer with a G‐quadruplex DNAzyme for the detection of Gram‐negative bacteria. This label‐free, spectroscopy‐based sensor detects E. coli with a limit of ∼2.7 × 105 cells/mL, providing a rapid, cost‐effective and specific method for identifying LPS‐containing bacteria ...
