Antibacterial Activity of a Lytic Enzyme Encoded by Pseudomonas aeruginosa Double Stranded RNA Bacteriophage phiYY

Frontiers in Microbiology, 2018
Multidrug-resistant Pseudomonas aeruginosa is one of the most life-threatening pathogens for global health. In this regard, phage encoded lytic proteins, including endolysins and virion-associated peptidoglycan hydrolases (VAPGH), have been proposed as ...

Why Is MS a More Frequent Complication of EBV Infection in Females?

Immunological Reviews, Volume 339, Issue 1, May 2026.
ABSTRACT Multiple sclerosis (MS) is a T helper (Th) cell‐mediated disease that targets central nervous system (CNS) white matter. This disease affects three times more females than males. For many years, the etiology of MS was not well understood and the exact nature of the autoimmune reaction was speculative.

Phages Mediate Bacterial Self-Recognition

Cell Reports, 2019
Summary: Cells are social, and self-recognition is a conserved aspect of group behavior where cells assist kin and antagonize non-kin. However, the role of phage in self-recognition is unexplored.

Isolation of Extracellular Vesicles From Gram‐Negative Bacteria: A Solid Medium‐Based Method Analysis

Journal of Extracellular Biology, Volume 5, Issue 4, April 2026.
ABSTRACT Extracellular vesicles (EVs) produced by gram‐negative bacteria have gained increased scientific interest over the last years due to a growing understanding of their roles in pathogenesis and biotechnological potential. However, isolating such nanoparticles is technically challenging. Here, we evaluated a rapid and reproducible protocol for EV

Controlled overproduction of proteins by lactic acid bacteria [PDF]

, 1997
Lactic acid bacteria are widely used in industrial food fermentations, contributing to flavour, texture and preservation of the fermented products. Here we describe recent advances in the development of controlled gene expression systems, which allow the
