DsbB Is Required for the Pathogenesis Process of Xanthomonas campestris pv. campestris
Molecular Plant-Microbe Interactions, 2008 The DsbA/DsbB oxidation pathway is one of the two pathways that catalyze disulfide bond formation of proteins in the periplasm of gram-negative bacteria.

The Periplasmic Flagellum of Spirochetes
Microbial Physiology, 2004 Although spirochete periplasmic flagella have many features similar to typical bacterial flagella, they are unique in their structure and internal periplasmic location. This location provides advantages for pathogenic spirochetes to enter and to adapt in the appropriate host, and to penetrate through matrices that inhibit the motility of most other ...

Characterisation of a Novel Jumbo Lytic Aeromonas dhakensis Bacteriophage P19 and Its Endolysin
Microbial Biotechnology, Volume 19, Issue 1, January 2026.A jumbo, lytic myovirus phage P19 against multidrug‐resistant (MDR) Aeromonas dhakensis was isolated from river water. P19 demonstrated robust lytic activity, high thermal and pH stability (pH 6–10, up to 60°C), and no genes associated with lysogeny, virulence or antimicrobial resistance. ORF_358 of P19 encodes for T4‐type lysozyme.

Quality control in the bacterial periplasm
Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2004 Studies of the mechanisms that Gram-negative bacteria use to sense and respond to stress have led to a greater understanding of protein folding in both cytoplasmic and extracytoplasmic locations. In response to stressful conditions, bacteria induce a variety of stress response systems, examples of which are the sigma(E) and Cpx systems in Escherichia ...

Cyanobacterial Extracellular Vesicles as Protein Carriers: Towards Fish Vaccination
Microbial Biotechnology, Volume 19, Issue 1, January 2026.Here, we describe that Synechocystis EVs are stable nanostructures that can induce specific immune responses in fish with additional adjuvant features. It represents a biotechnological breakthrough towards a novel antigen‐carrier platform for sustainable fish‐pathogen control in aquaculture settings. ABSTRACT Fish aquaculture faces significant economic

Fe biomineralization mirrors individual metabolic activity in a nitrate-dependent Fe(II)-oxidizer
Frontiers in Microbiology, 2015 Microbial biomineralization sometimes leads to periplasmic encrustation, which is predicted to enhance microorganism preservation in the fossil record.

EFSA Journal, Volume 24, Issue 1, January 2026.Abstract The qualified presumption of safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of relevant knowledge and safety concerns of microorganisms intentionally added to the food and feed chain.

Outer membrane phospholipase A’s roles in Helicobacter pylori acid adaptation
Gut Pathogens, 2017 Background The pH of the human gastric mucosa varies around 2.5 so that only bacteria with strong acidic stress tolerance can colonize it. The ulcer causing Helicobacter pylori thrives in the gastric mucosa. We analyse the roles of the key outer membrane
