Lactobacillus acidophilus Autolysins Inhibit Helicobacter pylori In Vitro
Current Microbiology, 2001 Antibacterial activity of 17 strains of lactobacilli was tested against 10 strains of H. pylori. The inhibition observed was related to the acid production and the low pH attained. No relationship between CagA phenotype of H. pylori strains and tolerance to lactic acid was observed. In mixed cultures, L. acidophilus CRL 639 showed an autolytic behavior

Mechanisms governing bacterial capsular polysaccharide attachment and chain length
Annals of the New York Academy of Sciences, Volume 1548, Issue 1, Page 80-98, June 2025.Abstract Capsular polysaccharides (CPSs) are high‐molecular weight glycopolymers that form a capsule layer on the surface of many bacterial species. This layer serves as a crucial barrier between bacteria and their environment, protecting them from host immune responses and environmental stressors while facilitating adaptation to host niches.

Dynamic capsule restructuring by the main pneumococcal autolysin LytA in response to the epithelium
Nature Communications, 2016 Pneumococci produce a carbohydrate capsule that protects them against components of the host immune system but sensitizes them to host antimicrobial peptides.

Structural basis of cell wall cleavage by a staphylococcal autolysin. [PDF]
PLoS Pathogens, 2010 The major autolysins (Atl) of Staphylococcus epidermidis and S. aureus play an important role in cell separation, and their mutants are also attenuated in virulence.

Inflammatory mediator response to Gram-positive and Gram-negative bacteria in vitro and in middle ear infections [PDF]
, 2010 Based on the structure of the cell wall, bacteria are divided into Gram-positive and Gram-negative. While the cell wall of Gram-positive bacteria is thick, the cell wall of Gram-negatives is very thin and surrounded by an outer membrane with LPS ...

FEBS Letters, Volume 599, Issue 9, Page 1203-1221, May 2025.The NlpC_P60 superfamily of peptidases is recognised by its key role in bacterial cell wall homeostasis. Recently, studies have also described the involvement of NlpC_P60‐like enzymes in bacterial competitive mechanisms and pathogenesis across several lineages.

Surface adhesins and exopolymers of selected foodborne pathogens [PDF]
, 2014 The ability of bacteria to bind different compounds and to adhere to biotic and abiotic surfaces provides them with a range of advantages, such as colonization of various tissues, internalisation, avoidance of an immune response and survival and ...

Unwrapping the Ciliary Coat: High‐Resolution Structure and Function of the Ciliary Glycocalyx
Advanced Science, Volume 12, Issue 16, April 24, 2025.The ciliary membrane is decorated in glycosylated proteins that define the interaction of the cilium with its environment. The main component of the ciliary coat of the green alga Chlamydomonas reinhardtii, FMG1, is characterized by cryo‐electron microscopy, proteomics, and live cell microscopy with flow‐based adhesion assays.
