, 2013 According to a highly polymorphic region in the lytA gene, encoding the major autolysin of Streptococcus pneumoniae, two different families of alleles can be differentiated by PCR and restriction digestion. Here, we provide evidence that this polymorphic

Studies on an autolysin produced by clostridium acetobutylicum
, 1981 An extracellular bacteriocin-like substance produced by Clostridium acetobutylicum was detected during studies on an industrial fermentation process. The bacteriocin-like substance was not inducible by either ultraviolet light or mitomycin C, and its ...

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.

Some properties of autolysin of Clostridium saccharoperbutylacetonicum.
Agricultural and Biological Chemistry, 1982 A lytic enzyme activity (N-acetylmuramidase activity) was found in the supernatant fluid of an exponentially growing culture of Clostridium saccharoperbutylacetonicum (ATCC 13564). The same enzyme activity was also found in the autolysate of the cells and the isolated crude cell walls.

Bacterial Extracellular Vesicles in Biomedical Research and Clinical Translation
Microbial Biotechnology, Volume 19, Issue 4, April 2026.Bacterial membrane vesicle biomedical applications. ABSTRACT Bacterial Extracellular Vesicles (bEVs) are lipid (single‐ or double‐bilayer) nanostructures secreted by virtually all bacteria that play fundamental roles in intercellular communication and have emerged as powerful, multifunctional tools in biomedicine. Their intrinsic ability to encapsulate

The Emerging Role of Microbial Extracellular Vesicles in Neuroinflammation and Neurodegeneration
Medicine Bulletin, Volume 2, Issue 2, Page 231-238, March 2026.ABSTRACT Neurodegenerative and neuropsychiatric disorders are increasingly viewed as systemic conditions shaped by interactions among peripheral immunity, microbiota, and the central nervous system. However, the mechanisms linking microbial activity to neuroinflammation and neurodegeneration remain poorly defined.

The Cell Surface, 2018 The bacterial cell wall is in part composed of the peptidoglycan (PG) layer that maintains the cell shape and sustains the basic cellular processes of growth and division. The cell wall of Gram-positive bacteria also carries teichoic acids (TAs). In this

Critical role of a ferritin-like protein in the control of Listeria monocytogenes cell envelope structure and stability under β-lactam pressure. [PDF]
PLoS ONE, 2013 The human pathogen Listeria monocytogenes is susceptible to the β-lactam antibiotics penicillin G and ampicillin, and these are the drugs of choice for the treatment of listerial infections.
