Abstract: Surface carbohydrate moieties are essential for bacterial communication, phage-bacteria and host-pathogen interaction. Most Staphylococcus aureus produce polyribitolphosphate type Wall teichoic acids (WTAs) substituted with α- and/or β-O-linked N-acetyl-glucosamine (α-/β-O-GlcNAc) residues. GlcNAc modifications have attracted particular… read more here.

DOI: 10.1099/mgen.0.000902
Abstract: Staphylococcus aureus (S. aureus) is a leading cause of skin and soft tissue infections and (hospital-acquired) systemic infections. Wall teichoic acids (WTAs) are cell wall-anchored glycopolymers that are important for S. aureus nasal colonization, endocarditis,… read more here.

DOI: 10.1111/1462-2920.14351
Abstract: Wall teichoic acids (WTAs) are important surface glycopolymers involved in various physiological processes occurring in the Gram-positive cell envelope. We previously showed that the decoration of Listeria monocytogenes (Lm) WTAs with l-rhamnose conferred resistance against… read more here.

DOI: 10.1371/journal.ppat.1007723
Abstract: Staphylococcus aureus and other bacterial pathogens affix wall teichoic acids (WTAs) to their surface. These highly abundant anionic glycopolymers have critical functions in bacterial physiology and their susceptibility to β-lactam antibiotics. The membrane-associated TagA glycosyltransferase… read more here.

DOI: 10.3389/fmicb.2022.897682
Abstract: Free fatty acids (FFAs) have strong antimicrobial properties against pathogenic bacteria and are known as natural protective agents against bacterial infections. Growth of the foodborne pathogen Listeria monocytogenes is highly affected by the presence of… read more here.
