S-layers at second glance? Altiarchaeal grappling hooks (hami) resemble archaeal S-layer proteins in structure and sequence

Frontiers in Microbiology, 2015
The uncultivated Ca. Altiarchaeum hamiconexum (formerly known as SM1 Euryarchaeon) carries highly specialized nano-grappling hooks (hami) on its cell surface. Until now little is known about the major protein forming these structured fibrous cell surface

Unveiling a Novel Mechanism of Enhanced Secretion, Cargo Loading, and Accelerated Dynamics of Bacterial Extracellular Vesicles Following Antibiotic Exposure

Journal of Extracellular Vesicles
Antibiotic exposure substantially alters the production mechanisms of bacterial extracellular vesicles (BEVs), which serve as carriers for intercellular exchange of DNA, proteins, and nutrients, yet the underlying mechanisms remain elusive.

Capsular polysaccharide inhibits adhesion of Bifidobacterium longum 105-A to enterocyte-like Caco-2 cells and phagocytosis by macrophages

Gut Pathogens, 2017
Background Bifidobacterium longum 105-A produces markedly high amounts of capsular polysaccharides (CPS) and exopolysaccharides (EPS) that should play distinct roles in bacterial–host interactions. To identify the biological function of B.

Porcine milk fat globule membrane proteins that bind to F4ac fimbria of Escherichia coli

The FASEB Journal, 2012
Post‐weaning colibacillosis in pigs is caused by enterotoxigenic Escherichia coli (ETEC) which is often controlled by antibiotic feed supplements with potential risk of generation of antibiotic resistant bacteria.

Egy virulencia regulátor mutáns Salmonella enterica törzs mint kereszt-immunitást biztosító orális vakcina jelölt vizsgálata = Investigation of a virulence regulator mutant strain of Salmonella enterica as a candidate for live oral vaccine providing cross-immunity

, 2008
Kutatásaink során egy Salmonella rfaH mutánst mint potenciális vakcina jelöltet vizsgáltunk több aspektusból. Mivel az RfaH fehérje egy transzkripciós regulátor, vizsgáltuk, hogy mely virulencia faktorokra kifejtett hatása okozza a vakcina törzs ...

Nucleotide sequence of the genes coding for minor fimbrial subunits of the F1C fimbriae of Escherichia coli [PDF]

, 1991
F 1 C fimbriae allow uropathogenic Escherichia coli to adhere to specific epithelial surfaces. This adhesive property is probably due to the presence of minor fimbrial components in F1C fimbriae. The foe gene cluster encoding F1C fimbriae has been cloned,

Detection of functional P fimbriae proteins in E. coli outer membrane vesicles

Background: Outer membrane vesicles (OMVs) are continuously released from the surface of Gram negative bacteria. The composition of the OMVs is similar to that of the outer membrane and may include periplasmic constituents.
