Journal ArticleDOI
Heat shock protein 60 acts as a receptor for the Listeria adhesion protein in Caco-2 cells.
TL;DR: Scanning immunoelectron microscopy qualitatively demonstrated greater binding capacity of wild-type L. monocytogenes strain (F4244) than a LAP-deficient mutant strain (KB208) to Caco-2 cells, corroborating the identification of Hsp60 as a host cell receptor for LAP.
Journal ArticleDOI
Rapid pathogen detection by lateral-flow immunochromatographic assay with gold nanoparticle-assisted enzyme signal amplification.
TL;DR: It is shown that as low as 100 CFU/mL of Escherichia coli O157:H7 can be detected, indicating that the limit of detection can be increased by about 1000-fold due to the signal amplification approach.
Journal ArticleDOI
LAP, an alcohol acetaldehyde dehydrogenase enzyme in Listeria, promotes bacterial adhesion to enterocyte-like Caco-2 cells only in pathogenic species.

TL;DR: In this article, the LAP homologue, an alcohol acetaldehyde dehydrogenase (lmo1634), interacts with host-cell receptor Hsp60 to promote bacterial adhesion during the intestinal phase of Listeria monocytogenes infection.
Journal ArticleDOI
Lactobacillus delbrueckii ssp. bulgaricus B-30892 can inhibit cytotoxic effects and adhesion of pathogenic Clostridium difficile to Caco-2 cells
TL;DR: This study reveals the very first findings that Lactobacillus delbrueckii ssp.
Journal ArticleDOI
A novel and simple cell-based detection system with a collagen-encapsulated B-lymphocyte cell line as a biosensor for rapid detection of pathogens and toxins.
TL;DR: This paper presents the first example of a cell-based sensing system using collagen-encapsulated mammalian cells for rapid detection of pathogenic bacteria or toxin, and demonstrates a potential for onsite use as a portable detection system.
