Insights into the autotransport process of a trimeric autotransporter, Yersinia Adhesin A (YadA).

Mol Microbiol 2019 Jan 1. Epub 2019 Jan 1.

Department of Biosciences, University of Oslo, Blindernveien 31, 0371, Oslo, Norway.

Trimeric autotransporter adhesins (TAAs) are a subset of a larger protein family called the type V secretion systems. They are localized on the cell surface of Gram-negative bacteria, function as mediators of attachment to inorganic surfaces and host cells, and thus include important virulence factors. Yersinia adhesin A (YadA) from Yersinia enterocolitica is a prototypical TAA that is used extensively to study the structure and function of the type Vc secretion system. Read More

Visualization of translocons in Yersinia type III protein secretion machines during host cell infection.

PLoS Pathog 2018 12 26;14(12):e1007527. Epub 2018 Dec 26.

Institute of Medical Microbiology, Virology and Hygiene, University Medical Center Hamburg-Eppendorf (UKE), Hamburg, Germany.

Type III secretion systems (T3SSs) are essential virulence factors of numerous bacterial pathogens. Upon host cell contact the T3SS machinery-also named injectisome-assembles a pore complex/translocon within host cell membranes that serves as an entry gate for the bacterial effectors. Whether and how translocons are physically connected to injectisome needles, whether their phenotype is related to the level of effector translocation and which target cell factors trigger their formation have remained unclear.

Targeting peptide-enhanced antibody and CD11c dendritic cells to inclusion bodies expressing protective antigen against ETEC in mice.

FASEB J 2019 Feb 15;33(2):2836-2847. Epub 2018 Oct 15.

Key Laboratory of Combining Farming and Animal Husbandry, Ministry of Agriculture, Animal Husbandry Research Institute, Heilongjiang Academy of Agricultural Sciences, Harbin, China.

Enterotoxigenic Escherichia coli (ETEC) remains a massive burden in developing countries with increasing morbidity and mortality rates; it is also an important pathogen in the farming industry and is a leading cause of bacterial diarrhea. Our previous study showed that nanometer-sized inclusion bodies (IBs) of the fimbrial adhesin subunit protein (FaeG), mutation heat-stable enterotoxin a (mSTa), heat-labile enterotoxin b (LTb), and STb (nontargeting) fusion protein as an oral vaccine induced both systemic and mucosal immune responses. In this study, to enhance the protective efficacy to ETEC, we used Yersinia enterocolitica adhesive and M-cell-targeting peptides to analyze high-efficiency antigen-specific immune presentation in the gut.

M cell-targeting strategy enhances systemic and mucosal immune responses induced by oral administration of nuclease-producing L. lactis.

Appl Microbiol Biotechnol 2018 Dec 11;102(24):10703-10711. Epub 2018 Oct 11.

Department of Microbiology and Immunology, Gifu Pharmaceutical University, 1-25-4 Daigaku Nishi, Gifu, 501-1196, Japan.

Efficient delivery of antigens to the gut-associated lymphoid tissue (GALT) is the most critical step for the induction of mucosal immunity by oral vaccines. As M cells are the main portal for luminal antigens into the GALT, the M cell-targeting of antigens affords a promising strategy toward the development of effective oral vaccines. Lactococcus lactis is a fascinating recombinant host for oral vaccines, as they survive and produce antigens in the gut and have a particularly safe profile for human use. Read More

OmpR-Mediated Transcriptional Regulation and Function of Two Heme Receptor Proteins of Bio-Serotype 2/O:9.

Front Cell Infect Microbiol 2018 20;8:333. Epub 2018 Sep 20.

Department of Applied Microbiology, Institute of Microbiology, Faculty of Biology, University of Warsaw, Warsaw, Poland.

We show that strain Ye9 (bio-serotype 2/O:9) utilizes heme-containing molecules as an iron source. The Ye9 genome contains two multigenic clusters, -1 and -2, encoding putative heme receptors HemR1 and HemR2, that share 62% amino acid identity. Expression of these proteins in an mutant defective in heme biosynthesis allowed this strain to use hemin and hemoglobin as a source of porphyrin. Read More

Novel diagnostic ELISA test for discrimination between infections with Yersinia enterocolitica and Yersinia pseudotuberculosis.

Eur J Clin Microbiol Infect Dis 2018 Dec 20;37(12):2301-2306. Epub 2018 Sep 20.

Omnio AB, Umeå, Sweden.

Yersiniosis is a foodborne infection caused by Yersinia enterocolitica or Yersinia pseudotuberculosis. Although yersiniosis is most often self-limiting, some patients develop chronic infections, such as reactive arthritis, glomerulonephritis, or myocarditis, which require an antibiotic treatment. Whereas early infections can be diagnosed by direct detection of bacteria, chronic infections can only be identified by serological tests. Read More
