Characterization of the Neurospora crassa Galactosaminogalactan Biosynthetic Pathway

Microorganisms
The Neurospora crassa genome has a gene cluster for the synthesis of galactosaminogalactan (GAG). The gene cluster includes the following: (1) UDP-glucose-4-epimerase to convert UDP-glucose and UDP-N-acetylglucosamine to UDP-galactose and UDP-N ...

Adhesive Functions or Pseudogenization of Type Va Autotransporters in Brucella Species

Frontiers in Cellular and Infection Microbiology, 2021
Adhesion to host cells is a key step for successful infection of many bacterial pathogens and may define tropism to different host tissues. To do so, bacteria display adhesins on their surfaces.

Beyond antimicrobials: Ecological nano‐strategies for rebalancing dysbiotic oral microbial homeostasis

BMEMat, EarlyView.
Oral microbial homeostasis, a dynamic host‐microbe balance, is vital in infectious diseases. Conventional antibiotics often disrupt this homeostasis, spurring interest in nanomaterials for oral microbial homeostasis rebalancing. This review outlines nanomaterial strategies across three ecological levels (population/community, ecosystem, and cross ...

Crystal structure of the P pilus rod subunit PapA [PDF]

, 2007
P pili are important adhesive fibres involved in kidney infection by uropathogenic Escherichia coli strains. P pili are assembled by the conserved chaperone-usher pathway, which involves the PapD chaperone and the PapC usher.

Mycobacterial Adhesion: From Hydrophobic to Receptor-Ligand Interactions

Microorganisms, 2022
Adhesion is crucial for the infective lifestyles of bacterial pathogens. Adhesion to non-living surfaces, other microbial cells, and components of the biofilm extracellular matrix are crucial for biofilm formation and integrity, plus adherence to host ...

Oral Bacterial Extracellular Vesicles as Systemic Messengers: A Mouth–Gut–Systemic Axis Paradigm

Gut Medicine, EarlyView.
ABSTRACT Oral microbiome dysbiosis not only associated with localized periodontal disease but also with multiple systemic diseases, including cardiovascular disease, diabetes mellitus, Alzheimer's disease, rheumatoid arthritis, and cancer. However, the efficiency with which intact viable bacteria cross biological barriers to reach distant organs is ...

High‐Sugar Diet and Intestinal Diseases: A Shared Microbiota–Barrier–Immunity–Metabolism Axis in Inflammatory Bowel Disease, Food Allergy, and Colorectal Cancer

iNew Medicine, EarlyView.
ABSTRACT The global incidence of intestinal diseases—including food allergy, inflammatory bowel disease (IBD), and colorectal cancer (CRC)—continues to escalate in parallel with the expansion of the “Western diet,” within which the high‐sugar diet (HSD) has emerged as a pivotal yet under‐recognized dietary driver.
