The Exosporium of Clostridium pasteurianum [PDF]

Journal of General Microbiology, 1972
SUMMARY: Autolytically liberated spores of Clostridium pasteurianum possessed an open-ended exosporium, which scanning electron microscopy showed as a flimsy integument draped around the rigid spore body. Critical point drying prevented collapse of the exosporium and a material connexion between spore and exosporium was observed in specimens prepared ...

The Impact of YabG Mutations on Clostridioides difficile Spore Germination and Processing of Spore Substrates. [PDF]

Mol Microbiol
YabG is a sporulation‐specific protease that processes cortex‐destined proteins in Clostridioides difficile. Mutations in the promoter region of C. difficile yabG resulted in either high early stage expression or undetectable levels of expression. YabG cleaves the spore cortex lytic enzyme preproSleC to proSleC, which is incorporated into mature spores,

<i>Clostridium difficile</i> and gut health: Bacteria, the gut microbiome, and diet. [PDF]

IMetaOmics
This review explores the mechanisms underlying Clostridium difficile infection (CDI), focusing on the pathogen's life cycle and its pathogenicity within the host. It further explores the interactions between the gut microbiome, gut metabolites, and CDI. Additionally, the review highlights dietary modulation as a promising strategy to restore gut health,

The Structure of the Exosporium of a Pigmented Clostridium [PDF]

Journal of General Microbiology, 1978
Summary: Exosporia surrounding spores of a pigmented Clostridium showed a hexagonal periodicity when negatively stained and were composed of up to 10 lamellae, each 2.6 nm thick, with a centre-to-centre spacing of 5.2 nm. Optical diffraction spectra revealed that isolated fragments of single lamellae contained hexagonal arrays of subunits with a ...

The Clostridium difficile Exosporium Cysteine (CdeC)-Rich Protein Is Required for Exosporium Morphogenesis and Coat Assembly [PDF]

Journal of Bacteriology, 2013
Clostridium difficile is an important nosocomial pathogen that has become a major cause of antibiotic-associated diarrhea. There is a general consensus that C. difficile spores play an important role in C. difficile pathogenesis, contributing to infection, persistence, and transmission. Evidence has demonstrated that C.

Plasmid-encoded genes influence exosporium assembly and morphology in Bacillus megaterium QM B1551 spores. [PDF]

, 2015
Spores of Bacillus megaterium QM B1551 are encased in a morphologically distinctive exosporium. We demonstrate here that genes encoded on the indigenous pBM500 and pBM600 plasmids are required for exosporium assembly and or stability in spores of this ...

The Regulation of Exosporium-Related Genes in Bacillus thuringiensis [PDF]

Scientific Reports, 2016
AbstractBacillus anthracis, Bacillus cereus and Bacillus thuringiensis (Bt) are spore-forming members of the Bacillus cereus group. Spores of B. cereus group species are encircled by exosporium, which is composed of an external hair-like nap and a paracrystalline basal layer.

Specific Exosporium Reaction of Bacillus megaterium [PDF]

Journal of General Microbiology, 1959
SUMMARY: The sporulation of 51 strains of Bacillus megaterium was examined in shaken cultures in potato extract and in Grelet's denned medium. Some abnormal strains are described in which the spores germinate within the sporangia or very soon after their liberation. The spores of B.
