Characterization of Exosporium Layer Variability of Clostridioides difficile Spores in the Epidemically Relevant Strain R20291

Frontiers in Microbiology, 2020
Clostridioides difficile is a Gram-positive anaerobic intestinal pathogenic bacterium and the causative agent of antibiotic-associated diarrhea. C. difficile spore is a dormant state which acts as a vehicle of transmission and infection. In C.

Diverse supramolecular structures formed by self-assembling proteins of the Bacillus subtilis spore coat. [PDF]

Mol Microbiol, 2015
Bacterial spores (endospores), such as those of the pathogens Clostridium difficile and Bacillus anthracis, are uniquely stable cell forms, highly resistant to harsh environmental insults.

Bacillus subtilis Spore Coat [PDF]

Microbiology and Molecular Biology Reviews, 1999
SUMMARY In response to starvation, bacilli and clostridia undergo a specialized program of development that results in the production of a highly resistant dormant cell type known as the spore. A proteinacious shell, called the coat, encases the spore and plays a major role in spore survival.

Coordinated Assembly of the Bacillus anthracis Coat and Exosporium during Bacterial Spore Outer Layer Formation

mBio, 2018
Bacterial spores produced by the Bacillales are composed of concentric shells, each of which contributes to spore function. Spores from all species possess a cortex and coat, but spores from many species possess additional outer layers.

Assessment of chemical methods in the extraction of spore surface layers in Clostridioides difficile spores

mSphere
Clostridioides difficile spores are essential for initiation, recurrence, and transmission of C. difficile infections (CDI). These outermost layers of the spore, the exosporium and spore coat, are responsible for initial interactions with the host and ...

Spore germination and development of young mycelia in some Rhizopogon species [PDF]

, 2000
Spore germination in Rhizopogon abietis, R. luteolus, R. roseolus and R. villosulus was induced in the presence of Rhodotorula glutinis and activated charcoal, in agar medium (N6:5). In one R.

Chaperone protein DnaK-mediated regulation of spore coat assembly in

iScience
Summary: Bacterial spores pose a significant challenge to the food industry due to their ability to germinate from dormancy and their extreme resistance. Spores are encased by a multilayered proteinaceous structure termed the spore coat. Previous studies
