Cryo-EM analysis of the organization of BclA and BxpB in the Bacillus anthracis exosporium [PDF]

Journal of Structural Biology, 2014
Bacillus anthracis and other pathogenic Bacillus species form spores that are surrounded by an exosporium, a balloon-like layer that acts as the outer permeability barrier of the spore and contributes to spore survival and virulence. The exosporium consists of a hair-like nap and a paracrystalline basal layer.

An Unusual Mechanism of Isopeptide Bond Formation Attaches the Collagenlike Glycoprotein BclA to the Exosporium of Bacillus anthracis

mBio, 2011
The outermost exosporium layer of spores of Bacillus anthracis, the causative agent of anthrax, is comprised of a basal layer and an external hairlike nap. The nap includes filaments composed of trimers of the collagenlike glycoprotein BclA.

Nucleotide polymorphism assay for the identification of west African group Bacillus anthracis: a lineage lacking anthrose

BMC Microbiology, 2020
Background The exosporium of the anthrax-causing Bacillus anthracis endospores display a tetrasaccharide composed of three rhamnose residues and an unusual sugar termed anthrose.

Understanding host immune responses in Clostridioides difficile infection: Implications for pathogenesis and immunotherapy

iMeta, Volume 3, Issue 3, June 2024.
The progression of Clostridioides difficile infection (CDI) is shaped by multiple factors, such as antibiotic usage, age, comorbidities, immune gene polymorphisms, and antibody levels. Among these, the immune response stands out as a pivotal determinant in controlling both the course and severity of CDI.

Proteome of spores from biological indicators in sterilization processes: Bacillus pumilus and Bacillus atrophaeus

PROTEOMICS, Volume 24, Issue 9, May 2024.
Abstract Bacillus atrophaeus and Bacillus pumilus spores are widely used as biological indicators to assess the effectiveness of decontamination procedures. Spores are intricate, multi‐layered cellular structures primarily composed of proteins, which significantly contribute to their extreme resistance.

Hyperspectral imaging and deep learning for detection and quantification of germination in Bacillus cereus spores

International Journal of Food Science &Technology, Volume 59, Issue 5, Page 3505-3513, May 2024.
Hyperspectral imaging (HSI) and deep learning have the potential for the detection and quantification of germination in Bacillus cereus spores. The spectral data in the visible‐near‐infrared range are sensitive to unique structural and chemical characteristics specific to spores, setting them apart from their vegetative counterparts and non‐biological ...
