Identification of the Immunodominant Protein and Other Proteins of theBacillus anthracisExosporium [PDF]

Journal of Bacteriology, 2003
ABSTRACTSpores ofBacillus anthracis, the causative agent of anthrax, are enclosed by a prominent loose-fitting, balloon-like layer called the exosporium. Although the exosporium serves as the source of surface antigens and a primary permeability barrier of the spore, its molecular structure and function are not well characterized.

Immunogens related to the synthetic tetrasaccharide side chain of the Bacillus anthracis exosporium [PDF]

Bioorganic & Medicinal Chemistry, 2007
The known methyl 2-O-acetyl-3,4-di-O-benzyl-1-thio-alpha-L-rhamnopyranoside (3) was converted to the corresponding 5-methoxycarbonylpentyl glycoside 4 which was deacetylated. The product 5 was used as the initial glycosyl acceptor to construct two trirhamnoside glycosyl acceptors having HO-3(III) flanked by either benzoyl or benzyl groups, compounds 10

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the risk assessment of botulism resulting from the consumption of vacuum‐packed or modified atmosphere‐packed foods

Food Risk Assess Europe, Volume 3, Issue 1, January 2025.
Abstract Foodborne botulism is caused by the ingestion of a neurotoxin (BoNT) primarily produced by Clostridium botulinum. This bacterium is classified into six phenotypic Groups, with Groups I and II being associated with human disease. BoNT are divided into seven main types with different antigenic potentials, of which types A, B, E, and F are ...

The Bacillus anthracis Exosporium: What’s the Big “Hairy” Deal?

Microbiology Spectrum, 2015
ABSTRACT In some Bacillus species, including Bacillus subtilis , the coat is the outermost layer of the spore. In others, such as the Bacillus cereus family, there is an additional layer that envelops the coat, called the exosporium. In the case of

Commodity risk assessment of Betula pendula and Betula pubescens plants from the UK

EFSA Journal, Volume 22, Issue 11, November 2024.
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by plants of Betula pendula and B.

Ultrastructure of the Exosporium and Underlying Inclusions in Spores of Bacillus megaterium Strains [PDF]

Journal of Bacteriology, 1972
Spores of selected strains of Bacillus megaterium were prepared by various methods and examined with the electron microscope. An exosporium like that of B. cereus , with a nap and basal layer, was found in spores of a B.

The role of endospore appendages in spore–spore interactions in the pathogenic Bacillus cereus group

Environmental Microbiology, Volume 26, Issue 9, September 2024.
This study demonstrates that the aggregation of endospores is facilitated through endospore appendages, also known as ENAs. It highlights the significance of the ENA tip‐fibrilla, particularly the L‐BclA, which forms the tip fibrillum of the L‐ENA, as the functional part of the fibre.

Non‐prime‐ and prime‐side profiling of Pro‐Pro endopeptidase specificity using synthetic combinatorial peptide libraries and mass spectrometry

The FEBS Journal, Volume 291, Issue 17, Page 3820-3838, September 2024.
The bacterial Pro‐Pro endopeptidases (PPEPs) possess the unique ability to hydrolyze proline‐proline bonds. We profiled the full substrate specificity of PPEPs in detail using a combination of synthetic combinatorial peptides and mass spectrometry. With this method, we determined the specificity of previously characterized PPEPs, PPEP mutants, and ...
