Surface layer protein EA1 is not a component of Bacillus anthracis spores but is a persistent contaminant in spore preparations.

EA1 is an abundant, highly antigenic, surface layer protein of Bacillus anthracis vegetative cells. Recent studies indicate that EA1 is also a component of B. anthracis spores and a potential marker for spore detection. We show here that EA1 is not a spore component but a persistent contaminant in spore preparations.

Detection of B. anthracis Spores and Vegetative Cells with the Same Monoclonal Antibodies

Bacillus anthracis, the causative agent of anthrax disease, could be used as a biothreat reagent. It is vital to develop a rapid, convenient method to detect B. anthracis. In the current study, three high affinity and specificity monoclonal antibodies (mAbs, designated 8G3, 10C6 and 12F6) have been obtained using fully washed B. anthracis spores as an immunogen. These mAbs, confirmed to direct ...

Identification and Characterization of Bacillus anthracis Spores by Flow Cytometry

Rapid and accurate detection of Bacillus anthracis, the causative agent of anthrax, remains an active area of research due to the continued threat of bioterrorist attack. The ability to differentiate Bacillus anthracis spores from spores belonging to other Bacillus species is important for the development of spore-based detection methods. Furthermore, not all Bacillus anthracis strains are full...

Roles of the Bacillus anthracis spore protein ExsK in exosporium maturation and germination.

The Bacillus anthracis spore is the causative agent of the disease anthrax. The outermost structure of the B. anthracis spore, the exosporium, is a shell composed of approximately 20 proteins. The function of the exosporium remains poorly understood and is an area of active investigation. In this study, we analyzed the previously identified but uncharacterized exosporium protein ExsK. We found ...

Identification of proteins in the exosporium of Bacillus anthracis.

Spores of Bacillus anthracis, the causative agent of anthrax, possess an exosporium. As the outer surface layer of these mature spores, the exosporium represents the primary contact surface between the spore and environment/host and is a site of spore antigens. The exosporium was isolated from the endospores of the B. anthracis wild-type Ames strain, from a derivative of the Ames strain cured o...
