Atomic force microscopy of Bacillus spore surface morphology.
Bacillus spore surface morphology was imaged with atomic force microscopy (AFM) to determine if characteristic surface features could be used to distinguish between four closely related species; Bacillus anthracis Sterne strain, Bacillus thuringiensis var. kurstaki, Bacillus cereus strain 569, and Bacillus globigii var. niger. AFM surface height images showed an irregular topography across the ...
متن کاملClostridium difficile Spore-Macrophage Interactions: Spore Survival
BACKGROUND Clostridium difficile is the main cause of nosocomial infections including antibiotic associated diarrhea, pseudomembranous colitis and toxic megacolon. During the course of Clostridium difficile infections (CDI), C. difficile undergoes sporulation and releases spores to the colonic environment. The elevated relapse rates of CDI suggest that C. difficile spores has a mechanism(s) to ...
متن کاملThe timing of cotE expression affects Bacillus subtilis spore coat morphology but not lysozyme resistance.
The synthesis of structural components and morphogenetic factors required for the assembly of the Bacillus subtilis spore coat is governed by a mother cell-specific transcriptional cascade. The first two temporal classes of gene expression, which involve RNA polymerase sigma sigma(E) factor and the ancillary regulators GerR and SpoIIID, are deployed prior to engulfment of the prespore by the mo...
متن کاملEvaluation of Bacillus Spore Survival and Surface Morphology Following Chlorine and Ultraviolet Disinfection in Water
The objective of this paper is to evaluate the change in Bacillus subtilis spore survival and dimensions following ultraviolet and chlorine disinfection in water. Disinfection was monitored by using tools such as atomic force microscopy AFM , particle sizing by the electrozone sensing technique and fluorescence of spores after staining with an optical brightener. Results indicated that there wa...
متن کاملMorphology of the spore of some strains of Clostridium botulinum type E.
Hodgkiss, W. (Torry Research Station, Aberdeen, Scotland), and Z. John Ordal. Morphology of the spore of some strains of Clostridium botulinum type E. J. Bacteriol. 91:2031-2036. 1966.-The spores of four strains of C. botulinum type E show an unusual and elaborate morphology. Numerous tubular appendages radiate from the surface of the spore. The spore and its appendages are enclosed in a delica...
