Role of the gerP Operon in Germination and Outgrowth of Bacillus anthracis Spores
Germination of Bacillus anthracis spores occurs when nutrients such as amino acids or purine nucleosides stimulate specific germinant receptors located in the spore inner membrane. The gerP(ABCDEF) operon has been suggested to play a role in facilitating the interaction between germinants and their receptors in spores of Bacillus subtilis and Bacillus cereus. B. anthracis mutants containing del...
متن کاملRole of germinant receptors in Caco-2 cell-initiated germination of Bacillus cereus ATCC 14579 endospores.
Spores obtained from Bacillus cereus ATCC 14579 and mutant strains lacking each of seven germinant receptor operons were exposed to differentiated Caco-2 cells and monitored for germination. Spores of the gerI and gerL mutants showed a reduced germination response, pointing to a role for these receptors in Caco-2-induced germination.

Keynan, A. (University of Wisconsin, Madison) and H. O. Halvorson. Calcium dipicolinic acid-induced germination of Bacillus cereus spores. J. Bacteriol. 83:100-105. 1962.-The germination of spores of Bacillus cereus strain T can be initiated by calcium dipicolinic acid. The kinetics of germination are characterized by a long lag period followed by a rapid loss of refractility. The lag period di...
متن کاملThe nutritional requirements for germination and outgrowth of spores and vegetative cell growth of some aerobic spore forming bacteria.
During the last 10 years the subject of bacterial spore germination has been intensively investigated. In most of these studies it has been found that bacterial spores are capable of germination under conditions which do not permit the germinated form to survive (Schmidt, 1955; Stedman, 1956). Hills (1949) pointed out that a distinction must be drawn between the requirements for germination and...
متن کاملCriteria for the identification of Bacillus anthracis.
The identification of Bacillus anthracis involves its differentiation from other aerobic sporeformers, particularly Bacillus cereus. Smith et al. (1952), in a study of aerobic sporeforming bacteria, concluded that B. anthracis is a pathogenic variety of B. cereus. They also stated that strains of B. anthracis which had lost their virulence could not be differentiated from B. cereus. This appare...
