location of calcium within bacillus spores by electron probe x-ray microanalysis. | spectroscopic microanalysis of the element-characteristic x rays produced by a scanning electron microprobe was employed to detect calcium and carbon in both intact and thin-sectioned spores of bacillus cereus t and b. megaterium qm b1551. linear scan profiles and multilinear scan images of the x-ray emissions for calcium (ca(kalpha)) were compared with those for carbon (c(kalpha)) as an index of mass. location was accomplished by stereological comparisons with secondary electron images and conv ... | 1972 | 4627927 |
bacillus cereus-induced fluid accumulation in rabbit ileal loops. | the usefulness of the ligated rabbit ileal loop as an experimental model of bacillus cereus food poisoning was investigated. positive responses, as measured by fluid accumulation in the loop, were obtained from 19 of 22 strains of b. cereus. four of six strains of b. thuringiensis also elicited fluid accumulation, but eight strains of other bacillus spp. failed to evoke a response. the growth medium employed markedly affected the ability of a given strain of b. cereus to provoke a response. brai ... | 1972 | 4627964 |
effect of ultrasonic waves on the heat resistance of bacillus cereus and bacillus licheniformis spores. | heat resistance of bacillus cereus and bacillus licheniformis spores in quarter-strength ringer solution decreases markedly after ultrasonic treatments which are unable to kill a significant proportion of the spore population. this effect does not seem to be caused by a loss of ca(2+) or dipicolinic acid. the use of ultrasonics to eliminate vegetative cells or to break aggregates in bacillus spore suspensions to be used subsequently in heat resistance experiments appears to be unadvisable. | 1972 | 4627969 |

photoprotection by dipicolinate against inactivation of bacterial spores with ultraviolet light. | the resistance of three types of bacillus cereus t spores to ultraviolet radiation corresponded to their dipicolinic acid (dpa) content. photoprotection against ultraviolet light was observed in dpa-containing spores and in dpa-less spores irradiated through calcium dipicolinate. | 1973 | 4632312 |
occurrence of glucosamine residues with free amino groups in cell wall peptidoglycan from bacilli as a factor responsible for resistance to lysozyme. | analysis by dinitrophenylation techniques revealed the occurrence of significant amounts of glucosamine residues with free amino groups in the peptidoglycan component of cell walls isolated from bacillus cereus, bacillus subtilis, and bacillus megaterium. a close correlation was demonstrated between the content of n-unacetylated glucosamine residues in the peptidoglycan component and the resistance of the cell walls to lysozyme. these lysozyme-resistant cell walls and peptidoglycan were converte ... | 1973 | 4632317 |
role of glutathione in the morphogenesis of the bacterial spore coat. | there is a marked increase in the half-cystine content of bacterial spores, especially the coat layers at the time of formation of the outer coat. when a cysteine auxotroph of bacillus cereus t is grown on limiting cysteine, the spores contain the normal content of half-cystine, suggesting an alternate source. glutathione appears to be such a supply of cysteine since it is hydrolyzed during sporulation and there are increased activities of the hydrolyzing enzymes at the same time. in addition, a ... | 1973 | 4632393 |
use of fluorouracil-uracil combinations to study growth accompanied by insufficient deoxyribonucleic acid synthesis in bacillus cereus. | 5-fluorouracil (fu) at a concentration of 16 mum almost totally inhibited deoxyribonucleic acid (dna) synthesis and cell division by bacillus cereus, whereas growth continued at an exponential rate (25% of control for at least 3 h). in cultures simultaneously given 160 mum uracil (u) along with the fu, dna synthesis still stopped, but cell division continued for one generation at the control rate and at a much slower rate beyond that; in the meantime, cell mass continued to increase at an essent ... | 1973 | 4632399 |

ultrastructural study of poly- -hydroxybutyrate granules from bacillus cereus. | the freeze-etching technique was used to examine the effects of fracturing and etching on the appearance of poly-beta-hydroxybutyrate granules from bacillus cereus. these granules were examined in extracts isolated by hypochlorite or by sonic treatment, and also in fixed and unfixed intact cells; in the latter case they were compared with granules in thin sections of intact cells. after freeze-fracturing, the diameter of the granules in intact cells was between 240 and 720 nm. the granules consi ... | 1973 | 4123236 |
electron transport system associated with membranes of bacillus cereus during vegetative growth and sporulation. | membranes isolated from bacillus cereus atcc 4342 during vegetative growth and during sporulation contained cytochromes b, c and a + a(3) as well as flavoprotein as determined from reduced-minus-oxidized difference spectra. although there appeared to be no qualitative change in the cytochromes, there was a significant increase in the amount of cytochromes associated with membranes isolated from sporulating cells. succinate and nicotinamide adenine dinucleotide (reduced form) (nadh) reduced the s ... | 1973 | 4125246 |
production of bacteriophage by temperature-sensitive sporulation mutants of bacillus cereus t. | five temperature-sensitive sporulation mutants of bacillus cereus t have been isolated. these mutants are blocked at stage 0 of sporulation at the restrictive temperature (37 c) but are able to sporulate at nearly normal frequencies at the permissive temperature (26 c). a bacteriophage that forms a stable lysogen in the parent strain is induced at increased frequencies in the mutants. this induction is accompanied, in some of the mutants, by a reduction in immunity to the phage. revertants, sele ... | 1973 | 4126824 |
