the activation effect of calcium on a bactericidal substance for bacillus subtilis in human serum.an enhanced bactericidal activity of human serum for b. subtilis develops during many different forms of illness, e.g. carcinoma, virus and bacterial infections, and during acute coronary occlusion. this increased bactericidal effect cannot be related to leucocytosis, fever, serum complement, c-reactive protein, or a specific antibody reaction. the serum bactericidal factor becomes inactive in decalcified serum, but active again when optimal concentrations of calcium are added. magnesium does no ...195015428579

the presence in normal serum of inhibiting substances against bacillus subtilis.sera from 35 normal persons who had received no previous medication were tested for inhibiting substances against bacillus subtilis and staphylococcus aureus. thirty of the sera (85 per cent) inhibited bacillus subtilis in dilutions varying up to 1:32, but in no instance was staphylococcus aureus inhibited. the data presented would indicate that bacillus subtilis is not a suitable organism for use in the assay of antibiotics in the presence of serum.194617748226

resistance of bacterial spores to the triphenylmethane dyes.1. bacterial spores are highly resistant to the bactericidal action of the triphenylmethane dyes. many bacillus anthracis and bacillus subtilis spores resist a saturated aqueous solution of gentian violet for 24 hours at 37 degrees c. they also resist exposure to the same dye solution for 10 minutes at 80 degrees c. 2. the selective bactericidal action of these dyes applies only to the vegetative cells. spores of the gram-positive bacteria are more resistant to these dyes than the vegetative cel ...192519869002
the source of the microorganisms in the lungs of normal animals.it has been possible to show that the lungs of such animals as the calf, rabbit, guinea pig, white rat, and white mouse are readily invaded by organisms. the most frequent types observed in cultures from the border of the lungs have been streptothrix, molds, and bacteria of the bacillus subtilis group. these forms originate in certain dry food stuffs (hay and straw). by withholding or moistening these materials it has been possible to diminish the number of organisms in the lungs. when these mat ...192219868674
comparative studies on respiration : xiv. antagonistic action of lanthanum as related to respiration.1. concentrations of la(no(3))(3) up to 0.000025 m have little effect upon the rate of respiration of bacillus subtilis; at 0.000006 m there is an increase in rate, while in higher concentrations there is a decrease in rate. 2. there is well marked antagonism between la(no(3))(3) and nacl, and very slight antagonism between la(no(3))(3) and cacl(2). 3. it requires a very small amount of la(no(3))(3) to antagonize nacl, the proportions of the two salts at their maximum antagonism being 99.8 parts ...192119871869
the effect of hydrogen ion concentration on the production of carbon dioxide by bacillus butyricus and bacillus subtilis.1. the maximum rate of co(2) production of bacillus butyricus was found to be at a ph value of 7; of bacillus subtilis at ph 6.8. if the ph value be raised or lowered there is a progressive decrease in the rate of production of co(2). 2. spontaneous recovery follows the addition of alkali to either organism, while addition of acid is followed by recovery only upon addition of an equivalent amount of alkali, and is not complete except when the amount of acid is very small.192119871925
comparative studies on respiration : x. toxic and antagonistic effects of magnesium in relation to the respiration of bacillus subtilis.1. concentrations of mgcl(2) up to 0.01 m have little effect upon the rate or respiration of bacillus subtilis; at 0.03 m there is an increase in the rate, while in the higher concentrations there is a gradual decrease. 2. there is a well marked antagonism between mgcl(2) and nacl, and a very slight antagonism between mgcl(2) and cacl(2).192019871815
influence of temperature and hydrogen ion concentration upon the spore cycle of bacillus subtilis.1. at 5 degrees c. no germination took place. 2. at 25 degrees c. and at 37 degrees c. germination occurs if the hydrogen ion concentration of the broth is kept between ph 5 and ph 10, but not at higher or lower ph values. 3. the completion of the spore cycle likewise requires a hydrogen ion concentration between ph 5 and ph 10. 4. the spores can germinate when the ph value is 10, although after germination the vegetative cells multiply only to a very slight extent and soon pass into spores. 5. ...191919871758
comparative studies on respiration : viii. the respiration of bacillus subtilis in relation to antagonism.1. in relatively low concentrations of nacl, kcl, and cacl(2) the rate of respiration of bacillus subtilis remains fairly constant for a period of several hours, while in the higher concentrations, there is a gradual decrease in the rate. 2. nacl and kcl increase the rate of respiration of bacillus subtilis somewhat at concentrations of 0.15 m and 0.2 m respectively; in sufficiently high concentrations they decrease the rate. cacl(2) increases the rate of respiration of bacillus subtilis at a co ...191919871789
comparative studies on respiration : iii. the effect of ether on the respiration and growth of bacillus subtilis.1. in all the concentrations of ether studied (from 0.037 to 7.3 per cent) there is an increase in the rate of respiration of bacillus subtilis followed by a decrease. 2. in 7.3 per cent ether in tap water there is an extraordinary increase in the output of co(2) (amounting to 50 times the normal). this does not occur when 0.85 per cent nacl is added, which indicates antagonism between ether and nacl. 3. ether is toxic in low concentrations (0.037 to 1.1 per cent) and high concentrations (3.65 t ...191819871736
a study of the antiseptic properties of certain organic compounds.this study of the inhibitive effect of aniline and some of its derivatives and of the triphenylmethane dyes on certain bacteria warrants the following tentative conclusions: 1. the composition and reaction of the medium exert a marked influence on the behavior of the antiseptic. the higher the concentration of organic nitrogenous compounds (peptone) in the medium, the lower is the effective concentration of the dye. the reaction of the medium modifies the specific action of the antiseptic, owing ...191819868219
the effect of gentian violet on protozoa and on tissues growing in vitro, with especial reference to the nucleus.1. gentian violet may be regarded as a true vital nuclear stain. 2. embryonic and adult tissue of the frog will grow in vitro in the presence of gentian violet of a far stronger dilution than that necessary to kill many bacteria. in these experiments, for example, successful tissue growths were obtained when gentian violet 1 to 20,000 was used, yet bacillus subtilis will not grow in 1 to 100,000 dilution and grows very badly in 1 to 1,000,000 dilution. this fact may simplify the technique of the ...191419867841
the cultivation of amoebae in pure culture upon autolyzed tissues.since the purpose of this paper is to record the cultivation of amoebae upon autolyzed tissue without bacterial association, the morphological characteristics, life cycle, means of differentiating species, and pathogenicity of the protozoa have been omitted. these subjects will be considered in later publications. the result of this study proves that some species of amoebae from liver abscesses and the human intestine can be cultivated upon various autolyzed tissues of man and some of the lower ...191319867701
