the chemical alteration of a bacterial surface, with special reference to the agglutination of b. proteus ox-19. | the chemical substitution of a bacterial surface has been effected by the addition of benzene sulfonyl chloride to b. proteus ox-19. the substitution of imidazole and amino groups on the bacteria has been followed by the microelectrophoretic method. concomitant changes in the agglutinability of substituted organisms have been observed, without appreciable change in the antibody-combining capacities of the organisms. the significance of these observations has been discussed. | 1945 | 19871488 |
i. the relation between attachment to the substratum and ingestion by ameba in strychnine sulfate solution and conditioned media : ii. biological assay of conditioned media. | 1. strychnine sulfate 0.000069 m decreased percentage attachment to the substratum by amoeba proteus in 0.0029 m nacl from 77.3 to 1.3, in 0.0029 m kcl from 40.8 to 2.5, in 0.002 m cacl(2) from 73.3 to 68.0, in 0.002 m mgcl(2) from 85.5 to 83.3. 2. frequency of ingestion of chilomonads by amoeba proteus is increased by adding strychnine sulfate to solutions of nacl, kcl, or cacl(2). frequency of ingestion is increased in nacl solution from 1.3 to 2.3, in kcl from 0.75 to 2.25, and in cacl(2) fro ... | 1944 | 19873390 |
experimental typhus infection in the eastern cotton rat (sigmodon hispidus hispidus). | 1. the course of typhus infection in cotton rats has been described, and a relationship between the dose administered and the time of death has been demonstrated. 2. rather incomplete pathological studies indicated that typhus in the cotton rat is an acute infection primarily involving mesothelial tissue, and tissues of mesothelial origin. depending somewhat upon the route of infection, rickettsiae were most easily demonstrated in smears from liver, brain, and pericardial and peritoneal exudates ... | 1944 | 19871421 |

the antigenic relationship between bacillus proteus x-19 and rickettsiae : iii. a study of the antigenic composition of the extracts of bacillus proteus x-19. | two substances differing in immunological behavior as well as in certain chemical properties have been isolated from soluble extracts of b. proteus x-19. both substances appear to be polysaccharides. the first substance is precipitated from x-19 crude extracts by a relatively low percentage of alcohol and electrolytes (from one to two and a half volumes of alcohol). when purified as far as possible, it gives a negative biuret reaction, a positive molish and has a nitrogen content of 4 per cent. ... | 1935 | 19870415 |
the antigenic relationship between proteus x-19 and typhus rickettsia : ii. a study of the common antigenic factor. | a soluble specific substance was isolated from mexican typhus rickettsia which gave, with proteus x-19 antiserum and typhus human serum, the same precipitation reactions as the polysaccharides extracted from b. proteus ox-19. the soluble specific substance extracted from rickettsia and proteus ox-19 is likely to be of a polysaccharide nature owing to the strong molisch reactions obtained with such extracts, the heat stability and the negative protein reactions (biuret). since, however, it still ... | 1934 | 19870282 |

the antigenic relationship between proteus x-19 and typhus rickettsiae : a study of the weil-felix reaction. | 1. the absorption of typhus sera (human or antityphus horse serum) with proteus x-19 removes only the proteus agglutinins, leaving the rickettsia agglutinins intact. 2. the absorption of typhus sera with mexican rickettsiae removes the agglutinins for both the rickettsia and proteus x-19. 3. while normal or formalinized rickettsiae are not agglutinated by anti-proteus serum, these organisms-when formalinized and heated at 75 degrees c.-become agglutinable by such serum. 4. the absorption of anti ... | 1933 | 19870181 |
studies on typhus fever : xi. a report on the properties of the serum of a horse immunized with killed formalinized rickettsia. | the experiments recorded above demonstrate that the systematic treatment of a horse with formalin- and phenol-killed rickettsiae obtained from the mexican virus by our x-ray rat technique induces the development of properties in the horse's serum which may be described as follows: 1. an original agglutinating potency for proteus x-19 (weil-felix reaction) not exceeding dilutions of 1-40 was enhanced to a potency of 1-160 and, feebly, 1-320. 2. the horse's serum, after immunization, exerts distin ... | 1933 | 19870138 |
on the rate of oxygen consumption by fertilized and unfertilized eggs : v. comparisons and interpretation. | 1. the rate of oxygen consumption by eggs may not merely undergo no change at fertilization, as in the case of the starfish, but it decreases to about half in chaetopterus and in cumingia. 2. the absolute rate of oxygen consumption in mm.(3) o(2) per hour per 10 mm.(3) eggs differs widely in several species of unfertilized eggs. it is very low in the sea urchin, intermediary in nereis, and high in chaetopterus and cumingia. the range for these eggs is approximately 0.4 to 3.1 mm.(3) o(2) per hou ... | 1933 | 19872719 |
carbohydrates adsorbed on colloids as antigens. | evidence is here given that polysaccharides can be rendered antigenic by haptogenic adsorption upon a colloid carrier. the polysaccharides studied were those of b. anthracis, the meningococcus, streptococcus viridans (bargen), b. proteus, s. morgani, b. dysenteriae, both the shiga and hiss types, and the pneumococci. with the polysaccharide of type iii pneumococci, we have been unable in 6 weeks to produce any detectable protective antibodies, but we were able to produce anticarbohydrate antibod ... | 1932 | 19869994 |
studies on typhus fever : ix. on the serum reactions of mexican and european typhus rickettsia. | 1. the blood of guinea pigs convalescent from old world and new world typhus infection develops agglutinating properties for the tunica and rat rickettsiae of the new world diseases and for the louse rickettsia of the old world disease. 2. the two microorganisms are closely related, though probably not identical. 3. human convalescents of both varieties of typhus develop agglutinins for both types of rickettsiae. such rickettsia-agglutinating properties are parallel with the weil-felix reaction ... | 1932 | 19870078 |

on precipitable substances derived from bacillus typhosus and bacillus paratyphosus b. | attempts to confirm certain statements that ether-soluble specific substances can be obtained from b. typhosus have lead to negative results. two serologically active protein substances and another that was non-protein have been separated from b. typhosus. the first two are not resistant to tryptic digestion or to treatment with alkaline hypochlorite solution whereas the third resists both. one of the proteins could be extracted with 75 per cent alcohol. specific precipitable substances reacting ... | 1928 | 19869396 |
intracellular oxidation-reduction studies : i. reduction potentials of amoeba dubia by micro injection of indicators. | twenty-five oxidation-reduction indicators were injected in oxidized or reduced form into amoeba dubia and amoeba proteus under controlled conditions of oxygen access. (1) under anaerobiosis the ameba was able to reduce completely all the reversible oxidation-reduction indicators down to and including indigo disulfonate. (2) under anaerobiosis the ameba was unable to reoxidize six of the most easily oxidizable indicators. (3) under aerobiosis the ameba was able to reduce completely all the indic ... | 1928 | 19872422 |

a study of the pathogenic properties of bacillus proteus. | some strains of bacillus proteus obtained from human lesions are pathogenic for rabbits, rats, and guinea pigs. there is good evidence that these strains are also pathogenic for man. all cultures obtained from sources other than human infections were non-pathogenic for the laboratory animals. a non-pathogenic culture may be made pathogenic by the use of aggressins or by inoculation into the anterior chamber of the eye. proteus cultures lose their virulence rapidly when grown on artificial media. ... | 1915 | 19867897 |
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 ... | 1913 | 19867701 |
