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
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. ...191519867897

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 ...193319870138
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 ...193319870181
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 ...193319872719
