| blood sugar studies : i. rapid alterations in the blood sugar level of rabbits as result of intravenous injections of killed bacteria of various types. | a rapid rise in the blood sugar level of rabbits was produced by intravenous injections of killed bacillus proteus, bacillus coli, and bacillus paratyphosus b, which returned to nearly the previous level in a few hours time. a less pronounced rise in blood sugar was produced by killed bacillus paratyphosus a and bacillus enteritidis. | 1925 | 19869033 |
| 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 |

| 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 |
| 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 |
