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.194519871488
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 ...194419871421
demonstration of agglutinins for bartonella bacilliformis.1. methods of preparing a satisfactory antigen having been developed, a technique for performing an agglutination test with b. bacilliformis is made available. 2. as a result of repeated intravenous injection of living cultures of b. bacilliformis at short intervals, rabbits have been found to produce a high titre of specific agglutinins which, under the conditions obtaining in the present series of experiments, begins to decline after about one month following the last inoculation. 3. sera from ...194219871168
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. ...193519870415
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 ...193419870282
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
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
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 ...193219870078

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 ...192819869396
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.192519869033
experimental studies on the etiology of typhus fever : i. concurrent infections during the course of experimental typhus fever in guinea pigs.the work reported in this paper relates to the bacteria which can be cultivated from the blood and spleen of guinea pigs at different stages of infection with the virus of typhus fever. the studies show that during the period of incubation and before the onset of fever no ordinary bacteria appear in the cultures, while on the 1st day of the febrile reaction different bacteria were found in 6 of 26 guinea pigs cultured; on the 2nd day, in 10 of 16; on the 3rd day, in 3 of 4; and on the 4th day in ...192119868575
studies on bacterial nutrition : i. growth of bacillus influenzae in hemoglobin-free media.from the data presented in the foregoing experiments it is evident that bacillus influenzae will grow in a fluid medium consisting of plain broth to which have been added small amounts of emulsions or extracts of mucoid bacilli or of bacillus proteus. the bacterial extracts may be made by simple boiling of the bacillary emulsions in broth or saline solution and centrifuging out the bacterial bodies; they may be filtered without losing their growth-inducing property. cultures of bacillus influenz ...192119868534
chilomastix mesnili and a method for its culture.1. cases of flagellate infection of man by chilomastix mesnili have been reported from nearly every locality in the world. they are fairly abundant in the united states and are often confused with cases of infection by trichomonas intestinalis. 2. the shape of chilomastix is pyriform. the body contains the following structures: nucleus, centrosome, primary, secondary, and tertiary blepharoplasts, parabasal, parastyle, peristomal fiber, ventral cytostome, cytostomal flagellum, three anterior flag ...192119868485
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
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
the rate of release of leukocyte pyrogen from rabbit blood incubated with endotoxin.the time course of leukocyte pyrogen liberation from whole rabbit blood incubated at 37 degrees c with various concentrations of proteus endotoxin was studied. the kinetics of the process provide further evidence for the view that leukocyte pyrogen is an independent entity. it was shown that complete liberation of all available leukocyte pyrogen from blood is too slow a process to account for the fevers seen when rabbits are injected with endotoxin. however, very small quantities of leukocyte py ...196719867298
proteins in nucleocytoplasmic interactions : ii. turnover and changes in nuclear protein distribution with time and growth.in previous studies, we showed that essentially all the proteins of the amoeba proteus nucleus could be classified either as rapidly migrating proteins (rmp), which shuttle between nucleus and cytoplasm continuously at a relatively rapid rate during interphase, or as slow turnover proteins (stp), which seem to move hardly at all during interphase. in this paper, we report on the kinetics and direction of the movement of both classes of protein, as well as on aspects of their localization, with a ...196819866726
