| glomerular lesions of subacute bacterial endocarditis. | 1. in most cases of chronic or subacute bacterial endocarditis due to the endocarditis coccus (streptococcus viridans), there exists a distinctive pathological lesion in some of the glomeruli due to bacterial emboli. 2. the salient features of the pathological picture are first, the involvement of one or more loops of a variable number of glomeruli; secondly, the absence of any visible disease in the uninvolved glomeruli and in the uninvolved portions of affected glomeruli; and thirdly, the asso ... | 1912 | 19867526 |
| experimental focalized myocardial lesions produced with streptococcus mitis. | 1. by the intravenous injection into rabbits of streptococcus mitis, we have produced focalized myocardial lesions which are identical with those caused by the injection of streptococcus rheumaticus, and with those produced by bracht and wächter with streptococcus viridans. 2. the lesions differ from those which we produced by injections of streptococci from the chicago epidemic of sore throat (epidemic streptococcus). 3. the lesions are not identical with aschoff bodies and are easily different ... | 1914 | 19867783 |
| complement fixation tests in chronic infective deforming arthritis and arthritis deformans. | 1. from a comparison of the results with arthritis deformans recorded in tables iii, iv, and vi, and with the control cases recorded in table vii, one is justified in concluding that streptococcus viridans is an infectious agent and excites the production of a complement-fixing substance (fixateur) in the organism in cases of arthritis deformans, and, therefore, streptococcus viridans is the probable causative agent of the disease in many cases of arthritis deformans. probably 40 per cent. and m ... | 1914 | 19867802 |
| concerning a polyvalent antigen for the complement fixation test for streptococcus viridans infection. | 1. streptococcus viridans is of extremely low virulence for white mice and rabbits. 2. the serum of rabbits, after a series of intravenous injections of dead or living streptococcus viridans, is poor in complement fixative substance (fixateur of besredka) for streptococcus viridans. 3. antigens prepared from several strains of streptococcus viridans are relatively poor in fixable substance. 4. the technique of complement fixation tests for infection with streptococcus viridans is so laborious an ... | 1914 | 19867803 |
| the formation of methemoglobin by streptococcus viridans. | cultures of streptococcus viridans when brought into contact with red blood corpuscles have the power of transforming oxyhemoglobin into methemoglobin. the reaction occurs only in the presence of living streptococci when they are able to carry on their metabolic activities. the intensity of the reaction runs roughly parallel with the period of growth and multiplication of the bacteria and gradually diminishes and disappears as growth ceases. there is no apparent relation between the activity of ... | 1916 | 19868043 |
| the localization of streptococcus viridans. | the results of our experiments do not substantiate in full the theory of the power of selective action of streptococcus viridans. a few strains showed a remarkable constancy in location and type of lesion, but these strains were greatly in the minority. the location of the lesions in animals seemed to bear no relation to the origin of the organism or to the lesions produced by it in the patient from which the strain was obtained. streptococcus viridans, regardless of site of origin in the patien ... | 1918 | 19868195 |
| studies on experimental pneumonia : iii. spontaneous pneumonia in monkeys. | spontaneous pneumonia occurred to a considerable extent among stock monkeys at the army medical school. this pneumonia occurred chiefly in the form of an epidemic outbreak shortly after the arrival of a large shipment of monkeys, and was shown to be due in large part to transmission of infection from monkey to monkey, either directly or indirectly. that spread of the epidemic was facilitated by overcrowding was indicated by the fact that in a subsequent shipment of monkeys, which were kept in pa ... | 1920 | 19868412 |
| studies on the pneumococcus : ii. dissolution of pneumococci at varying hydrogen ion concentrations. effect of temperature, previous killing of the organisms, and fresh human serum on the phenomenon. behavior of other organisms. | suspensions of living pneumococci in approximately isotonic standard solutions and in approximately isotonic bouillon with ph varying from about 4.0 to 8.0 after incubation show dissolution of organisms in those solutions having a ph higher than about 5.0. dissolution is most marked at a critical range of about ph 5.0 to 7.0. some dissolution also takes place toward the more alkaline end of the scale. no dissolution occurs at the most acid end of the scale. dissolution in the standard solutions ... | 1922 | 19868639 |
| studies on the pneumococcus : iii. dissolution of pneumococci in pneumonic cellular material at varying hydrogen ion concentrations. resistance of certain other organisms to dissolution. | pneumococci of types i, ii, and iii undergo dissolution when mixed with cellular material from the pneumonic lung at a ph of 6.95 and 5.5, but not at a ph of 4.5. an enzyme derived from the bacteria themselves or from the cellular material may be the cause of the dissolution. streptococcus hoemolyticus and streptococcus viridans do not undergo dissolution under similar experimental conditions. | 1922 | 19868640 |
| the action of sodium salicylate upon the formation of immune bodies. | 1. rabbits treated with sodium salicylate in daily doses of from 0.16 to 0.2 gm. per kilo of body weight and at the same time immunized with intravenous injections of streptococcus viridans, both living and in the form of vaccines, and also with washed sheep red blood cells, showed diminished complement-fixing antibodies, agglutinins, and hemolysins when compared with controls similarly immunized. 2. if the antigens were treated with sodium salicylate in vitro and subsequently injected intraveno ... | 1922 | 19868706 |
| studies on the enzymes of pneumococcus : iv. bacteriolytic enzyme. | 1. pneumococci possess an active intracellular enzyme which causes lysis of heat-killed pneumococci of the same and heterologous types and to a less degree of a closely related organism, streptococcus viridans. 2. the optimum reaction for lysis lies between ph 6 and 8. 3. the bacteriolytic action is proportional to the concentration of the enzyme. 4. heating the enzyme for 30 minutes at 60 degrees c. destroys its activity. 5. the possible relation of the enzyme to autolysis is discussed. | 1923 | 19868783 |
| studies on bacterial nutrition : iv. effect of plant tissue upon growth of pneumococcus and streptococcus. | in previous papers it has been shown that unheated plant tissue, in the form of potato, contains the two factors necessary for the growth of organisms of the hemoglobinophilic group. further studies (5) confirmed these findings and showed that yellow and white turnip, carrot, beet, parsnip, and sweet potato can replace blood in the cultivation of bacillus influenzae. in the present paper it has been shown that vegetable tissues also greatly facilitate and stimulate the growth of other organisms ... | 1923 | 19868784 |
| oxidase reaction of various groups of bacteria. | 1. a simple technique is described for studying the oxidase action of bacteria by means of the oxidation of p-aminoleucomalachite green. 2. it is shown that pneumococci under aerobic conditions produced an oxidase when grown on suitable medium. the sera of any of seven different animal species constitute such a medium, the degree of oxidation by the pneumococcus depending upon the animal from which the serum was taken-rat, guinea pig, rabbit, horse, man, cat, and chicken in order of diminishing ... | 1923 | 19868791 |

| the immunological relationships of streptococcus viridans and certain of its chemical fractions : i. serological reactions obtained with antibacterial sera. | 1. agglutination and precipitation by the specific substance of streptococcus viridans are parallel phenomena. separate specific substances have been extracted from strains which are distinct by ordinary serological tests. preliminary chemical examination indicates that the specific substances may be complex carbohydrates. 2. a close relationship between nucleoproteins from different strains of streptococcus viridans is suggested by the existence of a certain amount of cross-precipitation and a ... | 1925 | 19869060 |
| the immunological relationships of streptococcus viridans and certain of its chemical fractions : ii. serological reactions obtained with antinucleoprotein sera. | 1. the immunological behavior of two cell constituents of nonhemolytic streptococci has been studied, (a) one, the so called nucleoprotein, is relatively non-specific and gives rise to an antibody which shows group reactions with nucleoproteins of related species. (b) the other is non-protein by qualitative chemical tests. preliminary chemical examination has indicated that it may be a carbohydrate. although this substance is highly reactive with the specific antibodies produced by the intact ba ... | 1925 | 19869061 |
| studies concerning the relationship between pneumococci and streptococci. | morgenroth and his collaborators grew pneumococci in a medium containing optochin and derived variant forms of bacteria therefrom which were considered to be streptococci of the viridans group. we have repeated these experiments and have also derived variant forms. these atypical races, however, we have found to be identical with the r form of pneumococci which have been obtained by various other methods. that these r cultures are still pneumococci and do not belong in the streptococcus viridans ... | 1927 | 19869229 |
| a comparative study of smooth and rough pneumococcus colonies. | the characteristic appearances exhibited by the surface colonies of both s and r pneumococci in 24 and 48 hour cultures upon rabbit blood agar have been reviewed. emphasis has been laid upon the behavior and structure of the colonies formed by r pneumococci, their frequent similarity to the colonies formed by certain strains of streptococcus viridans, and their failure to undergo rapid autolysis in the first 48-96 hours, a phenomenon which is highly characteristic of the s pneumococcus colonies. ... | 1927 | 19869372 |

| the conversion of hemolytic streptococci to non-hemolytic forms. | from one strain of hemolytic streptococcus three forms were isolated, which produced three different degrees of hemolysis on the surface of blood agar in the presence of oxygen. the original form was moderately hemolytic; the glossy variant was more hemolytic than the original form; and the third form, obtained by passing the original culture through mice, was non-hemolytic. under anaerobic conditions all three forms were hemolytic. the non-hemolytic passage culture, in the presence of an ample ... | 1928 | 19869500 |
| bacteriology of the blood and joints in rheumatic fever. | 1. during the spring of 1928, 29 patients with acute rheumatic fever were subjected to blood cultures, of whom 9, or 31 per cent, yielded a streptococcus. during the spring of 1929, 31 patients with acute rheumatic fever were studied by blood cultures, of whom 26, or 83.9 per cent, yielded a streptococcus. the higher percentage of positive cultures in the 1929 series appears to have been due to improved cultural methods. 2. of the 35 strains of streptococci recovered from blood cultures, 33 have ... | 1929 | 19869651 |
| streptococci in infectious (atrophic) arthritis and rheumatic fever. | the question of the relationship of streptococci to the etiology of infectious arthritis and of rheumatic fever is of the utmost importance. if a streptococcus or group of streptococci could be shown to be associated see pdf for structure with either disease, some form of specific treatment might be available. the possibility of primary streptococcic infection as the cause of rheumatic fever, and, to a less extent, of acute infectious arthritis would seem to be a reasonable conjecture because of ... | 1930 | 19869811 |
| 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 |
| immunological reactions between dextran polysaccharide and some bacterial antisera. | dextran, the synthetic polysaccharide produced by leuconostoc mesenterioides from saccharose, reacts immunologically with antisera from pneumococci, some of the sahnonella and some of the types of streptococcus viridans (bargen). this immunological relationship is independent of the specific antipolysaccharide antibodies of these sera, suggesting the existence of a distinct antibody produced by an active group of the specific bacterial polysaccharide, which is similar or identical to the active ... | 1932 | 19869995 |
| corneal reactions to bacterium granulosis and other microorganisms. | the conclusions which may be drawn from the results of the experiments here presented are: 1. the cornea of the rabbit is highly sensitive to the action of various injected bacteria. the lesions vary from insignificant, transient changes to severe, destructive panophthalmitis, with fine gradations from the mildest to the violent form of inflammation. moreover, animals that receive the same organisms show like changes. 2. the varying degree of inflammatory reaction is related to the pathogenicity ... | 1932 | 19870032 |
