The immunological phenomena associated with various aspects of hemolytic streptococcus disease in man have usually been studied by the measurement of antitoxins. Most extensive have been the observations made by the Dick technique (1), in which purified erythrogenic toxin was used as a skin test material. Circulating antistreptolysin and antifibrinolysin titers have also been determined, partic...

OBJECTIVES To investigate antibiotic sensitivities of Streptococcus pneumoniae, viridans streptococci, and group A hemolytic streptococci isolated from the culture materials obtained from the sinuses of patients undergoing functional endoscopic sinus surgery due to chronic sinusitis. PATIENTS AND METHODS We recruited 93 patients (63 males, 30 females; mean age 36+/-17.5; range 19 to 68 years)...

Although there is common agreement and occasionfal mention of the fact that nephritis once healed does not recur, there has been little evidence presented in the literature to substantiate this impression. Longcope (1) reports 4 cases out of a series of 24 with healed acute nephritis in whom beta hemolytic streptococci were found subsequently. Two of these, in a single throat culture each, reve...

Troisier and Monaldi (Rg. Med., 1932, 96), having changed Lowenstein's method, performed blood cultures of patients who had one or another infectious disease. A.a. describe 3 cases, from the which VC were cultivated: 1st patient with endocarditis (blood culture produced non-hemolytic streptococcus) died septic cerebral infarction, autopsy did not reveal a single tbc focus. Nth. Croupous pneumon...

A culture of hemolytic streptococcus developed a non-hemolytic fraction which as determined by its agglutinogenic, agglutination, and agglutinin absorotion characters was identical with the hemolytic fraction, the only variation being one of function, or physiological action. This functional variation has proved permanent, as long as observed, for both fractions have continued to breed true. Th...

1. The relation between hemolytic and non-hemolytic streptococci is orderly and arises from the fact that the former variety is unique while the latter is heterogeneous. 2. Analogous considerations of the classification, distribution, and pathogenicity of the streptococcus group and the pneumococcus and colon-typhoid groups show a definite parallelism. 3. These considerations suggest that uniqu...

It was demonstrated by Keogh et al. (1947) and Warburton et al. (1949) that several products of bacterial cultures could be adsorbed to erythrocytes, which then could be agglutinated by sera containing antibodies to those bacterial antigens. This approach was developed in the case of a constituent of tuberculin by Middlebrook and Dubos (1948) and Rothbard et al. (1950). The work of the latter g...

BACKGROUND Here we report a rare case of lumbar spine epidural abscess and facet joint septic arthritis caused by Streptococcus agalactiae, which had spread to the iliopsoas muscles, leading to urine retention. CASE PRESENTATION A 68-year-old woman with low back pain experienced a sudden onset of bilateral lower limb weakness, it was followed 14 days later by urine retention. At consultation,...
