1. Both focal and diffuse glomerulitis has been produced in rabbits by the injection directly into the left renal artery of suspensions of heat killed hemolytic streptococci. 2. Similar lesions in the glomeruli could not be obtained by the injection of suspensions of bismuth oxychloride into the left renal artery of normal rabbits. 3. The acute glomerulitis occurred in only about one-half of th...

Group A beta-hemolytic streptococci (GABHS) rank first among bacterial factors causing tonsillopharyngitis. These bacteria are especially common in school-age groups. The incidence increases winter and seasonal transitions. In this study, we aim to examine the presence of GABHS throat swab samples people from different age Therefore, identified reproductive frequency culture patients admitted w...

Lancefield Group B Streptococci (GBS) are common causes of infection in adults with diabetes as well as a classical cause of perinatal meningitis. The organism is classically a beta-hemolytic streptococcus. We present an unusual case of human infection by a phenotypically rare manifestation of GBS, in which a chemotherapy port exhibited bacteremia of an organism without hemolysis (so-called gam...

A commercial blood agar slide (Streptocult, Orion Diagnostica) was used for preliminary identification of beta-hemolytic streptococci of groups A, C, and G in throat swab specimens. The sensitivity of the test was 93.6% and the specificity was 94.7%, as judged from 580 specimens. A model is suggested for routine processing of throat swab specimens, involving inoculation and reading of the slide...

A method is described for performing type-specific anti-M precipitin tests on group A hemolytic streptococci in 1 mm. capillary pipettes. These tests require so much less precipitating serum than was formerly used that the method now seems to be practical.

The interaction between staphylococci and Group A beta hemolytic streptococci in mixed lesions was investigated in an experimental impetigo model. A strain of staphylococcus of phage Type 71, which has been shown in vitro to produce a bacteriocin for streptococci and other Gram-positive organisms, eliminates or reduces Group A streptococci in mixed lesions. In contrast, staphylococcal strains o...
