1. Rabbits were rendered very hypersensitive by relatively small doses of green streptococci given intracutaneously, and somewhat less hypersensitive by similar doses of heat-killed vaccine prepared from hemolytic streptococci. 2. Animals receiving the same doses intravenously gave, upon subsequent testing, lesions slightly more marked than normal controls; but these lesions were qualitatively ...

The purpose of the work was to study microbiome periodontal pockets in workers industries with harmful factors, who have generalized periodontitis. Materials and methods. 91 employees three industrial productions Ivano-Frankivsk region took part study: chemical production, glass agro-industrial complex. Material for microbiological research collected from patients during examinations before sta...

OBJECTIVES To identify the common bacteria in recent peritonsillar abscesses and the prevalence of antibiotic resistance and compare both between adults and children. METHODS This is a retrospective chart review at a single academic institution of patients who underwent either incision and drainage or tonsillectomy for a peritonsillar abscess between 2002 and 2012 (n=69). Medical records were...

The lysis of group A hemolytic streptococci by extracellular enzymes of Streptomyces albus has been studied. The most favorable material for fractionation of the lytic enzymes was obtained by surface growth on shallow layers of liquid medium containing an acid hydrolysate of casein, glucose, and salts. The results of fractionation experiments show that the potent proetolytic enzyme of Streptomy...

Edicine is a therapeutic agent in the management of thromboembolic blockade. Streptokinase presently utilized clinical mase and an extracellular protein secreted by certain strains beta-hemolytic streptococci. It activates plasminogen to produce plasmin, enzyme that breaks down fibrin clots through specific lysine binding sites.

We evaluated 2401 patients with suspected streptococcal pharyngitis with the Culturette 10-minute Group A Strep ID test during a 6-month period in order to determine its suitability for rapid diagnosis in a busy private office practice. Duplicate throat swabs were obtained for each child, and latex agglutination was performed within 15 minutes. In children with negative latex agglutination resu...

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...

Restriction enzyme profiles of group G beta-hemolytic streptococci associated with a point source outbreak and an outbreak of sporadic pharyngitis in two different communities were compared. To asses the epidemiologic utility of this approach for studying group G streptococci, DNA fingerprints of strains responsible for a point source outbreak of pharyngitis associated with the consumption of c...
