Studies on the Pathogenicity of Group a Streptococci
A QUANTITATIVE STUDY OF THE COMBINED ANTIPHAGOCYTIC EFFECTS OF THE M PROTEIN AND THE HYALURONIC ACID CAPSULES OF FOUR STRAINS OF GROUP A STREPTOCOCCI REVEALED THE FOLLOWING FACTS RELATING TO THEIR INTRAPERITONEAL VIRULENCE IN MICE AND RATS: 1. The most virulent strain, S23M (matt), produced both a large hyaluronic acid capsule and a full complement of M protein, the combined effects of which re...
متن کاملStudies on the Antigenic Composition of Group a Hemolytic Streptococci
1. In this study a series of experiments showing the antigenic relationship of type 10 and type 12 group A hemolytic streptococci is reported. Agglutinin, precipitin, and passive protection tests with unabsorbed and reciprocally absorbed antisera were employed to show that representative type 10 and 12 strains contain serologically identical M antigens but unrelated type-specific T antigens. 2....

در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...
15 صفحه اولStudies on a toxic cellular component of group A streptococci.
The hemolytic properties of extracts of sonic disrupted group A streptococcal cells have been described previously by Schwab (1956a, 1956b). After a single intradermal injection into rabbits, similar cellular extracts have been observed to induce chronic remittent nodular skin lesions associated with marked changes in the dermal connective tissue. It is the purpose of this communication to desc...
متن کاملStudies on a Lipoproteinase of Group a Streptococci
The opalescence produced in serum by group A streptococci has been investigated. The development of opalescence is shown to be initiated by an enzyme attached to the bacterial cell which acts upon the alpha(1)-lipoprotein fraction of serum liberating the lipids from the protein. This enzyme has been termed a lipoproteinase. Evidence is presented which suggests that the degree of opalescence whi...
