Streptococci from Throat Cultures
A test employing three fluorogenic 4-methylumbelliferyl substrates and the lectin of Dolichos biflorus was developed for the identification of beta-hemolytic streptococcal colonies associated with throat cultures. This non-serological method is unique in that it permits the accurate identification of groups C, F, and G streptococci, as well as groups A and B streptococci. The method is rapid, s...
متن کاملOptimal site of throat swab for the isolation of beta-hemolytic streptococci.
The optimal site for the isolation of beta-hemolytic streptococci (BHS) from throat cultures was investigated in 164 healthy elementary school children. All throat cultures were streaked onto duplicate blood agar plates (BAP), one of which was taken from the tonsillar fossae and the other from the posterior pharynx. BHS were isolated in cultures from 56 (34.2%) of the children. BHS were more fr...
متن کاملStreptococcus salivarius and Other Non-hemolytic Streptococci of the Human Throat.
The non-hemolytic streptococci of the human throat form, simultaneously, one of the oldest and least known groups of the genus. These familiar but illdefined organisms are usually referred to as the "salivarius group," as "Streptococcus viridars" and "indifferent streptococci" according to the degree of greening produced in blood agar, or simply as the "mouth streptococcus." In their early clas...
متن کاملThe Classification of Hemolytic Streptococci
1. The hemolytic variety of streptococcus is homogeneous, consisting of members that are nearly identical. 2. This homogeneity is most strikingly displayed in the behavior of these streptococci in the complement fixation reaction, all the strains studied reacting in a nearly identical way with all the antisera.
متن کاملThe 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 con...
