Serogrouping single colonies of beta-hemolytic streptococci from primary throat culture plates with nitrous acid extraction and Phadebact streptococcal reagents.
The serogrouping of isolated beta-hemolytic streptococcal colonies from throat cultures by a micronitrous acid extraction method employing Phadebact Streptotoccus Test reagents was compared with results obtained with the direct-plate Phadebact procedure and the autoclave and Streptomyces albus enzyme-lysozyme extraction methods. These data were compared with those from the Lancefield grouping o...
متن کاملDirect-plate serological grouping of beta-hemolytic streptococci from primary isolation plates with the Phadebact streptococcus test.
The grouping of beta-hemolytic streptococcal isolates by a new direct-plate procedure employing Phadebact Streptococcus Test reagents was compared with the results obtained with the 4- and 24-h Phadebact grouping procedure and with the Lancefield grouping obtained with a capillary precipitin test. The new procedure employed a modification of the Phadebact procedure that permitted the grouping o...
متن کاملLatex agglutination testing directly from throat swabs for rapid detection of beta-hemolytic streptococci from Lancefield serogroup C.
A latex agglutination method for the rapid detection of beta-hemolytic streptococci from Lancefield serogroup C in throat swabs from 403 university students with symptomatic pharyngitis was evaluated. Compared with culture, the rapid test was poorly sensitive (34.4%) but very specific (98.4%) in detecting group C beta-hemolytic streptococci. The sensitivity of the rapid test improved with an in...
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 کاملEvaluation of the Culturette Brand Ten-Minute Group A Strep ID technique.
A direct extraction of the antigens of group A beta-hemolytic streptococci from 557 throat swabs was performed by a new microtechnique of the nitrous acid extraction method with the Culturette Brand Ten-Minute Strep ID technique from Marion Scientific, Division of Marion Laboratories, Inc., Kansas City, Mo. This group A latex reagent kit contains the reagents for the micronitrous acid extractio...
