Evaluation of the oxoid dryspot streptococcal grouping kit for grouping beta-hemolytic streptococci.
The latex agglutination kits that are widely used for grouping of beta-hemolytic streptococci in clinical laboratories use liquid latex suspensions. The Oxoid Dryspot kit (Oxoid Ltd., Basingstoke, Hampshire, United Kingdom) uses predispensed latex dried onto reaction cards or cardboard strips. All streptococci of groups A (85 strains), B (87 strains), C (30 strains), D (38 strains), F (23 strai...
متن کاملEvaluation of new streptococcal latex grouping kit.
AIMS To evaluate a new streptococcal latex grouping kit (Shield Diagnostics Ltd) and compare it against an established latex agglutination method (Streptex; Wellcome Diagnostics). METHODS Two hundred and forty seven strains of streptococci and enterococci were tested with each kit by one operator and according to the manufacturer's instructions. Strains failing to group or giving discordant r...
متن کاملStreptococcal Grouping Latex Kit
Clinical, epidemiological and microbiological studies have conclusively shown that the diagnosis of streptococcal infections based on clinical symptoms always requires microbiological verification. Beta-haemolytic streptococci are the most frequently isolated human pathogens among the representatives of the genus Streptococcus. Nearly all the beta-haemolytic streptococci possess specific carboh...
متن کاملBacitracin and coagglutination for grouping of beta-hemolytic streptococci.
Bacitracin may be used for presumptive differentiation of group A from other beta-hemolytic streptococci. Whatever criteria are used for the test, a small number of erroneous results will be obtained. With the 1,161 strains studied in this laboratory, using a zone of 10 mm or greater as indicative of group A was better than using Maxted's original criterion of any zone of inhibition for group A...
متن کاملSimplified extraction procedure for serological grouping of beta-hemolytic streptococci.
An adaptation of the nitrous acid extraction of streptococci proved to be a reliable and practical method for the preparation of extracts for routine serological group identification. The extracts of all groups tested gave strong capillary precipitin reactions as well as reactions of double diffusion in gel. For routine grouping, extracts were prepared from the first one-half-plate subculture o...
