Serum glucose agar, a transport medium for Streptococcus pyogenes.
When planning an epidemiological study of streptococcal infection, we were recommended to try serum glucose agar which had proved a useful transport medium in another study.' We compared serum glucose agar with Stuart's transport medium, which was our laboratory's usual transport medium for delicate organisms and with dry serum-coated swabs. We also considered the commercially available systems...

متن کاملGlucose and galactose metabolism in Streptococcus pyogenes.
Studies initially concerned with the role of nutrient carbohydrates in the formation of capsular hyaluronic acid by various strains of Streptococcus pyogenes led to the finding that the end products of glucose and galactose dissimilation in these organisms differ quantitatively (Steele et al., 1954). This paper is a report of further investigations on the latter aspect of the carbohydrate metab...
متن کاملThe Serum Opacity Reaction of Streptococcus Pyogenes
Investigation into the antigenicity of streptococcal lipoproteinase has revealed the existence of multiple, immunologically distinct enzymes. Each lipoproteinase identified was found to be strain specific in that it was found only in strains of a particular T-agglutination pattern. In some T patterns, all streptococci of that T pattern which were examined shared a common lipoproteinase antigen....
متن کاملStreptococcus pyogenes ( Group A Streptococcus )
Group A streptococcus (GAS) is synonymous with Streptococcus pyogenes, the only species within this group of β-hemolytic streptococci. GAS is one of the leading pathogenic bacteria that infects children and adolescents, and is associated with a wide spectrum of infections and disease states. Worldwide, there are estimated to be >600 million cases of GAS pharyngitis (“strep throat”) and >100 mil...
