Question

REMEMBER - include gram reaction and microscopic morphology; description on primary plating media and any appropriate specialized media; benchside rapid tests; biochemical tests; and any appropriate automated systems. Each flowchart should be different and unique; even if same organism.

my unknown is streptococcus pyogenes please I need all the help possible thank you

Answer 1

Streptococcus pyogenes a reaction . It is a gram positive bacterium that grows in pairs or chains Micro.cobie mondhology :- White greyish colour and have a diameter of 70.5mm, and are surrounded by a zone of B-hemolysis that is o 2.18 kusines' as langel as colomy diameter Culturing techniques : - Streptococcus are generally grown on agar media Supplemented with blood. Selective media such as agar media that contains phenyl, ethyl alcohol ex Columbia agar with colistin and malidixic and also provide adequate culturing conditions for S. pyogener

Benchside rabid tests. Throat swabs for culture were inoculated on to blood agar plates and incubated in e a cor incubator at 37°C Crouping of beta-hemolytic Streptococaiwezo done by Coagglutination technique after the antigen was extracted by the micronitrous and extraction method. Biochemical tests Basic characteristics Properties CAMP -ve 2) Capsule Capsulated 3) Catalase 4) Coram staining tve 5) Hemolysis B-hemolytic 6) Motility Non mottle + Oxidative fermentative Facultative anaerobes 3) PYR. tve 9 Urease -ve 16) VP [Voges Proskauen] - ve 11) 6.5 % Nail growth ave ve

Automated systems New commencial systems. for the identification of streptococa include the FDA approved Vexigene Cram-positive blood culture nupeic aid test and the Film Array platform for the direct identification of bacterial pathogens from blood culture bottles. Highly favourable results were obtained from these systems.
