- The test detects the amino acid serine that has been cleaved from the hippuric acid. The second tube is positive for hippurate hemolysis and presumptive identification of GBS. Group B Streptococcus (GBS) are generally beta hemolytic on blood agar plates (right hand side).The colonies of GBS are gray to whitish-gray surrounded by a weak zone of beta hemolysis of the red blood cells in the culture medium.hese results indicate we have identified a group B Streptococcus. This is a picture of an agar plate with growth and hemolytic activity of group B streptococci (GBS) (on the left) and group A streptococci (GAS)(on the right).

Strep Rash Causes of strep rash. Strep rash is caused by the same species of bacteria which causes strep throat, i.e. Streptococcus pyogenes, or also known as group A streptococcus. The reddish rashes associated with strep rash is caused due to the reaction of a toxin secreted by the bacteria.The bacterial infection transfers from a patient to others through the droplets which are thrown into the air when an infected individual coughs or sneezes.trep Rash. Strep rash is nothing but scarlet fever which is accompanied by a strep throat. The condition is recognized by the development of a bright red rash which occurs almost throughout the body.

Scarlet Fever: A Group A Streptococcal Infection Scarlet fever – or scarlatina – is a bacterial infection caused by group A Streptococcus or “group A strep.” These bacteria cause many types of infections, including strep throat and skin infections. Certain strep bacteria produce a toxin (poison) that can cause a red rash—the “scarlet” of scarlet fever.

Streptococci were divided into groups in 1933 by mixing the strains with antibodies that were produced in rabbits.roup B strep is not a cause of birth defects or autism and is not a sexually transmitted disease. Although babies may contract infections by contact with contaminated hands, washing with simple soap and water eliminates the organism. Group B strep is not contagious through coughing or sneezing.
