A streptococcal isolate can be classified presumptively as GBS on the basis of biochemical tests, including hydrolysis of sodium hippurate (in which 99% of isolates are positive), hydrolysis of bile esculin (in which 99-100% are negative), bacitracin susceptibility (in which 92% are resistant), and production of CAMP factor (in which 98-100% are positive). CAMP factor is a phospholipase produced by GBS that causes synergistic hemolysis with p lysin produced by certain strains ofS. aureus'-Harrison 19th/969Staphylococci produce catalase, which converts hydrogen peroxide into water and oxygen. The catalase test differentiates the staphylococci, which are positive, from the streptococci, which are negative- Jawetz 27th/205Ananthanarayan 10th/210Species or common nameLancefield groupHemolysisLaboratory testS. pyogenesABetaBacitracin-sensitive, PYR test-positive; Ribose not fermntedS. agalactiaeBBetaCAMP test, Hippurate hydrolysisBacitracin Test microbeonline.com Positive: Streptococcus pyogenes Negative: Streptococcus agalactiaeThe bacitracin test is useful for differentiating b-hemolytic Group A streptococci from b-hemolytic non-Group A streptococci. This is important because most streptococcal diseases are caused by Group A streptococci. The bacitracin test can also be used to differentiate the bacitracin-resistant Staphylococcus from the bacitracin-susceptible Micrococcuswww.austincc.edu
