What is catalse positive strep or staph?

Catalase positive strep or staph refers to bacterial species that produce the enzyme catalase, which breaks down hydrogen peroxide into water and oxygen. Among these, Staphylococcus species (such as Staphylococcus aureus) are catalase positive, while Streptococcus species are catalase negative. The presence of catalase is a key differentiating factor in laboratory identification, as it helps distinguish staphylococci from streptococci. This characteristic can aid in diagnosing infections and determining appropriate treatment options.
