Total in vitro chemotaxis of human neutrophils in response to cell-free culture supernatant from CP9 (wild type), CP921 (O-antigen deficient), and CP9.137 (capsule deficient) alone and in response to the mixture of supernatants from CP9 plus CP921 and CP9 plus CP9.137. Neutrophil chemotaxis was similar (not less) in response to the mixtures of supernatants from CP9 plus CP921 and CP9 plus CP9.137 compared to when the chemotactic activity due to supernatant from CP9 and CP921 alone and CP9 and CP9.137 alone was averaged (ave.) (n = 2).
