Abstract

Summary.

Chemotaxis of polymorphonuclear leukocytes (PMNL) in response to cell components of alone or in combination with was evaluated. . produced much more powerful chemotactic factors than . The culture filtrate (CF), outer membrane (OM) preparation, and lipopolysaccharide (LPS) of . slightly stimulated chemotactic activity of PMNL. The culture filtrate and OM preparation were capable of inhibiting the chemotaxis of PMNL in response to the chemotactic factors of . but LPS of . was not able to do so. Reduction by B. fragilis of PMNL chemotaxis in response to . was not specific for . but also occurred in the presence of facultative bacteria. In parallel with chemotaxis, lysozyme release, but not -glucuronidase release, by PMNL was significantly stimulated by . but not by . .
