title: The chemotactic effect of Bacteroides fragilis lipopolysaccharide.
abstract: The atypical Bacteroides fragilis lipopolysaccharide is chemotactic for polymorphonuclear leukocytes. The chemotactic activity is mediated by complement activated through the alternative pathway. This mediator has been isolated. It is a polypeptide with a molecular weight of 16,000 and is most likely the complement component C5a.
