title: Chemotaxigenesis by encapsulated Staphylococcus aureus M.
abstract: Although encapsulated Staphylococcus aureus M is not opsonized by normal human serum, as a chemotaxigen this organism behaved similarly to an unencapsulated variant strain. For optimal chemotaxigenesis, an intact classical complement pathway was required, and C5a appeared to be the major chemotaxin.
