We show here that following intravenous infection of mice, S. aureus disseminates rapidly into organ tissues and elicits abscess lesions that develop over weeks but cannot be cleared by the host. Staphylococci grow as communities at the center of abscess lesions and are enclosed by pseudocapsules, separating the pathogen from immune cells. By testing insertional variants in genes for cell wall-anchored surface proteins, we are able to infer the stage at which these molecules function. Fibrinogen-binding proteins ClfA and ClfB are required during the early phase of staphylococcal dissemination. The heme scavenging factors IsdA and IsdB, as well as SdrD and protein A, are necessary for abscess formation. Envelope-associated proteins, Emp and Eap, are either required for abscess formation or contribute to persistence. Fluorescence microscopy revealed Eap deposition within the pseudocapsule, whereas Emp was localized within staphylococcal abscess communities. Antibodies directed against envelope-associated proteins generated vaccine protection against staphylococcal abscess formation. Thus, staphylococci employ envelope proteins at discrete stages of a developmental program that enables abscess formation and bacterial persistence in host tissues.—Cheng, A. G., Kim, H.
