Persistence and variability of Stenotrophomonas maltophilia strains in 11 patients with repeated episodes of infection or colonization with this organism. S. maltophilia recovered is indicated by a ◆(identical isolates from the same patient), ◇(different isolate from a single patient) or O (no isolate available). Distinct S. maltophilia isolates are identified by numbers, and a letter was added when a closely related strain was observed. + = time at which sputum specimens were obtained.
