Figure 1. Genotyping tree.
MLVA genotyping of isolates recovered from patients suffering chronic rhinosinusitis from five different geographic locations (B. Brugg; Z. Zagreb; P. Paris; L. London; G. Geneva). Control isolates (CTL) from Geneva patients are also depicted (a single isolate per patient is shown). Categories are indicated between brackets. Scale displays the relations between isolates. Isolates with a maximal distance 0.1 [30] are considered as clonal. CRSsNP = Chronic Rhinosinusitis without Nasal Polyposis group; NP1-2-3 = Nasal Polyposis grade 1-2-3 groups; Ctl = control group.
