Phylogenomic analysis reveals a lack of global population structuring in Pneumocystis jirovecii. Each symbol represents a single P. jirovecii isolate. The color-coding scheme indicates the region (city or state and country) in which the isolate was obtained. There is no clustering by location but instead an intermixing of isolates from diverse geographic locations, consistent with a lack of geographic structure. The phylogenetic tree was estimated from genome-wide SNP differences of Pneumocystis jirovecii isolates sequenced in this project (832,669 segregating sites).
