Schematic representation of the single-strand conformation polymorphism (SSCP) patterns of four variable regions used to type Pneumocystis jirovecii. Each lane corresponds to a hypothetical sample. All simple patterns with two bands for each region are shown. Each uppercase letter represents a simple SSCP pattern. For each region, the complex SSCP pattern A,B corresponding to the superimposition of simple patterns A and B is represented. The complex ITS1 pattern A,B, is demonstrated, in which pattern A is more abundant than pattern B. Reprinted with permission from reference 32. Hauser et al. 2001, AIDS:15(4):461–466.
