From: Strongyloides stercoralis genotyping in a human population in southwestern Iran
Principal component analysis of whole-genome sequences from Iran and published sequences from Asia. The geographical origin is color-coded. The numbers with the Iranian numbers are the worm numbers (cf. Additional file 1: Fig. 1 and Figs. 2 and 3). The samples from Myanmar and Japan are from [36], the samples from Thailand are from [16], and the samples from Cambodia are from [14]. Note that the sequences from [19] (from Southern China) and the sequences from [35] (from the USA) were not included because they are so different that they dominated the PCA such that no other differences were visible in PC1 and PC2
