Amino acid sequence comparison of CSP from P. vivax. Amino acid sequences previously found in Chinese P. vivax isolates, determined in the present study and from Indonesia were analyzed. The Genbank database accession numbers are as follows: Indonesia (AFI80542 the sequence was collected in 2003 in Borneo Indonesia), U08977(the sequence was collected in 1994 in Guizhou, China), VK210 (M28746). HNZK1, HNZMD1, HNNY1-8, HNSQ1-14, 18, 21, 26 were collected in 2011 in Henan,China. Case 2013 and txry2013 were from the present study.
