Comparison of the antibody responses to Plasmodium vivax and Plasmodium falciparum antigens in residents of Mandalay, Myanmar

Table 4 Positive rates of Circumsporozoite protein (CSP) of P. vivax

	Antigen	No. Examined	No. Positive	Positive rate (%)
Group I	¹VK210	52	12	23.1
	²VK247	52	5	9.6
Group II	VK210	60	24	40.0
	VK247	60	13	21.7

¹Isolates that reacted with synthetic peptide carrying the amino acid sequence [GDRA(D/G)GQPA] of the dominant form of P. vivax CSP.
²Isolates that reacted with synthetic peptide carrying the amino acid sequence [ANGA(G/D)(N/D)QPG] of the variant form of P. vivax CSP.
* Significant difference between Group I and Group II results (Fisher's two-tailed P = 0.6551)
