Extensive diversity in the allelic frequency of Plasmodium falciparum merozoite surface proteins and glutamate-rich protein in rural and urban settings of southwestern Nigeria

Table 2 Distribution of MSP-1 allelic family in rural and urban communities

	MSP-1 family	No. of samples positively amplified	Allelic size (bp)	Frequency (%)	MOI
Rural (n = 151)	RO33	11	150–250	7.3	2.8
	MAD20	5	150–200	3.3
	K1	4	150–350	2.6
	RO33 + MAD20	4		2.6
	RO33 + K1	3		2.0
	RO33 + MAD20 + K1	124		82.1
Urban (n = 30)	RO33	3	150	10.0	2.6
	MAD20	3	150–250	10.0
	RO33 + K1	3		10.0
	RO33 + MAD20 + K1	21		70.0

Numbers sampled cannot add up since a sample can amplify in more than 1 family
