TABLE. Distribution of R0 and R2 fragments of glutamate-rich protein of various sizes amplified by nested polymerase chain reaction from Plasmodium falciparum isolates collected in Porto Velho, state of Rondônia, at two time points.
| Amplified fragments | Time point-1 np/n (%) | Time point-2 np/n (%) | Fragments np/n (%) | |
|---|---|---|---|---|
| R0 region | ||||
| R0a | 77/77 (100) | 49/49 (100) | 126/126 (100) | |
| R2 region | ||||
| R2a | 28/79 (35.4) | 12/49 (24.5) | 40/128 (31.2) | |
| R2b | 19/79 (24) | 18/49 (36.7) | 37/128 (29) | |
| R2c | 6/79 (7.6) a | 9/49 (18.4) b | 15/128 (11.7) c | |
| R2d | 26/79 (33) | 10/49 (20.4) | 36/128 (28.1) | |
a : p < 0.0001, R2c vs. R2a, p = 0.004, R2c vs. R2b, p < 0.0001, R2c vs. R2d; b : p = 0.04, R2b vs. R2c; c : p = 0.0001, R2c vs. R2a, p = 0.0006, R2c vs. R2bp, p = 0.001, R2c vs. R2d; np: number of amplified fragments.
