FIG. 2.
Comparison of in vitro inhibition of invasion due to neuraminidase treatment (x axis) and trypsin treatment (y axis) of target erythrocytes for 38 P. falciparum field isolates from The Gambia (closed squares) and 11 laboratory-maintained isolates from broad geographical origins (open squares) (4). Lines indicate 50% inhibition by enzyme treatment for visual clarity.
