Figure 1From: Inhibition of trypsin expression in Lutzomyia longipalpis using RNAi enhances the survival of LeishmaniaSpecific trypsin activity in the midguts of Lu. longipalpis. Sand flies were fed with rabbit blood alone or infected with Le. mexicana and trypsin activity (μM/min/mg protein) assayed at 24, 48 and 72 h after the blood feed/infection. Bars represent mean values and standard errors of combined samples derived from 2 independent experiments. Numbers of flies assayed are as indicated by N values. * represents statistical significance at p = 0.002 and ** represents statistical difference at p = 0.015 (U Mann-Whitney).Back to article page
