چکیده

متن کاملمقایسه تاثیر آنتی‌بادی‌های ضد میان روده پشه آنوفل استفنسی بر روی چرخه اسپروگونی انگل پلاسمودیوم برگئی در دو سویه از آنوفل استفنسی
Background & Aims: Malaria parasites attach to molecules on midgut surface of Anopheles mosquitoes to continue their life cycle. Here we try to evaluate the effect of anti-Anopheles midgut antibodies on coating these molecules and consequently blocking the transmission cycle of Plasmodium berghei inside their vectors. Materials & Methods: Balb/c mice were immunized with homogenized and degly...
