BACKGROUND An epidemiological and entomological study was carried out in Balaghat district, Madhya Pradesh, India to understand the dynamics of forest malaria transmission in a difficult and hard to reach area where indoor residual spray and insecticide treated nets were used for vector control. METHODS This community based cross-sectional study was undertaken from January 2010 to December 20...
A recombinant DNA Plasmodium vivax sporozoite vaccine containing the repeating region of the Salvador I strain circumsporozoite (CS) protein was produced in Escherichia coli. This vaccine was tested in 13 naive volunteers at doses of 10-1,000 micrograms. No serious adverse reactions were noted. None of 4 volunteers receiving the 10 micrograms dose developed antibodies measurable by ELISA. Six o...
The feasibility of identifying parasite DNA and specific mRNAs from wild-caught Anopheles dirus mosquitoes was assessed using dried mosquito salivary glands preserved on filter paper. We were able to detect Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae and Plasmodium knowlesi DNA by conventional PCR and, furthermore, detected P. falciparum gametocyte-specific genes, pfg377 and pf...
To elucidate the structural basis of T cell recognition of hapten-modified antigenic peptides, we studied the interaction of the T1 T cell antigen receptor (TCR) with its ligand, the H-2Kd-bound Plasmodium berghei circumsporozoite peptide 252-260 (SYIPSAEKI) containing photoreactive 4-azidobenzoic acid (ABA) on P. berghei circumsporozoite Lys259. The photoaffinity-labeled TCR residue(s) were ma...
بررسی بیان ژنهای دخیل در سیستم دفاعی گندم نسبت به mycosphaerella graminicola با استفاده از cdna-aflp
aflp یک ابزار قدرتمند برای تشخیص رونوشت هایی با فراوانی کم است و می تواند بعنوان یک روش کارآمد برای جداسازی ژنهایی که بطور متمایز بیان می شوند، بکار رود. بنابراین القا متمایز ژنها در گندم ( رقم چمران و مرودشت) در پاسخ به قارچ m.graminicola بوسیله آنالیز cdna-aflp مورد مطالعه قرار گرفت . در ابتدا گیاهان بوسیله بیمارگر مایه زنی شدند. نمونه برداری در 6 نقطه زمانی(0، 12، 24، 48، 72 و 96 ساعت) بعد ا...
Most studies of gene expression in Plasmodium have been concerned with asexual and/or sexual erythrocytic stages. Identification and cloning of genes expressed in the preerythrocytic stages lag far behind. We have constructed a high quality cDNA library of the Plasmodium sporozoite stage by using the rodent malaria parasite P. yoelii, an important model for malaria vaccine development. The tech...
