    Description: Metarhizium anisopliae infects mosquitoes through the cuticle and proliferates in the hemolymph. To allow M. anisopliae to combat malaria in mosquitoes with advanced malaria infections, we produced recombinant strains expressing molecules that target sporozoites as they travel through the hemolymph to the salivary glands. Eleven days after a Plasmodium-infected blood meal, mosquitoes were treated with M. anisopliae expressing salivary gland and midgut peptide 1 (SM1), which blocks attachment of sporozoites to salivary glands; a single-chain antibody that agglutinates sporozoites; or scorpine, which is an antimicrobial toxin. These reduced sporozoite counts by 71%, 85%, and 90%, respectively. M. anisopliae expressing scorpine and an [SM1](8):scorpine fusion protein reduced sporozoite counts by 98%, suggesting that Metarhizium-mediated inhibition of Plasmodium development could be a powerful weapon for combating malaria.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4153607/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4153607/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fang, Weiguo -- Vega-Rodriguez, Joel -- Ghosh, Anil K -- Jacobs-Lorena, Marcelo -- Kang, Angray -- St Leger, Raymond J -- 5R21A1079429-02/PHS HHS/ -- R01 AI031478/AI/NIAID NIH HHS/ -- R21 AI079429/AI/NIAID NIH HHS/ -- R21 AI088033/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2011 Feb 25;331(6020):1074-7. doi: 10.1126/science.1199115.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomology, University of Maryland, 4112 Plant Sciences Building, College Park, MD 20742, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21350178" target="_blank"〉PubMed〈/a〉
