Description: Genetic manipulations of insect populations for pest control have been advocated for some time, but there are few cases where manipulated individuals have been released in the field and no cases where they have successfully invaded target populations. Population transformation using the intracellular bacterium Wolbachia is particularly attractive because this maternally-inherited agent provides a powerful mechanism to invade natural populations through cytoplasmic incompatibility. When Wolbachia are introduced into mosquitoes, they interfere with pathogen transmission and influence key life history traits such as lifespan. Here we describe how the wMel Wolbachia infection, introduced into the dengue vector Aedes aegypti from Drosophila melanogaster, successfully invaded two natural A. aegypti populations in Australia, reaching near-fixation in a few months following releases of wMel-infected A. aegypti adults. Models with plausible parameter values indicate that Wolbachia-infected mosquitoes suffered relatively small fitness costs, leading to an unstable equilibrium frequency 〈30% that must be exceeded for invasion. These findings demonstrate that Wolbachia-based strategies can be deployed as a practical approach to dengue suppression with potential for area-wide implementation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoffmann, A A -- Montgomery, B L -- Popovici, J -- Iturbe-Ormaetxe, I -- Johnson, P H -- Muzzi, F -- Greenfield, M -- Durkan, M -- Leong, Y S -- Dong, Y -- Cook, H -- Axford, J -- Callahan, A G -- Kenny, N -- Omodei, C -- McGraw, E A -- Ryan, P A -- Ritchie, S A -- Turelli, M -- O'Neill, S L -- England -- Nature. 2011 Aug 24;476(7361):454-7. doi: 10.1038/nature10356.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Bio21 Institute, Department of Genetics, The University of Melbourne, Victoria 3010, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21866160" target="_blank"〉PubMed〈/a〉

Description: Dengue fever is the most important mosquito-borne viral disease of humans with more than 50 million cases estimated annually in more than 100 countries. Disturbingly, the geographic range of dengue is currently expanding and the severity of outbreaks is increasing. Control options for dengue are very limited and currently focus on reducing population abundance of the major mosquito vector, Aedes aegypti. These strategies are failing to reduce dengue incidence in tropical communities and there is an urgent need for effective alternatives. It has been proposed that endosymbiotic bacterial Wolbachia infections of insects might be used in novel strategies for dengue control. For example, the wMelPop-CLA Wolbachia strain reduces the lifespan of adult A. aegypti mosquitoes in stably transinfected lines. This life-shortening phenotype was predicted to reduce the potential for dengue transmission. The recent discovery that several Wolbachia infections, including wMelPop-CLA, can also directly influence the susceptibility of insects to infection with a range of insect and human pathogens has markedly changed the potential for Wolbachia infections to control human diseases. Here we describe the successful transinfection of A. aegypti with the avirulent wMel strain of Wolbachia, which induces the reproductive phenotype cytoplasmic incompatibility with minimal apparent fitness costs and high maternal transmission, providing optimal phenotypic effects for invasion. Under semi-field conditions, the wMel strain increased from an initial starting frequency of 0.65 to near fixation within a few generations, invading A. aegypti populations at an accelerated rate relative to trials with the wMelPop-CLA strain. We also show that wMel and wMelPop-CLA strains block transmission of dengue serotype 2 (DENV-2) in A. aegypti, forming the basis of a practical approach to dengue suppression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walker, T -- Johnson, P H -- Moreira, L A -- Iturbe-Ormaetxe, I -- Frentiu, F D -- McMeniman, C J -- Leong, Y S -- Dong, Y -- Axford, J -- Kriesner, P -- Lloyd, A L -- Ritchie, S A -- O'Neill, S L -- Hoffmann, A A -- England -- Nature. 2011 Aug 24;476(7361):450-3. doi: 10.1038/nature10355.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biological Sciences, The University of Queensland, Brisbane, Queensland 4072, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21866159" target="_blank"〉PubMed〈/a〉

Description: The mosquito Culex quinquefasciatus poses a substantial threat to human and veterinary health as a primary vector of West Nile virus (WNV), the filarial worm Wuchereria bancrofti, and an avian malaria parasite. Comparative phylogenomics revealed an expanded canonical C. quinquefasciatus immune gene repertoire compared with those of Aedes aegypti and Anopheles gambiae. Transcriptomic analysis of C. quinquefasciatus genes responsive to WNV, W. bancrofti, and non-native bacteria facilitated an unprecedented meta-analysis of 25 vector-pathogen interactions involving arboviruses, filarial worms, bacteria, and malaria parasites, revealing common and distinct responses to these pathogen types in three mosquito genera. Our findings provide support for the hypothesis that mosquito-borne pathogens have evolved to evade innate immune responses in three vector mosquito species of major medical importance.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3104938/" 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/PMC3104938/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bartholomay, Lyric C -- Waterhouse, Robert M -- Mayhew, George F -- Campbell, Corey L -- Michel, Kristin -- Zou, Zhen -- Ramirez, Jose L -- Das, Suchismita -- Alvarez, Kanwal -- Arensburger, Peter -- Bryant, Bart -- Chapman, Sinead B -- Dong, Yuemei -- Erickson, Sara M -- Karunaratne, S H P Parakrama -- Kokoza, Vladimir -- Kodira, Chinnappa D -- Pignatelli, Patricia -- Shin, Sang Woon -- Vanlandingham, Dana L -- Atkinson, Peter W -- Birren, Bruce -- Christophides, George K -- Clem, Rollie J -- Hemingway, Janet -- Higgs, Stephen -- Megy, Karine -- Ranson, Hilary -- Zdobnov, Evgeny M -- Raikhel, Alexander S -- Christensen, Bruce M -- Dimopoulos, George -- Muskavitch, Marc A T -- F31 AI080161/AI/NIAID NIH HHS/ -- F31 AI080161-01A1/AI/NIAID NIH HHS/ -- HHSN266200400001C/AO/NIAID NIH HHS/ -- HHSN266200400001C/PHS HHS/ -- HHSN266200400039C/AI/NIAID NIH HHS/ -- HHSN266200400039C/PHS HHS/ -- P20 RR017686/RR/NCRR NIH HHS/ -- P20 RR017686-01/RR/NCRR NIH HHS/ -- R01 AI019769/AI/NIAID NIH HHS/ -- R01 AI019769-26/AI/NIAID NIH HHS/ -- R01 AI059492/AI/NIAID NIH HHS/ -- R01 AI059492-05/AI/NIAID NIH HHS/ -- R01 AI061576/AI/NIAID NIH HHS/ -- R01 AI061576-08/AI/NIAID NIH HHS/ -- R01 AI067698/AI/NIAID NIH HHS/ -- R01 AI067698-05/AI/NIAID NIH HHS/ -- R01 AI078997/AI/NIAID NIH HHS/ -- R01 AI078997-02/AI/NIAID NIH HHS/ -- R01 AI095842/AI/NIAID NIH HHS/ -- R01 AI19769/AI/NIAID NIH HHS/ -- R01 AI59492/AI/NIAID NIH HHS/ -- R01 AI67698/AI/NIAID NIH HHS/ -- R21 AI067642/AI/NIAID NIH HHS/ -- R21 AI067642-01/AI/NIAID NIH HHS/ -- T01CCT622892/PHS HHS/ -- T32 A107536/PHS HHS/ -- T32 AI007414/AI/NIAID NIH HHS/ -- T32 AI007417/AI/NIAID NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Oct 1;330(6000):88-90. doi: 10.1126/science.1193162.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomology, Iowa State University, Ames, IA 50011, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20929811" target="_blank"〉PubMed〈/a〉

Description: Sheep (Ovis aries) are a major source of meat, milk, and fiber in the form of wool and represent a distinct class of animals that have a specialized digestive organ, the rumen, that carries out the initial digestion of plant material. We have developed and analyzed a high-quality reference sheep genome and transcriptomes from 40 different tissues. We identified highly expressed genes encoding keratin cross-linking proteins associated with rumen evolution. We also identified genes involved in lipid metabolism that had been amplified and/or had altered tissue expression patterns. This may be in response to changes in the barrier lipids of the skin, an interaction between lipid metabolism and wool synthesis, and an increased role of volatile fatty acids in ruminants compared with nonruminant animals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4157056/" 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/PMC4157056/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jiang, Yu -- Xie, Min -- Chen, Wenbin -- Talbot, Richard -- Maddox, Jillian F -- Faraut, Thomas -- Wu, Chunhua -- Muzny, Donna M -- Li, Yuxiang -- Zhang, Wenguang -- Stanton, Jo-Ann -- Brauning, Rudiger -- Barris, Wesley C -- Hourlier, Thibaut -- Aken, Bronwen L -- Searle, Stephen M J -- Adelson, David L -- Bian, Chao -- Cam, Graham R -- Chen, Yulin -- Cheng, Shifeng -- DeSilva, Udaya -- Dixen, Karen -- Dong, Yang -- Fan, Guangyi -- Franklin, Ian R -- Fu, Shaoyin -- Fuentes-Utrilla, Pablo -- Guan, Rui -- Highland, Margaret A -- Holder, Michael E -- Huang, Guodong -- Ingham, Aaron B -- Jhangiani, Shalini N -- Kalra, Divya -- Kovar, Christie L -- Lee, Sandra L -- Liu, Weiqing -- Liu, Xin -- Lu, Changxin -- Lv, Tian -- Mathew, Tittu -- McWilliam, Sean -- Menzies, Moira -- Pan, Shengkai -- Robelin, David -- Servin, Bertrand -- Townley, David -- Wang, Wenliang -- Wei, Bin -- White, Stephen N -- Yang, Xinhua -- Ye, Chen -- Yue, Yaojing -- Zeng, Peng -- Zhou, Qing -- Hansen, Jacob B -- Kristiansen, Karsten -- Gibbs, Richard A -- Flicek, Paul -- Warkup, Christopher C -- Jones, Huw E -- Oddy, V Hutton -- Nicholas, Frank W -- McEwan, John C -- Kijas, James W -- Wang, Jun -- Worley, Kim C -- Archibald, Alan L -- Cockett, Noelle -- Xu, Xun -- Wang, Wen -- Dalrymple, Brian P -- 095908/Wellcome Trust/United Kingdom -- 098051/Wellcome Trust/United Kingdom -- BB/1025360/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/I025328/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/I025360/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/I025506/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- U54 HG003273/HG/NHGRI NIH HHS/ -- WT095908/Wellcome Trust/United Kingdom -- WT098051/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2014 Jun 6;344(6188):1168-73. doi: 10.1126/science.1252806.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉State Key Laboratory of Genetic Resources and Evolution, Kunming Institute of Zoology, Chinese Academy of Sciences, Kunming 650223, China.
