Com alteração no gene, cientistas criam mosquito da dengue sem asas

da Efe (fonte: UOL)

Uma nova variedade de mosquitos modificados geneticamente para não voar deve refrear a transmissão do vírus da dengue, segundo um estudo de pesquisadores das universidades de Oxford e da Califórnia.

O experimento, publicado hoje na revista “Proceedings of the National Academy of Sciences”, criou uma variedade de mosquito cujas fêmeas são incapazes de voar devido à interrupção provocada do desenvolvimento das suas asas.

Os machos dessa variedade de sintomas visíveis de sua alteração genética mas, quando se acasalam com fêmeas selvagens, os mosquitos fêmea da geração seguinte já nascem sem poder voar.

Até agora, o experimento só foi realizado em laboratórios, mas se espera que a nova variedade desses insetos possa ser solta à natureza em 2011.

Segundo indicou Luke Alphey, pesquisador da empresa Oxford Insect Technologies (Oxitec) associada à universidade britânica, essa libertação representaria o desaparecimento dos mosquitos nativos entre seis e nove meses.

A febre da dengue, um vírus transmitido pela picada da fêmea do mosquito Aedes aegypti, afeta a cada ano entre 50 e 100 milhões de pessoas.

Embora haja estudos em andamento sobre a prevenção e cura da dengue, o uso generalizado de uma vacina contra o vírus ainda levará muitos anos, assegura Alphey. O pesquisador opina que “até então, o controle do mosquito será a única forma de controlar a doença”.

“Se reduzirmos o número de mosquitos, poderemos reduzir a transmissão da dengue e com isso a mortalidade de pessoas”, ressalta em comunicado outro dos membros do projeto, Anthony James, professor de microbiologia e genética molecular na Universidade da Califórnia.

A proposta dessa equipe representa, além disso, uma alternativa segura e eficiente para combater a dengue frente às inseticidas, “que sempre deixam resíduos tóxicos”, acrescenta Alphey.

Os pesquisadores destacaram também que todos os habitantes das áreas tratadas se beneficiariam com a medida, e concordam na possibilidade de aplicá-la a outros espécies de mosquitos transmissores de doenças como a malária ou a febre do Nilo Ocidental.

Os países com mais casos de dengue registrados entre 1995 e 2008 foram Brasil, Colômbia, El Salvador, Nicarágua, Guatemala, Honduras, México, Peru e Venezuela. Além disso, a doença se difundiu consideravelmente nos últimos cinco anos na Argentina, Bolívia, Costa Rica e Paraguai.

muito interessante mesmo essa pesquisa, pois so com trabalhos de cientistas mesmo para ajuda, pois a populção mesmo que bem informada não tem conciencia do perigo.
Na materia se fala ja para 2011 e isso poderáchegar ao brasil tambem ja no ano que vem? e como seria a districuição do mosquito.

grato pela atenção

Fico pensando nos dispêndios financeiros e no tempo, estudo, cuidados e atenção dedicados à proteção de espécies animais ameaçadas de extinção. Mas vetores perigosos e atuantes como baratas, formigas, mosquitos, moscas, pulgas, mesmo sob combate intenso e continuado, nunca estiveram sob risco. É fantástico!
