London, December 21 (Xinhua) ' The reporter is yellow) Under the great background of the global warming, a lot of people are afraid the spread ability of malaria will rise and strengthen with the temperature. But a latest research reveals that may not be like this, the temperature raises the spread ability that may weaken malaria instead. The " biological communication " magazine that the Royal Society hosts publishes saying on the 21st, the researchers of American Pennsylvania State University are under different temperature conditions such as 20, 22, 24 and 26 ��, have trained and infected the mosquito of plasmodium. The result reveals, when the temperature is higher, though the growth of plasmodium accelerates, but can form the sporular proportion with contagiousness to drop instead finally. Spore is plasmodium's final form of development in mosquito's body, plasmodium that development reaches the sporular shape will enter the salivary gland of the mosquito, enter the human body when the mosquito bites the mankind and transmit malaria. Multiple research have already found, the temperature will make plasmodium's growth to raise in mosquito's body accelerate before this, these it is a lot of people that think malaria can travel ability enhanced reason, but the research in the past will not involve the sporular state. According to data of this research, though the development of plasmodium is the sharpest at 26 �� in speed, but it is highest to form the sporular proportion finally at 22 ��, malaria of comprehensive analysis propagates the risk should be biggest at 24 ��. But researchers still show, should infer the true malaria in the world propagate the risk, also need to consider the temperature change bites factors such as the influence of the human habits and acquired characteristics,etc. to the mosquito. Researchers point out, often predict in the discussion about the global warming that thinks malaria will rise and increase with the temperature to propagate the risk, predict, consider the intersection of temperature and change to to influence in many aspects plasmodium in an all-round way, this also needs more careful research.
