Bacteria Lowers Mosquito Transmission of Malaria, Dengue

细菌降低蚊子传播疟疾、登革热几率

The human microbiome is the community of tiny organisms that live on us and inside us. These critters play vital roles in our health. They calibrate our immune systems, ward off pathogenic bacteria, even affect our weight. But if we stop the navel gazingliterally, because some scientists are actually measuring belly button bacteriatheres a whole lot to be found in the microbiomes of other organisms, too.

人体正常菌群是生存于我们体表与体内的微小生物群体。这些小生物在我们的身体健康中扮演至关重要的角色。它们帮助我们校准免疫系统、抵御病原细菌、甚至还会影响我们的体重。但如果我们不再紧盯着肚脐看说真的,因为确实有一些科学家真的在测量肚脐细菌在其他机体的生物菌群中也有很多亟待被发现。

Take the pesky mosquito. A few years back, scientists found a soil microbe calledChromobacterium Csp_P living in the guts of mosquitoes in Panama. Upon further study, the researchers say this mosquito-occupant could be a remarkably versatile weapon to fight malaria and dengue fever. Because Chromobacterium shortens the lifespan of disease-transmitting mosquito species that harbor it; and kills their larvae outright. It also reduces mosquitoes ability to catch the dengue virus, or the malarial parasite; and it kills both pathogens in the lab. Those findings are in the journal PLoS Pathogens.

就拿讨厌的蚊子来说吧。几年前,科学家在巴拿马发现一种被称为色素细菌Csp P土壤微生物而它们竟有勇气寄生在蚊子上。在进一步的研究中,研究人员表示这种寄生蚊虫者可能是对抗疟疾和登革热的一个很全能的武器。因为色素细菌会缩短它们寄生的那些传播疾病的蚊虫类生物的寿命,并且会直接杀死蚊虫幼虫。同时,它们还可以降低蚊子感染登革热病毒或疟疾寄生虫的能力。在实验室,它们还杀死了两种病毒的病原体。这些发现被刊发在《公共科学图书馆:病原体》的期刊上。【约瑟路易斯拉米雷斯等科学家:色素细菌Csp P能减少病媒蚊子对疟疾和登革热的感染并有昆虫病原细菌和体外抑制活动】

The researchers say this Chromobacterium strain could someday guide the development of new drugs. Or serve as a more environmentally-friendly stand-in for pesticides. But they also say that, as with many disease-control strategies, theres no one silver bullet. Drugs, vaccines, and education will still be crucial to keeping mosquito-borne killers in check. Along with good old vector control: in this case, fighting bugs with bugs.

研究人员称这种色素细菌菌株将来可能引导我们指导新药,或者作为一个更环保的杀虫剂替身服务人类。但他们同时也表示,与其它许多疾病控制策略一样,它也并非一个全能良方。药物、疫苗和教育仍将是约束蚊媒杀手的关键。如同实用的老一套传病媒介控制:这种情况下,还是要以虫治虫。
