A new development in malaria:

瘧疾的最新研究進(jìn)展：

“Plasmodium vivax, the world’s most common malaria parasite, now infects people previously considered to be resistant.”

“間日瘧原蟲(chóng)是世上最常見(jiàn)的瘧疾寄生蟲(chóng)，現(xiàn)在，這種寄生蟲(chóng)也會(huì)感染那些之前被認(rèn)為抗瘧疾病的人。”

Peter Zimmerman from Case Western Reserve University school of medicine spoke at the AAAS meeting in Washington on February 19th.

在2月19日，來(lái)自凱斯西儲(chǔ)大學(xué)醫(yī)學(xué)院的皮特·齊默曼于華盛頓在美國(guó)科學(xué)發(fā)展協(xié)會(huì)會(huì)議中發(fā)表講話。

“So, red blood cells of most African people do not express the Duffy blood-group protein. Now, the Duffy blood-group protein is essentially necessary for Plasmodium vivax to get into the red cell. Duffy-negative Africans have been considered to be resistant to Plasmodium vivax.”

“因此，大部分非洲人的紅細(xì)胞不會(huì)表達(dá)達(dá)菲蛋白?，F(xiàn)在間日瘧原蟲(chóng)必須依靠達(dá)菲蛋白進(jìn)入紅細(xì)胞。不表達(dá)達(dá)菲蛋白的非洲人曾被認(rèn)為是不會(huì)感染間日瘧原蟲(chóng)的?！?/div>

Zimmerman studied Malagasy populations on Madagascar. He found that 10 percent of Duffy-negative subjects were in fact infected with Plasmodium vivax.

齊默曼研究了馬達(dá)加斯加上土地上的馬達(dá)加斯加人。他發(fā)現(xiàn)10%沒(méi)有達(dá)菲蛋白的人實(shí)際上都被間日瘧原蟲(chóng)感染了。

在2月19日，來(lái)自凱斯西儲(chǔ)大學(xué)醫(yī)學(xué)院的皮特·齊默曼于華盛頓在美國(guó)科學(xué)發(fā)展協(xié)會(huì)會(huì)議中發(fā)表講話。

“So we’ve shown that Plasmodium vivax has cleared Duffy negativity. If Plasmodium vivax is evolving to learn how to infect the Duffy-negative red cell, then a large continent of people suddenly becomes susceptible to a new form of malaria.”

因此我們證明了不表達(dá)達(dá)菲蛋白的人已經(jīng)不再能抵抗間日瘧原蟲(chóng)了。如果間日瘧原蟲(chóng)進(jìn)化到可以影響不表達(dá)達(dá)菲蛋白的紅細(xì)胞，那么突然之間，這片大陸上就會(huì)有很多人可能患上了一種新的虐疾病。
