三日疟原虫

结果表明：该系统特异性强，除间日疟原虫外，恶性疟原虫（P.f.）、三日疟原虫（P.m.）及正常人血DNA样本均无此扩增带出现。

The results showed that a 120 base pairs ( bp ) DNA fragment of P.vivax was amplified . No amplification was observed with P. falciparum , P. malariae and human DNA .

这组科学家建议医生把诊断为感染了三日疟原虫的患者视为可能感染了诺氏疟原虫加以治疗。

The researchers recommend that doctors treat patients diagnosed with P.malariae as potentially having P.knowlesi .

疟疾有四种类型：间日疟原虫、三日疟原虫、卵形疟原虫和恶性疟原虫。

There are four types of human malaria : Plasmodium vivax , P.malariae , P.ovale and P.falciparum .

也有些晚期滋养体有易于形成带状的趋势，接近三日疟原虫的带状晚期滋养体。

Some late trophozoites had a trend to form " band " that are typical for P. malariae .

结果间日疟原虫、恶性疟原虫和三日疟原虫感染血样中分别扩增出104bp、102bp和115bp预期大小的特定扩增带。

Results 104 bp , 102 bp and 115 bp DNA fragments expected were amplified from the blood samples of patients with P. vivax , P. falciparum and P. malariae infections respectively .

它最初是在猴体内发现的，由于它被误诊为良性的三日疟原虫，这类病例的数量被大量低估了（参见致命疟疾类型“被误诊为良性类型”）。

Originally identified in monkeys , the number of cases has been grossly underestimated due to its misdiagnosis as the benign P.malariae ( see Fatal malaria strain'mistaken for more benign form ' ) .

37例血样检测结果全部阳性，当原虫密度低至25个原虫/uL血时仍可成功检测到该特异条带，且其它三种人疟原虫（恶性疟原虫，三日疟原虫和卵形疟原虫）血样均为阴性。

Density of about 25 parasites per ul of blood can be detected successfully . None of other three human malaria species ( Plasmodium falciparum , Plasmodium malariae and Plasmodium ovale ) samples was positive .
