根据寄生虫对标准药物疗程的临床反应,恶性疟原虫的氯喹抗性按惯例分为RⅠ、RⅡ和RⅢ型。RⅠ型猪的是寄生虫在氯喹治疗后暂时从血中清除,几天后又再现。这种现象通常被认为是原先的疟原虫中有氯喹抗性部分的再燃,但也可能是由于新的疟原虫的再感染所致。在苏丹东部地区确诊的恶性疟患者中,作者发现6例经氯喹标准剂量 According to the clinical response of the parasite to the standard drug regimen, the chloroquine resistance of P. falciparum is conventionally divided into R I, R II and R III.
