一、间日瘧的复发反复复发是间日瘧的重要特点,复发的控制是瘧疾防治工作中的一个重要问题。要了解瘧疾复发的原因,首先要复习一下瘧原虫的生活史。当按蚊叮咬人体时,瘧原虫孢子体进入体内,首先在肝实质细胞中繁殖,然后才进入血液红细胞。恶性瘧原虫进入红细胞后,肝臓内的原虫即不再继续存在。间日瘧及三日瘧原虫进入红细胞后,肝臓内仍有原虫寄生,称持续性红细胞外期,它经过一定时期的繁殖,可不断向血内放出原虫。
First, repeated recurrent vivax malaria relapse is an important feature of vivax malaria, control of recurrence is an important issue in the prevention and treatment of malaria. To understand the causes of malaria relapse, we must first review the life history of Plasmodium. When Anopheles bite the human body, the Plasmodium sporozoites enter the body, first in the liver parenchyma cells, and then into the blood red blood cells. After the Plasmodium falciparum enters the erythrocytes, the protozoan within the liver pouch no longer exists. Plasmodium vivax and Plasmodium malaria into the red blood cells, there is still protozoan liver parasitic parasites, known as persistent extra-corpus erythrocytosis, which after a certain period of breeding, protracted release of protozoa to the blood.
