疟疾是疟原虫所引起的传染病,由按蚊传播。按蚊叮咬疟疾病人时,把病人血液里的疟原虫的雌雄配子体一同吸到蚊胃里。雌雄配子体在蚊胃内交配受精成为合子→动合子。动合子穿过胃壁在弹性纤维膜下发育成为囊合子→孢子囊,内含成千上万个子孢子。子孢子从孢子囊逸出经过体腔大部分进入蚊唾液腺内,当蚊子叮咬人时,子孢子随按蚊唾液侵入人体而感染。 Malaria is an infectious disease caused by malaria parasites, transmitted by Anopheles mosquitoes. When anopheline bite malaria patients, the male and female gametophytes in the bloodstream of the patient’s bloodstream are attracted to the mosquito’s stomach. Female and male gametophytes in the mosquito stomach mating and fertilization into a zygote → moving zygotes. Zygotes through the stomach wall under the elastic fiber membrane to develop into zygapok → sporangia, contains tens of thousands of sporozoites. Sporozoites escaping from the sporangia most of the body cavity into the mosquito salivary glands, when the mosquito bites, sporozoites with anopheles saliva invade the body and infection.
