在种类繁多的原生动物中,有两属的种类寄生在脊椎动物的肌肉及其他器官,并能传染给人,即所谓人畜共患(或动物源性)寄生虫。最典型的是弓形体属(Toxoplasma)的刚地弓形体(T.gondii),血清学检查表明,人群感染该虫相当普遍;另一属就是目前人们仍不太熟悉的宿主特异性很高的肉孢子 Among a wide range of protozoa, two species of species are parasitic on the vertebrate muscles and other organs and can be transmitted to humans, the so-called zoonotic (or zoonotic) parasites. The most typical is the genus T.gondii of the genus Toxoplasma (T.gondii), serological examination showed that the crowd infected with the worm is quite common; the other genus is currently still not familiar with the host-specific high Meat spores
