C. cayetanensis reproduces through egg-like structures called oocysts that are shed in human stool.

环孢子虫通过称为卵的蛋状结构繁殖，这些卵随人类粪便排出。

These oocysts can then be picked up by birds, mice or people.

然后这些卵会进入鸟类，老鼠或者人类体内。

Backyard surveys have found up to 400 Toxo oocysts per square foot. They can survive for more than a year and a half in the soil.

对后院的调查发现，每平方英的土地上大约有400个弓形虫卵。能在土壤中存活一年半的时间。

If the mouse gets eaten by a cat, the tissue cysts become active and release offspring that mate to form new oocysts, completing the cycle.

如果老鼠被猫吃掉， 组织肿就会激活并释放后代， 这些后代会交配形成新的卵，从而完成生命周期。

The oocysts broke down and formed tachyzoites.

卵孢破裂后形成了速殖体(Tachyzoites)。

The offspring, called oocysts, are shed in the cat's feces.

这些后代被称为卵，随猫的粪便排出。

We can accidentally ingest oocysts in contaminated water or unwashed produce, or from playing in sandboxes or cleaning out litter boxes.

我可能会在饮用受污染的水或未清洗的农产品时， 意外摄入卵，也可能在玩沙箱或清理猫砂盆时接触到。

The oocysts traveled down DD's GI tract from his mouth, traversing the lining of his intestines.

卵孢从DD的嘴，顺著消化道到达了小肠。

We can also get toxo from eating undercooked meat from other animals that picked up some oocysts.

我还能通过食用未煮熟的其他动物肉类感染弓形虫，这些动物可能摄入了一些卵。
