隱孢子蟲屬
隱孢子蟲屬(學名:Cryptosporidium)是頂複門的一個屬,本屬部分物種可感染包括人類在內的許多脊椎動物,造成隱孢子蟲病,症狀包括腹瀉與咳嗽等[1]。

感染
隱孢子蟲與瘧原蟲和弓形蟲皆為頂複門的寄生蟲,有別於後兩者,隱孢子蟲的生活史中不需中間宿主[2]。隱孢子蟲病多為短期、急性的疾病,感染後隱孢子蟲可生存在人類的腸道長達五週,造成腹瀉等症狀[1]。在體外隱孢子蟲以卵囊的形式存在,對環境的抗性很高,進入人體後即可感染小腸上皮組織。造成人類隱孢子蟲病的物種大多是小隱孢子蟲與人隱胞子蟲兩種,不過犬隱孢子蟲(C. canis)、貓隱孢子蟲(C. felis)、火雞隱胞子蟲(C. meleagridis)與鼠隱孢子蟲也可能感染人類[2]。免疫缺陷者被感染的症狀一般較嚴重,但免疫正常者也可能被感染[2]。
