Abstract
Cryptosporidium parvum oocysts accumulate on biofilm surfaces. The percentage of oocysts attached to biofilms remained nearly constant while oocysts were supplied to the system but decreased to a new steady-state level once oocysts were removed from the feed. More oocysts attached to summer biofilm cultures than winter biofilm cultures.
摘要
微小隐孢子虫卵囊积聚在生物膜表面。当向系统供应卵囊时，附着在生物膜上的卵囊百分比几乎保持不变，但一旦从进料中去除卵囊，该百分比就会降至新的稳态水平。附着在夏季生物膜培养物上的卵囊比冬季生物膜培养物上的更多。
