title: Retention and release of Cryptosporidium parvum oocysts by experimental biofilms composed of a natural stream microbial community.
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.
