It was clearly
demonstrated that rotifers of six genera can swallow oocysts of Cryptosporidium
parvum. The oocysts were labeled with fluorescent antibodies. Three
microscopical techniques: phase contrast, differential interference contrast and fluorescence microscopy were used which
complemented each other. The presence of the oocysts was unambiguously revealed
in the stomachs of all six rotifer genera and in two of them subsequent
excretion of clumps of the oocysts along with some other material was observed.
The authors could not manage to determine if the excreted oocysts were nonviable or at least inactivated. Yet
they believe that even if the oocysts remained active and infectious the size
of the clumps would facilitate to remove those from water.
