Filtration abilities of Cryptosporidium parvum oocysts by rotifers (Brachionus calyciflorus) were studied. The filtration rate of rotifers is quick: the passage of oocysts through the digestive system is few minutes only. During the first 10 minutes 24300 of whole amount one million oocysts passed through the digestive system of 100 rotifers. Moreover, 93% of oocysts were death after passage. All oocysts expelled were unable to infect suckling BALB/c mice. Oocysts were degraded in mastax, stomach and intestine. Rotifers can be use for detection of cryptosporidia oocysts in water and they effectively decrease their numbers.
