A novel filter system comprising open cell reticulated foam rings compressed between retaining plates and fitted into a filtration housing was evaluated for the recovery of oocysts of Cryptosporidium from water. Mean recoveries of 90.2% from seeded small and large volume (100-2000 l) tap water samples, and 88.8% from 10-20 l river water samples, were achieved. Following a simple potassium citrate flotation concentrate clean-up procedure, mean recoveries were 56.7% for the tap water samples and 60.9% for river water samples. This represents a marked improvement in capture and recovery of Cryptosporidium oocysts from water compared with conventional polypropylene wound cartridge filters and membrane filters.
评估了一种新型过滤系统，该系统由压缩在固定板之间并安装在过滤外壳中的开孔网状泡沫环组成，用于从水中回收隐孢子虫卵囊。从小体积和大体积（100 - 2000升）的接种自来水样本中平均回收率为90.2%，从10 - 20升河水样本中平均回收率为88.8%。经过简单的柠檬酸钾浮选浓缩净化程序后，自来水样本的平均回收率为56.7%，河水样本为60.9%。与传统的聚丙烯缠绕滤芯过滤器和膜过滤器相比，这在从水中捕获和回收隐孢子虫卵囊方面有显著改进。
