The cartridge filtration method and membrane filtration method based on the fluorescent antibody procedure were evaluated for their recovery efficiencies and detection limits of Giardia and Cryptosporidium. We assessed the performances of the two concentration methods for water samples collected from Taiwan water treatment plants. The membrane filtration method was characterized by higher recovery rate and detection limit comparing with the cartridge filtration method. The occurrences of both parasites, and the relationships of parasite concentrations with indicator microorganisms show inconsistency between the two methods. It was discovered that water turbidity reduced the recovery efficiencies, and raised the detection limits for both parasites regardless of the method used.
基于荧光抗体程序的筒式过滤法和膜过滤法，针对贾第虫和隐孢子虫的回收效率和检测限进行了评估。我们评估了这两种浓缩方法对从台湾水处理厂采集的水样的性能。与筒式过滤法相比，膜过滤法的特点是回收率更高，检测限更低。两种寄生虫的出现情况，以及寄生虫浓度与指示微生物之间的关系，在两种方法之间存在不一致。结果发现，无论使用何种方法，水的浊度都会降低两种寄生虫的回收效率，并提高其检测限。
