英国一家公司研制出电转动分析法(Electrorotation Assay)。这种方法能够检测水中有无隐孢子虫与贾第鞭毛虫孢囊,方法和实质是采用抗体把目标微生物连接到细微镜。当电磁场旋转时,连接的微物生随着转动,在细微镜下可使它们与其它的生物体区别开。据称使用这种方法的费用、分析时间和性能均比目前使用的其它方法优越。在历史上,美国因水中的隐孢子虫引发病症的事例多起,其中最大一次是1993年发生在 A British company developed the Electro-Rotation Assay. This method allows detection of Cryptosporidium parvum and Giardia cysts in water by using antibodies to attach the target microorganisms to the micromirrors. As the electromagnetic field rotates, the connected micro-organisms turn as they move, allowing them to be distinguished from other organisms under the microscope. It is claimed that the cost, time and performance of this method are superior to other methods currently used. Historically, there have been more cases of illness caused by Cryptosporidium in the United States, the largest of which occurred in 1993 in
