Molluscan shellfish can recover and concentrate environmentally derived waterborne pathogens and can be used for the sanitary assessment of water quality. Oocysts of Cryptosporidium parvum (genotype 1) were identified in zebra mussels (Dreissena polymorpha) from the St. Lawrence River, Quebec. Approximately 67 oocysts/ml of hemolymph and 129 oocysts/g of soft tissue were recovered. The adjusted concentration of oocysts per gram of tissue was 2.2 x 10(2), and approximately 4.4 x 10(2) oocysts were recovered from a single mussel. Zebra mussels can serve as biological indicators of waterborne contamination with Cryptosporidium.
软体贝类能够摄取并富集环境中的水源性病原体，可用于水质的卫生学评估。在魁北克圣劳伦斯河的斑马贻贝（多形饰贝）中鉴定出了微小隐孢子虫（基因型1）的卵囊。每毫升血淋巴中约检出67个卵囊，每克软组织中约检出129个卵囊。每克组织中卵囊的校正浓度为2.2×10²，从单个贻贝中回收的卵囊约为4.4×10²个。斑马贻贝可作为水源性隐孢子虫污染的生物指标。
