The objective of this work was to assess the effect of dilute bovine manure (1.0% and 0.1%) versus that of no manure on attachment and subsequent detachment of Cryptosporidium parvum oocysts to soil. Manure enhanced the attachment of oocysts to soil particles; the maximum attachment was observed with 0.1% manure. Oocyst attachment was partially reversible; maximum detachment was observed with dilute manure. These results indicate that oocyst attachment to soil is substantially affected by bovine manure in a complex manner and should have implications for how oocysts may be transported through or over soils.
这项工作的目的是评估稀释的牛粪（1.0%和0.1%）与不施牛粪相比，对微小隐孢子虫卵囊附着于土壤及随后从土壤中脱离的影响。牛粪增强了卵囊与土壤颗粒的附着；在施用0.1%牛粪时观察到最大附着量。卵囊的附着部分是可逆的；在稀释牛粪处理下观察到最大脱离量。这些结果表明，牛粪以复杂的方式对卵囊与土壤的附着产生显著影响，并且这可能对卵囊在土壤中或通过土壤的传播方式具有重要意义。
