The emerging concept of host specificity of Cryptosporidium spp. was exploited to characterize sources of fecal contamination in a watershed. A method of molecular forensic profiling of Cryptosporidium oocysts on microscope slides prepared from raw water samples processed by U.S. Environmental Protection Agency Method 1623 was developed. The method was based on a repetitive nested PCR-restriction fragment length polymorphism-DNA sequencing approach that permitted the resolution of multiple species/genotypes of Cryptosporidium in a single water sample.
隐孢子虫属宿主特异性这一新兴概念被用于确定流域粪便污染的来源。我们开发了一种分子法医分析方法,用于对经美国环境保护局方法1623处理的原水样本制备的显微镜载玻片上的隐孢子虫卵囊进行分析。该方法基于重复巢式PCR-限制性片段长度多态性- DNA测序方法,能够在单个水样中分辨出多种隐孢子虫的物种/基因型。
