"Here, we compared SourceTracker and Fast Expectation-Maximization Microbial Source Tracking data on environmental water bodies exposed to low fecal pollution and determined treatment effects of fecal pollution in the watershed using community-based MST. " Our results revealed that FEAST overall outperform SourceTracker in terms of accuracy and stability, and was able to distinguish multi-source fecal contamination in ambient water bodies exposed to low fecal inputs.

"The aim of this research was to determine the specificity and abundance of the human-specific MST marker crAssphage with PCR and RT-PCR assays in human and animal feces in Korea. " In 94 human feces samples and 56 animal feces samples, crAssphage was found. In human feces, crAssphage is sufficiently abundant in human feces, according to a quantitative analysis, given the high frequency range of 4. 26 to 8. 25 log gene copies /ng. "In conclusion, this review established the crAssphage as a specific and abundant MST marker by which to determine human fecal contamination in Korea. ".
