“…Despite this, the interaction between them is often the factor that enhances or decreases the inactivation rate, for example, predation is enhanced by temperature (Barcina et al 1997;Hipsey et al 2008) and sunlight increases oxygen reactive species in the presence of organic matter, thereby reinforcing inactivation (Maraccini et al 2012;Appiani and McNeill 2015). Microcosms/mesocosms in laboratory conditions that focus on single factors have therefore been found to differ from on-site experiments (Balleste and Blanch 2010;Green et al 2011;Bae and Wuertz 2015;He et al 2015). In this study, an on-site approach was used in order to assess and compare the inactivation rates of certain FIB (EC and ENT) from different sources (human, porcine, bovine and poultry) and detect potential differences between them.…”

The diverse inactivation rates observed in bacteria from different faecal sources have implications when these rates are used to model faecal pollution in water. The use of FIBT of different sources is essential to develop reliable predictive models. Since different inactivation of E. coli regarding the source of pollution has been observed, the source of the pollution has to be considered for modelling approaches.

“…Thirdly, high abundance means a long half-life, and potential for persistence in environmental compartments. Several groups have reported mtDNA from human and dog feces can persist in water for 15–29 days (Martellini et al 2005; Tambalo et al 2012), and mtDNA markers can survive for relatively long time in water bodies (He et al 2015). Finally, the mtDNA of most common species have been fully sequenced and are freely available.…”

Poultry are an important source of fecal contamination in environments. However, tools for detecting and tracking this fecal contamination are in the early stages of development. In practice, we have found that source tracking methods targeting the 16S rRNA genes of poultry-specific microbiota are not sufficiently sensitive. We therefore developed two quantitative PCR assays for detection of poultry fecal contamination, by targeting chicken and duck mitochondrial genes: NADH dehydrogenase subunit 5 (ND5) and cytochrome b (cytb). The sensitivity of both assays was 100% when tested on 50 chicken and duck fecal samples from 10 provinces of China. These assays were also tested in field samples, including soil and water collected adjacent to duck farms, and soils fertilized with chicken manure. Poultry mitochondrial DNA was detected in most of these samples, indicating that the assays are a robust method for monitoring environmental contamination with poultry feces. Complemented with existing indicators of fecal contamination, these markers should improve the efficiency and accuracy of microbial source tracking.
