Human-Associated Bacteroides spp. and Human Polyomaviruses as Microbial Source Tracking Markers in Hawaii

Abstract: Identification of sources of fecal contaminants is needed to (i) determine the health risk associated with recreational water use and (ii) implement appropriate management practices to mitigate this risk and protect the environment. This study evaluated human-associated Bacteroides spp. (HF183TaqMan) and human polyomavirus (HPyV) markers for host sensitivity and specificity using human and animal fecal samples collected in Hawaii. The decay rates of those markers and indicator bacteria were identified in marin… Show more

“…Enterococci values for the covered condition in the current study were smaller than five out of the six inactivation rate constants from previous studies in the absence of sunlight ( Fig. 4 ) (ranging from −0.130 to −2.4 d −1 ) ( Ahmed et al., 2014 ; Anderson et al., 2005 ; Craig et al., 2019 ; Eichmiller et al., 2014 ; Jeanneau et al., 2012 ; Kirs et al., 2016 ). HF183/BacR287 values in the uncovered mesocosm were smaller than all 16 literature value inactivation rate constants whereas in the covered mesocosm, mean values were smaller than seven out of the nine literature value inactivation rate constants ( Fig.…”

“…Somatic coliphage, AdV and HPyV had values that were slightly smaller (not significant) than the mean value from the literature review ( Fig. 4 ) ( Ahmed et al., 2014 , 2019 ; Bae and Wuertz, 2015 ; Balleste et al., 2019 ; Chendorain et al., 1998 ; Craig et al., 2019 ; Elmahdy et al., 2018 ; Ibrahim et al., 2019 ; Kirs et al., 2016 ; Prevost et al., 2016 ; Wu et al., 2016 ).…”

“…However, comparing Bacteroidales host genetic markers illustrated that humanspecific markers were less stable than ruminant markers. In another study conducted by Kirs et al (2016), Bacteroidales spp. (HF183 TaqMan) markers as the indicators were used to determine sewage contamination in Hawaii.…”

“…Nonspecific (found in nontarget hosts) and nonprevalent (rare) markers tend to yield false-positive or -negative results in field studies (18). Several studies have determined the host prevalence and specificity of the HF183 (19), EC H8 (14), nifH (20), HAdV (21), HPyV (22), and PMMoV (17) markers by analyzing fecal and wastewater samples from various animals. The high host prevalence and specificity values of the aforementioned markers support their potential for human fecal pollution tracking.…”
