Abstract

Salmonella -contaminated well water could cause major infection outbreaks worldwide, thus, it is crucial to understand their persistence in those waters. In this study, we investigated the persistence of Salmonella enterica serovar Typhimurium in 15 well waters from a rural area of Changchun City, China. Results illustrated that the time to reach detection limit ( ttd ), first decimal reduction time ( δ ), and the shape parameter ( p ) ranged from 15 to 80 days, from 5.6 to 66.9 days, and from 0.6 to 6.6, respectively. Principal component analysis showed that ttd s of S. Typhimurium were positively correlated with total organic carbon, pH, NH 4 + –N, and total phosphate. Multiple stepwise regression analysis revealed that ttd s could be best predicted by NH 4 + –N and pH. Canonical correspondence analysis and variation partition analysis revealed that NH 4 + –N and pH, and the rest of the water parameters, could explain 27.60% and 28.15% of overall variation of the survival behavior, respectively. In addition, ttd s were found to be correlated ( p < 0.01) with δ and p . Our results showed that the longer survival (>2.5 months) S. Typhimurium could constitute an increased health risk to the local communities, and provided insights into the close linkage between well water quality and survival of S. Typhimurium .
