Methodological approaches for monitoring opportunistic pathogens in premise plumbing: A review [PDF]

open access: yesWater Research, 2017
Opportunistic premise (i.e., building) plumbing pathogens (OPPPs, e.g., Legionella pneumophila, Mycobacterium avium complex, Pseudomonas aeruginosa, Acanthamoeba, and Naegleria fowleri) are a significant and growing source of disease. Because OPPPs establish and grow as part of the native drinking water microbiota, they do not correspond to fecal ...

Dynamics of the Microbial Community and Opportunistic Pathogens after Water Stagnation in the Premise Plumbing of a Building

open access: yesMicrobes and Environments, 2022
In premise plumbing, microbial water quality may deteriorate under certain conditions, such as stagnation. Stagnation results in a loss of disinfectant residual, which may lead to the regrowth of microorganisms, including opportunistic pathogens. In the present study, microbial regrowth was investigated at eight faucets in a building over four seasons ...

Molecular detection of opportunistic premise plumbing pathogens in rural Louisiana's drinking water distribution system

Environmental Research, 2020
Opportunistic premise plumbing pathogens (OPPPs) in drinking water distribution systems are responsible for causing numerous infections such as Legionnaires' disease and pneumonia through the consumption of contaminated drinking water. The incidence of opportunistic pathogens and the number of individuals at risk of contracting infections caused by ...

Plumbing of hospital premises is a reservoir for opportunistically pathogenic microorganisms: a review

Biofouling, 2013
Several bacterial species that are natural inhabitants of potable water distribution system biofilms are opportunistic pathogens important to sensitive patients in healthcare facilities. Waterborne healthcare-associated infections (HAI) may occur during the many uses of potable water in the healthcare environment.

One-year survey of opportunistic premise plumbing pathogens and free-living amoebae in the tap-water of one northern city of China

Journal of Environmental Sciences, 2019
In this study, qPCR was used to quantify opportunistic premise plumbing pathogens (OPPPs) and free-living amoebae in 11 tap water samples collected over four seasons from a city in northern China. Results demonstrated that the average numbers of gene copies of Legionella spp. and Mycobacterium spp. were significantly higher than those of Aeromonas spp.

Impact of blending for direct potable reuse on premise plumbing microbial ecology and regrowth of opportunistic pathogens and antibiotic resistant bacteria

Water Research, 2019
Little is known about how introducing recycled water intended for direct potable reuse (DPR) into distribution systems and premise plumbing will affect water quality at the point of use, particularly with respect to effects on microbial communities and regrowth.

Opportunistic premise plumbing pathogens: a new challenge in the hospital

2020
In the last few years much attention has been paid to a group of environmental microorganisms whose source is water from the distribution system in residential buildings and health facilities. The name of these group of bacteria is Oportunistic Premise Plumbing Pathogens (OPPP).

Spatio-temporal survey of opportunistic premise plumbing pathogens in the Paris drinking water distribution system

International Journal of Hygiene and Environmental Health, 2019
Opportunistic premise plumbing pathogens present in drinking water are linked to a significant number of infections for health compromised patients. However, their monitoring is not required in current water potability standards and they have been poorly studied in a full-scale network.
