State of the Science and Research Needs for Opportunistic Pathogens in Premise Plumbing

Abstract

This report presents information on the state of the science and research needs for opportunistic pathogens in premise plumbing (OPPPs) based on a WaterRF Expert Workshop. The report focuses on five model OPPPs: Legionella pneumophila, Mycobacterium avium Complex (MAC), Pseudomonas aeruginosa, Acanthamoeba spp., and Naegleria fowleri. Current understanding of their epidemiology, microbial ecology, methodology, and engineering controls are discussed. Published in 2013.
