The 1976 outbreak of Legionnaires' disease led to the discovery of the intracellular bacterial
pathogen Legionella pneumophila. Given their impact on human health, Legionella species …

Opportunistic premise (ie, building) plumbing pathogens (OPPPs, eg, Legionella
pneumophila, Mycobacterium avium complex, Pseudomonas aeruginosa, Acanthamoeba …

Amoebae are widespread in water and serve as environment vectors for pathogens, which
may threaten public health. This study evaluated the inactivation of amoeba spores and their …

Biofilms are comprised of microorganisms embedded in a self-produced matrix that normally
adhere to a surface. In the food processing environment they are suggested to be a source …

Biofilms in drinking water distribution systems (DWDS) could exacerbate the persistence
and associated risks of pathogenic Legionella pneumophila (L. pneumophila), thus raising …

Secondary water supply systems (SWSSs) are characterized by long water stagnation and
low levels of chlorine residuals, which may pose a high microbial risk to terminal users. In …

Drinking water distribution systems (DWDS) may be a “Trojan Horse” for some waterborne
diseases caused by opportunistic pathogens (OPs). In this study, two simulated DWDS …

Secondary water supply systems (SWSSs) refer to the in-building infrastructures (eg, water
storage tanks) used to supply water pressure beyond the main distribution systems. The …

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 …

Opportunistic pathogens (OPs) are emerging microbial contaminants in engineered water
systems, yet their growth potential in rainwater systems has not been evaluated. The …
