Impact of Flow Rate and Water Age on Opportunistic Pathogen Growth: Implications for Water Conservation, Fixture Design, and Policy
… cold-water influent levels at 7.5 days WRT. Legionella spp. and Mycobacterium spp. demonstrated opposite responses to flow rate with chloramine minimization. The highest levels of Legionella spp. (1.7 log higher than influent) were present when flow velocity was >2 feet per second (fps), but …

A comparison of flow cytometry and conventional microbiology in the study of biofilms.
… the results of flow cytometric analysis of total Legionella pneumophila cells have a strong statistical correlation with the numbers of Legionella cfu by BCYE plate counting (BCYE PC) methods for biofilms and planktonic phases. There are also strong statistical correlations between flow cytometric …
