![]() ![]() pneumophila rapidly colonizes present biofilm communities (Murga et al., 2001 Vervaeren et al., 2006 Declerck et al., 2007). “Using a more realistic experimental set-up, consisting of multispecies biofilms formed under oligotrophic conditions, it has been demonstrated that L. ![]() Priscilla Declerck’s article, Biofilms: the environmental playground of Legionella pneumophila (Society for Applied Microbiology and Blackwell Publishing Ltd, Environmental Microbiology, 12, 557-566) summarizes several research studies involved with the mechanisms and factors that affect the biofilm life cycle of L. Legionella pneumophila resides primarily in biofilms in building and industrial water systems. Thus, preventing biofilm formation appears as one of the strategies to reduce water system contamination.” (emphasis added) The evidence from decades of scientific research is very clear. There is now evidence that some legionellosis outbreaks are correlated with the presence of biofilms. pneumophilareplicates within environmental protozoa, colonization and persistence in its natural environment are also mediated by biofilm formation and colonization within multispecies microbial communities. The importance of biofilm control is highlighted in the following excerpt from Biofilms: The Stronghold of Legionella Pneumophila by M. Legionella bacteria grow in biofilms in building water systems, where they are protected from the disinfecting action of oxidizing and non-oxidizing biocides. Outbreaks in Legionnaires’ Disease such as the one in the South Bronx in August 2015 highlights the importance of having an effective Legionella Control Program. ![]()
