Highlights:
- This study looks at biofilm formation and Legionella spp. colonisation on new plumbing material over an 8-week period.
- L. pneumophila was the dominant Legionella spp. with culturable cell concentrations peaking at 3.1 × 104 MPN/cm2 after 4 weeks.
- Several Legionella species co-occurred and had distinct dynamics of biofilm colonisation.
- Vermamoeba vermiformis was the dominant protozoan identified.
- The results highlight that biofilm formation within new building plumbing materials is a dynamic process where pathogenic Legionella species can be part of the earliest colonisers.
