Free-living amoebae have been detected in a large number of man-made water systems, including drinking water distribution systems. Some of these amoebae can host amoebae-resisting bacteria, and thus act potentially as reservoirs and vehicles for a number of pathogens. The objectives of this study were to characterize the amoebae and amoebae-resisting bacteria present in different raw waters used for drinking water production, and to assess the efficiency of different treatments applied for drinking water production in removing or inactivating these amoebae. The preliminary results of this study confirm the presence of amoebae and amoebae-resisting bacteria in raw waters used for drinking water production. Due to their capacity to encyst, most of these amoebae are extremely resistant to disinfection processes. In these conditions, preventing the dissemination of these micro-organisms through drinking water will mainly require their physical removal by clarification and filtration processes. The particular hazard that amoebae-resisting bacteria represent in drinking water production should be taken into account in any risk assessment conducted in the framework of a water safety plan, and control strategies based on physical removal rather than disinfection should be adopted where necessary.

Controlling microbial contamination of drinking water is critical to public health. However, understanding of the microbial ecology of drinking water remains incomplete. Representing the first application of high-throughput sequencing in drinking water microbiology, the objective of this study is to evaluate pyrosequencing as a high-throughput technique for the characterization of bacterial diversity in drinking water in comparison with conventional clone library analysis. Pyrosequencing and clone library analysis were performed in parallel to study the bacterial community composition in drinking water samples following the concentration of microbial biomass in drinking water with ultrafiltration. Validated by clone library analysis, pyrosequencing was confirmed as a highly efficient deep-sequencing technique to characterize the bacterial diversity in drinking water. Sequences of Alphaproteobacteria and Betaproteobacteria dominated the bacterial community in drinking water with Oxalobacteraceae and Methylobacteriaceae as the most abundant bacterial families, which is consistent with the prominent abundance of these populations frequently detected in various freshwater environments where source waters originate. Bacterial populations represented by the most abundant sequences in drinking water were closely related to cultures of metabolically versatile bacterial taxa widely distributed in the environment, suggesting a potential link between environmental distribution, metabolic characteristics, and abundance in drinking water.
