Titel: The effect of Established Biofilms on the Survival of Environmental E. coli

Kurzbeschreibung: The effect of Established Biofilms on the Survival of Environmental E. coli, P. aeruginosa and E. faecalis under Natural Swimming Pool Conditions

Zusammenfassung: Biological filter systems are an established technology in many forms of water treatment, however, in recent years these water filtration systems have become increasingly popular for use within natural bathing waters. Because natural bathing water systems undergo no chemical disinfection, concerns have been raised about the microbiological safety of the systems for end users, especially when maintenance is neglected (e.g. Giampaoli, S et al. 2014). This paper addresses the question “how capable are biological filters at mitigating intestinal pathogen contamination?”. The primary health concern regarding biological filters is the potential for pathogenic strains to colonise and proliferate within the biofilm and persistently shed into the water body (Nocker (2014). If pathogens were able to be incorporated into the filter biota, this has the potential to periodically increase pathogen levels to infectious levels. The experiment intended to examine if a biological filter is indeed a source of such an ‘infectious dose’.
