Characterising the drinking water microbiome on campgrounds in New Zealand

Abstract

Whole-genome, 16S and 18S ribosomal RNA (rRNA) analyses combined with conventional isolation techniques are being applied to profile microbial community DNA associated with drinking water on campgrounds. The current study has a serial cross-sectional design and is being conducted on 15 campgrounds that are situated across New Zealand (Figure 1) and are managed by the Department of Conservation (DOC). Preliminary results generally show low Escherichia coli counts in water, suggesting minimal faecal contamination, and a low proportion of faecal samples were positive for Campylobacter and Giardia.
