FIG 1.
V. cholerae concentrations in 2011 as determined by qPCR, cultivation, and CARD-FISH/SPC. (A) Sampling site 5, Neusiedler See; (B) sampling site 36, Neusiedler See; (C) sampling site ZL (soda pool Zicklacke). qPCR-based concentrations are given without correction (blue bars) and with correction (corrected with global recovery rate; red bars). Cultivation-based (green bars) and CARD-FISH/SPC (purple bars) results are shown. A black dotted line indicates the water temperature. A missing bar means that an analysis with the respective method was not possible; bars between 0 and 1 indicate V. cholerae concentrations below the detection limit. Values and error bars represent the mean of three (cultivation, qPCR) and three to eight (SPC/CARD-FISH) replicates ± standard deviation. GU, genomic units.
