Legionella - Isolation Rates

Table 1
The top graph shows the breakdown of the positive Legionella results from 2000 to July 2006. The table is a stacked bar graph with the positive counts grouped into those from 10 to <100 CFU/mL, 100 to <1,000 CFU/mL and 1,000 or greater CFU/mL. This 100% stacked column compares the percentage each group contributed to the total of all positive Legionella isolates for that month.

 

The second graph shows the isolation rate of Legionella from 1993 to July 2006.

Table 2

This is derived from air-conditioning water samples. The lowest level of detection is 10 CFU/mL. The monthly figures are the percentage of samples that had a positive detection.

 

The bottom graph shows the breakdown of the plate count results from 2000 onwards.

Table 3

The table is a stacked bar graph with the positive counts grouped into those from <10,000 CFU/mL, 10,000 to <100,000 CFU/mL, 100,000 to <1 Million CFU/mL, 1Million to <5 Million CFU/mL and 5 Million or greater CFU/mL. This 100% stacked column compares the percentage each group contributed to the total plate count levels for that month.
