Relationship between Legionella pneumophila gene copy number and Vermamoeba vermiformis gene copy number. Samples included for analysis were (1) distal tap samples with (2) water heater temperature set point at 40 °C and (3) collected at 2-month pre-, immediately pre-, and 2-month post-heat shock, who had (4) quantifiable L. pneumophila and V. vermiformis numbers by qPCR. Both gene copy numbers were log-transformed with base 10
