na kad ne, dar patikslinimas (galiuno wikipedijos):
According to the paper "Legionella and the prevention of legionellosis,"[18] found at the World Health Organization website, temperature affects the survival of Legionella as follows:
Above 70 °C (158 °F) - Legionella dies almost instantly
At 60 °C (140 °F) - 90% die in 2 minutes (Decimal reduction time (D) = 2)
At 50 °C (122 °F) - 90% die in 80124 minutes, depending on strain (Decimal reduction time (D) = 80-124)
48 to 50 °C (118 to 122 °F) - Can survive but do not multiply
32 to 42 °C (90 to 108 °F) - Ideal growth range
25 to 45 °C (77 to 113 °F) - Growth range
Below 20 °C (68 °F) - Can survive but are dormant, even below freezing
Other sources[19][20][21] claim alternate temperature ranges:
60 to 70 °C (140 to 158 °F) to 80 °C (176 °F) - Disinfection range
66 °C (151 °F) - Legionella die within 2 minutes
60 °C (140 °F) - Legionella die within 32 minutes
55 °C (131 °F) - Legionella die within 5 to 6 hours
20 °C (68 °F) to 45 °C (113 °F) - Legionella multiply
20 °C (68 °F) & below - Legionella are dormant
