Final answer:
Pathogens grow fastest between temperatures of 41-135°F, and bacteria generally multiply most rapidly between 40 and 140 degrees F. Mesophiles, including many normal human microbiota and pathogens, have optimal growth temperatures ranging from room temperature (about 20°C) to about 45°C.
