Bacteria that are able to grow in humans and cause disease would be classified as Bacteria that are able to grow in humans and cause disease would be classified as __________.a. mesophiles. b. thermophiles. c. psychrophiles. d. hyperthermophiles.

Mesophiles are the population of bacteria that can grow under moderate conditions of temperature, that is, from 20°Celsius to 40°Celsius.
The normal temperature of human body is 37°Celsius.
The bacteria which survive in humans and cause disease must be such that they are capable of growing optimally in the 37°Celsius temperature range.
The bacteria which grow in this range are the Mesophiles.
Thermophiles are those bacteria that can thrive in very high temperature conditions of 50°Celsius to 120°Celsius.
Psychrophiles are those bacteria that can thrive in very low temperature conditions of -20°Celsius to 10°Celsius.
Hyperthermophiles are those bacteria that can thrive in extremely high temperature from 60°Celsius to more than 130°Celsius.
