The temperature of a human body is anywhere from 35-40C. What type of pathogen can infect humans?
A
Thermophile.
B
Hyperthermophile.
C
Psychrophile.
D
Mesophile.
Verified step by step guidance1
Understand the temperature range of the human body, which is typically between 35°C and 40°C.
Identify the temperature range preferences of different types of microorganisms: Thermophiles prefer temperatures between 45°C and 80°C, Hyperthermophiles thrive above 80°C, and Psychrophiles prefer cold environments, typically below 15°C.
Recognize that Mesophiles are microorganisms that thrive at moderate temperatures, typically between 20°C and 45°C, which includes the human body temperature range.
Consider the fact that most human pathogens are mesophiles because they are adapted to grow at the temperature of the human body.
Conclude that the type of pathogen that can infect humans, given the body temperature range, is a Mesophile.
