Concept explainers
To determine:
The optimum growth temperature for human pathogens.
Introduction:
Human pathogens are the microorganisms that are
responsible for causing disease in humans. They may enter the human body by puncturing
the mucosae or skin. A human pathogen may either invade internal organs or may
colonize the skin surface.
Explanation of Solution
Microorganisms are adapted to survive in a wide range of temperatures.
Temperature plays a crucial role in the
enzymes stop functioning, cell membrane distorts, and cellular integrity is
lost at temperatures higher or lower than the temperature range of a microorganism.
A pathogen capable of infecting humans can easily grow on the temperature range of the human body. The human body temperature is around 37°C. Therefore human pathogens also have optimum growth temperatures around 37°C.
The optimum growth temperature of human pathogens is 37°C.
