The body temperature is 37º C, which is best operating temperatures for mesophiles.
Pathogens and other mesophilic bacteria.
Most pathogens are mesophilic because they thrive inside of the human body. Mesophilic pathogens grow at an optimum temperature of 35-37 degrees Celsius, which is the normal human body temperature.
Yes, bacterial infections by mesophilic pathogens can cause the symptom of a sore throat. For example, one infamous bacteria for this is Streptococcus pyogenes which causes strep throat.
E.coli, Salmonella, Klebsiella, Staphylococcus
the skin keeps out most pathogens
Thermophilic enzymes are stable (they grow and thrive) at temperatures between 60-80 degrees Celsius. This makes them easier to study. This is because mesophilic enzymes will denature at these temperatures, and unlike mesophilic enzymes, thermophilic enzymes will not denature at room temp (25 degrees Celsius, making it easier for scientist to work with thermophilic enzymes. In other words, in biotechnology thermoenzymes have thermo stablity that mesophilic enzymes do not, making them much better use under certain conditions ( where mesophilic enzymes would denature).
Viruses are the most powerful pathogens...

No, most pathogens do not pass through mucous membranes easily. Mucous membranes act as a barrier to protect the body from pathogens by trapping them and preventing them from entering the body. However, some pathogens have evolved mechanisms to breach this barrier and cause infections.
In most circumstance, illness.
Most pathogens grow well at 37 degrees Celsius because this is the normal body temperature of mammals, including humans. This temperature provides an ideal environment for pathogens to thrive and replicate within the host's body.
Astrocytes are most responsible for preventing pathogens and toxins from entering the brain through blood.
