Document Summary
Table 4 list of benefits of fever; how it affects the immune system: components of the immune system that we know are useful in responding to pathogens, not enough to demonstrate adaptation, is this evidence sufficient to demonstrate that the febrile system was shaped/modified by natural selection to coordinate various components of the immune response, rate of chemical reactions increases with increased temperature it is possible that natural selection hasn"t shaped the febrile system to specifically do these things, they may be a byproduct. Temperature dependent phagocytosis of straphylococcus aureus by human leukocytes: enhancement of phagocytosis is specific to the febrile range, as temperature increases, the number of bacteria that a phagocyte can digest increases, doesn"t seem to be evidence of a simple temp dependent effect; it is specific to normal febrile range goes against alternative hypothesis that it is a byproduct, 38 c 42 c.
