  • Your body contains a lot of white blood cells to help fight off pathogens entering your body. The first time your body detects a new pathogen, bacteria, or virus in your system your immune responses kick in (primary response) which is why you tend to suffer from a feverish state, but when your has body has developed that natural immunity w/in your system, you're less likely to get very sick the second time around or at all (secondary response).

  • When your immune system detects an 'intruder' (a bacteria, parasite, foreign body) it sets off the immune response. Your body begins pumping out white blood cells to kill/disable/eat the invading mechanism. All the extra work of making WBC's and then the extra work to get them out into the system cause internal body temp to rise. IIn adults the amount of temperature risen gives an idea about the amount of infection/response going onj. This is not true in ingfants and young children. Their immune systems are still forming and do not regulate themselves very well. That is why a baby can have an ear infection and spike a 103 right off the bat. An adult can have the same ear infection and run 100'

  • From the internet..........The cause of the fever is quite an intricate process. Our blood and lymphatic systems produce white blood cells which are what fight off infection. As our white blood cells increase in number, like an army to fight the germs, this causes our bodies to heat up, thus causing the fever or rise in body temperature. It is not good to try to bring down a fever too much or too fast. A temperature of 100 to 101 degrees Farenheit is good for the body because it shows that the body is fighting the infection. However, if a fever goes too high, measures must be taken to bring the fever down a bit.

  • so pathogens are seperate from bacteria and virus?

    Comment by AddyRF (original poster) at 4:56 PM on Sep. 28, 2010

  • Pathogen: An agent of disease. A disease producer. The term pathogen most commonly is used to refer to infectious organisms. These include bacteria (such as staph), viruses (such as HIV), and fungi (such as yeast). Less commonly, pathogen refers to a noninfectious agent of disease such as a chemical.

    The term pathogen was devised about 1880 and was compounded from patho- meaning disease + -gen indicating a producer. Hence, a disease producer.
