In terms of medicine. Thanks in advance.

the condition of being immune; the protection against infectious disease conferred either by the immune response generated by immunization or previous infection or by other nonimmunologic factors.
the natural ability of an organism to resist microorganisms or toxins produced in disease.Source(s): http://medical-dictionary.thefreedictionary.com/ http://www.searchoptima.com/immunity_and_resistanc...

immunity means that the person or bacteria cannot be affected by the external factor (bacteria or drug respectively). Resistance means that the same can be affected but at high doses as the bacteria or drug can be ineffective. If a person is immune to smallpox then he/she will not get smallpox even if the bacteria was introduced. If the bacteria was resistant against penicillin then penicillin may be only effective at high doses. The flu is the best example of drug resistant while a large number of people are immune against poison oak.

Immunity generally refers to a specific protection afforded by antibodies produced in response to an antigen. Sometimes it is a disesase, other times immunity is bestowed by a vaccination. Resistance is a more general term that refers to a person's overall health, nutritional status, etc.Source(s): I am an RN

Immunity is where you could never get sick from something where say other ppl were. Resistance is where you got sick like everybody else but with time your body got used to whatever was making you sick and your body can resist a certain sickness better with time.
Hope that's what you was looking for as a answer.

Organisms that have immunity have adequate biological defenses (i.e., antibodies, white blood cells,etc) to fight infection, disease, or other biological invasions. Therefore, they (the organisms) do not fall sick or ill to the pathogen. Resistance, on the other hand, is the result of a genetic mutation. Here, the organism can withstand pathogens (chemicals, pesticides, salt, wind, heavy metals, etc) because it has been genetically programmed to do so.

if you re immune, you develop immunity after exposure to disease. eg. get smallpox once, never again.
if you re resistant,the mutation occurred before selecting agent was introduced. eg. if a moth was non-resistant to pesticide got sprayed, it s dead, it pesticide doesn t cause it to develop a mutation.
basically, immunity only occurs after exposure, resistance was already there before exposure.

I would use your yahoo search engines under medical terms for both words.
