The non-pathogenic micro-organisms are considered to be normal flora. These grow in places like the throat and nose. They are 'expected' organisms and are not life threatening to most individuals.
Pathogenic micro-organisms are abnormal flora. In the above mentioned example, a throat culture that grows strep would be pathogenic and the doctor might therefore diagnose strep throat. It does not usually grow in that place.
Not all pathogenic organisms lead to life threatening conditions; however if a person's immune system is compromised even normal flora can be difficult to overcome.
Pathogenic means it is causative for a disease and non-pathogenic means it is harmless....eg: influenza is pathogenic.
pathogenenic microorganisms cause disease. Non-pathogenenic, not.
a pathogen can kill you or cause disease, a non-pathogen won't
A pathogen is an organism that causes disease (they are PATHOlogy GENerators). A pathogen that does not cause disease is an oxymoron.
It depends, pathogens can be multicellular (cestoda, fungi), unicellular (bacteria) or they can have non-cellular build (viruses, prions).
Specific immunity follows a non-specific response. The major difference between specific and non-specific is the ability to remember pathogenic antigens. Specific immunity results in the production of memory cells which upon reinfection are used to effectivly remove the pathogen Non-specific cannot do this
