1st pt 7VM


the multiplication of organisms in a tissues of a host is called infection
indigenous micro flora are microbes that live on the skin or in the body
the relationship between human hosts and indigenous flora is called symbiosis
both organisms benefit from and depend on one another to certain extent is called mutualism
an example of mutualism is e coli- live in the intestine we feed it. they give us vit-k
a subcategory of mutualism- synergism
example of _________is fusobacteria and spirochetes wk together to cause trench mouth synergism
one organism benefits but the second organism neither benefits nor is harmed is called commensalism
subcategory of commensalism is called neutralism
two organisms occupy the same area with no effect on each other is called neuralism
one microorganism inhibits or interferes with the growth of another is called antagonism
a microbe produces waste products that are toxic to the neighboring microbes is called antagonism
one organism benefits and the is harmed is called parasitim
