BIOLOGY QUESTION! Bacteria develop resistence to particular antibotics.

Explain the implications of this in the management of disease :)

its a biology question and i cant put my finger on it :( please help me

bec of survival of the fittest/natural selection some bacteria will develop resistance 2 antibiotics...
the antibiotics kill out the weak bacteria but the resistant survive 2 reproduce a generaiton more resistant 2 antibiotics....

Then you have less options of antibiotics to cure certain diseases, and eventually the disease will be resistant to all antibiotics, and therefore will run amuck and we can't cure it.
