What tool would you use to look at bacteria from your teeth?

You would use a microscope to look at bacteria from your teeth. A light microscope is commonly used for this purpose, as it can magnify the bacteria to a level where they can be observed and studied in detail.


How do scientists study how bacteria are affected by antibiotics?

Laboratory scientists culture a bacterium (one single bacteria) so the bacteria grows to a colony. Scientists create many specimens of colonies for each bacteria. Then they can expose each colony to a different antibiotic medication or new antibiotic to see how the bacteria react to it. They look for sensitivity--meaning, any reaction in the growth of the bacterial colony. The growth may have no change (no sensitivity), slow down, or stop. But even better, ingredients in antibiotics need to disrupt the way bacteria use nutrients, so scientists look to see if the bacteria die when exposed to that specific antibiotic.Different groups or families of antibiotics work best on certain bacteria. At the same time, certain bacteria favor conditions only in certain areas of the body. So the bacteria for a skin infection is different from the bacteria that infects the urinary tract, for example.
