What is gram positive strain?
Gram-positive bacterium are those that are stained dark blue or violet by Gram Staining. This is in contrast to Gram-Negative Bacterium, which cannot retain the crystal violet stain, instead taking up the counter-stain and appearing red or pink.

Why good bacteria are important for your body?
Certain bacteria (the good bacteria) helps the body's immune system by fighting off the bad bacteria, and plays a major role in the digestive tract. That's one reason some people get diarrhea when taking antibiotics. The antibiotics kill the bad bacteria, but they also kill the good bacteria, as well. So for that reason, it's always a good idea to eat foods with active cultures, such as yogurt or buttermilk when taking antibiotics, because they replace the good bacteria back in the body. Actually, it's a good idea to eat foods with active cultures even when you're not taking antibiotics, because they will help your body's natural defenses against the bad bacteria.
