Thanks for explaining that in terms that I can remember *and* understand!Red and blue bacteria both in a slide are gram neg and gram positive. Blue are gram positive. Red are gram negative. In the poop, it is likely normal to see both.
If there is 100% of one or the other, usually that means that one organism has taken over. (infection), but without the culture you can not be sure which one. Some antibiotics work better for gram negatives and some for gram positives. Gram stains are usually done to give a really quick preliminary result while waiting for a culture to grow.
I am a generalist not a microbiology specialist. I may be able to get one of my co-workers to do a culture if we can sneak it in.![]()
