Now my husband has diharrea as well that is over 30 hrs long. We went to the hospital but the staff there don't seem to know what it is and/or not taking me seriously. They requested stool sample. Since this bacteria is part of the natural Intestinal flora wont the test show a false positive and/or would a blood test be more accurate? also how long does it take for the culture to develop om a slide? Ps; I live in canada
