Quick test shows gut flora in piglets

When piglets are weaned from milk to solid food, their intestinal flora change, with a steep rise in the numbers of potentially harmful streptococci. This finding has come out of research done by Odette Pérez Gutiérrez, who developed a micro-array called the PIT (pig intestinal tract) chip with which she can quickly scan six hundred different types of bacteria on a glass slide in the lab.
