Has anybody ever heard of a stool culture for E coli being divided into: -Adherence -Enteroinvasive -Labile Toxin -Verotoxin I had a 10 month old who's diarrhea finally resolved after about 10 days, but a few days later the culture I'd sent off the previous week came back positive for E coli - Adherence, negative for the other three categories. The local GI consultant had never heard of a culture being reported this way. Any input would be greatly appreciated. Michael Sachs, M.D. General Pediatrician
