Researchers at the University of Silesia, Poland, have conducted a comparison study on the stools of children diagnosed with Autism vs. what is considered a "Typically Developing Child". The aim of the research was to identify whether elevations of fecal lactoferrin and a bacteria producing toxin, Clostridium species were more commonly found in children diagnosed with Autism. You may ask, why would such a study take place? There is both scientific and antecdotal evidence that Autistic behaviour is often accompanied by numerous symptoms such as abdominal pain, constipation, diarrhoea and imbalances in the natural flora of the digestive tract. These types of symptoms are often connected to elevated fecal lactoferrin and elevations in clostridium species. The results of the study showed that elevations of fecal lactoferrin were present in 66.4 percent of children diagnosed with Autism compared to 13 percent of Typically Developed Children. Moreover, 73.2 (37 out of 51 children in the study) percent of children diagnosed with Autism had elevations of clostridium species compared to 20 percent (only 2 of the 10 children in the study) of the children considered "typically developed".
