SUMMARY: This study sequenced bacteria flora from the fecal samples of children with autism versus healthy controls. Results showed that there was a lower amount of Bifidobacteria species and higher levels of Lactobacillus species in the autistic children. There were higher amounts of short chain fatty acids (specifically butyrate and propionate).
LESSON COMMENTS: The results of this study can be compared to the results of Comparing GI flora in autistic children to typical children. Some results are similar, such as the higher levels of Bifidobacteria and low levels of Lactobacillus; however, the amount of SCFAs differ. In this article, only butyrate and propionate were measured whereas in Comparing GI flora in autistic children to typical children, all SCFA levels were measured. Teachers can ask students:
- How are the graphs difference in the two articles?
- Are the SCFAs measure with the same unit of measure?
- What are the differences in methodology?
