Of course, probiotics specific to any disease and autism are possible. In order for any probiotic to be specific to autism, intestinal microbiota analyses of children with autism and healthy children in all regions of the country should be conducted using the new generation sequence analysis method, and the intestinal microbiota profiles of children with autism should be revealed. The results of the analyses should also be evaluated with statistical comparisons, and in the light of the scientific data obtained, an accurate and effective probiotic formulation specific to autism is possible. Science should be evidence-based.
