University of Guelph researchers have created the first-ever vaccine for gut bacteria common in autistic children that may help control some autism symptoms.
Brittany Pequegnat and Guelph chemistry professor Mario Monteiro developed a carbohydrate-based vaccine against the gut bug Clostridium bolteae.
C. bolteae is known to play a role in gastrointestinal disorders, and it often shows up in higher numbers in the GI tracts of autistic children than in those of healthy kids.
More than 90 per cent of children with autism spectrum disorders suffer from chronic, severe gastrointestinal symptoms. Of those, about 75 per cent suffer from diarrhea, according to current literature.
“Little is known about the factors that predispose autistic children to C. bolteae,” said Monteiro.
Although most infections are handled by some antibiotics, he said, a vaccine would improve current treatment.
“This is the first vaccine designed to control constipation and diarrhea caused by C. bolteae and perhaps control autism-related symptoms associated with this microbe,” he said.
