Gut Flora Causing Autism?

         A study of mice suggests that certain forms of autism may in fact be sprouting from chemical imbalances within the body. Where are these imbalances coming from might you ask? Microbes. Recent studies show that mice with microbes in their gut often have leaks in their intestines, leaving the microbes to invade their blood. They are obtaining high levels of chemicals that are similar to compounds found in the urine of children with autism. These mice are having autistic behavior such as social inclusion and even lacking verbal communication with others. When given a probiotic, the bacteria reduced the amount of leakage and did not correct, but improved their behavior, suggesting this can be done with children as well.

         The author’s wording is critical throughout her writing, as she is very careful to not make specific statements about whether or not all of this is fully true. She gives the evidence and results found with the mice, but does not clearly state it as a guarantee. She goes on to explain that women who suffer from infections or high fever during pregnancy, often have a greater risk of their child having autism, similarly to mice. However, once tested, the mother mice that were given infections, often acquired leaks in their intestines. The author goes into great detail about the kinds of chemicals found in their gut, giving the reader that much more knowledge about what’s going on. However her description is well done, she jumps back and forth between subjects, making it hard to follow. I would say she ended the article quite well with stating, “Though the study is fascinating and important, much more research is needed to establish whether people with autism have similar microbe-related problems” (Saey, Tina Hesman, Autism may be linked to chemicals produced by microbes in the gut).

Introduction to Microbiology

I chose this course because I was really interested in taking another biology class since I haven't taken once since high school. I was even more pleased to find out that it was not a regular biology class, but in fact focused on microbes. It's intriguing because these tiny things that no one can see, are sometimes the things that can kill us.
