Five rare bacteria found in the intestines of children with autism

The medical profession has never had a set of methods that can quickly and accurately adapt to children with autism, which makes it easy for patients to delay receiving treatment. A study by the Chinese University School of Medicine found that the intestinal microecological development of children with autism is higher than that of the same age


The medical profession has never had a set of methods that can quickly and accurately adapt to children with autism, which makes it easy for patients to delay receiving treatment.

A study by the Faculty of Medicine of Chinese University found that the development of intestinal microecology of children with autism is slower than that of children of the same age, and five types of bacteria that are rarer in ordinary children were found. The sensitivity of children with autism can reach 80%.


A study by the Faculty of Medicine of CUHK collected 128 stool samples from children aged 3 to 6 and compared the types, quantities and related functions of bacteria. Half of them were autistic patients. The result found that the intestinal microbiota of children with autism is more common. There are obvious differences in children.

Among them, there are five types of bacteria in the intestines of children with autism, which are relatively rare in ordinary children.

Studies have also shown that there are significantly more clostridia in stool samples of children with autism, which can produce toxins that damage the central nervous system.

In addition, bacteria related to neurotransmitter activity are also greatly reduced in the intestines of children with autism.

Under normal circumstances, the intestinal microecology should change with age, and the types become richer. However, studies have found that the intestinal microecology of children with autism is significantly lagging behind the development of children of the same age, reflecting the intestinal microecology of autistic patients. The ecological development is different, which has appeared in the early stage.

Professor Huang Xiujuan, deputy director of the Gut Microbiota Research Center, School of Medicine, CUHK, pointed out that this is the first study in the world to find that the gut microbiota is related to the diagnosis of autism. Children with autism have abnormal development of the gut microbiota and are behind the same age. Children, so the intestinal microecological changes that have occurred when they are young, or play an important role in the pathogenesis of autism, are worthy of further exploration.

Help make up for the lack of objective screening methods for the diagnosis of autism in the medical community

Chen Jialiang, dean of the Faculty of Medicine of CUHK and director of the Gut Microbiota Research Center, pointed out that this study is expected to make up for the lack of objective screening methods for the diagnosis of autism in the medical community.

There is a lot of room for exploration in the development direction of using fecal bacteria detection as a non-invasive inspection tool for predicting autism.

Changes in the gut microbiota have been shown to affect mood, pain tolerance, cognitive ability, behavior and mental health.

The imbalance of the intestinal microecology can also cause many nervous system problems, such as depression, so the intestinal microecology has been dubbed the "second brain".

Autism Awareness Day│SEN parents are discriminated against when they take their children out: they don’t understand that they think that young people with mental illness and autism won the Special Olympics silver medal. Gu Dingxuan is a care ambassador: no one should be labeled as a caring father to give up full-time care for his autistic son Work sighs that after the age of 6 the government supports a great reduction in feelings of hesitation, CUHK Medical School develops new technology to calculate the risk recognition rate of autism for children over 6 years old reaches 90%
