Background: altering the intestinal microbiota or Dysbiosis has been implicated in the changes the behavior of neurodevelopmen- tal and gastrointestinal problems in patients with autism spectrum disorder (ASD). Objective: To evaluate aerobic intestinal micro- biota (AMGI) and rank it beneficial, transitory and enteropathogenic in children with ASD, the Autism Unit-Maternidad Concepcion Palacios. Patients and Methods: From 26/02/2015 to 05/12/2015 were studied experimentally and prospectively 39 children diagnosed with ASD; in this study the AMGI stool samples were used. A survey to collect epidemiological, clinical and neurodevelopmental behavior was applied. Severity classification dysbiosis proposed in grade I, II, III or absent for evaluating the AMGI. Results: There were 27 kids (69.23%) and 12 girls (30.77%) with a mean age of 6.3. Dysbiosis 31 (79.5%), Dysbiosis absent eight (20.5%). Depending on the degree of dysbiosis, 5 (16.13%) Grade I, 7 (22.58%) Grade II, 19 (61.29%) Grade III. The main causative agents of dysbiosis were Klebsiella spp. 16, Proteus mirabilis 8, Streptococcus sp. 6, Serratia marcensces 5, Candida spp. 4. Two children presented MGIA pathogenic Campylobacter coli. Gastrointestinal symptoms: 25,80% abdominal pain, 16.13% diarrhea and 38.7% constipation. Neurodevelopmental disorders: 50% flapping, 34% self-harm, 61% tantrums and 34.3% insomnia. Conclusion: It is necessary to compare this research with a group of children without ASD to confirm the presence of dysbiosis to cau- se impaired MGIA occurs most often in children with ASD.
