| Abstract | Development of Autism Spectrum Disorders (ASD), including autism, is based on a combination of genetic predisposition and environmental factors. Recent data propose the etiopathogenetic role of intestinal microflora in autism. The aim of this study was to elucidate changes in fecal microbiota in children with autism and determine its role in the development of often present gastrointestinal (GI) disorders and possibly other manifestations of autism in Slovakia. The fecal microflora of 10 children with autism, 9 siblings and 10 healthy children was investigated by real-time PCR. The fecal microbiota of autistic children showed a significant decrease of the Bacteroidetes/Firmicutes ratio and elevation of the amount of Lactobacillus spp. Our results also showed a trend in the incidence of elevated Desulfovibrio spp. in children with autism reaffirmed by a very strong association of the amount of Desulfovibrio spp. with the severity of autism in the Autism Diagnostic Interview (ADI) restricted/repetitive behavior subscale score. The participants in our study demonstrated strong positive correlation of autism severity with the severity of GI dysfunction. Probiotic diet supplementation normalized the Bacteroidetes/Firmicutes ratio, Desulfovibrio spp. and the amount of Bifidobacterium spp. in feces of autistic children. We did not find any correlation between plasma levels of oxytocin, testosterone, DHEA-S and fecal microbiota, which would suggest their combined influence on autism development. This pilot study suggests the role of gut microbiota in autism as a part of the 'gut-brain' axis and it is a basis for further investigation of the combined effect of microbial, genetic, and hormonal changes for development and clinical manifestation of autism. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
