We all see the world differently, but for those with autism the world can be a particularly confusing jumble of people and places. Autism spectrum disorders affect one in a hundred children in the UK and there is no cure. Autistic individuals often have difficulties with social interaction, respond badly to change and display repetitive behaviours. It is speculated that some of these symptoms may be due to their immune systems over-reacting, causing chronic inflammation. So where do worms come in? The whipworm (pictured), specifically Trichuris suis, infects the intestines of both pigs and humans. Harmful and sometimes fatal to pigs, it is fairly innocuous to humans, and may even decrease inflammation. When an autistic boy was infected with whipworm eggs, he seemed to show improvement in his symptoms. This has spurred a small clinical trial to test if it might work for other people with autism.

BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
BPoD is also available in Catalan at www.bpod.cat with translations by the University of Valencia.
