MicrobeWorld

This is a database of environmental risk factors, often viruses, bacteria and parasites, that have been implicated in Alzheimer's disease, Bipolar disorder, Multiple sclerosis, Schizophrenia, and Parkinson's disease , all accessible from the home page. In general the degree of risk conferred by these pathogens is far greater than for any gene, although their involvement is hotly contested. In the final analysis bugs and genes probably work together in some way, as highlighted in the related blog.
