In tropical regions, a variety of pathogens such as plasmodium falciparum, larvae of Taenia solium, trypanosoma Brucei, Nipah virus, HIV, mycobacterium leprae and tuberculosis can spread to the nervous system, causing devastating diseases. We have organized the first conference on "Infectious Diseases of the Nervous System: Pathogenesis and Worldwide Impact" at the Pasteur Institute, Paris, September 10 - 13, 2008. Come and join us to learn how major neurotropic parasites, bacteria and viruses spread through the blood brain barrier and interact with neural cells to cause disease.
