FOR IMMEDIATE RELEASE Monday, April 23, 2007

WHAT:		The unfortunate deaths of three organ transplant recipients in Australia this past January has led to the discovery of a new virus. All three had received organs from the same deceased donor in December, and their closely spaced deaths suggested their transplants might have exposed them to a deadly infectious agent. When investigators at the Victorian Infectious Diseases Reference Laboratory in Melbourne applied all the standard tests, however, they could not identify any known pathogen. So the Australian team turned to scientists at the Greene Infectious Disease Laboratory of the Mailman School of Public Health of Columbia University, who have been developing new techniques for diagnosing infectious diseases with funds from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. Partnering with the company 454 Life Sciences, the Columbia University team applied a high-throughput technology that can sequence hundreds of thousands of bits of DNA simultaneously. Then, using bioinformatics algorithms they had created, the team sorted through the data and identified a new infectious agent—a virus that was sufficiently different from any known virus that it could not have been detected using existing diagnostic methods. By assembling additional genetic sequences, the researchers determined that the new virus is related to, but distinct from, known strains of lymphocytic choreomeningitis virus (LCMV), which has been implicated in a small number of cases of disease transmission by organ transplantation. The knowledge of the genetic sequence of this new virus will enable improvements in screening that may enhance the future safety of organ transplantation.

NIAID is a component of the National Institutes of Health. NIAID supports basic and applied research to prevent, diagnose and treat infectious diseases such as HIV/AIDS and other sexually transmitted infections, influenza, tuberculosis, malaria and illness from potential agents of bioterrorism. NIAID also supports research on basic immunology, transplantation and immune-related disorders, including autoimmune diseases, asthma and allergies.

The National Institutes of Health (NIH)—The Nation's Medical Research Agency—includes 27 Institutes and Centers and is a component of the U. S. Department of Health and Human Services. It is the primary federal agency for conducting and supporting basic, clinical and translational medical research, and it investigates the causes, treatments and cures for both common and rare diseases.
