Art Bell: Somewhere In Time traveled back to February 14, 2002, when Art Bell was joined by Dr. Philip M. Tierno for a discussion on microbiology and diagnostic immunology. Dr. Tierno shared the story of bacteria, viruses, and prions and their myriad effects on human beings. From toxic shock syndrome to Lyme disease to diarrheal infections of the Third World, Tierno offered a broad overview of the impact of these microbes on the world today.
