The Infection-Chronic Disease Link Strengthens
Ricki Lewis | Sep 3, 2000 | 6 min read
Infection" is usually associated with an oozing sore, a bout with the flu, or an outbreak in some exotic place. But infectious organisms lie behind many chronic illnesses too, and an increasingly molecular approach to diagnosis is clarifying some of these relationships. An invited panel discussed "The Infectious Etiology of Chronic Diseases" at the second International Conference on Emerging Infectious Diseases, held in Atlanta July 16-19. Chronic diseases take a huge toll. "In the [United St

New Era in Vaccine Development
Nadia Halim | Apr 16, 2000 | 6 min read
When all fails, try a new attack. That's exactly what researchers do when they use genome sequence data to develop vaccine candidates against the most difficult pathogenic adversaries. Recent efforts are revealing previously unknown microbial genes that may encode proteins important in triggering immunity. "Whole-genome data provides insight into all the features of [organisms] including access to virtually every single antigen that may provoke an immune response," explains Michael Gottlieb, pa
