AIBS to cohost symposium on evolution, disease and human health
Date:9/18/2007

y interested in approaches for testing evolutionary hypotheses regarding the importance of natural selection and demographic history in patterning genetic variation. Much of his work deals with development of population genetic theory as well as application of tools to make inference from genome-wide data sets. His recent work with domestic dogs was highlighted in the journal Science.
  • Marc Lipsitch, professor of Epidemiology in the Department of Immunology and Infectious Diseases at Harvard University, will give a presentation titled Sex, Drugs and Natural Selection: Evolutionary Perspectives on Antibiotic Resistance. Lipsitch researches population biology and the evolution of populations of infectious agents in response to selection from host immunity (natural and vaccine induced), antimicrobial agents, and other pressures. A central question in his research is whether widespread use in humans of conjugate vaccines, against a subset of serotypes will result in increased carriage of nonvaccine serotypes (serotype replacement), and if so, what the public health consequences will be. He is also interested in the within-host population dynamics of antimicrobial resistance, the development of improved treatment protocols to reduce selection for resistant bacteria, and the design of studies to measure the selective effect of treatment on antimicrobial resistance. His article The Secret Life of Hospital Bugs: Non-resistant Bacteria Shown to Be Hidden Ally in Fight Against Drug-resistant Strains was recently published in Harvard Focus.
  • Sandra Romero-Steiner, senior investigator in the Meningitis and Vaccine Preventable Diseases Branch of the Division of Bacterial Diseases at the National Center for Immunization and Respiratory Diseases of the Centers for Disease Control and Prevention, will give a presentation titled The Race between Bacterial Adaptation and Protection of the Host." Romero-Steiner has developed numerous methodologies f
