Overview

Until recently, nature has been the most effective bioterrorist; however the ability to create genetically engineered microbes is enabling man to catch up. Recognizing the dangers inherent in microbes both natural and maliciously designed, the Academy's Genomic Medicine and Emerging Infectious Diseases Discussion Groups convened a joint session to encourage scientific discourse on the subject. Three leading microbial detectives talked about the new DNA-based tools that help identify disease-causing bacteria, trace their heritage and, most importantly, distinguish natural from nefarious.

Paul Keim described how he has applied genomics in investigations of anthrax, plague, and tularemia. Barry Kreiswirth discussed current genotyping techniques, particularly the mapping of insertion sequence IS6110, which scientists monitor as it moves around on a mycobacterial genome, and the polymerase chain reaction (PCR)-based techniques of strain-specific mycobacterial interspersed repeat unit (MIRU) analysis and spacer oligonucleotide typing (spoligotyping). David Stenger outlined recent developments in sequence-based microbial surveillance.

Speakers

Paul Keim, PhD

Northern Arizona University
Translational Genomics Research Institute
e-mail | web site | publications

Paul Keim is head of the Keim Genetics Laboratory, an Arizona Regents Professor, and the Cowden Endowed Chair in Microbiology at Northern Arizona University. He also serves as the division director of pathogen genomics at the Translational Genomics Research Institute (TGen). Bioweapon genomics, especially phylogenetic and high-resolution strain identification, is Keim's major research area. It was his laboratory's ground breaking work on hypermutable loci in Bacillus anthracis that enabled them to quickly identify the bacilli used in the October 2001 bioterrorism attacks. Since then Keim's group has developed similar genetic tools for all major bacterial biothreats.

Keim serves on the National Research Council committee that monitors biological weapons facilities in the former Soviet Union. He is a member of the U.S. scientific team that inspects abandoned bioweapons sites in Russia and Central Asia. The National Institutes of Health also appointed Keim to the National Science Advisory Board for Biosecurity, where he recently chaired the communications working group. Keim also has a longtime affiliation with the Los Alamos National Laboratory.

Keim earned his PhD in plant biochemistry from the University of Kansas in 1981. He was a postdoctoral fellow and research assistant professor with Karl G. Lark at the University of Utah, where he worked on the genomic analysis of bacteria, plants, and mammals. Keim went on to Iowa State University as a biotechnology research associate, combining molecular genetic analysis with population and quantities genetics of the soybean. This investigation yielded some of the original genetic markers used to identify quantitative biological traits. In 1988 Keim joined biological sciences faculty at Northern Arizona University and has been there ever since.

Barry Kreiswirth, PhD

Public Health Research Institute
e-mail | web site | publications

Barry Kreiswirth joined the Public Health Research Institute (PHRI) in 1978 as a graduate student working on the molecular biology of Staphylococcus aureus and fourteen years later, in response to the New York City outbreak, became the director of its first Tuberculosis Center. Initially established as a genotyping laboratory, it now has one of the largest mycobacterial strain and DNA fingerprint libraries in the world. The Center is best known for its characterization of the highly multidrug-resistant W strain of M. tuberculosis.

Scientists at PHRI's TB Center have always worked closely with both the Centers for Disease Control and the New York City Department of Health to integrate their molecular tools into tuberculosis control programs. During the last decade, the Center has extended its local collaborations to include the New Jersey Department of Health and Human Services and the Wadsworth Center in Albany, New York. Globally, the Center works with researchers and resources mycobacterial specimens from Russia, South Africa, the Czech Republic, India, and Egypt.

Despite a major investment in tuberculosis research, the Center has not abandoned work on Kreiswirth's initial interest, the molecular typing of methicillin resistant S. aureus (MRSA). A rapid DNA-sequenced-based genotyping test differentiating one S. aureus isolate from another has recently been developed. The approach has been adapted to a variety of nosocomial pathogens and is now used to construct a nosocomial surveillance database in collaboration with the New Jersey Department of Health and Hospitals.

David A. Stenger, PhD

U.S. Naval Research Laboratory
e-mail | web site | publications

David Stenger is a principal investigator and head of the Laboratory for Biosensors and Biomaterials at the Center for Bio/Molecular Science and Engineering (CBMSE). His major area of research is biological detection with a focus on microarray-based functional genomics and bioinformatics algorithm development.

Stenger was awarded a PhD in biophysics from the State University of New York at Buffalo in 1989. After graduation, Stenger continued to work in the university's membrane biophysics laboratory at Roswell Park Cancer Institute investigating the fundamental properties of artificial lipid and intact biological membranes. While there, Stenger used his experience with membrane fusion techniques to generate lymphocyte-derived antibody-producing hybridoma lines. In 1992 Stenger joined the CBMSE where he worked on the characterization and applications of self-assembled monolayer formations. He also investigated cell-based biosensor development as well as neural stem cell isolation, culture, and differentiation.

Stenger serves as an external reviewer for the Defense Threat Reduction Agency Biological Defense Program. He has also acted as a representative from the Department of Defense to the Central Intelligence Agency's Neuroscience Program. Stenger has received numerous citations including the Navy Unit Commendation Award, the Berman Research Publication Award, and a Special Intervention Award from the U.S. Navy.
