Research Interests:

The principal interests of the laboratory are: 1) anaerobic bacteria and their role in disease and 2) intestinal microflora and its role in health and disease. Specific techniques utilized include anaerobic culture, gas-liquid chromatography, antimicrobial susceptibility testing, polymerase chain reaction (PCR), real-time PCR, cloning of bacterial genes, and 16S rRNA and other gene sequencing. Specific disease-related interests include rapid, quantitative determination of the bacteriology of wound infection (and other infections) by molecular techniques; developing simplified procedures for rapid, accurate identification of anaerobic bacteria; small bowel overgrowth in irritable bowel syndrome; role of intestinal bacteria in profound constipation (one bowel movement every 3 weeks); role of intestinal bacteria in autism; antibiotic-associated diarrhea and colitis; and role of intestinal bacteria in autoimmune disease. Individual areas of interest in the fields of anaerobic bacteriology or intestinal microbial flora may be welcomed/accommodated.

Examples of specific projects in which Fellows could be involved that would lead to one or more publications include: antimicrobial susceptibility testing with a new antimicrobial; case reports of unusual or instructive infections involving anaerobic bacteria; and studying, and writing up as new species or other taxa, anaerobic bacteria that clearly do not fit into present taxa. We would certainly welcome Fellows seriously interested in research who would like to learn modern techniques and apply for a Career Development Award with the VA after completion of their Fellowship.
