Oral history interview with Rita R. Colwell, 2009 Jan. 13
No full textDr. Rita R. Colwell, Distinguished Professor at University of Maryland, College Park and John Hopkins University Bloomberg School of Public Health, was born in Beverly, Massachusetts and received a bachelors of science (1956) from Purdue and a masters of science in genetics from Purdue (1958). Her Ph.D. in oceanography is from the University of Washington. She talks about campus life at Purdue during her student years and her work in Microbiology and Biotechnology University of Maryland, College Park. Colwell talks about her research in studying cholera, combining high tech instruments with molecular biology to make inroads in detecting outbreaks. She also served as Vice President of Academic Affairs. Globally she has focused on addressing emerging infectious diseases and water issues, including safe drinking water for both developed and the developing world. Dr. Colwell served as the first female and the 11th Director of the National Science Foundation (1998-2004). In her capacity as director, Colwell served as co-chair of the Committee on Science of the National Science and Technology Council. Dr. Colwell has been awarded 49 honorary degrees from institutions of higher education including Purdue in 1993 and is the recipient of the Order of the Rising Sun, Gold and Silver Star, bestowed by the Emperor of Japan. In July 2007, she was one of seven recipients of the 2006 National Medal of Science, the nations highest honor for science. Among her affiliation with professional associations are American Institute of Biological Sciences, serving a term as President; American Association for the Advancement of Science, served a term as President; and was Chairman of the Board of Governors of the American Academy of Microbiology

Ocean Warming and Spread of Pathogenic Vibrios in the Aquatic Environment
No full textVibrios are among the most common bacteria that inhabit surface waters throughout the world and are responsible for a number of severe infections both in humans and animals. Several reports recently showed that human Vibrio illnesses are increasing worldwide including fatal acute diarrheal diseases, such as cholera, gastroenteritis, wound infections, and septicemia. Many scientists believe this increase may be associated with global warming and rise in sea surface temperature (SST), although not enough evidence is available to support a causal link between emergence of Vibrio infections and climate warming. The effect of increased SST in promoting spread of vibrios in coastal and brackish waters is considered a causal factor explaining this trend. Field and laboratory studies carried out over the past 40 years supported this hypothesis, clearly showing temperature promotes Vibrio growth and persistence in the aquatic environment. Most recently, a long-term retrospective microbiological study carried out in the coastal waters of the southern North Sea provided the first experimental evidence for a positive and significant relationship between SST and Vibrio occurrence over a multidecadal time scale. As a future challenge, macroecological studies of the effects of ocean warming on Vibrio persistence and spread in the aquatic environment over large spatial and temporal scales would conclusively support evidence acquired to date combined with studies of the impact of global warming on epidemiologically relevant variables, such as host susceptibility and exposure. Assessing a causal link between ongoing climate change and enhanced growth and spread of vibrios and related illness is expected to improve forecast and mitigate future outbreaks associated with these pathogens
Global impact of Vibrio cholerae interactions with chitin
No full textThe interaction of Vibrio cholerae with chitin exemplifies
for microbial ecology a successful bacteria–
substrate interaction with complex and significant
influence on the lifestyle of the bacterium. Chitin is
one of the most abundant polymers on earth and
possibly the most abundant in the aquatic environment,
where its association with V. cholerae has
provided the microorganism with a number of advantages,
including food availability, adaptation to environmental
nutrient gradients, tolerance to stress and
protection from predators. Emergent properties of
V. cholerae–chitin interactions occur at multiple hierarchical
levels in the environment and include cell
metabolic and physiological responses e.g. chemotaxis,
cell multiplication, induction of competence,
biofilm formation, commensal and symbiotic relationship
with higher organisms, cycling of nutrients, and
pathogenicity for humans and aquatic animals. As
factors mediating virulence of V. cholerae for humans
and aquatic animals derive from mechanisms of
adaptation to its environment, at different levels of
hierarchical scale, V. cholerae interactions with chitin
represent a useful model for examination of the role
of primary habitat selection in the development of
traits that have been identified as virulence factors in
human disease
