Genome of Deadly Amoeba Shows Surprising Complexity; Study Reveals Evidence for Lateral Gene Transfer from Bacteria
The genome sequence of the parasitic amoeba Entamoeba histolytica, a leading cause of severe diarrheal disease in developing countries, includes an unexpectedly complex repertoire of sensory genes as well as a variety of bacterial-like genes that contribute to the organism's unique biology. TIGR scientists led the project, which presents the first genome-wide study of an amoeba. About 50 million people a year are infected by the parasite, which causes as many as 100,000 deaths annually.

Genome Comparison of Four Campylobacter Strains Yields New Genetic Markers and Clues to Virulence
In a study that could benefit medical and food-safety research, scientists have used the tools of comparative genomics to find new clues about why some strains of the bacterium Campylobacter - which each year cause more than 400 million cases of gastrointestinal disease - are more virulent than others. The analysis is helping researchers develop more comprehensive detection methods for analyzing human and environmental isolates of the bacteria.
Microbe's Genome Reveals Insights Into Ocean Ecology
Unexpected findings about the genetic makeup of a marine microbe have given scientists a new perspective on how bacteria make a living in the ocean - a view that may prove useful in wider studies of marine ecology. The analysis by TIGR and collaborators of the DNA sequence of Silicibacter pomeroyi found that the metabolic strategies of marine bacterioplankton are more diverse and less conventional than previously thought.
Innovative Metagenomics Strategy Used To Study Oral Microbes
In an innovative new project, TIGR scientists and collaborators are using a metagenomics strategy to explore the complex mix of microbes in the human mouth. The research could help improve the diagnosis and treatment of periodontitis and other oral diseases.
Influenza Genome Sequencing Project Is Launched
TIGR will sequence a large number of human isolates of the influenza virus as part of a landmark influenza genome sequencing project announced Monday by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. The project aims to help scientists better understand how flu viruses evolve as they spread through the population.
TIGR and Virginia Tech Sign Memorandum for New Alliance
A new alliance between TIGR and Virginia Tech University is expected to enhance the Institute's computational and experimental capacity as well as enrich the university's basic research in the life sciences. The Memorandum of Understanding, announced Monday, anticipates joint research projects, shared use of related facilities, adjunct faculty appointments, and opportunities for students to participate in research.
TIGR's Fraser, Salzberg Honored As AAAS Fellows
TIGR President Claire M. Fraser and Senior Bioinformatics Director Steven L. Salzberg have been named as Fellows of the American Association for the Advancement of Science (AAAS) in recognition of their contributions to genomics and bioinformatics.

DNA microarrays vs RNAseq — The winner and new heavyweight champion is?... It’s a draw.
In the past year or so there have been several articles stating that the death of microarray technology is growing near. These proclamations are due to the more recently introduced methodology referred to as RNAseq. At first glance I wrote these claims off as being silly and premature. Over...

Antarctic Epiblog: Leaving McMurdo
Ice formation outside McMurdo Station After we took our samples out at the ice edge, we returned to McMurdo Station for several intense days of demobilization. We had to return all of the large drills, power equipment and camping gear, and spent a considerable time preparing our...
Station IV: The Ice Edge
Our last station in our Ross Sea transect was out at the ice edge, about two miles north of our previous station, Station III. We were interested to see how plankton in the open polynya were different from the phytoplankton we isolated from areas locked in sea-ice. Polynyas are ice-free areas...
Station III: approaching the ice edge
As we were finishing up our work at Station II, we called MacOps, the radio command center for McMurdo Station, and got a 24 hour weather update: a high to the north of Ross Island was blocking a storm in the south, and we were caught in the middle. The prediction: snow, and lots of it. We had...
Station II, Inaccessible Island
The second storm of our trip hit us while we were packing up Station I for a return to McMurdo. The winds began gusting over 50 miles per hour, and the visibility dropped to near zero. We had already packed up camp, but the orders came in over the radio that Condition 1 had been imposed on the...
