Study Identifies Genetic Variation In Tuberculosis Strains
A TIGR comparison of the whole genomes of two strains of the bacterium that causes tuberculosis has found a surprising number of differences, indicating that genetic variation may be more extensive among Mycobacterium tuberculosis isolates than previously thought, and may play an important role in the development of the disease and of human immunity to it.
TIGR Offers Genomics Course
TIGR's genomics course for educators, which is designed to give high school biology teachers a thorough understanding of genomics, will be offered on Saturdays this fall, starting on October 19th.
Sequence Provides Insights Into An Emerging Pathogen's Virulence Mechanism, Allowing for Vaccine Development
An analysis of the whole genome sequence of Streptococcus agalactiae serotype V provides valuable insights into the virulence mechanism of the pathogen, which is a leading cause of pneumonia and meningitis in newborns and the source of life-threatening illnesses in a growing number of adults with deficient immune systems.

Mapping the Mouse Genome
An international research consortium that includes TIGR has published a comprehensive physical map of the mouse genome that provides an important resource for biomedical researchers. The TIGR team, led by Shaying Zhao, sequenced the BAC ends of the mouse genome.

Scientists Find New Markers For Anthrax Isolates
In a pioneering use of genomics as a tool for the forensic analysis of microbes, TIGR scientists have found new genetic markers to distinguish the Bacillus anthracis isolate that was used in last fall's bioterror attack in Florida from closely related anthrax strains.

Through the Canal
We are now out in the warm and saline Caribbean Sea, and the waters are an intense blue. The waters are so blue, there is very little in them: we drop the CTD and barely get 0.25 micrograms of Chlorophyll per liter all the way to the 50 meter mark. The clear waters of the Caribbean are very low...
Miraflores Locks
We passed through the gigantic Miraflores locks on the Pacific side of the Panama Canal this morning, and now we are in front of the Smithsonian Tropical Research Station on Lake Gatun. The Sorcerer has sampled here on two other occasions, so to continue our time course evaluation, we ready the...
Going Green to Blue
As we round the southern most point on our trip we notice that the water has gone from blue to green, and that there appear to be surface current and eddies in the water. We decide to stop and have a look with the CTD. As we lower the instrument from the aft cockpit, we encounter a layer of...
Costa Rican Dome
In Nicaraguan waters is a regular spring upwelling event sometimes referred to as the Costa Rican dome. Winds blow across the Central American Isthmus near Lake Nicaragua and contribute to an upwelling of nutrient rich waters. These nutrients enable phytoplankton to grow, and as we approach the...
Gulf of Tehuantepec
We spend the day transiting the famously capricious Gulf of Tehuantepec, but today winds were calm, and we were able to cut across the bay in good time. At the southern end of the gulf is an underwater seamount, so we maneuver the Sorcerer over the seamount in hopes of encountering an upwelling. An...
Acapulco Harbor, Mexico
There probably isn’t a harbor in Mexico more impacted by tourism and development than Acapulco. We pull into the stunningly beautiful harbor and sample in front of an area of high rise hotels. The depth of the spot we sampled is only 40 feet, so we just take a surface water sample. Of particular...
Sampling Blooms in Cabo Corrientes
Just south of Puerto Vallarta is Cabo Corrientes, and our satellite data indicate a large bloom extending 25 miles off the coast. As we enter the bloom the water turns an intense green, and there are numerous fish feeding in the area. Sampling conditions are ideal: bright sunshine, light winds,...
Puerto Vallarta: Investigating the Influence of Coastal Development
Sampling today starts before sunrise when we arrive at Puerto Vallarta. In conjunction with our Mexican collaborators, we are investigating the influence of coastal development, particularly intensive tourism, on marine microbiota, so we take a sample of surface water in Banderas Bay and leave the...
Strong Winds
Winds have picked up considerably in the last 36 hours, and tonight they are blowing in the 25 to 30 knot range, below gale force but still too strong to safely deploy our instrumentation. We sail past the plankton bloom near Cedros Island without stopping, but you can see the sparkle of the...
Blooms and Clear Skies
We left under clear skies and light winds, and within hours of heading out, we were sampling the waters off of the Coronado Islands near the US/Mexican border and plotting our sampling schedule for the next few days. The team passed around the latest satellite data from SeaWiFS, NASA’s global...
