A discussion with Professor Moselio Schaechter, Distinguished Professor, emeritus at Tufts University School of Medicine, Boston, about his book the Encyclopedia of Microbiology.
Antiretroviral therapy provides life-saving medicine to HIV-infected people but it is not a cure. Long-term exposure to the drugs and the virus itself shorten a person's life, even if they don't develop AIDS. Two HIV/AIDS Disease Teams led by scientists at UCLA and the City of Hope are focused o... Read More

In this BCCDC produced video children from John Filed Elementary School use posters to explain what they have learned about Tuberculosis (TB) infection and disease and how it can be cured. Gitxsan elders discuss their experience with Tuberculosis in the days of the Sanatoria Read More
Health authorities in El Salvador issued a flu epidemic alert, with an average of 14 000 cases a day, exceeding those of dengue fever. Health Minister Maria Isabel Rodriguez told local media that 11 of the 14 departments of the country are the worst affected by respiratory disease.
According ... Read More
Bacteria can elaborate complex patterns of development that are dictated by temporally ordered patterns of gene expression, typically under the control of a master regulatory pathway. For some processes, such as biofilm development, regulators that initiate the process have been identified but s... Read More
To take full advantage of recent increased financial commitments from some governments, international agencies, and philanthropies, accurate and up-to-date mapping of neglected tropical diseases (NTDs) needs to be implemented to help improve the precision of decision-making in NTD control and el...

Every day, millions of microorganisms reach Spain from the Sahara Desert and the Sahel region – by flying. Louis Pasteur demonstrated back in 1861 that germs can move through the air, but it was only recently discovered that bacteria, funguses and viruses can travel thousands of kilometers stuck...

Current methods of diagnosing an infectious disease can take days to weeks. Now a Cambridge, MA-based startup called Pathogenica is developing a way to do it within a day--by reading the DNA sequence of pathogens.
Pathogenica is developing diagnostic tests designed to detect harmful microorga... Read More
In biology and genetics, the concept of epistasis is what gives rise to the whole being more (or less) than the sum of its parts. The quantitative effect of a given mutation upon the traits of an organism has the potential to depend strongly upon the gene versions present in other parts of the g... Read More
Researchers at the University of Pennsylvania have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules.
Using electric fields, the tiny DNA strands are pushed through nanoscale-sized, atomically thin pores in a graphene nanopore platform that ultimatel... Read More
It is widely accepted that the shift in case-fatality rate between waves during the 1918 influenza pandemic was due to a genetic change in the virus. In animal models, the infectious dose of influenza A virus was associated to the severity of disease which lead us to propose a new ... Read More
Buruli ulcer is an infectious disease afflicting thousands of children every year. The difficult-to-cure disease, which is caused by bacteria, occurs in tropical or subtropical climate zones and results in open sores and deformities. For the last two years, the international research consortium ... Read More

One of my big headaches at the moment is a patient — call him Ralph — who appears to be one of the most successful small-time alchemists in all of New York.
He creates gold from dross modern-style, filling his prescriptions every month like clockwork and then selling the unopened bottles for... Read More
