Antibiotic resistance in the natural environment is rising despite tighter controls over our use of antibiotics in medicine and agriculture, Newcastle University scientists have found.
Bacterial DNA extracted from soil samples collected between 1940 and 2008 has revealed a rise in background ... Read More
Scientists have identified a strain of antibiotic-resistant tuberculosis that thrives in the presence of rifampin, a front-line drug in the treatment of tuberculosis. The bacterium was identified in a patient in China and is described in a study by researchers at the Johns Hopkins Bloomberg Scho... Read More
A report published in the new journal Science Translational Medicine has made an interesting discovery concerning the relationship between sugar intake and the balance of intestinal flora. Researchers have discovered that a diet high in sugar and fat substantially alters the bacterial compositio... Read More
In a novel study, researchers from University of Gothenburg, Sweden have found that the cellulose produced by bacteria could be used to develop artificial blood vessels in the future.
They say that bacterial cellulose carries a lower risk of blood clots than the synthetic materials currently ... Read More
Staphylococcus aureus causes far more serious infections than previously realised, with more than 3,000 Swedes affected every year, reveals a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden.
To date there have been no reliable data on just how common this often dea... Read More
Researchers from the La Jolla Institute for Allergy & Immunology will take aim at several of the world's most dangerous infectious diseases — tuberculosis, malaria and dengue virus — in a five-year, $18.8 million federally funded set of projects seeking to make new inroads toward vaccines agains...

On Dec. 1, 2009, the United States Department of Energy notified the University of Chicago Medical Center that it had full approval to “commence research operations” at the newly constructed Howard T. Ricketts Laboratory, operated by the Medical Center to study the organisms that cause infectiou... Read More
Researchers at Albert Einstein College of Medicine of Yeshiva University have developed a new approach for treating and healing skin abscesses caused by bacteria resistant to most antibiotics. The study appears in the journal PLoS One.
Abscesses are deep skin infections that often resist anti... Read More
The often feared and sometimes deadly infections caused by MRSA -- methicillin-resistant Staphylococcus aureus -- are now moving out of hospitals and emerging as an even more virulent strain in community settings and on athletic teams, and raising new concerns about antibiotic resistance.

The poorest people are not only poor. They are also chronically sick, making it harder for them to escape poverty. A new global initiative may break the vicious cycle:
A group of seven tropical diseases, mostly caused by parasitic worms, afflict a billion impoverished people worldwide. They s... Read More
Mold and mildew may be doomed. Researchers are closer to understanding how these and other fungi grow. "Fungi have a big impact on our dinner plate," said Dr. Brian Shaw, Texas AgriLife Research plant pathologist. "We tend to think that getting food on the table is easy. But fungi are major dise...

Millions of New Yorkers were immunized against smallpox within a few weeks in April 1947. The stimulus for this mass immunization was the importation of smallpox by a businessman who had acquired the disease during his travels. While we are in the middle of a massive influenza immunization campa... Read More
The war pitting researchers and clinicians against a growing array of tuberculosis bacteria strains that are resistant to one of more antibiotics has taken a disturbing turn.
U.S. and Chinese researchers reported Monday a strain of bacteria that is not only immune to one of the main drugs in ... Read More
Researchers in Brazil have estimated the growth timeline of a bacterium that causes orange juice spoilage during shelf life (approximately 6 months) and developed a safe and inexpensive filling, cooling, and storage protocol that inhibits bacterial growth and offers an alternative to other propo...

Pomegranates have already been hailed as a super-food but a team of scientists from Kingston University in South West London has found a new use for the deep red fruit. The team, led by Professor Declan Naughton, has discovered that the rind can be turned into an ointment for treating MRSA and o... Read More
When Allison Hamilos came to the Massachusetts Institute of Technology last year, she dreaded having to take the mandatory general chemistry course for freshmen. Eyeing a future in medicine, she couldn’t see much point in learning chemistry.
“I didn’t like chemistry at all in high school,” s... Read More
Michelle Barnes never imagined that her vacation to Uganda would make her a medical celebrity.
Ms. Barnes, 44, became ill in January 2008, a few days after returning home to Golden, Colo. At first, she seemed to have a typical case of traveler’s diarrhea, but she soon worsened. She broke out ... Read More
“And, of course,” added Kathleen Sebelius, after summing up the accomplishments of eight months of battling swine flu, “we’ve taught everyone how to sneeze.”
