Researchers have discovered the structure of a key protein on the surface of an unusually large virus called the mimivirus, aiding efforts to determine its hosts and unknown functions.
The mimivirus was initially thought to be a bacterium because it is much larger than most viruses. It was is... Read More
Over the past few years, researchers have gotten a much better idea of the importance of the human microbiome--the trillions of bacteria living in and around our bodies. Now we know that these bacteria can make us more obese, change how our brains work, and are unique to individuals. Although a ... Read More
Nebraska Governor Pete Ricketts declared a state of emergency on Thursday, after federal agriculture officials confirmed a second farm site had tested positive for the rapidly spreading avian flu virus.
The declaration follows earlier, similar actions by governors in Wisconsin, Minnesota and ... Read More
Investigators found that nearly half of the 50 chicken meat samples purchased from supermarkets, street markets, and butchers in Austria contained viruses that are capable of transferring antibiotic resistance genes from one bacterium to another—or from one species to another. "Our work suggests... Read More
The recent discovery of a novel antibody that works in an unusual way might inspire ideas for designing more effective vaccines. Among the common pathogens that could be targeted are urinary-tract infecting strains of E. coli. Read More
UNSW Australia researchers have shown that changing just a single letter of the DNA of human red blood cells in the laboratory increases their production of oxygen-carrying haemoglobin - a world-first advance that could lead to a cure for sickle cell anaemia and other blood disorders. Read More
Tokay geckos harbor bacteria that are resistant to a number of antibiotics, making them a health concern for pet owners, according to a study by University of Georgia researchers.
Tokay geckos, a type of gecko known for the "to-kay" sound it makes, are caught in the wild and often imported in... Read More
Wastewater treatment plants not only struggle removing pharmaceuticals, it seems some drugs actually increase after treatment.
When researchers tested wastewater before and after treatment at a Milwaukee-area treatment plant, they found that two drugs—the anti-epileptic carbamazepine and anti... Read More
Our two square meters of skin act as a defensive barrier against environmental pathogens but is also covered by beneficial commensal bacteria. We live alongside these bacteria without excessive and unnecessary immune responses, which could destroy the skin's function as a barrier and so make us ... Read More
U.S. cases of two deadly types of foodborne pathogens have fallen sharply since 2008, but rates of other key types of foodborne bugs have increased, according to the latest report on nine pathogens tracked by health officials.
"The picture is mixed," said Dr. Patricia Griffin of the U.S. Cent... Read More
At the peak of the Ebola epidemic last fall came a frightening new possibility: a mutation that could allow the disease to spread through the air. Now University of Florida researchers have dispelled this concern using data from current and past Ebola outbreaks.
While concern about airborne E... Read More
Melanin produced by a marine bacteria Bacillus spp. has shown shown to have good anti-inflammatory activity. The pigment had shown to inhibit inflammatory enzymes cycloxygenase, lipooxygenase, myeloperoxide,NO synthase in vitro at a concentration which was non-cytotoxic..This will be a breakthro...

With the threat of multidrug-resistant bacterial pathogens growing, new ideas to treat infections are sorely needed. Researchers at University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences report preliminary success testing an entirely nove... Read More
PhD student Anne Leonard talks through her latest research paper, which shows that people who take part in coastal water sports could be at risk of exposure to antibiotic resistant bacteria.

A major goal of viral oncotherapy – the use of viruses to destroy tumors – is to design viruses that kill tumor cells but not normal cells. Two adenoviruses provide perfect examples of how this specificity can be achieved.
Adenovirus CG0070, designed to treat bladder cancer, and adenovirus O... Read More
Researchers at Harvard T. H. Chan School of Public Health and the Broad Institute have identified a protein on the surface of human red blood cells that serves as an essential entry point for invasion by the malaria parasite. The presence of this protein, called CD55, was found to be critical to... Read More
Monrovia, 8 May 2015 – A week-long campaign to vaccinate more than 600,000 children against polio and measles kicks off today in Liberia, led by the Ministry of Health and Social Welfare, and supported by the Centers for Disease Control (CDC), the United Nations Children’s Fund (UNICEF) and the ...
