She’s just 5’5” and quiet, but don’t let her demure looks fool you—she’s a ruthless killer who moves at the speed of light. Meet Tru-D, the newest member of Vancouver General Hospital’s (VGH) Housekeeping and Infection Control teams. Tru-D SmartUVC, or “Trudi” as staff affectionately call her, is a superbug slaying robot being piloted at VGH.

The World Health Organization says a yellow fever booster vaccination given 10 years after the initial shot isn't necessary. The U.N.'s global health agency said Friday that its expert group on immunization believes a single dose of vaccination is sufficient to confer lifelong immunity against the disease.
The Indian government announced the development of a new low-cost vaccine proven effective against a diarrhea-causing virus that is one of the leading causes of childhood deaths across the developing world. The Indian manufacturer of the new rotavirus vaccine pledged to sell it for $1 a dose, a significant discount from the cost of the current vaccines on the market.
In the summer of 1968, a new strain of influenza appeared in Hong Kong. This strain, known as H3N2, spread around the globe and eventually killed an estimated 1 million people. A new study from MIT reveals that there are many strains of H3N2 circulating in birds and pigs that are genetically similar to the 1968 strain and have the potential to generate a pandemic if they leap to humans.
Two respiratory viruses in different parts of the world have captured the attention of global health officials — a novel coronavirus in the Middle East and a new bird flu spreading in China. Last week, the coronavirus related to SARS spread to France, where one patient who probably caught the the disease in Dubai infected his hospital roommate.
Mosquitoes are deadly efficient disease transmitters. Research, however, demonstrates that they also can be equally adept in curing diseases such as malaria. A new study shows that the transmission of malaria via mosquitoes to humans can be interrupted by using a strain of the bacteria Wolbachia in the insects.
Bacteria on a surface wander around and often organize into highly resilient communities known as biofilms. It turns out that they organize in a rich-get-richer pattern similar to many economies, according to a new study. This is the first study identify the strategy by which bacteria form the micro-colonies that become biofilms, which can cause lethal infections.
A 65-year-old Frenchman is hospitalized after contracting France's first case of a deadly new respiratory virus related to SARS, and French health authorities say they are trying to find anyone who might have been in contact with him to prevent it from spreading.
The tick-borne Lone Star virus has been conclusively identified as part of a family of other tick-borne viruses called bunyaviruses, which often cause fever, respiratory problems and bleeding, according to new research. What made the work especially promising was the speed at which the virus was definitively identified.
A handheld diagnostic device that MGH investigators first developed to diagnose cancer has been adapted to rapidly diagnose tuberculosis and other important infectious bacteria. New research describes portable devices that combine microfluidic technology with nuclear magnetic resonance (NMR) to not only diagnose these important infections, but also determine the presence of antibiotic-resistant bacterial strains.
Even bacteria have a kind of “immune system” they use to defend themselves against unwanted intruders– in their case, viruses. Scientists are now able to show that this defense system is much more diverse than previously thought and that it comes in multiple versions.
Scientists used lab-grown human lung cells to study the cells’ response to infection by a novel human coronavirus (called nCoV) and compiled information about which genes are significantly disrupted in early and late stages of infection.
They sweep. They swab. They sterilize. And still the germs persist. In U.S. hospitals, an estimated 1 in 20 patients pick up infections they didn't have when they arrived, some caused by dangerous 'superbugs' that are hard to treat. The rise of these superbugs, along with increased pressure from the government and insurers, is driving hospitals to try all sorts of new approaches to stop their spread.
In an advance toward coping with bacteria that shrug off existing antibiotics and sterilization methods, scientists are reporting development of a new family of selective antimicrobial agents that do not rely on traditional antibiotics.
Chinese scientists have for the first time found strong evidence of how humans became infected with a new strain of bird flu: from chickens at a live market. Chinese scientists compared swabs from birds at markets in eastern China to virus samples from four patients who caught the new H7N9 virus. The scientists found the virus from one patient was nearly identical to one found in a chicken.
A lethal new strain of bird flu that emerged in China over the past month appears to jump more easily from birds to humans than the one that started killing people a decade ago, World Health Organization officials said Wednesday. Scientists are watching the virus closely to see if it could spark a global pandemic.
U.K. authorities say a 25-year-old man is suspected to have died from measles as an epidemic continues to sweep across south Wales. The outbreak has led to more than 800 infections and renewed discussions over the failure of some parents to vaccinate their children against the potentially fatal virus.
There's no evidence a new bird flu strain is spreading easily among people in China even though there may be sporadic cases of the virus spreading to people who have close contacts with patients, the World Health Organization said Friday. Fifteen global and Chinese health experts are on a mission in Beijing and Shanghai to learn more about the H7N9 bird flu virus that has killed 17 people and sickened 70 others.
Health officials are seeing more food poisonings caused by a bacteria commonly linked to raw milk and poultry. A study released Thursday said campylobacter cases grew by 14 percent over the last five years. The Centers for Disease Control and Prevention report was based on foodborne infections in only 10 states- about 15 percent of the American population.
Researchers have discovered how the protein that blocks HIV-1 from multiplying in white blood cells is regulated. HIV-1 is the virus that causes AIDS, and the discovery could lead to novel approaches for addressing HIV-1 "in hiding"– namely eliminating reservoirs of HIV-1 that persist in patients undergoing antiretroviral therapy.
The U.S. Department of Agriculture says a Louisiana-based meat packing company has expanded a recall of meat products because of possible bacterial contamination. No illnesses have been reported. The Manda Packing Company recall announced this past week now includes 468,000 pounds of meat.
A new broad range antibiotic has been found to kill a wide range of bacteria, including drug-resistant Staphylococcus (MRSA) bacteria that do not respond to traditional drugs. The antibiotic, Epimerox, targets weaknesses in bacteria that have long been exploited by viruses that attack themeria.
Tumor necrosis factor– normally an infection-fighting substance produced by the body– can actually heighten susceptibility to tuberculosis if its levels are too high. A new study shows how excess production of this disease-cell destroyer at first acts as a TB germ killer. But later the opposite occurs: Too much tumor necrosis factor encourages TB pathogens to multiply in the body.
U.S. doctors are prescribing enough antibiotics to give them to 4 out of 5 Americans every year, an alarming pace that suggests they are being overused, a new government study finds. Overuse is one reason antibiotics are losing their punch, making infections harder to treat.
In the search for new antibiotics, researchers are taking an unusual approach: They are developing peptides, short chains of protein building blocks that effectively inhibit a key enzyme of bacterial metabolism. The road from gene to protein has an important stop along the way: ribonucleic acid, or RNA.
There may be nearly four times as many people infected with the tropical disease dengue globally than was previously believed, according to a new study. The World Health Organization has estimated there are about 50 million to 100 million cases of dengue, also known as "break-bone fever," every year.
