Antimicrobial resistance (AMR) is a chilling reality that my patients and I face every day. As an infectious diseases physician, I see increasing numbers of patients with serious or life-threatening infections, and I am running out of antibiotics to treat them. The emergence of MCR-1 and MCR-2—n... Read More
Researchers have discovered the strongest evidence yet linking the Zika virus to the paralytic illness Guillain-Barre syndrome. During the height of the viral epidemic the incidence of Guillain-Barre was 100 times the number of cases usually seen.
Guillain-Barre is a normally rare condition t... Read More
If the previous occupant of a hospital bed received antibiotics, the next patient who uses that bed may be at higher risk for a severe form of infectious diarrhea, according to a new study.
Clostridium difficile (C. diff) diarrhea causes 27,000 deaths each year in the U.S. Hospital patients t... Read More
The night after receiving the news about winning the 2016 Nobel Prize in Physiology or Medicine, microbiologist Yoshinori Ohsumi expressed his eagerness to build a new research center for microbiology and create a system for supporting young scientists.
"Microorganisms support the living worl... Read More
In an attempt to preserve and defend the good name of the salmon fished in his state, Senator Warren Magnuson (D-WA), introduced in 1969 a bill in the US Senate proposing to change the name of Salmonella to the more inoccuous sounding Sanella. In some circles it may seem comforting to th... Read More
The Nobel Prize for Medicine this year went to Dr. Yoshinori Ohsumi of the Tokyo Institute for Technology for his work on autophagy, the process of digesting unneeded or damaged cellular components. This process plays a role in many central cellular activities, with applications ranging from gen... Read More
A rare and improbable mutation in a protein encoded by an influenza virus renders the virus defenseless against the body's immune system. This University of Rochester Medical Center discovery could provide a new strategy for live influenza vaccines in the future.
A new approach to the live fl... Read More

For decades a deadly fungus has been slaughtering amphibians around the world, driving many to the brink of extinction or even beyond.
But now one frog’s recovery shows that, with a little luck and habitat preservation, some amphibians may be able to evolve resistance to the fungus.
In lab... Read More
Laboratory tests show that a cold-tolerant mosquito known as Culex quinquefasciatus can be infected with Zika virus in the laboratory. If confirmed in the field, it would be a troubling development, suggesting the virus would be more difficult to control, and might be able to spread far north of... Read More
A popular antibiotic called rifampicin, used to treat tuberculosis, leprosy, and Legionnaire’s disease, is becoming less effective as the bacteria that cause the diseases develop more resistance.
One of the mechanisms leading to rifampicin’s resistance is the action of the enzyme Rifampicin m... Read More
Ten years ago, Takema Fukatsu, PhD, prime senior researcher and leader, National Institute of Advanced Industrial Science and Technology (AIST) in Japan, was invited to Kyoto University as a symposium speaker of a meeting organized by Kenji Fujisaki, PhD, a researcher in the University's Graduat...

A new study shows that when heat-susceptible bacteria living symbiotically in the guts of insects are exposed to increased temperatures, both the bacteria and the insect are negatively impacted and can die. The study, reported online this week in the journal mBio®, illustrates another way globa... Read More
The LudusScope is an interactive smartphone microscope that can be made entirely out of 3D printed or commonly available materials and is easily assembled by middle school or high school students. Developed by Stanford bioengineer Ingmar Riedel-Kruse, it allows students to interact directly with... Read More
The results of a clinical trial suggest it is possible to modify the body’s response to an infection with a related virus.
The researchers report in Nature Microbiology that antibodies, under specific conditions, can intensify infection with a virus related to the causal organism. This phenom... Read More
Eating slow-release carbs and cutting down on protein may prevent rotten-egg farts according to a study of the gases emitted by human faeces samples.
Farts are mostly composed of odourless gases. There is oxygen and nitrogen from swallowed air, while hydrogen, methane and carbon dioxide are p... Read More
Naturally occurring bacteria could consume pent-up hydrogen gas in nuclear waste repositories to prevent radioactive leaks, say researchers at EPFL.
Scientists may have found an unexpected ally in the long-term disposal of nuclear waste: bacteria. In a recent study, a research team led by EPF... Read More
A team of researchers with members from Italy, Australia, the U.S. and Japan has found that viruses are the main culprit in killing archaea in the deep sea. In their paper published in the journal Science Advances, the researchers describe the techniques they used to study archaea in soil sample... Read More
A new tool that uses a forest-like array of vertically-aligned carbon nanotubes that can be finely tuned to selectively trap viruses by their size can increase the detection threshold for viruses and speed the process of identifying newly-emerging viruses.
"Early detection is important becau... Read More
