Endangered Amur tigers (also called Siberian tigers) face challenges from poaching, decimation of their prey base, and habitat fragmentation, but a disease from domestic dogs may be the straw that broke the tiger's back, according to the authors of a study in mBio this week. A team of scientists... Read More
Nutrient enrichment and climate change are posing yet another concern of growing importance – an apparent increase in the toxicity of some algal blooms in freshwater lakes and estuaries around the world, which threatens aquatic organisms, ecosystem health and human drinking water safety.
As t... Read More
One would assume offhand that the pathways for synthesis and assembly of the major constituents of a bacterial cell “talk to each other,” i. e. they are tightly interwoven processes. Tampering with the biosynthesis of one should affect all the others, right? Wouldn’t you expect, for instance, th... Read More
Several African nations could strike a major blow against malaria by sacrificing the efficacy of some older drugs. Can they make it work?
It is September in southeastern Mali, and Louka Coulibaly is standing in the shade of a squat, concrete building, giving instructions to a dozen men and wo... Read More
Help ASM honor deserving colleagues and young investigators by nominating for the Cubist-ICAAC and ICAAC Young Investigator Awards. The Cubist-ICAAC Award recognizes an outstanding scientist who is active in antimicrobial research, while the ICAAC Young Investigator Awards honor a superb young r... Read More
UC Davis scientists have uncovered a potential drug target for the development of an effective therapy against the debilitating, chronic form of the bacterial disease brucellosis, which primarily afflicts people in Mediterranean and Middle Eastern countries.
Brucellosis, which affects about 5... Read More
A protein in Salmonella inactivates mast cells -- critical players in the body’s fight against bacteria and other pathogens -- rendering them unable to protect against bacterial spread in the body, according to researchers at Duke Medicine and Duke-National University of Singapore (Duke-NUS).

Cast your minds back a few months ago, to when the director of the US Centers for Disease Control and Prevention announced, “We have a very serious problem” with “nightmare bacteria,” and the chief medical officer of the United Kingdom backed him up a few days later, describing a “ticking time b...

Treating food products with select bacteriophages - viruses that target and kill bacteria - could significantly reduce concentrations of E. coli, a Purdue University study shows.
An injection of bacteriophages - also known informally as "phages" - nearly eradicated a toxin-producing strain of... Read More
A virus that invaded the genomes of humanity's ancestors millions of years ago now plays a critical role in the embryonic stem cells from which all cells in the human body derive, new research shows.
The discovery sheds light on the role viruses play in human evolution and could help scientis... Read More
By studying how a virus that infects most people at some point in their lives packages its genetic material during infection, an international collaboration of researchers has made discoveries that help scientists better understand virus-host interactions and may open new avenues for therapies.

Given the evolutionary ability of microbes to rapidly adapt, the threat of antimicrobial resistance likely will never be eliminated. Today, many factors compound the problem, including the inappropriate use of antibiotics and a dwindling supply of new medicines, leading to a global crisis of ant... Read More

Six new cases of Heartland virus disease have been identified in residents of Missouri and Tennessee. The cause of this disease appears to be a member of the Phlebovirus genus in the Bunyaviridae family that was first identified in 2009 and appears to be transmitted by the Lone Star tick (Amblyo...

As they destroy bacteria very efficiently, plasmas constitute an alternative to chemical disinfectants and potentially to antibiotics, as well. How they achieve this effect has been investigated by biologists, plasma physicists and chemists at the Ruhr-Universität (RUB). Cold atmospheric-pressur... Read More
The head of the World Health Organization warned the world this week of a new virus, awkwardly dubbed MERS-CoV, found in Saudi Arabia.
"Looking at the overall global situation, my greatest concern right now is the novel coronavirus," Margaret Chan said, calling it "a threat to the entire worl... Read More

It is well known that aquatic birds are a major reservoir of influenza A viruses, and that pandemic human influenza virus strains of the past century derive viral genes from this pool. The recent discovery of two new influenza A viruses in bats suggests that this species may constitute another r... Read More
GUECKEDOU, Guinea, April 8 (Thomson Reuters Foundation) - H iccups, say doctors in this remote corner of Guinea, are the final tell-tale sign of infection by the Ebola virus that has killed more than 100 people since an outbreak began this year.
Then come profuse bleeding, circulatory shock a... Read More
