Tel Aviv University team finds bacteria-killing protein, could replace antibiotics

A group of Israeli researchers has succeeded in isolating a protein that kills bacteria, in what is a first step toward developing a substitute for antibiotics. The substance isolated by a Tel Aviv University team prevents bacteria from dividing, thus destroying them and combatting infections. “... Read More

No cases of MERS virus among haj pilgrims so far: ministry

Saudi Arabia has so far recorded no cases of the deadly MERS coronavirus among pilgrims in the holy city of Mecca for the annual haj season, the Ministry of Health said on Saturday.

The death toll from the respiratory virus in the kingdom, where the strain emerged last year, has reached 51, a... Read More

Discovery of complex symbiotic system comprising the metabolic pathways of mealybugs

Researchers from AIST, in collaboration with the University of Montana (USA), the Open University of Japan, and others, have discovered that two types of bacteria with extremely reduced genomes endocellularly reside in a nested manner within the symbiotic organ of mealybugs that are known as agr...

Increasing toxicity of algal blooms tied to nutrient enrichment and climate change

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

FrameBot: a new tool for those pesky sequencing problems

In their paper in mBio this week, Wang et al present FrameBot, a program that combines frameshift correction and nearest-neighbor identification in one Java-based tool. Read More

Canine distemper in rare Amur tigers poses "significant risk to survival"

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

Seeing How Antibiotics Work

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

HPV Vaccine Is Credited in Fall of Teenagers’ Infection Rate

The prevalence of dangerous strains of the human papillomavirus — the most common sexually transmitted infection in the United States and a principal cause of cervical cancer — has dropped by half among teenage girls in recent years, a striking measure of success for a vaccine against the virus ...

2014 ICAAC Awards Now Accepting Nominations

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

Malaria: A race against resistance

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

Salmonella Jams Signals From Bacteria-Fighting Mast Cells

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).

Where ‘Nightmare Bacteria’ Came From, And How Our Inattention Helped Them Emerge

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...

UC Davis researchers discover molecular target for the bacterial infection brucellosis

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

Learning from a virus: Keeping genes under wraps

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.

Ancient Virus DNA Gives Stem Cells the Power to Transform

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

Fauci: Robust Research Efforts Needed to Address Ongoing, Global Challenge of Antimicrobial Resistance

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

Plasmas attack bacterial cells on several levels

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

Why MERS virus is so scary

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

Heartland virus disease

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...
