When the gypsy moth -- whose caterpillars have defoliated entire forests -- started spreading westward more than 100 years ago from New England to Wisconsin where they are now, Cornell researchers discovered that its fungal and viral pathogens followed close behind, reported entomologist Ann Haj...

For the first time ever, scientists have succeeded in explaining basic principles of the bacterial transport channel which is formed like a syringe and helps the microorganism deliver the 'virulence factors' to outwit the host's immune system.
The study, by researchers from the Max Planck So... Read More
Failure to add windscreen wash to a vehicle's windscreen wiper water could account for around 20 percent of cases of Legionnaires' Disease, according to the Health Protection Agency.
The disease -- caused by the Legionella bacteria -- is commonly associated with water systems such as air cond... Read More
In this show, I report on four exciting stories: microbial electrosynthesis, desert dust that affects ocean microbes, bacteria dividing unequally, and bacteria that can make you smarter.

I found your podcast through the Microbe World website. Thanks to Microbe World, I've been unable to sate my thirst for knowledge about the microscopic organisms that act as the foundation for our planet. So, I stumble across a podcast about viruses? Hel... Read More
In the quest for alternatives to soybeans, palm, and other edible oilseed plants as sources for biodiesel production, enter an unlikely new candidate: A fungus, or mold, that produces and socks away large amounts of oils that are suitable for low-cost, eco-friendly biodiesel.
That's the topic... Read More
Scientists who advised the World Health Organization on its influenza policies and recommendations—including the decision to proclaim the so-called swine flu a "pandemic" had close ties to companies that manufacture vaccines and antiviral medicines like Tamiflu, a fact that WHO did not publicly ...

A team of researchers at Childrens Hospital Los Angeles (CHLA), along with colleagues from the Keck School of Medicine of the University of Southern California and the Universite Auvergne, France, have discovered an important role for a small, naturally occurring protein called interleukin-10 (I...

Rotavirus vaccine should not be administered to infants with severe combined immunodeficiency (SCID), according to the Centers for Disease Control and Prevention (CDC) and US Food and Drug Administration (FDA)-approved prescribing information and patient safety labeling.
Both monovalent (RV1)... Read More
The same mutated gene that makes humans more susceptible to the potentially fatal West Nile virus is also responsible for the virus affecting horses, according to scientists at the University of Adelaide, Australia.
A naturally occurring mutation of the OAS1 gene has now been confirmed as inc... Read More
A year and a half after traveling abroad, one might think he's free and clear of infection.
But a 25-year-old man in California headed to the emergency room last year with a burning feeling and something squiggling under the white of his eye.
Doctors at the Highland General Hospital Depa... Read More
Scientists have long known that certain types of bacteria boost the immune system. Now, Loyola University Health System researchers have discovered how bacteria perform this essential task.
Senior author Katherine L. Knight, PhD. and colleagues report their discovery in a featured article in ... Read More
Researchers have discovered a new strain of bacteria that can produce non-toxic, comparatively inexpensive "rhamnolipids," and effectively help degrade polycyclic aromatic hydrocarbons, or PAHs -- environmental pollutants that are one of the most harmful aspects of oil spills.
Because of its ... Read More
A virus infection can incite the body to attack its own nerve tissue by activating rare, disease-fighting cells with receptors for both viral and nerve proteins. The dual-receptor observation suggests a way nerve damage might be triggered in susceptible young adults afflicted with multiple scler... Read More
Scientists at the University of Kent and University College Cork have manipulated simple bacteria into constructing internal compartments where biofuels and vaccines can be produced.
These micro-compartments eventually occupy almost 70 percent of the available space in a bacteria cell, enabli... Read More
A University of Iowa and University of Nebraska study has revealed the structure of an important HIV protein attached to the human protein that the virus hijacks during infection. The structural information might help researchers develop drugs that disrupt HIV replication. Image shows structure ... Read More
Four years ago at age 78, R., a retired professional known as much for her small-town Minnesotan resilience as her commitment to public service, developed a fleeting rash over her left chest. The rash, which turned out to be shingles, or herpes zoster, was hardly noticeable.
But the complica... Read More
U.S. regulators need to provide a clear path for drug companies to develop new antibiotics and should consider offering financial incentives, experts told a Congressional panel on Wednesday.
They said doctors are running out of effective antibiotics, yet inconsistent regulatory guidelines at ... Read More
Analysis of the protein structure of the 'motor' of motile bacteria at high resolution by Saori Maki-Yonekura and Koji Yonekura of the RIKEN SPring-8 Center, Harima, and Keiichi Namba of Osaka University has revealed the mechanism for transitioning between different movements.
The flagellum h... Read More
