Cystic fibrosis microorganisms survive on little to no oxygen

Microbes contributing to cystic fibrosis (CF) are able to survive in saliva and mucus that is chemically heterogeneous, including significant portions that are largely devoid of oxygen, according to a study published this ...

Distinct avian influenza viruses found in Antarctic penguins

An international team of researchers has, for the first time, identified an avian influenza virus in a group of Adélie penguins from Antarctica. The virus, found to be unlike any other circulating avian flu, is described ...

Cow manure harbors diverse new antibiotic resistance genes

Manure from dairy cows, which is commonly used as a farm soil fertilizer, contains a surprising number of newly identified antibiotic resistance genes from the cows' gut bacteria. The findings, reported in mBio the online ...

Pathogenic plant virus jumps to honeybees

A viral pathogen that typically infects plants has been found in honeybees and could help explain their decline. Researchers working in the U.S. and Beijing, China report their findings in mBio, the online open-access journal ...

Bacteria use hydrogen, carbon dioxide to produce electricity

Researchers have engineered a strain of electricity-producing bacteria that can grow using hydrogen gas as its sole electron donor and carbon dioxide as its sole source of carbon. Researchers at the University of Massachusetts, ...

Pathogen turns protein into a virulence factor in one easy step

To infect its host, the respiratory pathogen Pseudomonas aeruginosa takes an ordinary protein usually involved in making other proteins and adds three small molecules to turn it into a key for gaining access to human cells. ...
