Throughout the animal kingdom, mothers transfer microbes to their young while giving birth. Different species of tadpoles acquire specific skin bacteria from mother frogs even though they all live in the same pond with the same bacterial background. Emerging chicken eggs get inoculated with micr... Read More
Wolbachia, a symbiont that resides naturally up to 70% of all insect species, are probably the most prevalent infectious bacteria on Earth. In 2008 Luis Teixeira, now a principal investigator at the Instituto Gulbenkian de Ciência, and other scientists have discovered that Wolbachia can protect ... Read More
You have heard of the leaf-cutting ants1 that meticulously cultivate "their" fungi2 which provide them with nutrients, and that, in addition, host actinobacteria which prevent bacterial and fungal infections of their fungi as well as their own infection by an entomopathogenic fungus3 Metarhizium...

An international team of scientists from Singapore, Thailand, China and Australia has cracked the genetic code of the liver fluke parasite, Opisthorchis viverrini, using a unique DNA analysis technique developed at A*STAR’s Genome Institute of Singapore (GIS).
GIS’s DNA analysis technique ha... Read More
Cambridge scientists have uncovered the mechanism by which bacteria build their surface propellers (flagella) – the long extensions that allow them to swim towards food and away from danger. The results, published this week in the journal Nature, demonstrate how the mechanism is powered by the s... Read More
Biofuels made from plant materials—also known as lignocellulosic biofuels—have promise as a source of sustainable alternative fuels thanks to soil bacterium known as Enterobacter lignolyticus SCF1. SCF1 degrades lignin and decomposes plant cell walls, allowing access to the cellulose sugars that... Read More
Colorectal cancer develops in what is probably the most complex environment in the human body, a place where human cells cohabitate with a colony of approximately 10 trillion bacteria, most of which are unknown. At the 2014 American Association for Cancer Research Annual Meeting in San Diego, re... Read More
Otherwise innocuous bacteria can cause deadly infections when people have surgery or fall ill. To prevent trouble, patients sometimes have their bodies scrubbed clean of Staphylococcus aureus. But it doesn't always work.
That may because the germs thrive in upper recesses of the nose, far fro... Read More
The most detailed analysis to date of the spread of the H1N1 2009 pandemic influenza virus, known informally as ‘swine flu’, has found that short-range travel was likely the primary driver for the 2009 pandemic in the United States, in contrast with popularly accepted views on the way diseases s...

Mothers give a newborn baby a gift of germs -— germs that help to kick-start the infant’s immune system. But antibiotics, used to fight bacterial infection, may paradoxically interrupt a newborn’s own immune responses. A new animal study by neonatology researchers at The Children's Hospital of P...

BERKELEY — People infected with the Human Immunodeficiency Virus (HIV) can stave off the symptoms of AIDS thanks to drug cocktails that mainly target three enzymes produced by the virus, but resistant strains pop up periodically that threaten to thwart these drug combos. Researchers at the Unive... Read More
Using a new technique to track the swimming motion of a single bacterium, researchers have discovered that the movement of the bacterium’s body — not just thrust from the flagellum — allow movement through fluids. The finding could shed new light on the evolution of cell body shape.

Researchers have debated for more than two decades the likely impacts, if any, of global warming on the worldwide incidence of malaria, a mosquito-borne disease that infects more than 300 million people each year. University of Michigan ecologists and their colleagues are reporting the first har... Read More
Whether inhabiting soil, fresh water, or marine ecosystems, bacteria are constantly facing the threat of numerous and effective predators such as protists, nematodes, or phages. To defend against such predation, bacteria have evolved a number of strategies, including getting larger in size, movi... Read More
The 'post-antibiotic' era is near, according to a report released today by the World Health Organization (WHO). The decreasing effectiveness of antibiotics and other antimicrobial agents is a global problem, and a surveillance system should be established to monitor it, the group says. There is ... Read More
Inspired by natural materials such as bone — a matrix of minerals and other substances, including living cells — MIT engineers have coaxed bacterial cells to produce biofilms that can incorporate nonliving materials, such as gold nanoparticles and quantum dots.
These “living materials” combin... Read More
In its early days, ca. 1945-1965, molecular biology was a particularly collegial undertaking, characterized by free sharing of research data and a relative lack of egotistical behavior. The reason for this marvel may well have been that there was so much to discover—so many low hanging fruits—th... Read More
The sprawling citrus orchard that Victor Story toured recently sure looked like a steal at $11,000 an acre. The investors who owned it were going to lose money, and potential buyers such as Story might have stood to reap a handsome reward.
But as he bumped along the 40 acres of groves in a la... Read More
I have the grating feeling that the subject of self-assembly of complex biological structures may not always amass the level of respect it deserves. I reckon that its importance is generally appreciated but, as topics go, it tends at times to be set aside. Yet, this is one of the most magnificen... Read More
A boy with cystic fibrosis develops a chronic and potentially deadly Burkholderia dolosa infection in his lungs. Varieties of genetic mutations allow some strains of the bacteria to survive the dual assaults from his immune system and antibiotics, while others perish. Eventually, the strongest m... Read More
