Internal cellular sensors make Salmonella dangerous: study

(Phys.org) -- Salmonella becomes dangerously virulent only when molecular sensors within the organism sense changes in the environment, a team of researchers from the Yale School of Medicine and the Yale Microbial Diversity ...

Antibiotic resistant bacteria proliferate in agricultural soils

Infectious diseases kill roughly 13 million people worldwide, annually, a toll that continues to rise, aided and abetted by resistance genes. Now a study, published in the March Antimicrobial Agents and Chemotherapy finds ...

Brewery waste microbes could make biofuels

(PhysOrg.com) -- Anyone cracking open a cold beer is probably not considering the wastewater left over after the beer was brewed. But for Cornell researchers, that vinegary effluent is a scientific playground for devising ...

Gene 'relocation' key to most evolutionary change in bacteria

(PhysOrg.com) -- In a new study, scientists at the University of Maryland and the Institut Pasteur show that bacteria evolve new abilities, such as antibiotic resistance, predominantly by acquiring genes from other bacteria.

Study uses genetic approach to manipulate microbes in gut

We are what we eat, but who are "we"? New, high-powered genomic analytical techniques have established that as many as 1,000 different single-celled species coexist in relative harmony in every healthy human gut.
