New device traps particulates, kills airborne pathogens

A new device called a soft x-ray electrostatic precipitator protected immunocompromised mice from airborne pathogenic bacteria, viruses, ultrafine particles, and allergens, according to a paper published online ahead of print ...

Dust-plumes power intercontinental microbial migrations

Along with pollutants from Asia, transpacific dust plumes deliver vast quantities of microbes to North America, according to a manuscript published online ahead of print in the journal Applied and Environmental Microbiology.

Tracing foodborne pathogens on the farm

(Phys.org)—In 2011, an outbreak of Listeria monocytogenes in cantaloupe led to almost 150 illnesses and 30 deaths. With a spate of recent outbreaks of such foodborne pathogens as Salmonella, Shiga toxin-producing E. coli ...

Bacteria involved in sewer pipe corrosion identified

Microbes corrode sewer pipes from the inside, a process that can lead to spills, bad odors, disease outbreaks, and the need for costly repairs. In a first step towards reducing the corrosion, researchers have identified the ...

The detoxifying effect of microbes

Heavy metals and other toxins frequently contaminate food and water. The culprits read like a litany of bad actors—lead, cadmium, mercury, arsenic, chromium—but their numbers run into the thousands. Microbes have long ...

GI pathogen at lake linked to human fecal contamination

(HealthDay)—Water at beaches along Lake Erie contains a pathogen associated with human fecal contamination, Arcobacter species, which are known to cause gastrointestinal illness in humans, and levels correlate with beach ...

Tooth protection from the sea

(Phys.org) -- A team of dentists and scientists from Newcastle University are developing a new product from a marine microbe to protect dentures, teeth and gums from bacteria in the mouth.

Changing pigs' diets alters the gut microbiota

Including chicory in cereal-based diets of pigs results in profound changes in gut micro-environment, morphology, and microbial population of pigs, according to a study in the June 2012 Applied and Environmental Microbiology. ...

Genes culled from desert soils suggest potential medical resource

Despite their ecologic similarity, soils from three geographically distinct areas of the American southwest harbor vastly different collections of small, biosynthetic genes, a finding that suggests the existence of a far ...
