Smartphones Are Great for Sharing Bacteria

iphone-microbe

Smartphones’ proximity to people’s ears, nose and mouth make them a good vector for transferring microbes. Bacteria and other infectious agents on smartphones can cause the flu, pinkeye, or diarrhea. Lab tests show that most phones have abnormally high levels of coliforms, a bacteria stemming from fecal contamination.

Filamentous Bacteria Act as Living Power Cables

desulfobulbus-seafloor-power-cable

The filamentous bacteria Desulfobulbus can function as living power cables in order to transmit electrons thousands of cell lengths away. The bacteria, which are only a few thousandths of a millimeter in length and are invisible to the naked eye, can form a multicellular filament that can transmit electrons across a distance as large as 1 cm under the right conditions.

In the Rocky Mountains, the South Platte River system flows east through the Coloradan plateau that has plenty cattle ranches, sheep pastures, dairy farms, and water treatment plants. A new survey shows how human activities have affected the concentrations of antibiotic-resistant genes in the watershed.

Prevalence of Multi-Drug Resistant E. Coli Rising ICAAC 2 Reports

ESBL-Ecoli

Infections with multi-drug resistant E. coli, which is also known as ESBL (extended spectrum beta-lactamase), have been assumed to be a hospital phenomenon. A recent analysis presented at The Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) surveyed records from five hospital across the USA (New York, Pennsylvania, Michigan, Texas, and Iowa) and identified 291 cases of ESBL E. coli infections over 12 months, but also found that 107 patients (37%) had acquired infections before they entered a hospital.
