Analysis offers an alternative history for ampicillin resistance

By |2017-12-03T18:23:24+00:00December 3rd, 2017|

A new study by French scientists suggests the rise of ampicillin resistance in a strain of Salmonella may have begun before the antibiotic was ever used in humans. Ampicillin, a widely used broad-spectrum, semi-synthetic derivative of penicillin, was first marketed in the United Kingdom in 1961 and introduced in other European countries shortly thereafter. But it wasn't [...]

But the graph of casesin the US over time looks like the second, fun half of a [...]

Study questions effectiveness of EVS to monitor hospital room cleanliness

By |2017-11-15T20:46:06+00:00November 15th, 2017|

Recently published findings validate the CDC’s recommendation that independent observers provide the most objective approach to monitoring the thoroughness of environmental services staff to clean and disinfect hospital rooms after they are used. The CDC recommends that hospital epidemiologists or infection preventionists who are not part of environmental services (EVS) monitor the environmental cleaning and [...]

EPA Approval Of Bacteria To Fight Mosquitoes Caps Long Quest

By |2017-11-15T20:31:19+00:00November 15th, 2017|

Editor's note: The Environmental Protection Agency has approved the use of mosquitoes infected with Wolbachia bacteria as a "biopesticide" in 20 states and the District of Columbia. The bacteria keep mosquitoes from spreading diseases like dengue and Zika. Back in 2012, NPR's Joe Palca wrote about scientist Scott O'Neill's 20 years of struggle to make [...]

A Clean Slate: Engineering the Gut Microbiome with “Good” Bacteria May Help Treat Crohn’s Disease

By |2017-11-15T20:18:21+00:00November 15th, 2017|

Penn Medicine researchers have singled out a bacterial enzyme behind an imbalance in the gut microbiome linked to Crohn’s disease. The new study, published online this week in Science Translational Medicine, suggests that wiping out a significant portion of the bacteria in the gut microbiome, and then re-introducing a certain type of “good” bacteria that lacks [...]
