The pathogen Escherichia coli O157:H7 can spread, likely airborne, more than one tenth mile downwind from a cattle feedlot onto nearby produce, according to a paper published ahead of print in Applied and Environmental Microbiology. The high percentages of leafy greens contaminated with E. coli ... Read More
Exposure to cigarette smoke has long been associated with increased frequency of respiratory infections—which are harder to treat in smoke-exposed people than in those who lack such exposures. Now Ritwij Kulkarni of Columbia University, New York, NY, and colleagues show that cigarette smoke actu... Read More
European researchers at Linköping University in Sweden are showing how bacteria control processes in human cells through a process called quorum sensing. This phenomenon is where bacteria talk to each other via molecules they themselves produce and is an important process during their proliferat... Read More
Previous research has shown that the overuse of antibiotics has a hand in promoting an antibiotic-resistant strain of bacteria and now a new study published in the journal mBio has found that an antibiotic common to soaps and hand sanitizers actually promotes the growth of Staphylococcus aureus ...
