New study published on medicinal plant therapy for staph infections

A new study by CSHH postdoctoral fellow Dr. Cassandra Quave and colleagues was published this week in the journal PLoS ONE. The paper reports on the activity of a medicinal plant extract in limiting staphylococcal biofilm formation, and improving therapeutic response to several different antibiotics. Biofilms contribute to the intrinsic antibiotic resistance of staph infections and new therapies are in great demand.Visit this link to access the full paper: “Ellagic acid derivatives from Rubus ulmifolius inhibit Staphylococcus aureus biofilm formation and improve response to antibiotics”.

Agriculture Takes a Toll on Health

A recent study published by Emory Anthropologists Amanda Mummert, Emily Esche, Joshua Robinson, and George Armelagos finds that the transition to agriculture did not quickly afford the health benefits commonly assumed.

Following research published in 1984 by Dr. Armelagos and his colleague Dr. Mark Cohen, the team sought to determine whether bioarchaeological evidence uncovered since the mid-1980s pointed towards a trend of increased health after the transition from hunting and gathering to sedentary agricultural practices.  By conducting a comprehensive literature review of studies taking a whole-body approach to documenting the health of individuals, the authors concluded that agriculture did not, in fact, improve health immediately, but rather was coupled with increased rates of infectious disease and decreased stature.  This research has important implications for our modern food system.  “I think it’s important to consider what exactly ‘good health’ means,” Mummert says in an interview wit Carol Clark.  “The modernization and commercialization of food may be helping us by providing more calories, but those calories may not be good for us. You need calories to grow bones long, but you need rich nutrients to grow bones strong.”
