Overview

Expertise: Microorganisms from unexplored environments; secondary metabolites produced by marine microbes; bacterial chemical communication; and antibiotic drug discovery

One of the more frightening medical trends today is our growing resistance to antibiotics, which we take for everything from ear infections to life-threatening blood conditions. As people use antibiotics for more and more ailments, the ability of germs and bacteria to mutate and adapt has increased, often making them stronger than the medicines available to treat them.

Pharmacognosy is the study of the medicinal properties of compounds from such natural sources as the ocean and plants. Most of our current antibiotic drugs derive from natural products produced by terrestrial microorganisms, so as we try to stay one step ahead of the pathogens, the most logical next place to look is at marine microbes.

  • Professor Rowley and team say class of cranberry carbohydrates could improve UTI treatment - Biomedical Science Professor David Rowley and his team in the College of Pharmacy have found that a class of complex carbohydrates could enhance treatment of urinary tract infections. Their findings appear in a recent issue of the Journal of Functional Foods, published by the International Society for Nutraceuticals and Functional Foods.
  • $18.8 Million for URI-Based Initiative - The Rhode Island IDeA Network of Biomedical Research Excellence (RI-INBRE), the URI-based initiative that has greatly expanded biomedical research statewide, has been awarded an additional $18.8 million for the program’s continued expansion over the next five years. Professor of Pharmacology and Toxicology Zahir Shaikh has been the principal investigator and program director since the project's inception in 2001.
