Chemist Wencewicz receives teacher-scholar award

Tim Wencewicz, assistant professor of chemistry in Arts & Sciences, has been recognized with a 2019 Camille Dreyfus Teacher-Scholar Award. He will use the funding for his research to help develop new antibiotics, to combat antibiotic resistance and to improve the university’s organic chemistry curriculum.

Specialist enzymes make E. coli antibiotic resistant at low pH

New research from Arts & Sciences suggests that many “redundant” enzymes are actually specialists that ensure maximal growth across different environments. They also seem to increase resistance to antibiotics in conditions like those in the GI tract or urinary tract — raising concerns that current antibiotic susceptibility tests are inadequate.

Wencewicz wins Sloan fellowship

The Alfred P. Sloan Foundation announced Feb. 15 that Timothy A. Wencewicz, assistant professor of chemistry in Arts & Sciences at Washington University in St. Louis, has been awarded a 2018 Sloan Research Fellowship. He is among 126 outstanding U.S. and Canadian researchers selected as fellowship recipients this year.
Seventy generations of bacteria

Seventy generations of bacteria

As scientists look for replacements for our dwindling stock of antibiotics, the evolution of resistance is never far from their minds. Washington University in St. Louis biologist R. Fredrik Inglis explored the ability of bacteria to become resistant to a toxin called a bacteriocin by growing them for many generations in the presence of the toxin.

For kids prone to wheezing with respiratory infections, early antibiotics help​​​

In children whose colds tend to progress and lead to severe wheezing and difficulty breathing — such that they are given oral corticosteroids as rescue therapy — researchers have shown that giving a common antibiotic at the first sign of symptoms can reduce the risk of the episode developing into a severe lower respiratory tract illness.
