that analyzed both modern animals and museum specimens dating back as far as 180 years found a pattern reflecting human use of antibiotics. There was some good news in the study: It found that antibiotic resistance levels in bears decreased in recent years, suggesting that recent controls on antibiotic use and management have had a positive effect.
A moose grazes on April 16 near the FedEx terminal at the Ted Stevens Anchorage International Airport. Moose are found throughout Anchorage. On the positive side, the work has become effective hands-on education for enthusiastic student researchers, who are able to do lab work that goes beyond an academic exercise and has real-life significance, Leu-Burke said. Her students carry fecal-collection kits in their backpacks, even during spring break, a prime collection period, and she is also busy during that time of the year. “That’s why I’m never off on spring break,” she said.
Grace Leu-Burke, a University of Alaska assistant professor leading the project that is monitoring antibiotic resistance in moose scat, holds one of the cultured petri dishes in her lab. The bacteria on the dish, seen March 13, is Klebsiella ozaenae, a gram-negative bacilli in the Enterobacteriaceae family. This isolate is resistant to multiple antibiotics: penicillin, cephalosporins and macrolides.
