University Park, Pa. -- Penn State's Gastroenteric Disease Center (formerly E. coli Reference Center) hosts one of the largest collections of E. coli strains in America -- more than 70,000 samples of the bacteria that have been collected over the last 40 years from different host species such as humans, cows, pigs, birds and the environment. The center can conduct diagnostic tests for industry, government agencies or individuals to see if the E. coli strain in question is capable of causing disease.
Information on each strain is recorded in a database and available for determining trends in antimicrobial resistance over the years, relatedness between strains, epidemiology and molecular tracking in outbreaks, said Chobi DebRoy, director of the center, part of Penn State's College of Agricultural Sciences.
The center has tested fruits and vegetables working with the U.S. Department of Agriculture, meat from meat plants with the American Meat Institute, and water and recreation areas in collaboration with the USDA wildlife program. Another issue is safety guidelines for petting zoos and other facilities. The staff also works with other enteric bacteria such as Salmonella, Listeria and Campylobacter.
