Biological Effects of Bacitracin as a Therapeutic Agent and Growth-Promoting Compound
Dr David Francis of South Dakota State University and director of the Center for Infectious Disease Research and Vaccinology describes an experiment in which he and co-workers found that cultivation of a wide variety of E. coli and Salmonella strains in the presence of sub-inhibitory concentrations of bacitracin favoured selection of tetracycline-sensitive organisms over those resistant to tetracycline. The paper was presented at Alpharma's Swine Enteric Health Symposium in 2008.
