Fig. 2From: Tylosin exposure reduces the susceptibility of Salmonella Typhimurium to florfenicol and tetracyclineGeneration of free radicals (measured in terms of optical density) in S. Typhimurium before and after exposure to decreasing concentration of tylosin (initial concentration of 3 μg/mL) in the in vitro dynamic assay. Data presented as mean ± SD. **P < 0.01 compared to the non-exposed S. TyphimuriumBack to article page
