Enumeration of Salmonella in feces using most probable number (MPN) method. Fecal samples were collected from birds orally infected with 1 × 109 CFU of Salmonella Typhimurium (Black line) or a combination of both Salmonella Typhimurium + Salmonella Mbandaka (5 × 108 CFU of each serovar) (Red line) on day 1 and weeks 1, 2, 4, 6, 8, 10, 12, 14 and 16 pi. Data is presented as mean MPN/gram feces ± standard error of the mean. Bacterial shedding in both infection groups varied significantly over the course of the experiment (p < 0.01). At week 6 pi, bacterial shedding was significantly higher in birds infected with only Salmonella Typhimurium group (*p < 0.05).
