Multidrug-resistant (MDR) Salmonella enterica serovar Heidelberg (S. Heidelberg) tissue colonization in turkeys. At 3 weeks of age, individually housed turkeys were inoculated with 10⁸ (n = 8) or 10¹⁰ (n = 7) CFU of MDR S. Heidelberg. At day 7 following Salmonella inoculation, four turkeys from each group were euthanized, and the remaining turkeys were euthanized at 14 dpi. Tissues (crop, spleen, small intestine, cecum, and cloaca) were harvested following euthanasia for quantitative and qualitative bacteriology to determine tissue colonization by MDR S. Heidelberg. Error bars indicate SEM.
