Model diagnostics and comparisons The joint Dirichlet model with variable type transmission potential had very good convergence metrics (Rhat < 1.008). When type transmission potential terms were set to be equal, the joint Dirichlet model failed to converge (Rhat > 1), further highlighting the importance of including type transmission potential terms. Two-step inference with variable or equal type transmission potential converged adequately (Rhat < 1.04).

The transmission of Salmonella enterica within a vertically integrated poultry operation was investigated longitudinally over an 18-month period (2013–2014). Thirty six percent of all samples collected (1503 of 4219) were positive for salmonellae with seven Salmonella enterica subsp. enterica serovars, and one Salmonella enterica subsp. salamae serovar detected. Both Salmonella enterica subsp. enterica serovars Infantis and Typhimurium were detected in all locations sampled.
