Consensus tree based on Salmonella-Citrobacter core genome. Maximum likelihood phylogenetic trees were constructed from multiple alignments of concatenated core gene sequences of Salmonella and Citrobacter using RaXML. The consensus tree divided the Salmonella and Citrobacter strains into two distinct clades. The tree confirms that the false positive strains (red and green dots) belong to the genus Citrobacter. Genetic distance is defined by the scale and bootstrap values indicate percentages of 1000 replicates
