Fig. 2From: Laboratory-acquired infections of Salmonella enterica serotype Typhi in South Africa: phenotypic and genotypic analysis of isolatesMolecular subtyping of Salmonella Typhi isolates. Snapshots are shown from dendrograms and phylogenetic trees of all South African isolates. a Snapshot from a dendrogram of PFGE (XbaI digestion) patterns (b) Snapshot from a phylogenetic maximum-likelihood tree drawn using SNP alignments. Note: isolate 958151 was isolated from a specimen collected on 4 June 2016 (4Â months after isolation of the case 2 isolate), so case 2 could not have been exposed to isolate 958151Back to article page
