Fig. 1
Phylum-level bacterial composition of the microbiota in three sections of the gastrointestinal tract of the diarrhoeic wild boar (WB) from Hungary analysed in this work in comparison with those established earlier for the domestic pig (DP) by a meta-analysis (13)
Fig. 2
GrapeTree diagram generated in EnteroBase based on seven-gene MLST profiles of 104 E. coli strains isolated in Europe from wild boars and domestic pigs (2, 28, 29). Countries of origin (and number of strains): Denmark (48), Hungary (8), Czech Republic (7), Spain (7), Ireland (6), Luxembourg (5), Italy (4), Switzerland (3), United Kingdom (3), Croatia (2), France (2), Germany (2), Portugal (2), Austria (1), Belgium (1), Bulgaria (1), Netherlands (1), and Sweden (1). Dark blue, light blue, and orange indicate E. coli isolates of domestic pig, wild boar, and food origin, respectively. Numbers stand for sequence types by the Achtman seven-gene MLST scheme (28). The node size in the GrapeTree diagram is proportional to the number of bacterial strains with the same sequence type (ST), and the length of edges are proportional to inter-node genetic distances (29). ST388 determined for the E. coli O112ab:H2 strain characterised in this work is marked by an asterisk (*)
Fig. 3
Immediate genetic environment of the tetracycline resistance determinants identified from the gut microbiome of free-living wild boars in Hungary. Schematic diagrams of metagenomic contigs for the tetQ (A), tetW (B), and tetO genes (C), respectively. Abbreviations for selected genes: traG – conjugal transfer protein TraG; tnp – transposase; mobC – mobilisation protein MobC; tnpV – transposon-encoded protein TnpV; and ctp – conjugal transfer protein
