Phylogenetic tree and presence/absence matrix depicting virulence and acquired resistance genes. The strain names on the tree branches are coloured representing the prevalent clones (>4 isolates, red), the low prevalence clones (2–3 isolates, blue) and the sporadic isolates (single isolates, green). The coloured squares in the first column represent the emm-type/ST combinations, specified on the left side. Colours of the squares in the second column represent the time period. The squares in the third column indicate the sample in which the strain was isolated. The blue squares represent a presence/absence matrix of virulence factors related to adherence, invasiveness, immune system evasion and toxin production (represented in different shades of blue). After the virulence factors, the coloured-squares column represents the MGE in which resistance genes were found (if there are variations from what is described, there is a dot inside the square). The purple squares represent the presence of acquired resistance determinants of macrolides and/or lincosamides [erm(B), erm(TR), mef(A), msr(D) and lnu(C)], tetracyclines [tet(M), tet(O), tet(T) and tet(L)], aminoglycosides [ant(6)-Ia and aph(3′)-III] and chloramphenicol [cat(pC194)]. This figure appears in colour in the online version of JAC and in black and white in the print version of JAC.
