Rep-PCR based molecular typing and percentage of similarity within Phytobacter diazotrophicus outbreak isolates and outliers. Location: H1 to H7- hospitals numbered sequentially; I1-I2 – industries 1 and 2, respectively; MG – Minas Gerais State, PR – Paraná State; CC- capital city; CS – country-side. Source: ANS – ankle secretion; BSI – blood isolates; TPN – total parenteral nutrition; RSW – rectal swab. Shaded area: isolates recovered from the outbreak. The couloured boxes states the percentage of similarity between the two strains. The red boxes indicate higher similarity (above 95%) between strains meaning isolates are clonal. The orange boxes indicate high similarities (90–95%) meaning isolates are related –i.e: belong to the same clonal group. Yellow boxes indicate intermediate similarities (70–80%). The grey boxes indicate similarity is low (50–70%)
