From: Antimicrobial resistance in Antarctica: is it still a pristine environment?
Top panel: map of Antarctica showing the locations in which all the studies analysed in this review took place. If a single author investigated more than one site and clearly distinguished the results of each site, each sample site was recorded individually in Additional file 3. Markers in the sea are from cruise samplings. Bottom left panel: summary of studies conducted in the South Shetland Islands according to the types of antibiotic identified at each site; full details of studies are detailed in Additional file 4. Bottom right panel: summary of resistance found to β-lactams and aminoglycosides in Antarctica; full details of studies are detailed in Additional file 5. NB: when an antibiotic class is annotated as not being present, e.g. resistance to β-lactams not aminoglycosides, this means that the relevant study did not find resistance to aminoglycosides, rather than it being absent
