Sampling points of 27 EU-bathing sites (three per state) collected during the summer of 2017. Green dots represent bathing sites negative for antibiotic-resistant bacteria; red dots represent bathing sites positive for antibiotic-resistant bacteria.
Abbildung 1. Probenahmestellen der 27 EU-Badestellen (drei Badestellen pro Bundesland), die in der Badesaison 2017 beprobt wurden. Grüne Punkte: Badestellen die frei von antibiotikaresistenten Bakterien waren, rote Punkte: Badestellen in denen antibiotikaresistenten Bakterien nachgewiesen wurden.
