  1. Isolates retrieved from previous sampling campaigns in 2017 and 2018 are indicated in italics5. All isolates were fully susceptible to ticarcillin, ticarcillin-clavulanate, piperacillin, piperacillin-tazobactam, ceftazidime, cefepime, aztreonam, imipenem, meropenem, gentamicin, tobramycin, amikacin, and ciprofloxacin. The ID of the isolates consists of the concatenation of wPA (water P. aeruginosa), the three initials of the city, and the number of the isolate.
