Resistance to last resort drug arose in patient over 3 weeks

Researchers discovered a single nucleotide mutation in P. aeruginosa that caused rapid resistance to ceftolozane-tazobactam and partial resensitization to carbapenems and piperacilline-tazobactam. This finding may enable the use of these antibiotics in treating extremely drug-resistant P. aeruginosa cases.
