RESUMO
Four ST664 (serotype O:5) strains of Pseudomonas aeruginosa highly resistant to antibiotics including ceftolozane/tazobactam and ceftazidime/avibactam but susceptible to colistin, were found to harbor the rare class C ß-lactamase PAC-1 encoding gene on a chromosomally-located Tn1721-like transposon. Gene bla PAC-1 was associated with the 16S rRNA methylase determinant rmtF2, that confers pan-aminoglycoside resistance. These genotypically-related strains were isolated in repatriated patients from Mauricius and Afghanistan and close to a lineage reported in Nepal, Pakistan and India.
