ABSTRACT
OBJECTIVES:
To investigate the molecular characteristics and epidemiology of metallo-ß-lactamase-producing Pseudomonas aeruginosa from urine of urinary tract infection patients in Hyogo Prefecture, Japan.METHODS:
Carbapenem-resistant P. aeruginosa isolated from the urine of 21 urinary tract infection patients in three general hospitals in Hyogo Prefecture (Japan) were collected between 2007 and 2014. Their antibiotic susceptibilities, metallo-ß-lactamase screening test, metallo-ß-lactamase gene sequencing, multilocus sequence typing and repetitive-sequence-based polymerase chain reaction were determined for epidemiological analyses to investigate the genetic characteristics.RESULTS:
Out of 21 isolates, 13 (61.9%) were positive for metallo-ß-lactamase. There were 11 (52.4%) isolates with IMP-1 in them, one (4.5%) isolate with IMP-7 and one (4.5%) isolate with VIM-1. Metallo-ß-lactamase-positive isolates were mainly identified as ST235, and metallo-ß-lactamase-negative isolates were STs 357, 277, 234, 439 and 639. Repetitive-sequence-based polymerase chain reaction showed metallo-ß-lactamase-positive isolates were grouped in eight clusters, and ST235 isolates with IMP-1 from three hospitals belonging to the identical group I, the other ST235 isolates with IMP-7 and VIM-1 were from two hospitals belonging to group II.CONCLUSIONS:
Metallo-ß-lactamase-positive P. aeruginosa of ST235 isolates with IPM-1 were mainly identified from the urine of urinary tract infection patients in Hyogo, Japan. A ST235 isolate with VIM-1 was found for the first time. Further investigation is necessary to follow the spread of metallo-ß-lactamase-positive isolates.Palavras-chave
