BACKGROUND
RESULTS
Pseudomonas aeruginosa is a pathogen frequently found as an
agent of Hospital Acquired Infec7ons. This bacterium is very
easy to be resistant to several types of an7bio7cs through
various mechanisms. Carbapenem such as Imipenem and
Meropenem is a potensial op7on for the therapy of this
bacterium, but unfortunately P. aeruginosa has an ability in
hydrolyzing these an7bio7cs through enzyme metallo‐β‐
lactamases (MBLs). Recently, IMP and VIM, MBLs enzyme
group are reported common from various countries, but no
data is reported for these enzymes in Indonesia especially in
Bali. In fact, the resistant data of P. aeruginosa against
Carbapenem group an7bio7cs such as Meropenem and
Imipenem is quite high in Sanglah General Hospital in 2014,
which were 35% and 45%, respec7vely

OBJECTIVE
!
To detect IMP‐1 and IMP‐2 genes of MDR P. aeruginosa
isolates in Clinical Microbiology Laboratory, Sanglah General
Hospital, Denpasar Bali, which are phenotypicall resistant to
an7bio7cs, Imipenem and Meropenem using PCR.

68, 69,80 = posi7ve for IMP‐1 genes
There was no isolates posi%ve for IMP‐2 gene
CONCLUSION
All isolates were subjected to PCR for detec7on of IMP‐1 and
IMP‐2. The result showed that 9 isolates were posi7f IMP‐gene
(10.5%), but there was no isolates posi7ve for IMP‐2 gene. This
study showed the similar condi7on with the MBL gene research
studies from the other countries, especially for the gene IMP‐1 .
Detec7on and molecular characteriza7on of MBL‐producing P.
aeruginosa strains is very important for infec7on control
purposes. Currently, this study is s7ll con7nued for detec7on of
another MBL genes.
