Abstract:
Pseudomonas aeruginosa (P. aeruginosa) is a ubiquitous opportunistic organism that is hard to treat. This study aimed to investigate the association of blaVIM, blaIMP, and blaNDM prevalence with Cyclic di-GMP (c-di-GMP) in P. aeruginosa. To this end, ۲۷ clinical isolates of P. aeruginosa were obtained from different hospitals in Baghdad, Iraq. The phenotypic detection of carbapenem and biofilm assays was performed by the M۶۳ minimal medium, supplemented with glucose, magnesium sulfate. The polymerase chain reaction was utilized to detect carbapenem genes. The results showed that the isolates were highly resistant to Imipenem (۳۷%) and Meropenem (۶۳%). Imipenem (۳۷%) and Meropenem (۶۳%) demonstrated a moderate sensitivity against P. aeruginosa. The P. aeruginosa No.۵ showed high resistance to carbapenem by blaVIM+, blaIMP+, and blaNDM+, followed by a robust biofilm confirmed with c-di-GMP levels and the twitching motility ability. Upon these findings, the use of antibiotics should be restricted to severe bacterial infections to avoid the rapid emergence of new resistant isolates, which leads to the hard treatment of infection with P. aeruginosa. It is highly recommended that these findings be notified for infectious control. Future studies can investigate the link between transferable resistant genes and c-di-GMP values.
