Amrita, Ramanath Karicheri, Dhananjay Kumar Pandey

Background:The present study was undertaken to detect the prevalence of the blaNDM-1 metallo beta lactamases (MBLs) in the isolates of Pseudomonas aeruginosa, which were recovered from various clinical samples from hospitalized patients in a tertiary care centre in Indore, India.Methods:A total of 200 isolates of P. aeruginosa which were obtained from various clinical samples were subjected to antibiotic susceptibility testing by the disc-diffusion method and MIC detection by the Etest method against imipenem, meropenem, piperacillin, tobramycin, ceftazidime, tigecycline and colistin. The presence of blaNDM-1 was detected by PCR.Result:In the present study, four isolates of P. aeruginosa, which carried the blaNDM-1 gene, were resistant to imipenem and meropenem. These blaNDM-1 carrying isolates remained susceptible to colistin.Conclusion:Emergence of the P. aeruginosa carrying NDM-1gene, which exhibited resistance to imipenem and meropenem, is a threat in the treatment of Pseudomonas infectionss.
