Virulence factors among MBL and Non MBL producing urinary isolates of Pseudomonas aeruginosa
Dr. KK Patel, Dr. Sarita Patel
The study was done to detect various virulence factors of urinary isolates ofPseudomonas aeruginosawith specialreference to MBL producing strains and to find out its significant association with the virulence factors. This study was done in a tertiary care teaching hospital in Bilaspur, which included 100 urinaryisolates of Pseudomonas aeruginosa. All isolates subjected to routine antibiotic susceptibility testing by Kirby Bauer Disc Diffusion method and screened for Metallo β- lactamase (MBL) by Imipenem-EDTA disc method. Phenotypic detection of virulence factors like phospholipase, hemolysin, gelatinase and DNAse were done for the same. Out of 100 isolates ofPseudomonas aeruginosa,26% were MBL producers and 74% were non MBL producers byImipenem-EDTA disc method. Virulence factors like hemolysin, gelatinase, phospholipase and DNAse were shown in 88%, 78%, 76% and 50% respectively. The association with the production of Virulence factors and MBL production were found to be statistically significant only in case of DNAse production. This study concluded thatP. aeruginosais a pathogen able to accumulate various virulence factors which are oftenaccompanied by multidrug resistance and pan-resistance, making the treatment of infections difficult for the clinicians.
