Detection of extended-spectrum beta-lactamase (ESBL) production by disc diffusion method among Pseudomonas species from various clinical samples
Aim/Objectives: This study was aimed to detect extended-spectrum beta-lactamase (ESBL) producing Pseudomonas species isolated from various clinical samples by phenotypic methods with their susceptibility testing. Materials and Methods: Hundred Pseudomonas isolates were taken from various clinical sa...

Materials and Methods: Hundred Pseudomonas isolates were taken from various clinical samples of patients attending outpatient department (OPD) and inpatient department (IPD). Antimicrobial susceptibility test and ESBL detection were assessed using CLSI guidelines on Mueller Hinton agar. Results: Out of 100 Pseudomonas isolates, 46 isolates were from female and 54 were from male patients. More cases of pseudomonal infection were in the age group between 46 and 60 years (34%), and 59% of Pseudomonas species were isolated from patients belongs to urban areas and the rest 41% were from rural. The isolates collected from OPD were 61% and rest 39% from IPD. Pseudomonas species showed maximum resistance to cephalosporin group of antibiotics and showed least resistance to imipenem, and showed 100% susceptibility to colistin. ESBL production was detected in 42% of total isolates. Conclusion: The present study highlights that the Pseudomonas species remains an important cause of nosocomial infections. ESBL producing Pseudomonas species continue to be an important organism causing life-threatening infections. Multidrug resistance was seen in most of the strains. Resistance is developing even to combination of ceftazidime clavulanic acid. Resistance is developing to last resort of antibiotic, i.e. imipenem also. This gives the alarming signal for the future, making the therapeutic options more difficult. Strict infection control measures are to be taken to contain this so-called water and soil organisms as Pseudomonas.http://www.jfmpc.com/article.asp?issn=2249-4863;year=2020;volume=9;issue=2;spage=683;epage=693;aulast=Kothariantimicrobialß-lactamases (esbls)pseudomonal infectionsusceptibility test |
