Antibiogram of ESBL and MBL producing Pseudomonas aeruginosa among the population of Hazara division, KPK, Pakistan
Abstract
OBJECTIVE: To investigate the frequency rate and sensitivity pattern of extended-spectrum beta-lactamase and metallobeta- lactamase producing Pseudomonas aeruginosa isolated from major hospitals.
METHODS: The cross-sectional study was conducted in the Microbiology section of the Pathology Department of Ayub Medical College, Abbottabad, Pakistan, from September 2017 to April 2018, and comprised clinical samples collected from different medical wards of major hospitals in the study area. For the selective growth of Pseudomonas aeruginosa, Cetrimide agar was used, and different antibiotics were evaluated for the sensitivity pattern following Kirby-Bauer diffusion method. Pseudomonas aeruginosa producing extended-spectrum beta lactamase and metallo-beta-lactamase were identified through double disk synergy test and imipenem ethylenediaminetetraacetic acid tests respectively. Patient's demographic and medical history was noted on a proforma. Data was analysed using SPSS 22.0.
RESULTS: Of the 242 samples screened, 46 (19%) were positive for Pseudomonas aeruginosa. These samples were highly sensitive to levofloxacin, amikacin, imipenem, meropenem and ciprofloxacin (p<0.05). Of the positive cases, 11 (23.91%) were detected for extended-spectrum beta-lactamase production, while 3 (6.52%) samples were detected for metallo-beta-lactamase production.
CONCLUSIONS: Pseudomonas aeruginosa samples were widely resistant to most antibiotics, but were sensitive for some antibiotics which may…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
