Abstract Background The role of integrons has been shown in the horizontal transmission of antibiotic resistance genes among bacterial isolates especially Gram-negative microorganisms in clinical settings. Objectives The aim of this study was to systematically review the prevalence of class 1 integrons and antibiotic resistance in Pseudomonas aeruginosa isolates of clinical samples of Iranian patients. Methods The Web of Science, PubMed, Scopus, and Science Direct databases were searched using preferred keywords based on the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. The cross-sectional studies addressing the frequency of class 1 integrons and antibiotic‑resistance in P. aeruginosa isolates from clinical samples of Iranian patients published from 1 January 2000 until 31 December 2018 were included. Meta-analysis was performed using Comprehensive Meta-Analysis¬ (CMA) software. The random effects model was used for meta-analysis. The Cochran’s Q and I2 tests were applied for statistical analyses. Publication bias was assessed using Funnel plot and Egger’s linear regression test. Results Out of 911 studies retrieved in the initial search, 17 articles met the eligibility standards for being included in the meta-analysis. The Egger’s linear regression test indicated no publication bias (P = 0.95). The combined prevalence of class 1 integrons in P. aeruginosa isolates was obtained as 58.9% (95% CI: 46.3–70.4%). The highest rate of combined antibiotic resistance was related to Carbenicillin with a resistance rate of 79.9%. On the other side, the most effective antibiotic against P. aeruginosa was Polymyxin B with the resistance rate of 0%. The pooled prevalence of multi-drug resistant (MDR) P. aeruginosa isolates was 55% (¬95% CI: 33.8-75.3%). Conclusions Our findings indicated the high prevalence of class 1 integrons and antibiotic resistance among P. aeruginosa isolates of Iranian patients’ clinical samples. Also, the prevalence of MDR P. aeruginosa isolates was noticeable requiring prompt action.

Background: The purpose of this study was to systematically review the prevalence of class 1 integrons, antibiotic resistance pattern in Pseudomonas aeruginosa (P. aeruginosa) isolated from clinical samples other than burn samples. Methods: The Web of Science, PubMed, Scopus, and Science Direct databases were searched using keywords based on the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. The cross-sectional studies published from 1st January 2000 until 1st January 2019 were included which addressed the prevalence of class 1 integrons and antibiotic-resistance in P. aeruginosa isolated from clinical samples other than burn samples. Meta-analysis was conducted using Comprehensive Meta-Analysis (CMA) software. The random-effects model, Cochran’s Q and I2 tests were applied for statistical analyses. Results: Eight articles met the eligibility standards for including in the present meta-analysis. The combined prevalence of class 1 integrons in P. aeruginosa isolated from clinical samples other than burn samples was reported by 40% (95% CI:26.1-55.8%). The pooled prevalence of Multi-Drug Resistant (MDR) P. aeruginosa isolates was 70.1%. The highest prevalence of combined antibiotic resistance was related to carbenicillin with a resistance rate of 79.9%. In general, 6 (75%) out of the 8 included studies showed the correlation between the presence of class 1 integrons and antibiotic resistance. Conclusion: Regarding the correlation between the presence of integrons and the high antibiotic resistance reported by studies included in the present review, there is the need for preventive measures to prevent the spread of resistance by integrons and transferring to other micro-organisms

Abstract The role of integrons has been highlighted in antibiotic resistance among Pseudomonas aeruginosa isolates. Therefore, we here reviewed the prevalence of class 1 integrons and their correlations with antibiotic resistance of P. aeruginosa isolated from Iranian burn patients. This review was conducted according to the guidelines of Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). Cross-sectional and cohort studies published from January 1, 2000 until December 31, 2018 were enrolled. Meta-analysis was performed by Comprehensive Meta-Analysis (CMA) software using the random effects model, Cochran’s Q, and I2 tests. Publication bias was estimated by Funnel plot and Egger’s linear regression test. Nine out of 819 studies met the eligibility criteria. The overall combined prevalence of class 1 integrons in P. aeruginosa isolates was 69% (95% confidence interval [CI]: 50.5–83%). The highest combined resistance was reported against Cloxacillin (87.7%), followed by Carbenicillin (79.1%) and Ceftriaxone (77.3%). The combined prevalence of multidrug-resistant (MDR) isolates was 79.3% (95% CI: 31.1–97%). Also, a significant correlation was noted between the presence of class 1 integrons and antibiotic resistance in 55.5% of the included studies (P < .05). The results showed high prevalence of class 1 integrons, antibiotic resistance, and MDR strains in P. aeruginosa isolated from Iranian burn patients. Also, most of the included studies showed a significant correlation between the presence of class 1 integrons and antibiotic resistance.

The presence of integrons and antibiotic resistance genes in the genome of Pseudomonas aeruginosa pose a serious problem in the treatment and control of infections caused by this pathogen in hospitals. This study was carried to analyse the presence of class 1 integrons and some antibiotic resistance genes on selected clinical and environmental strains of Pseudomonas aeruginosa. A total of 120 strains were employed for this study.The strains were confirmed using molecular method and species-specific primers targeting the 16S ribosomal ribonucleic acid (rRNA). Polymerase chain reaction (PCR) was used to detect the presence of class 1 integrons and resistance genes using appropriate primers and conditions. The strains were analysed for the presence of the following antibiotic resistance genes - aadA, blaPSE, blaAMPC, blaIMP and tetC encoding  aminoglycosides, betalactamases, metallo-beta-lactamases (MBL) and tetracylines resistance respectively. On screening the isolates for the presence of class 1 integrons, 50/60 (83.3 %) clinical isolates and 46/60 (76.7 %) environmental isolates showed positive results (P > 0.05). In both clinical and environmental isolates, the highest occurring resistance genes were blaAMPC and tetC (encoding beta-lactamases and tetracylines respectively), while the least was observed in blaIMP (encoding metallo-beta-lactamases). In comparison, there was high significance difference (at P<0.01 significance level) in the resistance gene blaPSE between the clinical and environmental strains. The high prevalence of these resistance genes is a great threat in the treatment of Pseudomonas infections. Keywords: Pseudomonas aeruginosa, Resistance genes, Integrons, Beta-lactamases.
