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 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.

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.

Background. Antibiotic resistance is a global challenge in the public health sector and also a major challenge in Ethiopia. It is truly difficult to report bacterial antibiotic resistance pattern in Ethiopia due to the absence of a review which is done comprehensively. The aim of this systematic review was to provide an overview of the works of literature on the antibiotic resistance pattern of the specific bacterial isolates that can be obtained from different clinical samples in the context of Ethiopia. Materials and Methods. A web-based search using PubMed, Google Scholar, Hinari, Sci Hub, Scopus and the Directory of Open Access Journals was conducted from April to May 2018 for published studies without restriction in the year of publication. Works of literature potentially relevant to the study were identified by Boolean search technique using various keywords: Bacterial infection, antimicrobial resistance, antibiotic resistance, drug resistance, drug susceptibility, anti-bacterial resistance, Ethiopia. Study that perform susceptibility test from animal or healthy source using <10 isolates and methods other than prospective cross-sectional were excluded. Results. The database search delivered a total of 3459 studies. After amendment for duplicates and inclusion and exclusion criteria, 39 articles were found suitable for the systematic review. All studies were prospective cross-sectional in nature. The review encompasses 12 gram-positive and 15 gram-negative bacteria with their resistance pattern for around 12 antibiotics. It covers most of the regions which are found in Ethiopia. The resistance pattern of the isolates ranged from 0% up to 100%. The overall resistance of M. tuberculosis for antituberculosis drugs ranges from 0% up to 32.6%. The percentage of resistance increases among previously treated tuberculosis cases. Neisseria gonorrhea, S. typhimurium, S. Virchow, Group A Streptococci (GAS), and Group B Streptococci (GBS) were highly susceptible for most of the tested antibiotics. Methicillin-Resistant Staphylococcus aureus was highly resistant to most of the antibiotics with a slightly increased susceptibility to gentamycin. Conclusions. Total bacterial isolates obtained from a different source of sample and geographic areas were 28, including M. tuberculosis. Majority of the bacterial isolates were resistant to commonly used antibiotics. A continuous monitoring and studies on the multidrug-resistant bacterial isolates are important measures.

To determine the resistance pattern of bacterial pathogens involved in infections of the patients aged between 18-64 years, admitted in a ICU from a 1518-bed university-affiliated hospital. A retrospective study of bacterial pathogens was carried out on 351 patients aged between 18-64 years admitted to the ICU, from January to December 2017. In this study there were analysed 469 samples from 351 patients (18-64 years). A total of 566 bacterial isolates were obtained, of which 120 strains of Klebsiella spp. (35.39%%), followed by Nonfermenting Gram negative bacilli, other than Pseudomonas and Acinetobacter (NFB) (75- 22.12%), Acinetobacter spp. (53 - 15.63%), Pseudomonas aeruginosa and Proteus (51 - 15.04%), and Escherichia coli (49 - 14.45%). The most common isolates were from respiratory tract (394 isolates � 69.61%). High rates of MDR were found for Pseudomonas aeruginosa (64.70%), MRSA (62.65%) and Klebsiella spp. (53.33%), while almost all of the isolated NFB strains were MDR (97.33%). There was statistic difference between the drug resistance rate of Klebsiella and E. coli strains to ceftazidime and ceftriaxone (p[0.001), cefuroxime (p[0.01) and to cefepime (p[0.01). The study revealed an alarming pattern of antibiotic resistance in the majority of ICU isolates.
