Antibiotic Resistance Pattern

Background and Aims: Acinetobacter baumannii is an important multidrug-resistant opportunistic pathogen frequently causing various nosocomial infections and is a serious threat to burn patients. These infections are usually caused by the outbreak strains. The aim of this study was to show antibiotic resistance pattern and molecular typing of A.baumannii genes isolates collected from burn patients and also distribution of different types of burn patients. Materials and Methods: In this study, 307 different strains were detected. Totally 100 A.baumannii strain was selected in burn center of Isfahan hospital. Antibiotic resistance pattern was determined by disk diffusion method (Kirby Bauer). The presence of genes coding in antibiotic resistance were analyzed by using M-PCR method. The standard strains of Escherichia coli ATCC 25922 and A. baumannii ATCC 19606 were used as negative and positive controls. Results: The antibiotic resistance pattern for A.baumannii showed high resistance for ciprofloxacin, ceftazidime, and tetracycline with frequency of 82.5%, 75.3%, 72%, respectively. Moreover, the most sensitive antibiotics were chloramphenicol, and nitrofurantoin with the resistance frequency of 3.9% and 2.8%. CITM (91.1%) was the highest detected gene. Conclusions: High prevalence of antibiotic resistance pattern among A.baumannii isolated from burn center hospitals indicates the important role of multidrug resistant isolates.

Antibiotic Resistance Pattern

Background: Today, drug-resistant strains of Acinetobacter baumannii are one of the opportunistic pathogens in the world. This study aimed to determine the antibiotic resistance pattern of clinical isolates of A. baumannii in Khorramabad hospitals (i.e., Shohaday Ashayer-Shahid Rahimi), Khorramabad, Iran. Materials and Methods: This cross-sectional study was conducted on the clinical samples collected from patients hospitalized in the different wards of Khorramabad hospitals in 2015-16 and 2017-18. The clinical samples were identified as A. baumannii by microbiological culture and biochemical tests then confirmed by polymerase chain reaction. The susceptibility test of bacterial isolates to antibiotics was performed and the obtained data were analyzed by SPSS software (version 22) using the Chi-square test. Results: According to the results of the antibiogram, among the 94 isolates of A. baumannii collected from the patients admitted to Khorramabad hospitals, 50%, 41.49%, and 8.51% of isolates were multiple-drug resistant, extensively drug-resistant, and non-multidrug resistance, respectively. Conclusion: Due to the sensitivity of A. baumannii to polymyxin B and minocycline antibiotics, these antibiotics can be used, especially as a combination therapy, in the treatment of infections caused by this bacterium. Since the rate of multidrug resistance in Khorramabad hospitals was found to be 91.49%, it is necessary to pay attention to the criteria for controlling nosocomial infections.

Background: Nowadays, the resistance of pathogenic bacteria to antibiotics has become a global problem. Acinetobacter baumannii is an important opportunistic nosocomial pathogen. Acinetobacter baumannii plays a significant role in antibiotic resistance. Objectives: The purpose of this study was to investigate the prevalence of the blaOXA-51, blaNDM, blaVIM, blaPER, blaVEB, blaCTX-M, tetA and tetB genes and antibiotic resistance pattern of A. baumannii isolated from hospitals in Tabriz city, Iran. Methods: This study was descriptive cross-sectional research, performed on 129 isolates of Acinetobacter from different clinical specimens. The Isolates were identified using standard laboratory methods and culture in selective mediums. The antibiotic resistance pattern of isolates was also determined by the Kirby-Bauer disk diffusion susceptibility test. Phenotypic and genotypic detection of blaOXA-51, blaNDM, blaVIM, blaPER, blaVEB, blaCTX-M, tetA and tetB genes in the isolates was carried out by a combined disk test (CDT) and polymerase chain reaction (PCR), respectively. Results: The highest resistance of isolates was determined to cefotaxime (100%) and ceftazidime (100%). The results of CDT showed that 14 (12.96%) isolates could produce extended-spectrum Beta-lactamases (ESBLs). However, the PCR results blaOXA-51, blaNDM, blaVIM, blaPER, blaVEB, blaCTX-M, tetA and tetB genes showed that these genes were in 100%, 18.51%, 16.66%, 32.40%, 16.66%, 31.48%, 32.40% and 21.29% of isolates, respectively. Conclusions: Due to the high prevalence of antimicrobial resistance in strains, rapid and timely detection of antibiotic-resistant A. baumannii strains is necessary for the selection of an appropriate therapeutic approach and prevention of their prevalence.
