Antibiotic resistance pattern of Klebsiella pneumoniae in obtained samples from Ziaee Hospital of Ardakan, Yazd, Iran during 2016 to 2017

Abstract

Background: In recent years, due to the inappropriate use of antibiotics, drug resistance has increased in gram negative bacilli, including Klebsiella pneumoniae. Drug resistance is associated with an increase in mortality and therapeutic costs. Therefore, determination of an antibiotic resistance pattern for choosing the appropriate treatment for infections caused by this bacterium seems necessary. This study was conducted to determine the antibiotic resistance pattern of Klebsiella pneumoniae species isolated from patients referring to Ziaee Hospital in Ardakan in 2016-2017. Materials and Methods: For this descriptive-analytic study, all positive cultures of Klebsiella pneumoniae in patients referred to Ziaee Hospital in Ardakan during 2016 to 2017, were evaluated. Antibiotic resistance patterns of the samples were determined by the standard method of propagation of the disk from 12 different antibiotics and data analyzed by SPSS 21 software. Results and discussions: The results of this study, which were performed on 75 samples, showed that 22 (29.3%) were male and 53 (70.7%) were female. Klebsiella's resistance to clarithromycin was 100%, but was 100% susceptible to amikacin. The percentage of Klebsiella's resistance to ampicillin was 78.3%, cefalotin 75%, cotrimoxazole 43.9%, ceftriaxone 32%, ciprofloxacin 30.9%, cefotaxime 24%, and ampicillin 20%. The highest sensitivity of Klebsiella pneumoniae for antibiotics was 100% for amikacin, 82.8% for meropenem and 82% for cefepime. Due to the high prevalence of resistance in Klebsiella samples, there is a need for strict measures in the administration of antibiotics. Antibiotic resistance can also be reduced by choosing the appropriate antibiotic for treatment and by taking antibiotic susceptibility tests.
