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.

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: Osteomyelitis is a common cause of morbidity in developing countries. Its treatment comprises of surgical debridement of all necrotic bone and soft tissue along with use of appropriate antimicrobial therapy. Treatment is becoming increasingly troublesome due to rise in drug resistant isolates in osteomyelitis cases. The present study was done to determine the antibiotic resistance pattern among aerobic bacterial isolates from osteomyelitis cases.Methods: 125 samples from osteomyelitis cases were aerobically cultured and isolates from culture positives were identified by standard procedures. Antimicrobial susceptibility testing was done by Kirby Bauer disk diffusion method. Staphylococcal isolates were screened for methicillin resistance and Gram negative bacilli were screened and confirmed for ESBL, AmpC and MBL production.Results: Out of 125 samples cultured, 20 were culture negative and 105 were culture positive giving rise to 120 isolates (58 Gram positive and 62 Gram negative organisms). The prevalence of methicillin resistant staphylococcal (MRS) isolates, ESBL, AmpC and MBL producers was found to be 43.1%, 51.6%, 24.2% and 14.5% respectively. All the resistant isolates were multidrug resistant, with MRS being 100% sensitive only to vancomycin, linezolid and teicoplanin, ESBL and AmpC producers being 100% sensitive only to imipenem and colistin, and MBL producers being 100% sensitive only to colistin.Conclusions: Antibiotic therapy on the basis of antibiotic susceptibility pattern helps the clinician to choose appropriate drugs leading to successful treatment and prevention of emergence and dissemination of drug resistant isolates.
