Multidrug resistance in gram-negative pathogens isolated from patients with chronic kidney diseases and renal transplant

Multidrug resistance (MDR) in gram-negative pathogens is the emerging threat to clinicians. The current study was designed to determine the prevalence and pattern of multidrug resistance in gram-negative clinical isolates. It was conducted at the COMSATS Institute of Information Technology, Islamabad, Pakistan, from June to October 2014. Of the 8, 300 samples collected, 729(8.8%) clinically important gram-negative pathogens were retrieved. These pathogens were subjected to phenotypic and biochemical detection and were further processed for multidrug resistance pattern. It was observed that gram-negative pathogens were simultaneously resistant to many antibiotics. The prevalence of extended spectrum β-lactamase phenomenon was 220(100%) in Klebsiella pneumoniae, 195(75%) in Escherichia coli. Resistance to carbapenem was 174(79%) in Klebsiella pneumoniae and 14(5.4%) in Escherichia coli. Resistance against fluoroquinolones also displayed an escalating trend. The current study found that resistance against antibiotics was displaying a drastic increase in chronic renal patients.
