Background and Aims: Given the importance of aminoglycoside resistance in nosocomial and community infections caused by bacterial pathogenes such as Klebsiella pneumoniae (K. pneumoniae), the aim of this study was to determine the frequency of aac (6')- Ib and aac (3)- IIa, the genes encoding aminoglycoside modifying enzymes involved in aminoglycoside resistance. Material and Methods: A t...
Antimalarial drugs with the 4-aminoquinoline scaffold such as the important drugs, chloroquine (CQ) and amodiaquine (AQ), have been used to prevent and treat malaria for many years. The importance of these drugs is related to their simple usage, high efficacy, affordability, and cost-effectiveness of their synthesis. In recent years, with the spread of parasite resistance to CQ and cross-resist...
Bachground and objectives: Hospital surfaces can serve as reservoirs of potential pathogen bacteria. Staff hands are the most important source of transmission in hospital. The prevalence of β–lactamase producer bacteria in staff hands and hospital surfaces, increase antibiotic resistance nosocomial infection. The aim of this study was to survey the spread of beta-lactam resistance St...
The objective of this study was to determine the occurrence of antimicrobial resistance among Staphylococcus aureus and to estimate the presence of methicillin-resistance in S. aureus (MRSA) isolates obtained by culture and polymerase chain reaction (PCR) methods. For this purposes, 100 Iranian white and feta cheese samples collected from different suppliers were initially evaluated for the occ...
Among 155 clinical respiratory isolates of Haemophilus influenzae in Korea, 6 (3.9%) isolates had reduced levofloxacin susceptibility (MICs ≥ 0.5 μg/mL). These six isolates had no significant quinolone resistance-determining region (QRDR) mutations in gyrA, gyrB, parC, or parE. This phenomenon suggests that neither evolution nor spread of any significant QRDRs mutations in clinical isolates occ...
Multidrug resistant (MDR) bacteria are spread through the world which causes nosocomial infections, especially in Intensive Care Unit (ICU). This study aimed to investigate resistance pattern of Pseudomonas aeruginosa and Enterobacter cloacae isolated from patients in ICU. During 2011-2012, 30 isolates for each P. aeruginosa and E. cloacae were collected from patients who acquired nosocomial in...
Introduction: Due to the increasing trend of antibiotic resistance in the Enterobacteriaceae family, treatment of infections caused by these bacteria has been difficult. The aim of this study was to identify of class I and II integrons and associated gene cassettes in clinical isolates of Escherichia coli and Klebsiella pneumonia. Methods: In this cross-sectional study, of 500 strains isolat...
