Distribution of pathogenicity island markers and virulence factors in new phylogenetic groups of uropathogenic Escherichia coli isolates.

The present study was aimed at investigating the relationship between the new Clermont's phylogenetic groups, virulence factors, and pathogenicity island markers (PAIs) among uropathogenic Escherichia coli (UPEC) in Iran. This cross-sectional study was carried out on 140 UPEC isolates collected from patients with urinary tract infections in Bushehr, Iran. All isolates were subjected to phylogenetic typing using a new quadruplex-PCR method.

Modulation of virulence in Acinetobacter baumannii cells surviving photodynamic treatment with toluidine blue.

Introduction: Widespread resistance to antimicrobial agents has led to a dearth of therapeutic choices in treating Acinetobacter baumannii infections, leading to new strategies for treatment being needed. We evaluated the effects of photodynamic therapy (PDT) as an alternative antimicrobial modality on the virulence features of cell-surviving PDT.

Materials And Methods: To determine the sublethal PDT (sPDT), a colistin-resistant, extensively drug-resistant A.

Antimicrobial resistance profiles and genetic elements involved in carbapenem resistance in Acinetobacter baumannii isolates from a referral hospital in Southern Iran.

In this study, antimicrobial resistance patterns, carbapenemase production, carbapenem-hydrolysing class D OXA-type β-lactamase (CHDL)-encoding genes and ISAba insertion elements were characterised in Acinetobacter baumannii isolates from Southern Iran. A total of 85 A. baumannii isolates from patients in a tertiary care hospital were isolated.

Antimicrobial Resistance of Acinetobacter baumannii to Imipenem in Iran: A Systematic Review and Meta-Analysis.

Imipenem-resistant multi-drug resistant (IR-MDR) Acinetobacter baumannii has been emerged as a morbidity successful nosocomial pathogen throughout the world.To address imipenem being yet the most effective antimicrobial agent against A. baumannii to control outbreaks and treat patients, a systematic review and meta-analysis was performed to evaluate the prevalence of IR-MDR A.

Wide distribution of carbapenem resistant Acinetobacter baumannii in burns patients in Iran.

Antimicrobial resistance in carbapenem non-susceptible Acinetobacter baumannii (CNSAb) is a major public health concern globally. This study determined the antibiotic resistance and molecular epidemiology of CNSAb isolates from a referral burn center in Tehran, Iran. Sixty-nine CNSAb isolates were tested for susceptibility to antimicrobial agents using the E test methodology.
