Stereochemical Trajectories of a Two-Component Regulatory System PmrA/B in a Colistin-Resistant Acinetobacter baumannii Clinical Isolate.

Background: There is limited information on the three-dimensional (3D) prediction and modeling of the colistin resistance-associated proteins PmrA/B TCS in Acinetobacter baumannii. We aimed to evaluate the stereochemical structure and domain characterization of phosphotransferase membrane receptor A/B (PmrA/B) in an A. baumannii isolate resistant to high-level colistin, using bioinformatics tools.

Dissemination of different sequence types lineages harboring among uropathogenic in Kerman, Iran.

Objectives: is one of the most important causes of urinary tract infections (UTIs). The aim of this study was to determine antimicrobial resistance, resistance and virulence genes; phylogenetic groups and identify the epidemiologic features of uropathogenic (UPEC) isolates by multilocus sequence typing (MLST).

Materials And Methods: One hundred isolates of from inpatients with UTIs were collected in Kerman, Iran.

Detection of methicillin-resistant (MRSA) in clinical samples of patients with external ocular infection.

Background And Objectives: is the main Gram-positive bacteria isolated from patients with ocular infections. Herein, we describe the pattern of antibiotic resistance, presence of resistance genes including and the cytotoxin gene in isolates collected from patients with external ocular infection.

Materials And Methods: In this study, 8 isolates were collected from 81 patients that suffered from eye damage.
