[Investigation of Resistance Nodulation Division (RND) Efflux Pump and OPRD Expression Levels in Antibiotic Resistance of Clinical Pseudomonas aeruginosa Isolates].

The increasing antibiotic resistance in Pseudomonas aeruginosa, responsible for both community-acquired and hospital-acquired infections, is of global significance. The primary mechanisms contributing to resistance development in P.aeruginosa include the increased activity of efflux pumps, decreased permeability of outer membrane porins and the production of carbapenemases.

Genome-Wide Screens Identify Genes Responsible for Intrinsic Boric Acid Resistance in Escherichia coli.

Boric acid (BA) has antimicrobial properties and is used to combat bacterial infections, including Enterobacteria. However, the molecular mechanisms and cellular responses to BA are still unknown. This genomics study aims to provide new information on the genes and molecular mechanisms related to the antimicrobial effect of BA in Escherichia coli.

Evaluation of the relationship between progression and SARS-CoV-2 viral load in COVID-19 cases in Ankara, Turkey.

Introduction: Patients infected with SARS-CoV-2 may present with varying clinical pictures. This study aimed to examine the relationship between viral load cycle threshold value, clinical prognosis and other laboratory parameters in initial swab samples on the day of hospitalization.

Methodology: This retrospective and cross-sectional study included 112 patients, who were diagnosed with SARS-CoV-2 via the Bio-Rad CFX96 TouchTM system.

Investigation of Viral Load Cycle Threshold Values in Patients with SARS-CoV-2 Associated Pneumonia with Real-Time PCR Method.

Introduction: In this study, we aimed investigate the relationship of SARS-CoV-2 viral load cycle threshold (Ct) values with pneumonia.

Methodology: A total of 158 patients in whom SARS-CoV-2 was confirmed in upper respiratory tract (URT) samples with molecular method and who had computed tomography (CT) of the chest, between April 2020 and June 2020 were included in this retrospective cross-sectional study.

Results: Mean age of 158 PCR positive patients was 45.
