Background: Standardising procedures is the best way to harmonise and strengthen the quality of laboratory-based antimicrobial resistance surveillance. Since 2018, Burkina Faso has developed and disseminated the national manual of procedures for performing antibiotic susceptibility tests in sentinel laboratories within its national antimicrobial resistance surveillance network.
Objective: Our study aimed to assess these sentinel laboratories' compliance with good practices for antibiotics susceptibility tests.
Methods: Four teams evaluated the antimicrobial resistance sentinel sites laboratories throughout Burkina Faso from 19 to 28 September 2022. Eighteen out of 19 sentinel laboratories were evaluated. A four-member technical committee designed and validated the evaluation tool composed of three Microsoft Excel sheets. The evaluation emphasised quality controls for culture media, antibiotic discs and compliance with antimicrobial susceptibility testing procedures by the laboratories. Excel software was used for data recording and graphs and table design. The free R software version 4.2.0 was used for descriptive statistics. An overall score below 80% was considered noncompliance.
Results: Most (83.33%) of the sentinel laboratories conducted at least one quality control activity for culture media, and 66.67% conducted at least one quality control activity for antibiotic discs. Over three-quarters (76.47%) of the laboratories were more than 80% compliant with the modified Kirby Bauer antimicrobial susceptibility testing method.
Conclusion: The evaluation revealed the noncompliance of sentinel laboratories with the national procedure manual, particularly in the quality control component.
What This Study Adds: This study has provided baseline data on the sentinel laboratories' compliance with the national antimicrobial susceptibility testing procedures manual, particularly in areas performing quality control checks or meeting quality indicators for culture media and antibiotic discs.

Introduction: Murepavadin is an antimicrobial peptide (AMP) in clinical development that selectively targets LptD and whose resistance profile remains unknown. We aimed to explore genomic modifications and consequences underlying murepavadin and/or colistin susceptibility.
Methods: To define genomic mechanisms underlying resistance, we performed two approaches: 1) a genome-wide association study (GWAS) in a clinical collection (n=496), considering >0.

Ceftazidime-avibactam (CZA) is one of the effective antibiotics used for the treatment of carbapenem-resistant (CRKP) infections, but its resistance rate has increased recently. Previous studies have focused on the mechanisms of CZA resistance, while its heteroresistance in CRKP remains poorly understood. This study aimed to investigate the characteristics and mechanisms of CZA heteroresistance in CRKP isolates.

Antiviral drugs are essential medications to save the lives of infected people. However, they are under constant threat to become ineffective as viruses evolve quickly. Studying the development of resistance is therefore paramount to understand the impact of mutations on pharmacological treatment and to make informed decisions.

The emergence of resistance in represents a significant global health challenge, particularly due to the hurdle of effectively penetrating biofilms with antimicrobials. Moreover, the rise of antibiotic-resistant pathogens has driven the urgent need for developing innovative therapeutic approaches to overcome antibiotic resistance. Antibacterial phototherapy strategies have shown great potential for combating pathogens due to their broad-spectrum antimicrobial activity, spatiotemporal controllability, and relatively low rate of resistance emergence.

Bacteria biofilm infection seriously challenges clinical drug therapy. Nitric oxide (NO) was reported to disperse biofilm, eliminate bacteria resistance and kill bacteria. In this study, on the basis of membrane targeting of α-mangostin (α-MG) and the dispersion effect of NO on bacteria biofilms, we designed and synthesized 30 NO donors that α-MG was conjugated with a nitrobenzene or a nitrate and other four representative reference derivatives.
