Article Abstract

is a common opportunistic pathogen. The potential efficacy of phage therapy has attracted the attention of researchers, but efficient gene-editing tools are lacking, limiting the study of their biological properties. Here, we designed a type V CRISPR-Cas12a system for the gene editing of phages. We first evaluated the active cutting function of the CRISPR-Cas12a system and discovered that it had a higher gene-cutting efficiency than the type II CRISPR-Cas9 system in three different phages. We also demonstrated the system's ability to precisely edit genes in phages, phages, and phages. Using the aforementioned strategies, non-essential phage genes can be efficiently deleted, resulting in a reduction of up to 5,215 bp (7.05%). Our study has provided a rapid, efficient, and time-saving tool that accelerates progress in phage engineering.

Phage contamination poses a significant threat to industrial fermentation, leading to substantial economic losses. Virulent T-even type phages (T2/T4/T6) represent particularly concerning biological hazards in fermentation systems. This paper developed a novel CRISPR/Cas12a-based system integrated with recombinase polymerase amplification (RPA), enabling ultrasensitive identification of T-even type phages.

The escalating threat of antimicrobial resistance is exacerbated by delayed diagnostics and improper antibiotics use, underscoring an urgent demand for rapid, versatile AST tools to support evidence-based prescribing. In this study, we present an innovative, generalizable phenotypic AST approach by quantifying bacterial gDNA copy number variations (CNVs) following 0.5-h-brief culturing with antibiotic exposure, termed spatially encapsulated emulsions (SEE)-phAST.

Unlabelled: Drug-resistant tuberculosis (TB) is a major global public health concern. Although isoniazid is currently considered one of the most effective first-line drugs for TB treatment, its efficacy is limited by the emergence of resistance. Therefore, it is imperative to develop new methods for detecting drug-resistant TB.

The CRISPR/Cas system is a potential tool for genome editing, yet it faces challenges due to off-target activity caused by mismatches at specific positions. However, Off-target activity can be minimized by optimal design of guide RNA (gRNA) but there remains a possibility of unintended cleavage, highlighting the role of the Cas nuclease in off-target recognition and binding the target site. This study focuses on comparing the conformational dynamics and stability of Wildtype, RR, RVR, RRm and RVRm variants of AsCas12a with gRNA-DNA bound complexes.
