AI Article Synopsis

  • This study investigates potential drug targets in a pathogenic bacterium commonly found in the gastrointestinal tract, which poses a risk of infections and has rising antibiotic resistance.
  • Using a subtractive proteomics approach, the researchers identified essential proteins and metabolic pathways linked to both the pathogen and its host to reduce side effects of new treatments.
  • The study highlights MurM, a key protein involved in bacterial cell wall synthesis, as a promising drug target and identified several lead candidates for further development to combat antibiotic resistance.

Article Abstract

is commonly found in the GI tract of humans and animals. It causes various infections, especially in hospital environments, and shows growing antibiotic resistance. This study utilized a subtractive proteomics approach to find out the potential drug targets in . Unique metabolic pathways were analysed and compared to the host to minimize adverse effects. Among twenty nine pathogenic specific and seventy three host-pathogen common pathways identified using the KEGG database, sixty seven essential proteins were found through the DEG BLAST search. PSORTB predicted that forty cytoplasmic proteins could be suitable as druggable targets. Further analysis identified fourteen proteins with virulence properties using the VFDB BLAST. Among these, seven proteins with more than ten antigenic sites were subjected to DrugBank BLAST, identifying three novel and four existing drug targets. One of the crucial drug targets, MurM, was selected due to its critical role in peptidoglycan biosynthesis. The reason for selecting MurM is crucial for addressing antibiotic resistance, disrupting bacterial cell wall synthesis, and attaining selective antimicrobial activity. MurM belongs to the mixed class with two functional domains. The possible binding site residues of MurM are Trp31, Lys35, Trp38, Arg215, and Tyr219. Virtual screening identified potential lead candidates for MurM, and four were selected based on their physiochemical, pharmacokinetic, and structural properties. This study provides valuable insights into identifying and analysing a potential drug target, the MurM protein, and its inhibitors in V583.

Urinary tract infections (UTIs) often prompt empiric outpatient antibiotic prescriptions, risking mismatches. This study evaluates the impact of "UTI Smart-Set" (UTIS), an AI-driven decision-support tool, on prescribing patterns and mismatches in a large outpatient organization. UTIS integrates machine learning forecasts of antibiotic resistance, patient data, and guidelines into a user-friendly order set for UTI management.

Introduction: The escalating resistance of microorganisms to antimicrobials poses a significant public health threat. Strategies that use biomarkers to guide antimicrobial therapy-most notably Procalcitonin (PCT) and C-reactive protein (CRP)-show promise in safely reducing patient antibiotic exposure. While CRP is less studied, it offers advantages such as lower cost and broader availability compared with PCT.

Objectives: Emerging human pathogens of animal origin have become an increasing public health concern in recent years. The aim of this study was to investigate the transmission of group B streptococcus (GBS) clonal complex (CC) 61 strains in the southern Chinese population and analyze their genetic characteristics.

Methods: Whole-genome sequencing was performed on 693 clinical isolates of GBS collected from southern China between 2016 and 2021, and the prevalence of human CC61 isolates was investigated by genomic epidemiology.
