The paper develops a rules-based classifier to predict ciprofloxacin resistance in Klebsiella pneumoniae from genotype data and demonstrates its global distribution association with quinolone consumption.

The paper introduces TyphiNET, a dashboard for exploring Typhi genomics data to support public health decisions on antimicrobial resistance and vaccine implementation.

This paper reclassifies SHV β-lactamase alleles in K. pneumoniae genomes based on mutations, improving genotype-phenotype understanding and updating the Kleborate tool.

This study analyzes K. pneumoniae serotypes in India, identifying prevalent types and their geographical and resistance associations, suggesting vaccine strategies to cover >85% of strains.

The paper uses WGS to analyze 508 S. aureus isolates from India, identifying three major clones and two novel MRSA sub-lineages of CC22, with evidence of global transmission.

The paper reports the persistent circulation of third-generation cephalosporin-resistant Salmonella Typhi in Mumbai, India, linked to an IncX3 plasmid carrying resistance genes.

The paper introduces Pathogenwatch, a web tool for genomic surveillance of Klebsiella, showing it identifies drug-resistant clones and vaccine candidate O-types in genomes from low- and middle-income countries.

This study uses whole genome sequencing to analyze antimicrobial-resistant Klebsiella isolates from Nigeria, identifying known and novel lineages, including multidrug-resistant ESBL producers.

This study analyzes CRKP isolates in Colombia using WGS, identifying high-risk clones and carbapenemase genes, emphasizing the need for WGS-based surveillance.

Whole genome sequencing identified three previously unrecognized Klebsiella pneumoniae outbreaks in neonatal intensive care units in the Philippines, revealing an epidemic plasmid associated with carbapenem resistance.

This study characterizes the genomic diversity of carbapenem-resistant Klebsiella pneumoniae isolates from India, identifying high-risk clones and resistance mechanisms.

The paper uses whole genome sequencing to analyze carbapenem-resistant Acinetobacter baumannii isolates from Indian hospitals, identifying novel sequence types and clonal complexes associated with carbapenemase resistance.

The paper reconstructs the evolutionary histories of antibiotic-resistant pneumococcal lineages PMEN3 and PMEN9, showing how interspecies recombination contributes to antibiotic resistance and serotype switching.
