TL;DR: The prevalence of NDM-1, in multidrug-resistant Enterobacteriaceae in India, Pakistan, and the UK is investigated, and co-ordinated international surveillance is needed.
Journal ArticleDOI
Coexistence of blaOXA-23 with blaNDM-1 and armA in clinical isolates of Acinetobacter baumannii from India.
TL;DR: Susceptibility testing showed increased MICs of carbapenems and an unusual phenotype of broad-spectrum high-level resistance to aminoglycosides, including amikacin, gentamicin, netilmicin and tobramycin (MICs), with susceptibility to tigecycline (MIC1⁄40.5–1 mg/L).
Journal ArticleDOI
Distribution and Relationships of Antimicrobial Resistance Determinants among Extended-Spectrum-Cephalosporin-Resistant or Carbapenem-Resistant Escherichia coli Isolates from Rivers and Sewage Treatment Plants in India.

TL;DR: Comparison of the DNA sequences of the blaNDM-positive plasmids detected in this study with known sequences of related plasids suggested that various mutation events facilitated the evolution of the plasmid and that plasmIDS with similar genetic backgrounds have widely disseminated in India.
Journal ArticleDOI

TL;DR: The results support the recent view that gram negative organisms, depending on the geographical location, may be predominant in DFIs.
Journal ArticleDOI
Changing trends in antimicrobial resistance of Salmonella enterica serovar typhi and salmonella enterica serovar paratyphi A in Chennai.
TL;DR: The study indicates reemergence of chloramphenicol-susceptible Salmonella enterica serovar typhi and paratyphi A isolates, a significant decline in MDR strains and high resistance to nalidixic acid.
