Overview

Niyaz Ahmed is affiliated with the University of Hyderabad in India. Their research spans multiple areas within biochemistry, genetics, molecular biology, and medicine, with a significant focus on antibiotic resistance, bacterial pathogens, and infectious diseases. Over the course of their career, they have contributed extensively to both primary fields and specialized subfields such as endocrinology, molecular medicine, surgery, food science, and immunology.

Their scientific inquiry addresses key topics including:

  • Antibiotic Resistance in Bacteria
  • Vibrio bacteria research studies
  • Escherichia coli research studies
  • Salmonella and Campylobacter epidemiology
  • Aquaculture disease management and microbiota
  • Helicobacter pylori-related gastroenterology studies
  • Veterinary medicine and infectious diseases

Among Niyaz Ahmed's recent published works are:

  • Extended-Spectrum Beta-Lactamase-Producing Escherichia coli in Drinking Water Samples From a Forcibly Displaced, Densely Populated Community Setting in Bangladesh, 2020, published in Frontiers in Public Health
  • Genome Dynamics of Vibrio cholerae Isolates Linked to Seasonal Outbreaks of Cholera in Dhaka, Bangladesh, 2020, published in mBio
  • Colistin-resistant Escherichia coli carrying mcr-1 in food, water, hand rinse, and healthy human gut in Bangladesh, 2020, published in Gut Pathogens
  • Whole-Genome Analysis of Clinical Vibrio cholerae O1 in Kolkata, India, and Dhaka, Bangladesh, Reveals Two Lineages of Circulating Strains, Indicating Variation in Genomic Attributes, 2020, published in mBio
  • Genomic insights into virulence, antimicrobial resistance, and adaptation acumen of Escherichia coli isolated from an urban environment, 2024, published in mBio

The scientist frequently collaborates with colleagues including Munirul Alam, Shamsul Qumar, John D. Clemens, Suresh Kumar Mendem, and Bindu Ambaru. These collaborations have resulted in multiple joint publications reflecting a shared research interest in bacterial genomics and infectious disease epidemiology.

Common venues for their research publications include:

  • Helicobacter
  • mBio
  • Faculty Opinions - Post-Publication Peer Review of the Biomedical Literature
  • Research Journal of Medical Sciences
  • Gut Pathogens

Niyaz Ahmed's scholarly output incorporates a broad spectrum of studies from molecular and microbial biology to clinical and epidemiological investigations. The emphasis on multidrug resistance and bacterial pathogen genomics highlights their engagement with public health challenges in densely populated and resource-limited settings.
