Dr. Sulagna Basu

Sulagna Basu is a Scientist at the National Institute of Cholera and Enteric Diseases, Kolkata. She joined the Institute in 2006. Her current research focuses on the colonization of the neonatal gut with Gram negative bacilli and bacterial resistance to antimicrobial agents in neonatal infections. Her laboratory has identified some of the currently widely disseminated antibiotic resistance determinants in bacteria causing neonatal infections.

Sulagna Basu graduated from the University of Calcutta with B.Sc. in Chemistry. She earned her M.Sc. from the Department of Biochemistry, University of Calcutta. Dr. Basu received her Ph.D in 2003 from The Post Graduate Institute of Medical Education and Research, Chandigarh . During this period her research revolved around the purification and characterization of a lectin from Enteroaggregative Escherichia coli . She received the ACBICON 2003 award for the work on Enteroaggregative E.coli.

Research Experience

Dr. Basu received her Ph.D. in 2003 from The Post Graduate Institute of Medical Education and Research, Chandigarh for her thesis involving the isolation and characterization of a biologically active lectin from enteroaggregative E.coli. She was a Senior Demonstrator at the Institute from 2003-2005. During this period she studied the plasmid mediated virulence factors of enteroaggregative E.coli and their role in the disease process.

Sulagna Basu joined National Institute of Cholera and Enteric Diseases, Kolkata as a Scientist in 2006. Her current research focuses on bacterial resistance to antimicrobial agents in neonatal infections and the colonization of the neonatal gut with Gram negative bacilli. Her laboratory has identified some of the currently widely disseminated antibiotic resistance determinants in bacteria causing neonatal infections.Studies from her laboratory on extended spectrum β-lactamases and carbapenemases have shed light on the prevalence, genetic diversity of these enzymes and their modes of transmission in the context of neonatal infections.

Research Interests

The current research interest in our laboratory involves drug resistance in Gram negative bacilli that cause neonatal infections and studies on colonization of the neonatal gut with Gram negative bacilli.
We primarily study the highly antibiotic-resistant Gram-negative bacteria Acinetobacter baumannii, Klebsiella pneumoniae, and Escherichia coli. The main focus of the studies is on carbapenem and colistin resistance. Along with transmissible modes of resistance, role of multi-drug efflux pumps is also evaluated. Additionally, we are exploring the mechanisms related to pathogenesis in Acinetobacter baumannii and Klebsiella pneumoniae. The laboratory also provides molecular support to hospitals in the North Eastern parts of India and has been a part of the BARNARDS study examining the burden of neonatal sepsis in Pakistan, India, Bangladesh, Rwanda, South Africa, Nigeria (Abuja and Kano) and Ethiopia.
