Background / Project

Dr. K. Natarajaseenivasan is a Professor and Principal Investigator in the Medical Microbiology Laboratory at the Department of Microbiology Bharathidasan University. He has received his post graduation in Microbiology from Madurai Kamaraj University, and was trained in Leptospirosis at Tamil Nadu Dr. MGR Medical University, where he has accomplished with Ph.D in Basic Medical Sciences. Previously he was a Research Officer at WHO Collaborative Centre for Diagnosis, Research, Reference and Training in Leptospirosis, Indian Council of Medical Research (ICMR), Port Blair, Andaman and Nicobar Islands.

He is interested to establish a continuous surveillance system and disease monitoring for medically important diseases like Leptospirosis, Salmonellosis, Ovarian and Cervical Carcinoma.  His current research provides new insights into microbial pathogenesis, novel protein and genetic markers for the early diagnosis of Leptospirosis.

His research trainings are focused in the following aspects.

1. Peptide based immuno pathogenesis for Leptospira interrogans serovar Autumnalis strain N2

2. Construction of Genomic DNA expression Library for Leptospira interrogans serovar Australis & Grippotyphosa

3. Molecular epidemiology for the transmission dynamics of L. interrogans  serovar Bratislavain Kentucky
