The Department of Microbiology had had a modest beginning in March 2002 rendering diagnostic microbiology services, sharing a common lab along with clinical biochemistry and clinical pathology.

Currently it has developed its diagnostic services as well as improved teaching facilities to cater to an increased strength of 150 MBBS students, apart from BDS, B.Sc. Nursing, Post Basic Nursing, MD Microbiology and M.Sc. Medical Microbiology students. It offers quality diagnostic services to the various clinical departments at an affordable cost.

The microbiology department has three main roles:

  • Teaching/ Academic activities
  • Diagnostic laboratory services
  • Research activities


The department has a very good infrastructure for both under-graduate and post-graduate teaching and research activities. The department has 4 computers with LAN connection.

Student's lab and Demonstration rooms
The Student's Practical lab is spacious and furnished with 90 student microscopes. The department has two well furnished demonstration/ tutorial rooms. Epidiascope, slide projector and over head projectors are available.

Seminar room cum Departmental Library
The departmental library has 174 medical books catering to the needs of both the undergraduates and the postgraduates. It is very spacious with a large oval table and a seating capacity for 30 people. It has a computer with internet connection and a digital microscope with a 5 megapixel camera.


The department has an excellent museum with a vast collection of different specimens, charts, models etc (totaling 254) contributing immensely to under-graduate and post-graduate teaching. The medical students are encouraged to visit the museum.
