Department of Microbiology



The Department of Microbiology of All India Institute of Hygiene & Public Health, Kolkata is involved in the study of fundamental Microbiological problems relating to infectious diseases and with hygiene and public health.

It is probably the First Institute/College having a separate independent Microbiology Section/department in India.  It was established in the year 1932 during British Era. Professor K.V. Krishnan was the First Head of the Department of Microbiology.

The department is involved in teaching and training of the subject Microbiology to mainly all courses governed by this Institute. Our department runs a 2-year Post graduate course inMaster of Veterinary Public Health (MVPH) under the University of Calcutta. The department is involved in research activities including the supervision of dissertation work of the P.G. students of the different departments. Routine culture and susceptibility testing from clinical samples and the non-clinical samples is carried out routinely. The department is a recognized centre for testing the bacteriological quality of drinking water.  The department is also a recognized centre for “Yellow Fever Vaccination” to the travellers visiting to Yellow Fever disease affected countries.

Teaching Activities

  • Regular Courses Conducted:

  • The department runs a PG course namely Master of Veterinary Public Health (MVPH) under the University of Calcutta.

  • Short Courses / Trainings Conducted:

  • The department had participated in different Training Programme conducted by other departments of the Institute.

Regular Activities

  • Involved in taking the theoretical classes of all the courses governed by the Institute. The department is also involved in taking practical classes of the different courses allotted to the department.
  • Department runs an authorized Yellow fever vaccination centre and this year Yellow fever vaccine has been administered to 1934 international travellers visiting Yellow fever disease effected countries in Africa and South America.
  • Department is having authorized water bacteriology testing laboratory for potable water testing. This year department tested 280 water samples by the Water Bacteriology Section of the Department.
  • Media Room prepares thousands of different categories of culture mediawhich is utilized during the period of processing clinical and non clinical samples received in the Laboratories. The Washing Room and Sterilization Room are intimately associated with these media preparation process.
  • The department is routinely involved in testing the culture and sensitivity of clinical samples and non clinical samples for the research and teaching purposes. More than 700 samples were tested in last 12 months.
