Louis Pasteur (1822 – 1895)

Louis Pastuer was a French chemist and microbiologist born in Dole. He is remembered for his remarkable breakthroughs in the cause and prevention of diseases. His discoveries reduced mortality from puerperal fever, and he created the first vaccine for rabies and anthrax. His experiments supported the germ theory of disease. He is best known to the general public for inventing a method to stop milk and wine from causing sickness, a process that came to be called pasteurization. He is regarded as one of the three main founders of microbiology, together with Ferdinand Cohn and Robert Koch.

Professor & Head of the Department

Message of the Chair
Established in 1967 under the broad umbrella of Pathology & Bacteriology, this department evolved into an independent Department of Microbiology under the leadership of Dr.Ramajeyam. The department presently serves a nodal point for microbiology diagnosis, research and teaching for the southern districts of the State of Tamilnadu. This department has grown in tandem with the medical needs of our patients and the society around. A Voluntary Counseling & Testing Centre for HIV was established in 1999, which was later elevated to a Regional Reference Laboratory under NACO in 2000 and a Integrated Counseling & Testing Centre in 2002. Molecular Diagnostics Lab was established in 2010.

Academic Program


 GRADUATE ACADEMIC PROGRAMS
The department trains graduate medical students during the 3rd to 5th semesters. The curriculum, affiliated to the Tamilnadu Dr.M.G.R.Medical University integrates theoretical and practical training to the 150 students every year. The students are also encouraged to undertake Short term projects under ICMR during the course period. The course includes a planned yearly calendar of didactic lectures, seminars, symposia, integrated sessions and clinical interaction sessions. The department also encourages the students to undertake community studies in microbiology.

RESIDENCY TRAINING PROGRAM
The department has 15 residency posts with 5 fresh intakes a year. The residents are taken through a program as per the Tamilnadu Dr.M.G.R.Medical University regulations and integrate theoretical, clinical and practical training spread over three years. The students are also encouraged to undertake Short term research projects and make a detailed research thesis to be completed and presented before the end of the three years. The course includes a planned yearly calendar of three monthly residency posts with didactic lectures, seminars, symposia, integrated sessions, clinical interaction sessions, journal clubs and case discussions. The department also encourages the students to undertake community studies in microbiology.

Eligibility: M.B.B.S. Degree from any Indian university recognized by the Medical Council of India & and obtained permanent registration from any of the State Medical Councils.

Course duration: 3 years.

Selection procedure: Selection for two/three of the five seats of residents will through the Tamilnadu Post Graduate Entrance Examination and the remaining three/two seats through the All India Post Graduate Entrance Examination conducted by DGHS, New-Delhi.

Academic Curriculum: The objective of the program is to: (1) Establish good clinical microbiological services in a hospital and in the community in the fields of bacteriology, virology, parasitology, immunology and mycology.
