Introduction & History of Microbiology | MBBS Lecture 1

Learn the foundations of clinical microbiology with Dr. Khyati, MBBS and second-year MD Microbiology resident. In Lecture 1 of this microbiology series, we begin with what clinical microbiology studies, compare prokaryotic and eukaryotic cells, explore the scientists who shaped the field, and discuss Koch’s postulates and their exceptions. This lecture is designed for MBBS students and anyone starting microbiology.
