Course Code: BBT302
Programme: B.Tech Biotechnology
Semester: 3rd Semester (Second Year)
Credits: 4 (3L + 1T)
Contact Hours: 4 hours/week
Course Objective:
To impart foundational and applied knowledge of microbiology and immunology, emphasizing microbial diversity, classification, physiology, pathogenicity, and host immune responses. The course integrates basic microbial techniques and immunological principles relevant to diagnostics and therapeutics.
