I am thankful to all my students for appreciation of the Second edition of “Complete Review of Microbiology and Immunology”. As per their suggestions, I have incorporated recent AIIMS Pattern MCQs with thoroughly revised Parasitology and Immunology Questions in this edition. This third edition is thoroughly revised and updated completely. Latest questions of recent NEET pattern and CET pattern with explanatory answers and questions from AIIMS, All India, PGI Chandigarh and various other state exams also incorporated in this edition. • New coloured recently asked images based questions are also included at the end of book. • Your suggestions, appreciation and criticism are most welcome. • Wishing you all the best for exams. • You can download my Microbiology App on Google Play Store and Apple Store for daily MCQs and Updates.
