Apurba Sastry Microbiology PDF Book

Microbiology is difficult to understand as there are numerous pathogen and histopathological findings one has to study. Looking at the microscope, we often confuse ourselves.

Apurba Sastry book helps students understand the key concepts. Although there are many books available to read, this book has its own place for MBBS students. You can opt for Ananthanarayan and Paniker if you wish so.

This book provides some amazing diagrams, neat and precise headings, and the finest structural organization. The procedures for various steps are beautifully narrated with images.

This book has its own fandom and is considered for use after MBBS as well. Many students opt for it while preparing for the NEET PG exam. Apart from the above-mentioned features, there are in-depth topics and tables which help students memorize important topics in microbiology easily.


The following updates were done in the 3rd Edition of the Apurba Sastry Microbiology PDF book:

  1. Parasitology has been incorporated and therefore it obviates the reading of a separate book.
  2. The Hospital Infection Control section has been thoroughly updated with the inclusion of new topics such as major hAI types,
    monitoring of antimicrobial stewardship, escalation vs de-escalation strategy, donning/doffing of PPE, and transmission-
    based precautions.
  3. ™The General Microbiology section has been meticulously restructured with the inclusion of general virology, general
    parasitology, and general mycology chapters. General bacteriology is reorganized into a single chapter with several
  4. ™Overview chapters have been incorporated in the general microbiology section, which will help in better understanding
    individual organisms when discussed under systemic microbiology.
  5. The sterilization and disinfection chapter has been completely revised based on the hospital’s use of sterilizers and disinfectants;
    and has been shifted to the hospital Infection Control section.
  6. A chapter on CoVID-19 has been added, covering the latest pandemic in detail.
  7. The annexures section has been expanded to include several new topics such as opportunistic infections, transplant infections,
    national health programs for communicable diseases, vector-borne diseases, transfusion-transmitted infections and
    AETCoM in Microbiology.
  8. The AETCoM module has been added as a new annexure, which covers topics pertaining to confidentiality in disclosing
    laboratory reports and demonstration of respect for patient samples.

You can access the bookmarks section to easily navigate through the book.

Suggestions to those studying Microbiology from Apurba Sastry book in the Second Year MBBS are as follows:

  1. Stay active in lectures and classes. Jot down essential points your professors teach you. Use them wisely days before the exam.
  2. Make your own concise notes in your own handwriting. This helps in creating a visual memory which helps recall important topics easily in the exam hall.
  3. Have a better grasp of finds on microscopy. Practicals are relatively difficult and many mug them up. In real scenarios, it becomes disastrous to understand any single of them.
  4. Make your own list of important topics which need to be revised thoroughly before the exam.
  5. You can also read Ananthanarayan and Paniker’s Textbook of Microbiology.
