Microbiology is a diverse discipline.e novice. The traditional books

seem to be too long and detailed to be read by the undergraduatel student who is trying to keep up with several classes simultaneously of other subjects. This book contains all of the information that is useful undergraduate Microbiology studying students who are studying microbiology keeping in mind their examination. 

It cover many aspects of bactrial diversity in depth. The book is divided into eight chapters. The chapters are comprehensive yet free of unnecessary detail and provide the reader with a framework for understanding.

I shall be thankful for any comment or suggestions from students, teachers and all the readers of the book for further improvements.
