This man, born poor, with little education, a draper in his hometown of Delft had surprising visitors! They included great men of science as well as the Royalty like the Tsar Peter the Great, Frederick the Great of Prussia and King James II of England. This was due to his hobby of grinding fine lenses through which he looked at various objects and brought forth the wonder world of small things that none had seen before. He kept clear descriptions and accurate drawings of what he saw and communicated them to the Royal Society in London. A strict check convinced the Society of their authenticity. The unlettered Antonie was elected a Fellow of the Royal Society! The papers sent by him over decades can still be seen in the Philosophical Transactions of the Royal Society.
The discoveries he made are legion. He described the first protozoan pathogen Giardia. He also discovered many types of bacteria, human and animal spermatozoa, and eggs of various animals realizing their importance in reproduction. He could not recognize the significance of the different types of bacteria, and to him, they were just ‘little animalcules’. His fault was in being much before the time, for it took two centuries more for people to accept the microbial origin of infectious diseases. But that should not deter us from acknowledging the great contributions made by Leeuwenhoek to Biology and many other branches of Science. He was truly the Founder of Microbiology.

7Preface to the Seventh Edition
The current edition of this book is written in a new user-friendly format in contrast to the classic narrative style of Dr. Paniker's Textbook of Medical Parasitology that has served medical students and teachers for more than 25 years since 1988.
Considering the advancement in the field of Parasitology, I have updated the text thoroughly, incorporating the recent epidemiological data and new diagnostic methods especially the molecular techniques and current treatment modalities. Almost all chapters have been revised and few new chapters like Pnemocystis jirovecil, Microsporidia, and Balantidium coli are added.
The main emphasis of the current edition is to make the text more comprehensive, colorful, and student-friendly. Diagrams of life cycle have been redrawn in a manner to facilitate the students reproduce them during examinations. Several new tables, flowcharts, and easy-to-remember boxes are given to equip the students for better answering of theory and oral questions during examinations. More microscopic view pictures, photographs of specimens, and diagnostic images have been added in a manner to favor better visible impressions of parasitic diseases. I have included “Key points” of important parasites in box formats to highlight “must know facts” that are pertinent to the topic.
Important MCQs and review questions carefully selected from various university examination papers have been added to test and reinforce understanding of the topic by the student.
The aim of the book remains to be compact, yet informative, and useful for both undergraduate and postgraduate students.
My endeavor will be successful, if the book is found to be useful for faculty and students.
Expressions and emotions fail to find words to express thanks to my parents. I thank them for a being a constant source of inspiration and motivation.
I am grateful to all the colleagues in my department for their valuable suggestions during preparing the texts.
I am especially indebted to the Director and Staff of School of Tropical Medicine, Kolkata for providing mounted specimens.
I gratefully acknowledge the help of Mr Jitendar P. Vij (Group Chairman), Mr Ankit Vij (Managing Director), Mr Tarun Duneja (Director Publishing) and Mr Sabyasachi Hazra for their professional help and guidance during the project.
The insight and skills of Dr Sakshi Arora (Chief Development Editor) along with her team helped in polishing this book to best meet the needs of students and faculty alike.
Lastly I acknowledge the support extended by my family members during revising the book.
All suggestions are welcome and may be emailed to: s_ghosh2006@rediffmail.com

8Preface to the First Edition
Parasitic infections continue to account for a large part of human illness. Antimicrobial drugs and vaccines that have made possible the effective control of most bacterial and viral diseases have not been as successful against parasitic infections. The numbers of persons afflicted by parasites run into many millions. Malaria still affects over 500 millions, pinworm and whipworm 500 millions each, hookworm 800 millions and roundworm a billion persons. Filariasis, leishmaniasis and schistosomiasis remain serious public health problems. Infections due to opportunist parasites are becoming increasingly evident in the affluent countries.
In recent years there has been a resurgence in the study of parasitic infections. Much new knowledge has been gained making possible precise diagnosis and more effective control of parasites and the diseases they cause.
This textbook attempts to present the essential information on parasites and parasitic diseases, with emphasis on pathogenesis, epidemiology, diagnosis and control. Every effort has been made to incorporate recent advances in the subject.
It is hoped that medical students, teachers and physicians will find this book useful. Their comments and suggestions for improvement of the book will be most welcome.
