Major scientific breakthroughs in modem biology and in particular the branch which at present goes by the name of molecular biology, have centred around fungi, bacteria and viruses. What has been learnt about the how and why of life, in the last hundred years with the-help of the above three is by any yardstick a biological revolution. Man moved mountains but remained ignorant as to what ailed him or his cattle and crops. Hundreds of thousands of people frequently died in one stroke of epidemic like that of smallpox. The loss of cattle and crops was equally devastating. As late as 1840’s a potato famine in Ireland caused death of over one million people and an equally large number fltd to other places. But sweet are the uses of adversity as man has always been impressed by calamity. The arm-chair scientists could no more defer decision. Thehgernx^heory’ of disease propounded by Louis Pasteur, and Robert Koch was a great event in human history. Bacteria were proved to be the cause of several human and animal diseases. Anton de Bary, proved that Phytophthora, a fungus, was responsible for the Irish potato famine. The journey since then has been thrilling. The mysterious tobacco mosaic virus came as a parting gift of the 19th century. Many discoveries, having the effect of demolishing bombshells provided many intellectual shocks. TMV, though no longer as mysterious as it was in 1920’s quite often makes scientists feel like a child playing on the sea shore. The tempo of research is such that even really significant discoveries are accepted as common place.
It is always a pleasure to read and write about such important organisms. My brief for writing this book is one self-satisfaction. I have enjoyed myself writing this book. Hope students will also feel the same while reading it. I remember with gratitude my ‘microbial mentors’ Professors R.N. Tandon, T.s. Sạdasivan, K.s. Bhargava, K.s. Bilgrami, H.D. Kumar and Dr p.c. Misra. Thanks are due to my two research colleagues Dr H.N. Gour and Dr Miss Sunila Mathur for many stimulating and enjoyable discussions.
