Bacteriology begat Immunology in the early 20th Century, allowing this new scientific creation to become one of the most complicated of the biological sciences. A number of competing textbooks are now available, at various levels of complexity, for the graduate, postgraduate and professional scientist in the various biological disciplines. This volume is at the high end of the market and covers virtually everything you would ever need to know about modern immunology. The writing is clear and the diagrams are explicit. If there is a criticism to be made - there are too many diagrams! Microbiologists interested in animal or human infections need to know the latest view on immune mechanisms. This is the book for them as it covers the major systems of immunity from the perspective that immunity is largely a defence against infections. This book is for the postgraduate and is a must for microbiologists studying human/animal infection.
