Parasitology provides all the basic principles of this increasingly studied subject, emphasised by specific, but important examples rather than covering organisms of just one particular group. It is ideally suited to the new modular/semester system now used by most universities and is laid out in the form of ‘notes' (rather than detailed descriptions), accompanied by simple flow charts and diagrams. Each chapter begins with a list of keywords and concepts. Where appropriate data from research papers is used to illustrate and emphasise the points.
