Medical microbiology concerns the nature, distribution and activities of microbes and their impact on health and wellbeing. In spite of the introduction of many antimicrobial agents and immunisations, we continue to face major challenges in combatting infection, not least the gathering crisis in antimicrobial resistance. Now in a fully revised and updated 19th edition, Medical Microbiology provides comprehensive coverage of infection from the microbial perspective, combining a clear introduction to key principles with a focus explicitly geared to modern clinical practice. It provides ideal coverage for medical and biomedical students – with ‘Key Points’ boxes throughout to highlight the essentials – and sufficient detail to also inform specialists in training.
