Describes the expansions of microbiology; it's methods, from traditional microscopy and laboratory culture to the latest genomic analysis. --

Bacteria form a fundamental branch of life. They are the oldest forms of life as we know it, and they are still the most prolific living organisms. They inhabit every part of the Earth's surface, its ocean depths, and even terrains such as boiling hot springs. They are most familiar as agents of disease, but benign bacteria are critical to the recycling of elements and all ecology, as well as to human health. In this Very Short Introduction, Sebastian Amyes explores the nature of bacteria, their origin and evolution, bacteria in the environment, and bacteria and disease. In looking at our efforts to manage co-evolving bacteria, he also considers the challenges of resistance to antibiotics.

Viruses are big news. From pandemics such as HIV, swine flu, and SARS, we are constantly being bombarded with information about new lethal infections. In this Very Short Introduction, Dorothy Crawford demonstrates from their discovery and the unravelling of their intricate structures, how clever these entities really are.

As doctors and biologists have learned, to their dismay, infectious disease is a moving target: new diseases emerge every year, old diseases evolve into new forms, and ecological and socioeconomic upheavals change the transmission pathways by which disease spread. By taking an approach focused on the general evolutionary and ecological dynamics of disease, this Very Short Introduction provides a general conceptual framework for thinking about disease. Ecology and evolution provide the keys to answering the 'where', 'why', 'how', and 'what' questions about any particular infectious disease: where did it come from? How is it transmitted from one person to another, and why are some individuals more susceptible than others? What biochemical, ecological, and evolutionary strategies can be used to combat the disease? Is it more effective to block transmission at the population level, or to block infection at the individual level? Through a series of case studies, Benjamin Bolker and Marta L. Wayne introduce the major ideas of infectious disease in a clear and thoughtful way, emphasising the general principles of infection, the management of outbreaks, and the evolutionary and ecological approaches that are now central to much research about infectious disease.

This text is about the central role of evolution in shaping the nature and diversity of the living world. It describes the processes of natural selection, how adaptations arise, and how new species form, as well as summarizing the evidence for evolution

Molecular Biology is the story of the molecules of life, their relationships, and how these interactions are controlled. It is an expanding field in life sciences, and its applications are wide and growing. We can now harness the power of molecular biology to treat diseases, solve crimes, map human history, and produce genetically modified organisms and crops, and these applications have sparked a multitude of fascinating legal and ethical debates. In this Very Short Introduction, Aysha Divan and Janice Royds examine the history, present, and future of Molecular Biology. Starting with the building blocks established by Darwin, Wallace and Mendel, and the discovery of the structure of DNA in 1953, they consider the wide range of applications for Molecular Biology today, including the development of new drugs, and forensic science. They also look forward to two key areas of evolving research such as personalised medicine and synthetic biology.

Throughout history plague has been the cause of many major catastrophes. It was responsible for the Black Death of 1348 and the Great Plague of London in 1665, and for devastating epidemics much earlier and much later, in the Mediterranean in the sixth century, and in China and India between the 1890s and 1920s. Today, it has become a metaphor for other epidemic disasters which appear to threaten us, but plague itself has never been eradicated. In this Very Short Introduction, Paul Slack explores the historical impact of plague over the centuries, looking at the ways in which it has been interpreted, and the powerful images it has left behind in art and literature. Examining what plague meant for those who suffered from it, and how governments began to fight against it, he demonstrates the impact plague has had on modern notions of public health and how it has shaped our history.
