This completely new manual describes diseases of dogs and cats caused by bacteria, fungi and viruses, as well as protozoans and other parasites. Aimed primarily at UK vets in general practice, the book concentrates on common conditions such as cat 'flu, infectious diarrhoea and pyoderma. It also includes detailed information on a number of important diseases that may be seen in animals imported into the UK. Several infectious diseases that might be seen in quarantined animals are covered but in less depth. Important non-infectious differential diagnoses are noted in the text where appropriateA problem-oriented rather than a 'pattern recognition' approach has been adopted. Infections are grouped together by affected body systems rather than by taxonomic classification. Thus, all gastrointestinal viruses, bacteria and parasites are considered in one chapter. When an infectious agent has more than one presentation (e.g. canine distemper virus) then one chapter contains the main details of clinical signs, diagnosis, treatment and control. Other chapters contain relevant details of clinical signs for the system but the reader is cross-referred to the main chapter for other information. Although the Manual does not provide details of microbial structure, replication, molecular biology and post-mortem findings that are not directly important to the practitioner, modern diagnostic techniques using molecular biology are described.The authors have been drawn from a wide variety of institutions in the UK and were selected for their knowledge of internal medicine and infectious diseases. The text is extensively illustrated throughout with numerous tables, illustrations and flow charts plus quality colour photographs.
