Atlas entirely dedicated to infectious bursal disease based on a practical and graphic approach of the topic. This handbook has been carried out by highly experienced authors closely involved with this disease in Africa, where its prevalence and incidence are significant. This updated work has been carefully developed including the most essential contents, so that it depicts a valuable tool to cope and control this virus as far as possible. Includes many helpful tips and visual graphic resources provided by the authors to enrich and turn this atlas into a reference in its field. Furthermore, diagnosis and vaccination have been thoroughly explained, highlighting vaccination programmes and types of vaccines. The atlas format helps to make the contents understandable and affordable for the readers.
