- A hypothesis is a proposition, set forth as an explanation for the occurrence of a phenomenon, that can be tested. - The basis for scientific investigation is the collection of information to formulate and test hypotheses. - Experimental methods measure the effect of manipulations caused by the investigator; observational methods collect information about naturally occurring events. - There are three sub-types of experimental techniques that differ in the way subjects are chosen for inclusion in the study, in the amount of control that the investigator has over variables, and in the method used to assess changes in other variables. - Descriptive observational studies dominate the early phase of most investigations and involve the description of disease-related events in the population. Associations among factors may be observed but the strength of the associations is not measured. - Analytical observation al techniques are of three basic types: prevalence surveys, case:control studies, and incidence or cohort studies. All attempt to explain the nature of relationships among various factors and to measure the strength of associations. - Prevalence surveys and case:control studies deal with disease existing at the time of the study; incidence studies are concerned with the development of disease over time. - Observational studies may be retrospective, using existing data, or prospective with collection of new information.

INFECTIOUS DISEASES OF WILD MAMMALS AND BIRDS IN EUROPE Infectious Diseases of Wild Mammals and Birds in Europe is a key resource on the diagnosis and treatment of infectious diseases in European wildlife that covers the distinctive nature of diseases as they occur in Europe, including strains, insect vectors, reservoir species, and climate, as well as geographical distribution of the diseases and European regulations for reporting, diagnosis and control. Divided into sections on viral infections, bacterial infections, fungal and yeast infections, and prion infections, this definitive reference provides valuable information on disease classification and properties, causative agents, epidemiology, pathogenesis, and implications for human, domestic and wild animal health. KEY FEATURES: Brings together extensive research from many different disciplines into one integrated and highly useful definitive reference. Zoonotic risks to human health, as well as risks to pets and livestock are highlighted. Each disease is covered separately with practical information on the animal species in which the disease has been recorded, clinical signs of the disease, diagnostic methods, and recommended treatments and vaccination. Wildlife vaccination and disease surveillance techniques are described. Examines factors important in the spread of disease such as changing climate, the movement of animals through trade, and relaxations in the control of wild animal populations. Written by a team of pathologists, epidemiologists and clinicians from across Europe, this is the definitive resource for infectious diseases of wild mammals and birds in Europe. It will be an invaluable reference for veterinarians, conservation biologists, epidemiologists, and wildlife researchers, managers, rehabilitators and students.
