Description
Summary:The Bunyaviridae are the largest family of arthropod-borne viruses and include many significant pathogens of man and domestic animals. Members of this family have been isolated on all continents except the Antarctic, from mosquitoes, ticks, phlebotomine insects and a wide range of vertebrates. Nairobi sheep disease (NSD) and Rift Valley fever (RVF) were the first two recognized diseases caused by members of this family; both are responsible for high mortality epizootics in sheep and febrile infections in man. Many viruses of this family have produced febrile infections in man with encephalitis and hemorrhagic fevers. Members of the Simbu group have been responsible for epizootics in cattle, sheep and goats in which congenital abnormalities occur. Although this family of viruses has been studied intensively in recent years, comparatively little is known of canine infections. This report discusses; Virus Physical; Chemical and Antigenic properties; Epizootiology; Pathogenesis and Disease Signs; Pathology; Laboratory Diagnosis and Prophylaxis and Control.
