Systematic Veterinary Virology

INTRODUCTION

• The term Reo refers to Respiratory Enteric Orphan viruses, i.e. infect the human respiratory and intestinal tracts, usually without disease symptoms. Bluetongue (BT) is a non-contagious, athropod-borne viral disease of sheep and other domestic and wild ruminants, such as goats, cattle and deer.
• Camelids are also affected by BT. The infection in animals is transmitted through the bite of Culicoides insects. Bluetongue virus (BTV) is endemic in some areas with cattle and wild ruminants serving as reservoirs for the virus.
