Bluetongue in Migratory Sheep Population

Bluetongue is one of the 15 diseases of OIE list 'A' affecting susceptible domestic and wild ruminants caused by Orbi virus transmitted by Culicoides. The economic losses are mainly attributed to high morbidity, mortality, abortions, stillbirths, foetal abnormalities and loss of milk, meat and fleece. Moreover the presence of this disease in a country puts trade barrier on movement of ruminant animals, their germ plasm and other animal products resulting in animal related international trade losses. The disease prevalence has been reported world wide and widespread in India (Sapre, 1964; Mehrotra, 1991; Janakiraman et al., 1991). In Tamil Nadu, it was first reported in Dindigul region in the year 1982 followed by sporadic incidence in the Southern districts during 1987. This study describes a disease investigation carried out in migratory sheep population suspected for bluetongue in Pudukkottai district of Tamil Nadu during the month of November 2004.
