Pathology and Pathogenesis of Bluetongue Infections

  • I. M. Parsonson
Part of the Current Topics in Microbiology and Immunology book series (CT MICROBIOLOGY, volume 162)

Abstract

Bluetongue disease is an infectious, noncontagious, arthropod-borne viral disease, mostly of sheep, but also of other ruminants (Erasmus 1975). The original detailed descriptions of bluetongue disease in sheep were those of Spreull (1905).
