Abstract
Viral arthritis/tenosynovitis, a disease caused by avian reovirus (ARV), leads to great economic losses for the chicken industry worldwide. Since autumn 2011, the poultry industries in the United States and Canada have sustained significant economic losses in the progeny of broiler breeders vaccinated with classic strains of ARV. Vaccination failure has been caused by field challenge with variant ARVs. The variant field ARVs are refractory to the immunity stimulated by classic vaccines and have become the prevalent challenge in the field. Because all genotypes described in the literature have been reported to be circulating in Canada, genotyping of circulating ARVs is paramount for the selection of appropriate isolates, representative of the field challenge, for use in autogenous vaccines. In this review, the history of ARVs and the current situation in Canada are discussed. On the basis of recent field data, inadequate measures commonly used in the field are discussed, and successful vaccination strategies are recommended.
期刊介绍：
Avian Diseases is an international journal dedicated to publishing original basic or clinical research of the highest quality from various disciplines including microbiology, immunology, pathology and epidemiology. Papers on avian diseases relevant to etiology, pathogenesis, diagnosis, treatment, and control are accepted. Manuscripts dealing with avian species other than poultry will be considered only if the subject is relevant to poultry health.
