Association of Ovar‐DRB1 alleles with innate immune responses in sheep

open access: yesVeterinary Medicine and Science, Volume 8, Issue 2, Page 752-757, March 2022., 2022
Results of this study provided additional support for the association between Ovar‐DRB1 alleles and regulation of immune responses in sheep population. Description of MHC polymorphism and its role in the controlling of immune responses will increase our understanding of host‐pathogen interactions, and ultimately facilitate the selection of disease ...

A novel enterovirus in lambs with poliomyelitis and brain stem encephalitis

open access: yesTransboundary and Emerging Diseases, Volume 69, Issue 2, Page 227-234, March 2022., 2022
Abstract An Austrian organic dairy sheep farm experienced cases of recumbency and sudden deaths in 3‐ to 4‐week‐old lambs. Two animals were subjected to thorough clinical and pathological investigations. Pathohistological analysis identified severe nonsuppurative myelitis and mild nonsuppurative encephalitis.

Visna in a UK flock and the biosecurity risk arising from the onward sale of likely infected pedigree stock

open access: yesVeterinary Record Case Reports, Volume 9, Issue 3, September 2021., 2021
Abstract Small ruminant lentivirus infections in sheep most commonly present with respiratory signs (maedi) and indurative mastitis, while primary neurological signs (visna) have rarely been reported in Great Britain (GB). Most reports of visna describe signs referable to myelitis, although central signs associated with encephalitis may feature.
