Grapevine Vein Clearing Virus: Epidemiological Patterns And Construction Of A Clone, Cory Von Keith Aug 2018

Grapevine Vein Clearing Virus: Epidemiological Patterns And Construction Of A Clone, Cory Von Keith

MSU Graduate Theses

Grapevine vein clearing virus (GVCV) is a recently discovered virus belonging to the Badnavirus genus. Characteristic to its name, the virus is associated with a disease where symptoms manifest as pronounced vein-clearing, resulting in severe berry deformation and vine decline in susceptible grape varieties. Sustainable production of wine is dependent on healthy plants. The associated disease is mainly found in Midwest vineyards. Attempts were made in this thesis to provide evidence of causality of the virus to the associated disease and to infer the historical path and migration pattern of GVCV. Conclusions and discussions will provide grape producers with the …

Osteoarthritis In The Pelvic Limb Of Captive Cranes, Barry K. Hartup, Savannah J. Lauer, Alyson R. Manthei

Proceedings of the North American Crane Workshop

We conducted an epidemiological study of osteoarthritis (OA) among the 15 captive crane species managed at the International Crane Foundation from 1973 to 2016. A retrospective review of 714 medical records found 37 cases of OA in 13 species of cranes and a corresponding period prevalence of OA of 5%. An analysis of the living captive crane flock as of 1 October 2016 (n = 115) found 12 active cases of OA (a point prevalence of 10%), and there was a statistical association between geriatric age classification (i.e., advanced age) and the presence of OA (P < 0.01). The mean age of cranes with OA was 14 years greater than cranes without the disease (P < 0.001). The prevalence estimates of OA from this review were somewhat lower than that from study of museum specimens, but this study similarly identified the tarsal joint as the predominant location of OA lesions in cranes.
