Chronic wasting disease associated with prion protein gene (PRNP) variation in Norwegian wild reindeer (Rangifer tarandus)
Guere Calderon, Mariella Evelyn; Våge, Jørn; Tharaldsen, Helene; Benestad, Sylvie Lafond; Vikøren, Turid; Madslien, Knut Ivar Engesæter; Hopp, Petter; Rolandsen, Christer Moe; Røed, Knut; Tranulis, Michael A. (Peer reviewed; Journal article, 2020)The emergence of CWD in Europe in 2016 and the first natural infection in wild reindeer warranted disease management. This led to the testing of 2424 hunted or culled reindeer during 2016–2018, from the infected subpopulation ... -
Designing a risk-based surveillance program for Mycobacterium avium ssp. paratuberculosis in Norwegian dairy herds using multivariate statistical process control analysis
Whist, Anne C; Liland, Kristian Hovde; Jonsson, Malin E; Sæbø, Solve; Sviland, Ståle; Østerås, Olav; Norström, Madelaine; Hopp, Petter (Journal article; Peer reviewed, 2014)Surveillance programs for animal diseases are critical to early disease detection and risk estimation and to documenting a population’s disease status at a given time. The aim of this study was to describe a risk-based ... -
Epidemiological investigations of footrot in the Norwegian sheep population
Grøneng, Gry Marysol (PhD Thesis;2015:22, Doctoral thesis, 2018-04-24)Footrot is a contagious disease where Dichelobacter nodosus, a Gram negative bacterium, is the necessary transmitting agent. The disease mainly affects small ruminants. The clinical signs range from mild inflammation in ... -
Estimation of the probability of freedom from Bovine virus diarrhoea virus in Norway using scenario tree modelling
Norström, Madelaine; Jonsson, Malin E; Åkerstedt, Johan; Whist, Anne C; Kristoffersen, Anja Bråthen; Sviland, Ståle; Hopp, Petter; Wahlström, Helene (Journal article; Peer reviewed, 2014)Disease caused by Bovine virus diarrhoea virus (BVDV) is notifiable in Norway. An eradication programme started in 1992. The number of herds with restrictions decreased from 2950 in 1994 to zero at the end of 2006. From ... -
The demographic pattern of infection with chronic wasting disease in reindeer at an early epidemic stage
Mysterud, Atle; Madslien, Knut Ivar Engesæter; Viljugrein, Hildegunn; Vikøren, Turid; Andersen, Roy; Guere Calderon, Mariella Evelyn; Benestad, Sylvie Lafond; Hopp, Petter; Strand, Olav; Ytrehus, Bjørnar; Røed, Knut; Rolandsen, Christer Moe; Våge, Jørn (Journal article; Peer reviewed, 2019)Infection patterns linked to age and sex are crucial to predict the population dynamic effects of diseases in long-lived species. How such demographic patterns of infection arise is often multifactorial, although the cause ...
