Role of wildlife and domestic pigs as reservoirs for hepatitis E virus (HEV): study of the infection in suids and cervids and of the susceptibility of pigs to HEV originating from wild boa
out of 29 livers from red deer, it belonged to genotype 3f. No HEV RNA was detected in red and roe deer sera. Using a multivariate logistic regression, a significant effect of age was observed: young ...
Prediction of respiratory disease and diarrhea in veal calves based on immunoglobulin levels and the serostatus for respiratory pathogens measured at arrival.
was judged to be too high to further postpone a group treatment. A Cox regression model was used to determine the effect of the studied protein fractions and antibodies on the time to BRD and NCD ...

taken, and a standardized clinical form was filled in for each animal. A clinical score was calculated for every week until the end of clinical signs. A classification and regression tree (CART) analysis ...
Serological and virological BVDV prevalence and risk factor analysis for herds to be BVDV seropositive in Belgian cattle herds.
their herd. Risk factors for a herd to be BVDV seropositive were identified by means of a multivariable logistic regression model. Large herds were significantly more likely to be BVDV seropositive (OR ...
Risk factors associated with brucellosis seropositivity among cattle in the central savannah-forest area of Ivory Coast.

Characteristics of serology-based vaccine potency models for foot-and-mouth disease virus.
implemented yet. The aim of the present study was to further characterize the properties of serological vaccine potency models. METHODS: Logistic regression models were built for 5 serological assays from ...
Impact of atmospheric deposition of As, Cd and Pb on their concentration in carrot and celeriac.
consumable part of the storage organs as a function of their atmospheric deposition. As such the experiments allowed deriving regression equations, useful for modeling the atmospheric impact of trace elements ...
Type and frequency of contacts between Belgian pig herds.
onto-farm movements was 0.2/month (Q1: 0; Q3: 0.5). About 1.2% of herds had > or = 3 onto-farm movements/month. We used a zero-inflated negative-binomial regression model to describe differences in the ...
Impact of human interventions on the spread of bluetongue virus serotype 8 during the 2006 epidemic in north-western Europe.
outside the AFI and the number of movements or the number of animals moved from the AFI to that municipality was assessed using a linear negative binomial regression model. The results of this study ...
Establishing the spread of bluetongue virus at the end of the 2006 epidemic in Belgium.
clinical suspicion. True within-herd seroprevalence was estimated based on a logistic-normal regression model with prior specification on the diagnostic test’s sensitivity and specificity. The model was ...
