Porcine Reproductive and Respiratory Syndrome virus (PRRSv): A Cross-Sectional Study on ELISA Seronegative, Multivaccinated Sows
using IDEXX ELISA (ELISA 1) and CIVTEST E/S ELISA (ELISA 2). Neutralizing antibodies (NA bs) were quantified in a virus neutralization assay. Univariable logistic regression was used to identify herd risk ...
Porcine Reproductive and Respiratory Syndrome virus (PRRSv): A Cross-Sectional Study on ELISA Seronegative, Multivaccinated Sows.
regression was used to identify herd risk factors for the presence of ELISA non-responders. The global prevalence of non-responders varied from 3.5% (ELISA 1) to 4.1% (ELISA 2), the herd-level prevalence was ...
Outbreak investigations and molecular characterization of foot-and-mouth disease viruses circulating in south-west Niger.
using a non-structural protein (NSP) test provided evidence for previous FMDV infection in 70% (158/227) of the sera tested. Multivariate logistic regression analysis revealed that only the herd ...
Seroprevalence of brucellosis in patients with prolonged fever in Bangladesh.
and indirect enzyme-linked immunosorbent assay (iELISA). Risk factors were identified by multivariate Firth’s logistic regression analysis. Brucella genus (BCSP31) and species-specific (IS711) rtPCR ...
A trend analysis of antimicrobial resistance in commensal Escherichia coli from several livestock species in Belgium (2011-2014).
regression and Generalized Estimating Equation and after p value adjustment for multiple testing (Linear step-up method), statistically significant decreasing temporal trends were observed for several of the ...
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.
iELISA results showed that 10.3% (95% confidence interval (CI): 8.4, 12.4) of the cattle had antibodies against Brucella in our study area. The logistic regression analysis indicated that brucellosis ...
