Accuracy of paratuberculosis diagnostic tests in small ruminants: Protocol for a systematic review and meta-analysis
(2019)Paratuberculosis is a worldwide infectious disease caused by Mycobacterium avium ssp. paratuberculosis (MAP). Various ruminant species can be affected by the disease, and the diagnosis of the disease is challenging in the ... -
Application of a semi-dependent latent model in the Bayesian estimation of the sensitivity and specificity of two faecal culture methods for diagnosis of paratuberculosis in sub-clinically infected Greek dairy sheep and goats
(2006)In this study, we compared the frequency of isolation of Mycobacterium avium subsp. paratuberculosis (MAP) from faecal samples grown on Herrold's egg-yolk medium (HEYM) or on Lowenstein-Jensen (LJ) medium and estimated the ... -
Application of Bayesian modeling for diagnostic assays of Mycobacterium avium subsp. paratuberculosis in sheep and goats flocks
(2022)Background: This study aimed to screen the sera of goats and sheep from flocks suspected of Mycobacterium avium subsp. paratuberculosis (MAP) infection by a newly standardized Mce-truncated ELISA (Mt-ELISA) kit for the ... -
Bayesian estimation of sensitivity and specificity of a commercial serum/milk ELISA against the Mycobacterium avium subsp. Paratuberculosis (MAP) antibody response for each lactation stage in Greek dairy sheep
(2016)A total of 854 paired milk and blood samples were collected from ewes of a Greek flock and used to estimate the sensitivity and specificity of a commercial ELISA for detection of Mycobacterium avium subsp. paratuberculosis ... -
Bayesian estimation of the true prevalence of paratuberculosis in Hungarian dairy cattle herds
(2020)Paratuberculosis is a chronic incurable disease caused by Mycobacterium avium subsp. paratuberculosis (MAP), which leads to extensive economic losses on dairy farms, and may also pose serious public health risk to the ... -
Bayesian estimation of variance partition coefficients adjusted for imperfect test sensitivity and specificity
(2009)The variance partition coefficient (VPC) measures the clustering of infection/disease among individuals with a specific covariate pattern. Covariate-pattern-specific VPCs provide insight to the groups of individuals that ... -
Bayesian mixture models for partially verified data: Age- and stage-specific discriminatory power of an antibody ELISA for paratuberculosis
(2013)Bayesian mixture models can be used to discriminate between the distributions of continuous test responses for different infection stages. These models are particularly useful in case of chronic infections with a long ... -
A Bayesian Weibull survival model for time to infection data measured with delay
(2010)Survival analysis methods can be used to identify factors associated with the time to induction of infection In the absence of a perfect test, detection of infection is generally delayed and depends on the duration of the ... -
Control of paratuberculosis: Who, why and how. A review of 48 countries
(2019)Paratuberculosis, a chronic disease affecting ruminant livestock, is caused by Mycobacterium avium subsp paratuberculosis (MAP). It has direct and indirect economic costs, impacts animal welfare and arouses public health ... -
Dam's infection progress and within-herd prevalence as predictors of Mycobacterium avium subsp. paratuberculosis ELISA response in Danish Holstein cattle
(2016)Understanding the primary routes of transmission of Mycobacterium avium subsp. paratuberculosis (MAP) is pivotal to manage the pathogen in cattle herds. MAP is transmitted both vertically and horizontally, and both the ... -
Flock-level factors associated with the risk of Mycobacterium avium subsp paratuberculosis (MAP) infection in Greek dairy goat flocks
(2014)In this cross-sectional study we identified flock-level risk factors for Mycobacterium avium subsp. paratuberculosis (MAP) infection, in Greek dairy goat flocks. We collected 1599 milk samples from does that were at the ... -
Pancreatic anti-GP2 and anti-Saccharomyces cerevisiae antibodies in ruminants with paratuberculosis: A better understanding of the immunopathogenesis of Crohn's disease
(2020)Introduction: Ruminants (cattle and sheep) with Mycobacterium avium (MAP)-induced paratuberculosis (ptb), the ruminant model of Crohn's disease (CD), exhibit pancreatic specific autoantibodies (PAB) against GP2 but not ... -
A stochastic simulation model for the efficacy of vaccination against Mycobacterium avium subsp. paratuberculosis in dairy sheep and goats
(2015)We assessed the benefits of vaccination against Mycobacterium avium subsp. paratuberculosis (MAP) on the average daily milk yield (DMY) of sheep and goat flocks. A stochastic simulation model was used to estimate the DMY ...
