Prevalence and associated risk factors for Mycobacterium avium subsp. paratuberculosis in dairy cattle in Mexico
The purpose of this study is to determine the seroprevalence and the associated risk factors to Mycobacterium avium subspecies paratuberculosis. A total of 4,487 serum samples were collected from cattle in 173 farms from different parts of Mexico. Information about potential risk factors and spatial location of the farms was obtained through a questionnaire to farm´ owners and by global positioning system (GPS)...

A Bayesian approach for inductive reasoning to clinical veterinary medicine: The math of experience
A Bayesian approach (BA) is well-used in veterinary medicine as it has been used for inductive reasoning regarding interventions, treatments and diagnoses. The objectives of the current article were (1) to examine the state of BA used for inductive reasoning in veterinary medical problems and (2) to illustrate how veterinarians update states of knowledge (prior clinical experience) to a new state of knowledge (posterior...

Bayesian estimation to test accuracy for influenza A infection via respiratory clinical signs in the absence of a gold standard
Influenza A virus (IAV) infection in pigs is a concern to producers, veterinarians and the general public. This study presents models to estimate the sensitivities (Se) and specificities (Sp) of respiratory clinical signs (RCS), and real-time reverse transcription polymerase chain reaction (RRT-PCR) resulted from oral fluid (OF) and nasal swab (NS) samples in the absence of a gold standard. In addition, the models...
