Evaluation of the fluorescence polarization assay for the detection of Brucella abortus antibodies in bison in a natural setting.

Bison and elk in the greater Yellowstone area are the last-known reservoir of Brucella abortus in the United States. Diagnosis of brucellosis is challenging as there is no perfect reference test. The objectives of this study were to estimate the accuracy of the fluorescence polarization assay (FPA) for the screening of B.

The North American Animal Disease Spread Model: a simulation model to assist decision making in evaluating animal disease incursions.

The North American Animal Disease Spread Model is a stochastic, spatial, state-transition simulation model for the spread of highly contagious diseases of animals. It was developed with broad international support to assist policy development and decision making involving disease incursions. User-established parameters define model behavior in terms of disease progression; disease spread by animal-to-animal contact, contact with contaminated personnel or equipment, and airborne dissemination; and the implementation of control measures such as destruction and vaccination.
