| the potential role of wild and feral animals as reservoirs of foot-and-mouth disease. | we investigated the potential role of feral pigs and wild deer as fmd reservoirs with a susceptible-latent-infected-recovered geographic-automata model, using spatially referenced data from southern texas, usa. an uncontrolled fmd outbreak initiated in feral pigs and in wild deer might infect up to 698 (90% prediction interval 181, 1387) and 1557 (823, 2118) cattle and affect an area of 166 km(2) (53, 306) and 455 km(2) (301, 588), respectively. the predicted spread of fmd virus infection was in ... | 2007 | 17316848 |
| diagnostic specificity of a real-time rt-pcr in cattle for foot-and-mouth disease and swine for foot-and-mouth disease and classical swine fever based on non-invasive specimen collection. | foot-and-mouth disease virus (fmdv) and classical swine fever virus (csfv) are highly contagious and can cause great economic losses when introduced into disease-free regions. accurate estimates of diagnostic specificity (sp) are important when considering the implementation of surveillance for these agents. the purpose of this study was to estimate diagnostic sp of a real-time reverse-transcriptase pcr assay developed for detection of fmdv in cattle and domestic swine and csfv in domestic swine ... | 2008 | 18499360 |
| modelling spread of foot-and-mouth disease in wild white-tailed deer and feral pig populations using a geographic-automata model and animal distributions. | we investigated how the size and distribution of wild deer and feral pigs - species that might act as potential foot-and-mouth disease (fmd) virus maintenance hosts - might affect the persistence and spread of fmd. we used a susceptible-latent-infected-recovered geographic-automata model and spatially referenced data from southern texas, usa. within this study area, 100 locations were randomly selected and fmd virus spread was simulated (50 simulations each) at each location. as expected, the pr ... | 2009 | 19515439 |
| acute bovine viral diarrhea associated with extensive mucosal lesions, high morbidity, and mortality in a commercial feedlot. | in 2008, a northwest texas feedlot underwent an outbreak of bovine viral diarrhea virus (bvdv) causing high morbidity and mortality involving 2 lots of calves (lots a and b). severe mucosal surface lesions were observed grossly in the oral cavity, larynx, and esophagus. mucosal lesions varied from small (1-3 mm) infrequent mucosal ulcerations to large (5 mm to 1 cm) and coalescing ulcerations. necrotic debris was present in ulcerations of some mortalities with some having plaque-like debris, but ... | 2012 | 22379057 |
