| pathogens of bovine respiratory disease in north american feedlots conferring multidrug resistance via integrative conjugative elements. | in this study, we determined the prevalence of bovine respiratory disease (brd)-associated viral and bacterial pathogens in cattle and characterized the genetic profiles, antimicrobial susceptibilities, and nature of antimicrobial resistance determinants in collected bacteria. nasopharyngeal swab and lung tissue samples from 68 brd mortalities in alberta, canada (n = 42), texas (n = 6), and nebraska (n = 20) were screened using pcr for bovine viral diarrhea virus (bvdv), bovine respiratory syncy ... | 2014 | 24478472 |
| an evaluation of the relative efficacy of tulathromycin for the treatment of undifferentiated fever in feedlot calves in nebraska. | a field trial was performed under commercial feedlot conditions in central nebraska to assess the relative efficacy of tulathromycin (tula) to florfenicol (flor) for the treatment of undifferentiated fever (uf) in feedlot calves that did not receive a metaphylactic antimicrobial or vaccines/bacterins containing mannheimia haemolytica or histophilus somni at feedlot arrival by comparing animal health, feedlot performance, and carcass characteristic variables. two hundred recently weaned, auction ... | 2007 | 17616056 |
