| combined enzyme and antimicrobial susceptibility profiles of caprine pasteurella haemolytica serovar 2 respiratory tract isolates. | the present investigation describes a novel method of demonstrating strain diversity among pasteurella haemolytica biovar a, serovar 2 (pha2) nasal turbinate isolates from a flock of 32 experimental goats during a naturally occurring outbreak of pasteurellosis. after a 21 day conditioning period in a feedyard, 51 pha2 isolates from 27 culture-positive goats were identified including 1 on day 22, 14 on day 25, 21 on day 39, and 15 on day 66. each pha2 isolate was evaluated for its enzyme activity ... | 1993 | 8306653 |
| effects of tilmicosin treatment on pasteurella haemolytica organisms in nasal secretion specimens of calves with respiratory tract disease. | to determine the effect of tilmicosin treatment on number of pasteurella haemolytica (ph) organisms in nasal secretion specimens of calves with respiratory tract disease. | 2000 | 10803647 |
| 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 |
