Title: The nasopharyngeal microbiota of beef cattle before and after transport to a feedlot Document date: 2017_3_22
ID: 1nni3vhm_20
Snippet: Nasopharyngeal swabs were first screened for the BRDassociated bacteria H. somni, M. haemolytica, and P. multocida, using culture-based methods and isolates were confirmed using PCR. Neither H. somni nor M. haemolytica were isolated during the study period (Additional file 3: Table S2 ). Interestingly, although P. multocida was isolated from the nasopharynx of eight heifers, none of these animals remained positive for P. multocida at all four sam.....
Document: Nasopharyngeal swabs were first screened for the BRDassociated bacteria H. somni, M. haemolytica, and P. multocida, using culture-based methods and isolates were confirmed using PCR. Neither H. somni nor M. haemolytica were isolated during the study period (Additional file 3: Table S2 ). Interestingly, although P. multocida was isolated from the nasopharynx of eight heifers, none of these animals remained positive for P. multocida at all four sampling times. Furthermore, by day 14, P. multocida was isolated from only one animal.
