Preliminary Observations on the Effect of Specific Immunity on Nasal Bacterial Flora |
|
| Authors: | J R Duncan and R G Thomson |
| Abstract: | This investigation has shown that Pasteurella hemolytica could actively colonize the nasal cavity of calves in the presence of indirect hemagglutinating IHA antibody against that particular strain. It was not determined if the level of nasal IHA antibody to Past. hemolytica had an effect on colonization of the nasal passage by Past. hemolytica. Specific immunity to Past. hemolytica would appear to be important in respiratory disease induced by this organism. |
