Summary and Implications
The use of a Moraxella bovis selective agar, preferentially over sheeps blood agar, may be a valuable method to increase laboratory culture recovery of M. bovis and M. ovis from IBK cases where those organisms are suspected. There was no difference in recovery rates from SBA plates incubated at 5 or 10% CO2. It remains to be determined if increased recovery is clinically significant and associated with disease occurrence.
