First identification of <i>Bordetella bronchiseptica</i> subclinical mastitis in a lactating dairy cow in New Zealand

Only one other case report could be found of this organism being identified in milk samples. Greater use of advanced identification systems will likely increase the number of organisms identified from mastitic milk samples. Appropriate identification is important to aid decision-making as, given the response to therapy and laboratory findings, there is a poor likelihood of bacteriological cure with beta-lactam therapy for this organism.
