Bordetellosis (Bordetella bronchiseptica)
Related Products:
Bordetella bronchiseptica is a bacterium found in most if not all pig populations. Some strains cause a mild and non progressive rhinitis that heals spontaneously. The disease is clinically and economically of no consequence. However if toxigenic pasteurella are present in the herd then a combination of the two organisms can produce severe progressive rhinitis (PAR).
Bordetella bronchiseptica can also be a secondary opportunist invader in pneumonia.
