Bordetellosis (Bordetella bronchiseptica)
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.
SymptomsPiglets & Growers
- Nasal discharge.
Causes / Contributing factors
- High levels of the bacteria may predominate in poor environments.
- Recirculation of air in nurseries allows a build up of organisms.
- Continual use of housing.
This is based on cultural and laboratory examinations.
- None needed unless levels are high
- In-feed medicate with trimethoprim sulpha or chlortetracycline
- Inject weaners with oxytetracycline lang acting at weaning
