Bordetelosis (Bordetella bronchiseptica)
Bordetella bronchiseptica is a bacterium that can cause fever or pneumonia in pigs. If there are not complications, and without the presence of toxigenic Pasteurella multocida type D, the disease has little clinical or economic consequences.
Description
Bordetella bronchiseptica is a bacterium found in almost all swine populations. Some strains cause a mild and nonprogressive rhinitis and it gets cured spontaneously. The disease has no clinical or economic consequences. However if toxigenic Pasteurella multocida type D is present in the farm, the combination of the two organisms can lead to a progressive atrophic rhinitis with serious economic consequences. Bordetella bronchiseptica may also be a secondary opportunistic in pneumonia cases.
Symptoms
Lactating and nursery piglets
- Cough.
- Sneezes.
- Nasal discharge.
Sows and fattening stage
- It is not present.
Causes / Contributing Factors
- A higher bacterial load may be present in an inadequate environment.
- Recirculation of air in creeps allow growth of the organism.
- Continued use of the building.
Diagnosis
- It is based on cultures and lab tests.
Control/Prevention
- It is not necessary unless the levels are high or it is concomitant with toxigenic Pasteurella multocida type D.
- Medication given via feed with trimethoprim, sulfonamides or chlortetracycline.
- Inject pigs at weaning with long lasting antibiotics.
- Replacement animals must come from farms that are negative for atrophic rhinitis.
