Symptoms
-
Chronic sneezing is one of the first signs of rhinitis in pigs. Other signs may include runny eyes, discharge from the nose, bloody nose or a shortening or twisting of the upper jaw.
Diagnosis
-
Rhinitis can be diagnosed with nasal swabs of the nose and examination of the snout for significant loss of turbinate tissue (tissue in structures of the nose).
-
Treatment
-
Long-acting antibiotic medications like amoxicillin are an effective form of treatment in pigs if the disease is caught early enough.
Spread of Disease
-
Many pigs carry the bacteria that cause rhinitis but do not display symptoms. They can pass the disease on to other pigs via nose-to-nose contact or ingestion of droplets from the nose.
Prevention/Solution
-
Pigs with which an infected pig may come in contact should be vaccinated against rhinitis, and the infected pig should be quarantined for up to six weeks.
