When the disease is caused by a single agent it is known as Bordetellosis.he disadvantage of the nasal vaccine is that some pets develop a mild respiratory disorder, especially after the first vaccination.

The poliovirus affected, in many different patterns, the nerve cells in the lower brain (bulbar) and spinal cord that control the muscles of the body. Poliovirus does not damage the lung tissue or the nerves to the airway muscle. When the bulbar nerves were destroyed (bulbar polio), the muscles of the throat were weakened. This resulted in choking during eating and a diminished ability to cough.
