Bordetella is a bacterial illness caused by Bordetella bronchoseptica that affects dogs and cats. 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.

Description and significance. Bordetella pertussis is a small, Gram-negative, coccoid bacterium about the size of 0.8 Âµm by 0.4 Âµm. It is an encapsulated immotile aerobe that does not make spores. Bordetella pertussis produces a number of virulence factors, including pertussis toxin, adenylate cyclase toxin, filamentous hemagglutinin, and hemolysin. It cannot survive in the environment; it must reside in a host either in small groups or singly.
