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. The idea of a vaccine is that it introduces the body to a nonpathogenic virus or bacteria so that the immune system can recognize it and fight against it in the future.
Introduction. Bordetella pertussis was first isolated in pure culture in 1906 by Bordet and Gengou. Today, B pertussis belongs to the genus Bordetella in the family Alcaligenaceae, which contains several species of closely related bacteria with similar morphology. pertussis and B parapertussis cause whooping cough (pertussis) in humans. Other members of the genus are B bronchiseptica, which causes respiratory disease in various animals and is only occasionally found in humans.
