Bordetella organisms: The most important species in this genus is B. pertussis, the organism which causes
whooping cough. This highly contagious bacterium makes its way into the respiratory tract via inhalation and
subsequently binds to and destroys the ciliated epithelial cells of the trachea and bronchi. It does this through the use of
several toxins: B. parapertussis is a respiratory pathogen that can cause mild pharyngitis. This bacterium is similar to
B. pertussis but lacks some of the toxins which make its sibling so nasty. Bordetella bronchiseptica is usually a
cause of pneumonia, otitis media, and other respiratory infections in animals.

Bartonella sp are gram-negative bacteria previously classified as Rickettsiae. They cause several uncommon diseases:
cat-scratch disease, an acute febrile anemia, a chronic cutaneous eruption, and disseminated disease in
immunocompromised hosts (see Table 1: Gram-Negative Bacilli: Some Bartonella Infections).
