We study members of the Gram-negative genus\u00a0<i>Bordetella<\/i>\u00a0(which includes\u00a0<i>B. pertussis<\/i>, the causal agent of whooping cough) as models because they are relatively easy to grow, they are genetically tractable, and\u00a0<i>B. bronchiseptica<\/i>\u00a0(a close relative of\u00a0<i>B. pertussis<\/i>) has a broad host range that includes many animals commonly studied in the laboratory, such as rabbits, rats and mice.
