Abstract

Analyses of bacterial genes expressed in response to the host environment provide clues to understanding the host-pathogen interactions that lead to the establishment of infection. In this study, a novel method named In Vivo Expressed-Tag ImmunoPrecipitation (IVET-PI) was developed for detecting genes expressed in bacteria that are recovered in a small numbers from host tissues. IVET-IP was designed to overcome some drawbacks of previous similar methods. We applied IVET-IP to Bordetella bronchiseptica colonizing rat trachea and identified 173 genes that were expressed in the bacteria over the entire course of an infection. These gene products included two transcriptional factors that are involved in the expression of filamentous hemagglutinin, adenylate cyclase toxin, and major virulence factors for the bordetellae. We consider that this method might provide novel insight into the course of Bordetella infection.
