Primary pneumonic vs cultured Y. pestis


ABSTRACT: Although pneumonic plague is the deadliest manifestation of disease caused by the bacterium Yersinia pestis, there is surprisingly little information on the cellular and molecular mechanisms responsible for Y. pestis-triggered pathology in the lung. Therefore, to understand the progression of this unique disease, we developed an intranasal mouse model of primary pneumonic plague. Mice succumbed to a purulent multifocal severe exudative bronchopneumonia that closely resembles the disease observed in humans. In order to assess the adaptation of Y. pestis to a mammalian environment, we employed DNA microarray technology to analyze the transcriptional responses of the bacteria during interaction with the mouse lung as compared to bacteria cultured in vitro. Keywords: Infectious expression analysis
