Abstract__ Background Swine barn air contains endotoxin and many other noxious agents. Single or multiple exposures to pig barn air induces lung inflammation and loss of lung function. However we do not know the effect of exposure to pig barn air on inflammatory response in the lungs following a secondary infection. Therefore we tested a hypothesis that single or multiple exposures to barn air will result in exaggerated lung inflammation in response to a secondary insult with Escherichia coli LPS E. coli LPS . Methods We exposed .
