Abstract

Bronchiolitis due to the respiratory syncytial virus (RSV) is the most common cause of lower respiratory tract infection in the first year of life. It has been suggested that RSV infection may cause subsequent asthma, but a mechanism for this relationship has not been demonstrated. Studies examining the presence of airway reactivity in infants with RSV bronchiolitis are limited by our inability to administer provocative agents such as histamine to such ill infants. This makes a small animal model of this condition a useful tool in which to investigate the pathophysiology of RSV bronchiolitis. We, therefore, evaluated airway responsiveness in vivo and airway morphometric changes in 20 guinea ..
