title: Update on bacterial pneumonia and pleuropneumonia in the adult horse.
abstract: Bacterial infections of the lower respiratory tract in adult horses occur when bacteria from the nasopharynx reach the lower airways and overwhelm normal defense mechanisms. Although Streptococcus equi subsp zooepidemicus is the most commonly isolated bacterial species, mixed infections are possible. Tracheobronchial aspiration for microbiologic culture and sensitivity is suggested in cases presenting with severe clinical signs or not responding to treatment. Early intervention and appropriate antimicrobial selection results in a good prognosis for both survival and return to athletic function in most horses.
