Abstract

The pathogen-free, colostrum-deprived pigs infected intranasally with a lung-isolated enterovirus showed pneumonitis in the early stage of infection and viremia was recognized 2 days after infection (DAI). Specific fluorescence appeared clearly only in the lungs of the pigs. The fluorescent cells consisted of the epithelial cells of bronchus, alveolar septum and possibly the endothelial cells of alveolar septal capillary. Appearance of the fluorescent cells was markedly characterized by the local existence in the lung. Fluorescence appeared in the bronchial epithelial cells only 2 and 8 DAI, when alveolar septum was rich in fluorescent cells. Rectal temperature also showed 2 peaks corresponding to the appearance of fluorescence in the lung. No fluorescence was seen in the other organs.
