they can reactivate, causing symptomatic, even fatal, disease.


Adenoviruses (Table 51-4) were first isolated from human adenoid tissues. At present, approximately 50 serotypes of human adenoviruses have been described; however, most disease is associated with only one third of these types. Adenoviruses cause less than 5% of all acute respiratory disease in the general population, m. addition, adenovirus serotypes 40 and 41 cause gastro* enteritis in infants and young children, and other sero-type£\cause conjunctivitis and keratitis. Compromise^ hosts )may develop disseminated, multiorgan systems disease. Laboratory diagnosis is accomplished most corte monly by conventional or rapid cell culture using HEp-^ cells.
