[Electron microscopic demonstration of viruses in the nasal secretion from infants]

Authors examined the nasal excretion of newborn and infant for the demonstration of viruses using negative-stain-electron-microscopic technique. The nasal cavity was rinsed with physiologic saline solution and the latter was examined. The negative stain technique is a relatively quick methode for the demonstration of viruses to support the suspition of the viral aetiology of a disease until serological diagnosis is available. Authors demonstrated Orthomyxoviruses, Adenovieuses, and Herpes-viruses in the nasal cavity.
