[Electron microscopic diagnosis of viral diseases]

Rotaviruses were detected in 58 among 194 children with nonbacterial gastroenteritis whose feces were examined by direct electron microscopy and immune electron microscopy (IEM). Identification of Coxsackie B viruses isolated from patients with infectious-allergic myocarditis by IEM and the neutralization tests gave similar results (Coxsackie B6). Besides, IEM detected the accompanying virus types.
