Isolation and pathological diagnosis of measles virus by cytopathic effect (CPE) and indirect fluorescence assay. Vero-SLAM cells were infected with control cell culture media (A, D) and virus collected from throat swabs (B, C) for 72 h. Cells infected with virus collected from throat swabs showed obvious CPE (B) while cells infected with control media were normal (A). Indirect fluorescence assay was performed on cells infected with control virus and throat swab material. Viral infected cells showed peripheral green fluorescence staining (C) which was absent in control cells (D).
