(a) Schematic diagram of Peste des petits ruminants virion structure (adapted from Banyard et al., 2010). The PPRV glycoproteins (F and H) are embedded within the viral envelope. The M protein lines the inner surface of virus envelope. The ribonucleoprotein complex is composed of N, P and L proteins in association with the RNA genome. (b) Electron micrograph of peste des petits ruminants nuclocapsid in the cytoplasm of an infected cell. The viral RNA, completely encapsidated in the viral N protein has a herring-bone like appearance (arrow).
