Morphogenesis of the nodamura virus in the larbae of the lepidopteran Galleria mellonella (L.).


The pathogenesis and morphogenesis of the Nodamura virus, an insect picorna- virus which can also infect vertebrates such as newborn mice, are described in the larvae of G. mellonella. Examination of thin sections of muscle, salivary and moulting glands, hemocytes adipose tissue and hypodermis of the infected larvae of G. mellonella shows in the cytoplasm the accumulation of viral particles either dispersed or in a stringlike or paracrystalline array. These arrays of virions can be within membrane- bound vesicles. Helical filaments of 110 A of diameter can be observed inside the basal membranes and later in the cytoplasm, in relation to the infection of muscular or adipose tissues. The morphogenesis of Nodamura virus in G. mellonella or in suckling mice is very similar to that of the Coxsackie A virus observed in the mouse.
