Detection of the bunyavirus Germiston in VERO and Aedes albopictus C6/36 cells by in situ hybridization using cDNA and asymmetric RNA probes.
Using Germiston virus infected vertebrate (VERO) and invertebrate (Aedes albopictus C6/36) cells, paraformaldehyde-glutaraldehyde fixative allowed the best preservation of cellular morphology and the highest hybridization signals with cDNA and asymmetric RNA probes against the viral S segment. Asymmetric RNA probes always gave higher sensitivity and better specificity of in situ hybridization than the nick-translated symmetric DNA probe in both vertebrate and invertebrate cells. The study of Aedes albopictus C6/36 cells persistently infected with Germiston virus showed that only a small number of cells contained the S segment, and that the replication and transcription of the S segment took place in the cytoplasm of acutely and persistently infected cells.
