Abstract: Negative-stained intact yellow head virus (YHV) was an enveloped bacilliform particle measuring 40-50 × 175-210 nm with spike-like projections measuring 7-9 nm. The space between projections was 4-7 nm. YHV nucleocapsid was rod-shaped, measuring 35-40 × 160-200 nm, and the RNA genome had 40-50 turns in a helical structure. YHV infected both stromal matrix cells and haemocytes in the lymphoid tubule wall. The patterns of localisation of viral particles were similar in both cells. The fully enveloped viral particles were detected at the cell membrane, endosome, rough endoplasmic reticulum, Golgi complex and secretory vesicles, and virions were exocytosed at the cell membrane. In the case of severe infection, unenveloped viral particles could be detected in the cytoplasm, and they might be released by general breakdown and lysis of the highly infected cells.
