Silkworm salivary glands are not susceptible to Bombyx mori nuclear polyhedrosis virus

L. A. Dourado, Ribeiro, L. F. C., Brancalhão, R. M. C., Tavares, J., Borges, A. R., and Fernandez, M. A., Silkworm salivary glands are not susceptible to Bombyx mori nuclear polyhedrosis virus, vol. 10, pp. 335-339, 2011.

A nuclear polyhedrosis virus isolated from infected Bombyx mori, BmNPV, was used to inoculate silkworms to determine salivary gland cell susceptibility. The salivary gland was removed from infected silkworms at different times post-inoculation and examined by light microscopy. The salivary gland cells did not exhibit any signs of BmNPV infection; however, fat body and tracheal cells, used as positive controls, showed characteristic cytopathological changes caused by BmNPV infection, which confirmed inoculum viability.
