Abstract

The dissemination of dengue (DEN) 3 virus in parenterally infected female Aedes aegypti mosquitoes was studied immunocytochemically. Antigen was first detected in fat body cells near the thoracic site of virusinoculation. The intussuscepted foregut, salivary glands and nervous tissue were the first major tissues infected. Nervous tissue appeared to be the primary site of amplification. Muscles, tracheae, Malphigiantubules and the posterior midgut did not become infected. The only part of the reproductive system to be infected was the calyx (71% of specimens 16-22 days post-infection) consistent with low rates of vertical transmission. After 7 days post-inoculation the salivary glands of 100% of the specimens examined were infected. Virus dissemination was slow and the most common sequence of infection following intrathoracic inoculation was as follows: thoracic fat body, intussuscepted foregut,salivary glands, cardial epithelium, thoracic ganglion, brain, compound eye, anterior midgut, intermediate midgut/anterior abdominal ganglia, and calyx/hindgut/posterior abdominal ganglia, Fat body and intussuscepted foregut tissues lost infections after 16 days post-inoculation.
