摘要
Distribution of injected Vibrio anguillarum in body of Penaeus monodon was studied with immunohistochemical method. Bacteria could be detected throughout the experiment in some individuals; however in lymphoid tissue, gill, heart and haemolymph of all vibrio injected shrimp, the bacteria could be observed only 5 min after injection. The bacteria density in haemolymph, haemolymph of the hepatopancreas and gills decreased with time. In the lymphoid organ and heart, the bacteria density was the highest 48 h after injection, then decreased. Nodules could be formed in the heart, lymphoid organ and injection site.
