Figure 8From: Sensitivity and permissivity of Cyprinus carpio to cyprinid herpesvirus 3 during the early stages of its development: importance of the epidermal mucus as an innate immune barrierHistological structure of skin epidermis during the early stages of carp development. At the indicated days post-hatching, carp were harvested and either left untreated (Control, panels a to e) or treated for removal of the epidermal mucus (Mucus, panels f to j). The fish were then euthanized and processed for histological examination of the skin epidermis. The numbers in the upper panels represent the thickness of the epidermis (mean ± SD, based on 15 measurements). Histological structures were identified for the samples collected 35 days post-hatching (panels e and j): 1, mucus; 2, epidermis; 3, basement membrane (arrow head); 4, dermis and dorsal muscles. Scale bar = 25 μm.Back to article page
