Attempts to analyse Anguillicola crassus infection and the humoral host response in eels (Anguilla anguilla) of Lake Balaton, Hungary
Since the introduction of Anguillicola crassus into Europe, anguillicolosis has been a considerable problem in several countries. From 1991, periodical eel mortality occurred in Lake Balaton, Hungary. However, eels with a worm burden of 20 to 50 parasites did not show severe swimbladder lesions, whi...

Since the introduction of Anguillicola crassus into Europe, anguillicolosis has been a considerable problem in several countries. From 1991, periodical eel mortality occurred in Lake Balaton, Hungary. However, eels with a worm burden of 20 to 50 parasites did not show severe swimbladder lesions, which observation cast doubts on the primary aetiological role of the parasite in the eel kill. In order to study the pathology of the infection, from the spring of 1996 until October of the same year, 51 eels were collected from two regions of Lake Balaton and examined for swimbladder changes. To detect humoral antibodies, an enzyme-linked immunosorbent assay (ELISA) was performed, using cuticular-oesophageal worm antigen. The results of the test show the applicability of the method. However, no direct correlation was found between antibody levels or the intensity of infection and the swimbladder lesions. The low level of specific antibodies and the increasing severity of swimbladder changes in the autumn suggest that parasite-induced immunity is insufficient to prevent reinfection. |
