Special Issue Information

Dear Colleagues,

Fish disease diagnostics are constantly and rapidly evolving. New pathogens are continually being discovered, and our understanding of historically known etiological agents is growing. This is due in particular to the use of increasingly sophisticated diagnostic techniques, allowing us to obtain results that provide more information compared with the previously used methods. On this path, omics techniques, already widely applied in several sectors of veterinary medicine, are increasingly being used in the field of fish disease. These techniques allow us to obtain more information on emerging pathogens, to track disease outbreaks, and to review the taxonomy of microorganisms that are difficult to identify. The progressive reduction in the costs of these technologies is facilitating their diffusion and routine application in diagnostic laboratories.

Therefore, our Special Issue aims to focus on the application of omics techniques in the diagnosis and study of the pathogens of aquatic organisms (fish and shellfish). Articles for submission should concern the application of these methods for the identification, characterization and control of viruses, bacteria, fungi and parasites that can affect wild and/or farmed fish, molluscs and crustaceans. Studies regarding the comparison of omics techniques with traditional assays will also be taken into consideration, in order to highlight the limits and potential of the various diagnostic methods.

The European eel (Anguilla anguilla) is a catadromous species that inhabits the rivers of the Adriatic watershed in Croatia. It is a critically endangered fish species, according to the IUCN, due to its declining abundance in European rivers caused by overfishing and trafficking and by diseases caused by nematodes, pathogenic bacteria and viruses. An illegal parcel of glass eels was confiscated at the Zagreb Airport and was intended to re-populate Croatian rivers. Barcoding was employed to determine species affiliation, and a thorough health check was carried out. This study reports the evaluation of gross lesions, histological findings, and EVEX virus isolation and identification. Since the confiscated glass eels were of unknown origin and given the serological and genetic similarities of EVA and EVEX, we designed primers and probes for almost whole genome sequencing to elucidate the origin of glass eels based on viral phylogeny. Bayesian phylogeny showed that the isolated strain had the most common ancestor with a Danish isolate and likely evolved from the French isolate of EVEX. These findings are discussed in light of the divergence of recently isolated strains and their possible contribution to the decrease of the abundance of the European eel in European waters.
