Immuno-histochemical determination of humoral immune markers within bacterial induced granuloma formation in Atlantic cod (Gadus morhua L.)

Autor: D. Groman, B K Gudmundsdóttir, Bergljót Magnadóttir

Publikováno v: Fish & Shellfish Immunology. 34:1372-1375

In this study the involvement of several humoral immune parameters of Atlantic cod (Gadus morhua L.) were studied in granuloma formed as a result of infection by Aeromonas salmonicida ssp. achomogenes. The results showed a clear association of immune

Virulence properties of Moritella viscosa extracellular products

Autor: Thorunn Björg Gudmundsdóttir, B K Gudmundsdóttir, Bryndis Bjornsdottir

Publikováno v: Journal of Fish Diseases. 34:333-343

Moritella viscosa is the causative agent of winter ulcer disease of marine fish. Knowledge of its pathogenicity is limited and there are no reports comparing the virulence properties of a collection of bacterial isolates. The in vivo and in vitro vir

Analysis of effects induced by a pollock protein hydrolysate on early development, innate immunity and the bacterial community structure of first feeding of Atlantic halibut (Hippoglossus hippoglossus L.) larvae

Autor: R. Hermannsdottir, Rannveig Björnsdóttir, Sjofn Sigurgisladottir, B K Gudmundsdóttir, Heiddis Smaradottir, Jonina Johannsdottir

Publikováno v: Fish & Shellfish Immunology. 27:595-602

A pollock protein hydrolysate was used for enrichment of the live feed offered to halibut larvae from the onset of exogenous feeding and the effects of treatment on selected innate immune parameters studied. The effects of treatment on the bacterial

Publikováno v: Journal of bacteriology

Infections by the bacterium Aeromonas salmonicida subsp. achromogenes cause significant disease in a number of fish species. In this study, we showed that AsaP1, a toxic 19-kDa metallopeptidase produced by A. salmonicida subsp. achromogenes , belongs
