Immune response of the Almaco jack (Seriola rivoliana) against the infestation with Neobenedenia sp. in three cultivated temperatures

“…These can induce the production of reactive oxygen metabolites and complementary factors with well-known adverse effects in monogeneans (Lindenstrom In addition, given that the increase in the parasites intensity lead to a reduction of the overall immune response, we considered that the proin ammatory response appears to be involved in repairing the skin damage caused by the parasites rather than to eliminate the parasite. The skin healing process can avoid entrance for other pathogens present in the culture systems such as viruses and bacteria that could lead to a secondary infection (Leong and Colorni 2002). Based on this we considered that the immune response mediated by the IL-1β is a generalized response of sh against ectoparasites, that supports the conceptual model proposed by Buchmann (1999).…”

Proteomic profile and protease activity in the skin mucus of greater amberjack (Seriola dumerili) infected with the ectoparasite Neobenedenia girellae — An immunological approach

“…Neobenedenia girellae is a monogenean ectoparasite with a wide host range distributed in warm waters worldwide, with greater amberjack especially susceptible to this infection when reared in sea cages [19]. High parasite loads in greater amberjack induce fasting, stress-related changes in color appearance, erratic swimming, and a scratching tank fixtures, which results in the development of ulcers and subsequent opportunistic bacterial infections [20]. Some studies about the mechanical damage of N. girellae to greater amberjack skin [21] and how this infection affects the mucus glycoproteins and serine proteases profile [22,23] are available.…”
