发布时间：2023-04-28 - 摘要：Left eyed flounders Paralichthys olivaceus, were inoculated with inactivated Vibrio anguillarum vaccine via intramuscular injection to analyze level of cellular immune responses induced by the immunogen.The vaccinated as well as control fish were serially sampled forblood cells 2, 3, 4, 5 weeks post immunization to evaluate phagocytosis activity. Changes of phagocytic index (PI) and phagocytic percentage (PP) determined by measurement of ingesting Staphylococcus aureus were observed with Wright’stain.Results showed that phagocy tosis activity began to increase from 2 weeks post immunization.There isare statistically significant differences in PI and PP(P<0.05) between vaccinated and control fish.The redcell phagocytosis of left-eyed flounders described in the present study for the first time indicates red cellplays an important role not only in respiratory function but also in immune function.关键词：INACTIVATED VIBRIO ANGUILLARUM VACCINE, PARALICHTHYS OLIVACEUS,PERIPHERAL BLOOD CELLS

发布时间：2023-04-28 - 摘要：Edwardsiella tarda is a gram-negative pathogen with a wide host range,which can infect many kinds of fish and lead to extensive losses in aquaculture.The pathogenesis of E.tarda is not clearly understood.So far as we know its virulence factors include hemolysins,chondroitinases,dermatonecrotic exotoxic substances,catalases,etc. The latest study indicates that the type three secretion system(TTSS) ofE.tarda is tightly associated with bacterial pathogenesis. The gene structure of the TTSS has been elucidated and relational research is on the way.

发布时间：2023-04-28 - 摘要：Quorum Sensing is a mechanism in which bacteria coordinate the expression of certain genes in response to their poulation density.Many marine vibrios are important pathogens in aquaculture and many pathogenic vibrios are found to control the expression of virulence factors by quorum sensing system. The frequent use of antibiotics is leading to the rapid development of resistance,There is an urgent need to develop alternative ways to control infections caused by bacterial pathogens in aquaculture.Disruption of bacterial quorum sensing has been proposed as a new anti-infective strategy. This article summarize the quorum sensing systems in marine vibrios,the modes of signal interference and their potential applications in aquaculture.

发布时间：2023-04-28 - 摘要：The effects of Prorocentrum donghaiense,Karenia mikimotoi,Alexandrium catenella,the causative species of Harmful Algal Blooms in the East China Sea,on the survival and growth of Neomysis awatschensis and Artemia salina were investigated.And the toxicity of eleven strains of Alexandrium----A.lusitanicum(AL-1)、A.minutum(AM-1)、A.spp.(A-K)、A.tamarense(ATHK,ATCI02,ATCI03,AT5-1,AT5-3,AT-6)、A.affine(AS-1,AC-1) to the two above organisms were compared. The results showed that P.donghaiense and K.mikimotoi had no adverse effect on the survival and growth of N.awatschensis and A.salina at 96h.However,the survival rate of N.awatschensis and A.salina declined linearly with the increasing density of A.catenella,and the 96h LC50 for N.awatschensis and A.salina was 4500 and 460 cells/mL,respectively, Five strains of Alexandrium----A.spp,A.lusitanicum (AL-1),A.tamarense(AT5-3,AT-6) and A.affine (AS-1)at the density of 4000cells/mL and 96h had no adverse impacts on N.awatschensis. But other six strains of Alexandrium a.Tamarense(AT5-1,ATHK,ATCI02,ATCI03),A.affine(AC-1) and A.minutum(AM-1)decreased the survival fate of N.awatschensis significantly. Two strains of Alexandrium----A.lusitanicum(AL-1) and A.tamarense(AT-6),at the density of 500cells/mL. had no adverse effects on A.salina in 96h;while the other Alexandrium strains all had adverse effeets on the survival of a.salina, A.salina could increase its length with the increasing density of P.donghaiense,K.mikimotoi and A.luxitanicum. The results indicate that P.donghaiense and K.mikimotoi have nio significant effect on the survival of crustaeean zoop lankton in a short period. But several Alexandrium specised/strains could influence the survival of crustacean zooplankton likely by non-PSP substances. A.salina is shown to be more sensitive than N.awatschensis as test organisms to harmful species.
