Abstract:
PURPOSE: An inactivated vaccine for preventing vibrio harveyi infection, containing vibrio harveyi HN strain as an antigen is provided to reduce mortality of fishes and to enhance productivity of fishes. CONSTITUTION: A Vibrio harveyi HN(deposit number KCTC 11705BP) strain is isolated from flatfishes with vibrio harveyi infection. An inactivated vaccine for preventing vibrio herveyi infection contains the Vibrio harveyi HN(deposit number KCTC 11705BP) strain as an antigen. The vaccine further contains inactivated Streptococcus parauberis strain. A method for manufacturing the vaccine comprises a step of culturing the Vibrio harveyi HN(deposit number KCTC 11705BP) strain and inactivating. The medium for culturing the strain contains 50-200 umol of 2,2'-dipyridyl.
Abstract:
A method for preparing a mixture vaccine is provided to obtain the vaccine which is able to prevent Edwardsiellosis and beta-hemolysis streptococcal disease at the same time by one shot injection so that the health fish can be maintained. The method comprises the steps of: (a) after adding 20% glycerin to Edwardsiella tarda FP2018 and Streptococcus iniae JSL 0208, preserving it at a temperature of -85 deg.C; (b) after inoculating the preserved Edwardsiella tarda FP2018 and Streptococcus iniae JSL 0208 in a BHI(brain heart infusion) solid culture medium in which 1% of NaCl is added, culturing it at a temperature of 25 deg.C for 18-24 hours; (c) after respectively suspending cultured strains in sterile saline solution to prepare a suspended solution having the absorbance of 0.5, inoculating 5 ml of each of the obtained solution to 1 liter of a BHI liquid culture medium in which 1% of NaCl is added; (d) culturing each of the strains-inoculated each Erlenmeyer flask with mixing it in a shaking incubator at a temperature of 25 deg.C with the speed of 150 rotation per minute for 24 hours; (e) after respectively putting 37% formaldehyde in each of the strain culture solution to have the formaldehyde concentration of 0.4% and leaving it at room temperature for 1 hour, leaving it at 4 deg.C for 24 hours to inactivate each of the strains; (f) after centrifuging each of the inactivated strain culture solution with the speed of 6,000 rotation per minute for 20 minutes and measuring wet weight thereof, diluting it in sterile saline solution in which 0.02% of sodium azide is added to have the wet weight of 100mg/ml and storing it at a temperature of 4 deg.C; and (g) mixing a vaccine for Edwardsiellosis and a vaccine for beta-hemolysis Streptococcal disease in a ratio of 1:1.
