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.

Abstract:
A method for controlling aquatic fungi and fish pathogenic bacteria of cultivated fish is provided to improve productivity of the cultivated fish by effectively controlling the aquatic fungi and fish pathogenic bacteria using a proper amount of an extract of Opuntia ficus-indica var. saboten Makino and provide safe aquatic products to consumers by using environment-friendly and harmless Opuntia ficus-indica var. saboten Makino extract. To exterminate aquatic fungi of fish eggs, the fish eggs are treated with 50-80 ppm of a hydrolysis fraction of Opuntia ficus-indica var. saboten Makino for 30 minutes every 3 days until the fish eggs become germinated egg. To exterminate aquatic fungi of fish, the fish is treated with 200 ppm of the hydrolysis fraction of Opuntia ficus-indica var. saboten Makino for 2 hours per day one or two times. To treat and prevent fish pathogenic bacteria of cultivated fish, 0.1% hydrolysis fraction of Opuntia ficus-indica var. saboten Makino is absorbed into an expansion pellet and the expansion pellet is administered into the cultivated fish for 4 weeks.
Abstract:
A gene of a parasite causing death of Halocynthia roretzi and a method for diagnosing a parasite are provided to obtain a living organism that causes perishing of Halocynthia roretzi, and to diagnose a parasite by using a part of 18S rDNA fraction causing perishing of Halocynthia roretzi. A method for diagnosing a parasite includes the steps of: separating the entire nucleic acid from Halocynthia roretzi; performing PCR reaction by having the separated nucleic acid as a template and having a front primer and a reverse primer having a partial sequence of 18SrDNA fraction having a nucleotide sequence of sequence number 1 as a primer pair; and checking the size of the product of the PCR reaction by gel electrophoresis and comparing the size of the aforesaids product with the size of the product that is anticipated from the used primer pair.
