Studies on Lymphocystis Diseases in Sebastes schlegeli
Chun, Seh-Kyu ;
Journal of fish pathology, volume 1, issue 2, 1988, Pages 73~76
There prevailed lymphocystis disease with 1 to 2cm in size in the skin and pins of cultured Sebastes schlegeli in fish farms in Tongyoung-gun, Sanyang-myeon, Kon-ri from summer, 1987 to fall, 1988. Though there were some difference between each fish farm, this disease prevailed widely from immature fish to mature fish, less than 10cm to 30cm in body length with about 8 through 80% of infection rate. Sebastes schlegeli with the lymphocystis disease showed combined nipple-shaped mass by doubly, triply propagated lymphocystis. But the author considered that lymphocystis disease was not a direct cause of death of Sebastes schlegeli, the fish showed marked inflammation by seconary infection of pathogenic organisms.

Journal of fish pathology, volume 1, issue 2, 1988, Pages 77~85
In March 1987, a bacterial disease occured among cultured tilapia (Oreochromis niloticus), in the aquarium of Fish Pathology Laboratory of National Fisheries University of Pusan. The diseased fish showed abdominal inflamation of ascites. The causative organisms isolated from the kidney were Gram negative rods. On SS agar colonies developed within 48 hours at
. On the basis of the morphological and biochemical characteristics the organisms were identified as Edwardsiella tarda. They were sensitive to chloramphenicol, ampicilline and oxytetracycline. The pathogenicity was proved positive by intraperitoneal injection. Three kinds of antigen were prepared with E. tarda for the immune response in tilapia : i.e., by inactivating the strain with 0.4% formalin for 24 hrs at
ultrasonicating it 3 times with 5 watts for 30 seconds each time and filtrating it through millipore filter. The formalin killed antigen showed good efficacy at the injection concentration of over
cells per fish of 50g. All the immunized tilapia showed only a little agglutination titer to the three antigens. The highest survival rate was recorded in challenged tilapia immunized with formalin killed cells.

Isolation and Antimicrobial Susceptibility Testing of Edwardsiella tarda from Channa argus in Korea
Lee, Hun-Ku ;
Journal of fish pathology, volume 1, issue 2, 1988, Pages 95~101
During the period from August through October, 1988, 50 isolates of Edwardsiella tarda were isolated from 6 diseased cultured Channa argus in Dunchi island and Myung-ghi, near Pusan in Korea were examined by studying their biochemical and antibiotical reactions. The ill animals moved slowly and irregular-formed swimming at the surface of the corner. The symthoms were necrosis with hemorrhage on the body surface, head, gill region, and mouth. Some fish were observed dropsy of the belly. The bacteria grew slowly on Double Salmonella-Shigella agar, 24h, at
to form relatively small size (2mm diameter), smoothed and convexed form with transient or black in center of the colonis. They gave negative reactions to Voges-Proskauer, Simmon's citrate, urea, KCN (in growth), gelatin, arginine dehydrolase, phenylalanine deaminase and many sugars. The isolates showed positive reactions to
(in KIA agar), indol, Methyl-Red, motility, lysine and ornithine decarboxylase, and gas from glucose. 8 drugs tested as chloramphenicol, colistin, gentamicin, kanamycin, lincomycin, nalidixic acid spectinomycin, and tetracycline. All cultures were resistant to colistin, lincomycin and spectinomycin respectibly, but sensitive to kanamycin and nalidixic acid. Three strains showed resistance to chloramphenicol and 2 isolates among them were resistant to two drugs(gentamicin and tetracycline), coincidentally.
The Rapid Diagnosis of
-Haemolitic Streptococcus sp. by Immunoperoxidase Method

Journal of fish pathology, volume 1, issue 2, 1988, Pages 103~110
For the rapid diagnosis of bacterial diseases of cultured fishes, the immunoperoxidase method was applied to the detection of
-haemolitic Streptococcus sp. strain KST-2 isolated from tilapia(Oreochromis niloticus). The suitability of field analysis and the sensitivity of the immunoperoxidase method was compared with those of the counterimmunoelectrophoresis(CIE) and the immunodiffusion(ID). Results of testing cross-reactivity which did not indicate any cross reactivity with other fish pathogens, this method was specific to Streptococcus sp. The sensitivity of this method was
which was at least
times greater than the CIE and
times greater than the ID. The immunoperoxidase method was more suitable for field application and more sensitive than other diagnostic techniques tested on this study.
Studies of Thelohanellus infection in carp, Cyprinus carpio. I. Experimental induction of Thelohanellosis.
Chun, Seh-Kyu ; Park, Soo-Il ; Choi, Dong-Lim ;
Journal of fish pathology, volume 1, issue 2, 1988, Pages 111~116
There occurred a large quantity of death of the cultured carp (Cyprinus carpio) in net pens in Lake Taechong and Lake Chungju(Chungcheongbuk-do) from July through Sep., 1987. The carp were two-year-old and 500g to 2,500g in body weight. As a result of biopsy of dying carp, 1 through 10 egg-shaped giant cysts with 12 through 60mm in diameter were observed in their intestine per one carp. The author suggested that the carp were died from blockade of intestinal tract and following enteritis by the giant cysts. The giant cysts were filled with numerous mature Thelohanellus genus spores confirmed to Thelohanellus kitauei after following examination. In this case the author could find out this disease was spread by transverse infection following infestation in net pens of fingerling fish farms.

Influence of Lidocaine as an Anaesthetic for Marine Fishes
Park, In-Seok ; Kim, Jong-Man ; Kim, Yeon-Hwan ; Kim, Dong-Soo ;
Journal of fish pathology, volume 1, issue 2, 1988, Pages 123~130
General anaesthetics have been usually used for a long time because handling and transportation of live fish constitutes an important aspect in fisheries science. Numerous investigations, however, have shown that the majority of fish anaesthetics cause strong toxic effect to marine fishes. Therefore, less toxic and more effective anaesthetics are essential for marine fishes. Lidocaine belongs to a group of anaesthetics which are used as a local anaesthetic in human medicine. This chemical was tested for 11 commercially important marine fishes. Anaesthetic effects were clearly dose dependent and acute or chronic toxicities were not observed within clinical doses. The recovery time in the tested fish after anaesthetization was 3 to 4 minutes.
UPTAKE OF COBALT BY GOLDFISH(Carassius auratus)

Journal of fish pathology, volume 1, issue 2, 1988, Pages 131~134
Radiocobalt was used as tracer to study the uptake of cobalt by fish either from water or food source, respectively. Four groups of goldfish were exposed to
-labelled water under 4 different temperatures, while another four groups were fed labelled feed pellets at
. Results indicate that water temperature has no significant effect on the uptake of cobalt from water. The uptake from water is quite a slow process since the cobalt uptaken from water reached 0.0006% of available activity at best on the 13th day of exposure. The uptake from a labelled feed source showed a linear increase with time over the period of ninety days. On the 90th day of experiment the percentage of available activity consumed seemed to be approaching an equilibrium point at roughly 12% of the total activity fed to the goldfish.
