Abstract

Abstract Koi Herpesvirus (KHV) was formerly known as Cyprinid herpesvirus-3 (CyHV-3) and carp nephritis interstitial and necrosis gill virus (CNGV) is a virus that infects common carp and koi (Cyprinus carpio and C. carpio koi) in farmed and wild population. KHV cause disease at a temperature of 18-25 °C with mortality rate of 80-90 % in fry and adult fish. Currently KHV also detected in tilapia from the results of monitoring in the field. The presence of KHV in tilapia can occur as a result of maintenance in cages adjacent to the infected carp. KHV diagnostic method currently based on case definition and PCR (Polymerase Chain Reaction) detection. The basic concept of PCR is one DNA molecule is used to produce two copies, then four, then eight and so forth through multiplication by polymerase. PCR results sometimes indicated the presence of a faint band caused a low amount of virus, so it is necessary to investigate the presence of KHV DNA in tilapia using different doses of infection. This study aimed to determine the KHV infectivity in nile tilapia were infected by artificially infection and determine dose KHV infection that can infect nile tilapia. The study design used true experimental with with the presentation of descriptive data. Dose of viral infection are 1 ID50, 10 ID50, 100 ID50 and 1000 ID50. The results showed that no clinical symptoms of KHV infected in nile tilapia. The results of electrophoresis of PCR products showed that the mucus of nile tilapia were infected with a 1000 ID50 immersion dose showed thin bands. The same results are also shown in the gill of nile tilapia infected by gill spray at 1000 ID50 dose. Fish were infected by injection, KHV was not detected in mucus, gill, kidney and liver. The results above show nile tilapia cannot be infected by KHV on various treatment

Abstract

Abstract KHV is a viral disease in goldfish and Koi Fish (Cyprinus carpio) is a highly contagious, infecting all ages or sizes of fish and aquaculture systems. This disease results in mortality between 80% - 100% of the total fish population, with an incubation period of between 1-7 days. KHV infection triggered by a drop in ambient temperature so it is referred to as a virus that attacks when cold (a cold virus). The disease attacks the temperature range of 18-28 ° C and can cause death. This virus attacks can occur at any age of the fish ranging in size from the seed to the parent. The most prominent clinical symptoms due to KHV infection is the sudden death 1-2 days after infection. Other clinical symptoms are necrosis of the gills, sunken eyes, bleeding at the gills, hemorraghe, excess mucus production in the body, and secondary bacterial infections or parasitic infestations. Streptavidin biotin immunohistochemical method was applied to the study of cells and tissues by staining imunostaining. Technique of determining the existence of (location) antigen (target protein) in tissue using antigen-antibody reaction that begins with histotenik procedure is the procedure of making tissue sections (histology). This method has high sensitivity and fast so that it can be applied to the detection of KHV antigen in tissues of fish Tilapia (Orechromis niloticus). This study aims to determine the presence of KHV antigen in tilapia gills after infection. The method used in this study is the experimental method. Dose of virus titer used was 1 ID50, ID50 10, 100 ID50, ID50 1000. The results showed that the Streptavidin Biotin immunohistochemical examination imunopatologi able to detect KHV virus Ag in the gill tissue of tilapia (Oreochromis niloticus) were infected with different doses. In all treatments showed on all the gills are KHV antigen is indicated by the presence of a golden brown color on the gill epithelium. Advised Streptavidin biotin immunohistochemistry test was applied to the detection of the presence or absence of fish-carp KHV carrier as a routine control program and control, including the prevention and outbreak of KHV in Indonesia, because of KHV were attacked in tilapia was persistent and did not show clinical symptoms

Abstract

Abstract African catfish (Clarias gariepinus) is a type of freshwater fish consumption with elongated body and smooth skin. Bacterial disease that often strikes African catfish and can cause death as well as a cause of primary infection is A.hydrophila. Bacterial infection may be one cause of the synthesis of lipid peroxidation which is an indication of the emergence of free radicals. And the end result of lipid peroxidation is malondialdehyde. Sprouts are the new little plants grow from seeds planted beans. Green bean seed germination will enrich vitamins including vitamin E, green beans or α-tocopherol. Vitamin E in maintaining the stability of the plasma membrane and protects the cell structure against damage caused by free radicals is by blocking the reaction initiation and propagation of lipid peroxidation reactions interrupt. Data analyze of this research was used Varian Analyze (ANAVA) and to found the lowest level was used Duncan Test. The average yield of malondialdehyde levels in the negative control treatment is 0.0386 ng / 100 mg mass, positive control (1 ml Aeromonas hydrophila 105 cfu per 5 liter) is 0.0962 ng / 100 mg mass, sprout extract treatment (0 , 1 ml per fish) is 0.05 ng / 100 mg mass, germination and pollen treatment Aeromonas hydrophila is 0.0626 ng / 100 mg mass. From these results indicate that the highest levels found in the positive control treatment while the lowest levels found in the negative control. These results also suggest that decreased levels of malondialdehyde using pollen germination is very significantly different with P < 0,01.
