Protective efficiency of an inactivated vaccine against Streptococcus iniae in olive flounder, Paralichthys olivaceus
Streptococcus iniae is a causative agent of hemorrhagic septicemia in olive flounder, Paralichthys olivaceus, in Korea, resulting in serious economic losses. As a preventive measure, M VAC INIAE (Mastuken, Japan) was prepared from the S. iniae F2K strain and tested against the SI-36 strain prevalent on flounder fish farms on Jeju Island, Korea. F2K had a serotype of 38 (–) and SI-36 38 (+). The...
متن کاملDevelopment of a multiplex PCR assay to detect Edwardsiella tarda, Streptococcus parauberis, and Streptococcus iniae in olive flounder (Paralichthys olivaceus)
A multiplex PCR protocol was established to simultaneously detect major bacterial pathogens in olive flounder (Paralichthys olivaceus) including Edwardsiella (E.) tarda, Streptococcus (S.) parauberis, and S. iniae. The PCR assay was able to detect 0.01 ng of E. tarda, 0.1 ng of S. parauberis, and 1 ng of S. iniae genomic DNA. Furthermore, this technique was found to have high specificity when t...
متن کاملCloning and expression of partial Japanese flounder (Paralichthys olivaceus) IgD.
The cDNA sequence of the Japanese flounder (Paralychthys olivaceus) IgD has been previously reported (GenBank accession no. AB052658) and this was followed by the detection of IgD mRNA expression in some flounder organ tissues. However, it has not been determined whether the flounder IgD gene is virtually expressed into IgD protein. To characterize the flounder immunoglobulins utilized in eluci...
متن کاملThe mechanism of transcriptional regulation of Müllerian inhibiting substance in Japanese flounder (Paralichthys olivaceus)
müllerian inhibiting substance (miS), also known as anti-müllerian hormone (amh), is a glycoprotein belonging to the transforming growth factor ß superfamily. In Japanese flounder (Paralichthys olivaceus), a teleost fish that has XX(female)/XY(male) sex determination system, mis mRNA is expressed in the somatic cells of the gonads during gonadal sex differentiation. However, the mechanism of tr...
متن کاملIsolation and characterization of Streptococcus sp. from diseased flounder (Paralichthys olivaceus) in Jeju Island
Streptococcus sp. is gram-positive coccus that causes streptococcal infections in fish due to intensification of aquaculture and caused significant economic losses in fish farm industry. A streptococcal infection occurred from cultured diseased olive flounder (Paralichthys olivaceus) in May, 2005 at a fish farm in Jeju Island, Korea. The diseased flounder exhibited bilateral exophthalmic eyes a...
