Silurus asotus lectin (SAL) is a member of the rhamnose-binding lectin (RBL) family, and recognizes globotriaosylceramide (Gb3) on the cell surface of Burkitt's lymphoma cell lines, such as Raji and Daudi cells. The variation of gene expression in the treatment of both cells with SAL was analyzed using the differential display (DD) method with combination of 16 kinds of arbitary primers and 3 k...

Irrigation channels around paddy fields have been drastically improved over the past several decades in Japan. This has been accomplished exclusively by covering all the sides of channels with concrete. Although it is conventionally accepted that channel improvement has deteriorated quality of spawning and nursery sites for fish, to date, there is little evidence to support this claim. We exami...

Three iridovirus-like agents associated with systemic infections in fish were examined by electron microscopy, gel electrophoresis of virion polypeptides and serological cross reactions with hyperimmune rabbit sera. The virus associated with epizootic hematopoietic necrosis (EHN) of redfin perch Perca fluviatilis in Australia, the virus from sheatfish Siluris glanis in Germany and a recently is...

An acute infectious disease of northern sheatfish (Silurus soldatovi) was found in a commercial aquaculture pond Tianjin, China. Herein, two dominant bacterial strains were isolated from naturally diseased and identified as Aeromonas veronii Vibrio cholerae. Seven healthy seven fish that collected the used for gut microbiota analysis by high-throughput 16S rRNA gene sequencing. The α-diversity ...
