streptococcus iniae has emerged as an important fish pathogen over the last decade in farmed rainbow trout in iran. the main objective of this study was to evaluate the pathogenicity of s. iniae in poecilia reticulata . atotal of 60 apparently healthy p. reticulata were obtained from ornamental fish pet store and injected intraperitoneally with 1.5×10 6 cfu of bacteria. for 14 days after challe...

Streptococcosis is one of the most important diseases in aquaculture, causing high rates of mortality in fish. ArtinM, an immunostimulant obtained from jackfruit (Artocarpus integrifolia) seed extract, enhances the innate immune response. The aim of this study was to examine the action of ArtinM on neutrophil haptotaxis to the peritoneal cavity of juvenile Nile tilapia (Oreochromis niloticus) i...

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...
