background: zeolites containing silver ion, in combination with synthetic fibers, show antibacterial activity. objectives: the purpose of this study was to use silver zeolite indirectly as antimicrobial agents to control streptococcus iniae infection which recently has caused disease in some of rainbow trout farms in iran. methodes: in this context polyurethane foams containing silver zeolite (...

background and objective: streptococcosis/lactococcosis is the cause of high morbidity and mortality in aquaculture sector and to date a number of species of streptococcus and lactococcus genera including s. iniae, s. agalactiae, s. dysagalactiae, s. parauberis, s. feacalis, l. garvieae and l. lactis have been discriminated as the cause of disease in aquatic animals. despite the use of diagnost...

In Taiwan, the mushroom Antrodia camphorata (AC) is used for medicinal purposes, including cancer prevention and treatment. This study aimed to investigate effect of AC-supplemented diets on innate immunity disease resistance orange-spotted grouper Epinephelus coioides against two bacterial infections—Vibrio alginolyticus Streptococcus iniae. Orange-spotted groupers were fed at 0 (control), 1.5...

A 76-year-old man was admitted to our hospital with a history of fever and difficulty in moving. Blood culture at admission grew β-hemolytic streptococci, identified by biochemical testing (BD CRYSTAL GP) as Streptococcus porcinus. S. porcinus is swine-derived streptococcal species, has been reported causative bacterium female genitourinary infection. The clinical background patient did not mat...

Streptococcus iniae is a Gram-positive bacterium that is reckoned one of the most severe aquaculture pathogens. It has a broad host range among farmed marine and freshwater fish and can also cause zoonotic infection in humans. Here we report for the first time the complete genome sequence as well as the host factor-induced proteomic profile of a pathogenic S. iniae strain, SF1, a serotype I iso...

In Streptococcus iniae, lactate metabolism is dependent upon two proteins, lactate permease that mediates uptake and lactate oxidase, a flavin mononucleotide-dependent enzyme that catalyzes oxidation of alpha-hydroxyacids. A novel variant of the lactate oxidase gene, lctO, in Australian isolates of S. iniae from diseased barramundi was found during a diagnostic screen using LOX-1 and LOX-2 prim...

We evaluated the effectiveness of Streptococcus iniae vaccines prepared from formalin-killed Ž . cells and concentrated extracellular products greater than 2 kDa of a single isolate of S. iniae Ž . ARS-10 and a combination of ARS-10qARS-60 S. iniae isolates in tilapia, Oreochromis niloticus, for the prevention of streptococcal disease. Two routes of administration, intraperitoneal Ž . Ž . i.p. ...
