Streptococcus iniae is a major fish pathogen that can also cause human bacteremia, cellulitis and meningitis. Screening for and identification of protective antigens plays an important role in developing therapies against S. iniae infections. In this study, we indicated that the α-enolase of S. iniae was not only distributed in the cytoplasm and associated to cell walls, but was also secreted t...

Streptococcus iniae is an emerging zoonotic pathogen; such infections generally occur through injuries associated with preparing whole fresh fish for cooking. Those infected to date have been of Asian descent, are usually elderly (average age 68 years), and have had >/=1 underlying conditions that may predispose them to infection. Studies of the foundations of growth characteristics of S. iniae...

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...

in this study, immune responses against streptococcus iniae infections in rainbow trout (oncorhynchus mykiss) were analyzed. anti-streptococcal antibody (asa) levels, respiratory burst activity (rba), phagocytic activity (pa) and phagocytic index (p index) were measured in kidney macrophages. fish were allocated to three experimental groups (n = 50 per group): survivors of natural s. iniae inf...

streptococcus iniae is one of the most important agents that causes high mortality and losses in rainbow trout farms in iran and the world. these bacteria can affects the consumers and people who deal with aquaculture via affected fish. so, viability of this bacterium in frozen fish and fish product can be useful for health care of consumers. a total of 90 rainbow trout, with average weight of ...

Streptococcus iniae is among the major pathogens of a large number of fish species cultured in fresh and marine recirculating and net pen production systems. The traditional plate culture technique to detect and identify S. iniae is time consuming and may be problematic due to phenotypic variations of S. iniae isolates. The rapid transmission and severe economic impact of this disease necessita...

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 diagnosti...
