The indirect fluorescent antibody technique has been used successfully for the rapid serological identification of the Streptococcus sp. responsible for streptococcosis of rainbow trout. This technique has been used to identify the Streptococcus sp. in pure cultures and smears made from experimentally infected and diseased fish.

Streptococcus iniae 89353 is a virulent strain isolated from diseased tilapia in Taiwan. The full-genome sequence of S. iniae 89353 is 2,098,647 bp. The revealed genome information will be beneficial for identification and understanding of potential virulence genes of Streptococcus iniae and possible immunogens for vaccine development against streptococcosis.

Streptococcus iniae is associated with morbidity in commercial fish species, especially in olive flounders (Paralichthys olivaceus), and was recently identified as an emerging human pathogen. Here, we report the complete 2.09-Mb genome sequence of S. iniae strain YSFST01-82, isolated from an olive flounder with streptococcosis disease in Jeju, South Korea.

this study evaluated the effects of probiotic, lactobacillus plantarum on serum biochemical and some immune parameters of immunized rainbow trout weighting 29.6±1.84 g, with streptococcosis/lactococosis vaccine at 16±1.5°c, for 60 days. a commercial diet was used as the control. fish in the first treatment were immunized with streptococcosis/lactococosis vaccine in bathing route for 1 min. in t...

This paper describes the whole-genome sequences for three Streptococcus agalactiae serotype Ia isolates. The isolates were recovered from the brains of clinically sick tilapia, Oreochromis niloticus, that were suffering from streptococcosis. One isolate was from tilapia in the United States and the other two from fish in China.

Streptococcus iniae ISET0901 is a virulent strain isolated in 2007 from diseased tilapia. Its full genome is 2,070,856 bp. The availability of this genome will allow comparative genomics to identify virulence genes important for the pathogenesis of streptococcosis caused by S. iniae, as well as possible immunogens for vaccine development.

In the livestock farms of our country, infectious diseases are becoming more and common in their etiology, dominant role belongs to opportunistic microflora. Streptococcus also this group microorganisms [1].
 Streptococcosis is an disease young farm animals, characterized by severe septic phenomena, inflammation respiratory system, gastrointestinal tract, joints.

This study investigates the clinicopathological features of acute experimental streptococcosis in red tilapia using various routes of infection; intraperitoneal (IP), immersion (IM) and immersion cut (IC). Twenty four red tilapia in duplicates were inoculated intraperitoneally with 10(9) CFU/ml of S. agalactiae while another sets: intact, one with sharp cut at the tail end were exposed to bacte...

Aditoprim (ADP) has potential use as an antimicrobial agent in animals. However, its pharmacodynamic properties have not been systematically studied yet. In this study, the in vitro antibacterial activities of ADP and its main metabolites were assayed, and the in vivo antibacterial efficacy of ADP for the treatment of swine streptococcosis was evaluated. It was shown that Salmonella and Strepto...

In this study Bacillus subtilis is used for control of streptococcosis with the agent of Streptococcus iniae in Rainbow trout. The experience was carried out in 2 groups (Control and Treatment) and 3 replicates. In Control group, probiotic was not applied in diet but in Treatment group, Bacillus subtilis was administered in feed at a concentration of 10 cells g . In the day of forty five, 0.1 m...
