Streptococcus iniae was isolated from red-tail black shark(RTB shark) Epalzeorhynchos bicolor, and rainbow shark, E. erythrurus (fam: Cyprinidae), obtained from a local freshwater ornamental fish farm in Hillsborough county (FL). [...] Key Result Darkening of the skin and lethargy were the first signs observed in infected sharks. Hemorrhages were observed on the ventral side of the body, on the head, and at the base of the pelvic and pectoral fins.Expand

Pathomorphology of experimental Streptococcus iniae infection in tilapia (Oreochromis niloticus)
TLDR
An experimental infection with Streptococcus iniae was conducted with tilapia, and dense bacterial clusters were observed in the sinusoids of the spleen, while lymphocytes and macrophage infiltrations were found in the heart and intestinal tissues. Expand
Short Communication Experimental study to evaluate the pathogenicity of Streptococcus iniae in Guppy (Poecilia reticulata)
TLDR
P. reticulata is susceptible to streptococcosis and can play an important role in transmission of the disease to other ornamental fish species and also cultured fish. Expand
Streptococcosis in freshwater farmed seabass Lates calcarifer and its virulence in Nile tilapia Oreochromis niloticus
TLDR
This is the first report of S. iniae isolated from disease occurrences in freshwater-inland cultured seabass in Thailand, giving the possibility that the bacteria may be excreted into the rearing water via feces. Expand
Streptococcus iniae Isolated from Channel Catfish (Ictalurus punctatus) in China
TLDR
A new infectious disease was characterized in channel catfish (Ictalurus punctatus) in Guangxi Province, China, and Koch’s postulate was fulfilled using the authors' strain (labeled DGX07) in healthy channel cat fish. Expand
First report of Streptococcus iniae in red porgy (Pagrus pagrus, L.).
This work describes the first isolation of Streptococcus iniae in red porgy, Pagrus pagrus (L.), and the first European isolation of this pathogen in gilthead seabream, Sparus aurata (L.). In bothExpand
First identification and characterization of Streptococcus iniae obtained from tilapia (Oreochromis aureus) farmed in Mexico.
TLDR
The obtained data clearly indicate a relationship between intensified aquaculture activities in Mexico and new disease appearances, and should establish clinical significances for the tilapia industry. Expand
Outbreaks of Streptococcosis associated with Streptococcus iniae in Siberian sturgeon (Acipenser baerii) in China
TLDR
Results indicated that S. iniae could act as a pathogen of farmed A. baerii, the first report of S. iniae infection associated with mass mortality in A. Baerii. Expand
Isolation and characterization of the Enterococcus faecalis strain isolated from red tilapia (Oreochromis hybrid) in Indonesia: A preliminary report
TLDR
It is concluded that E. faecalis were found as the cause of streptococcosis, infecting and causing mild lesions in red tilapia and this finding is the first report of isolation and characterisation of the E. Faecalis strain isolated from red Tilapia in Indonesia. Expand
Main bacterial species causing clinical disease in ornamental freshwater fish in Brazil.
TLDR
MALDI-TOF MS showed to be a rapid method for diagnosis of bacterial disease outbreaks in ornamental fish establishments and was shown to be the main causative bacterial agents of infection in Ornamental fish with different clinical signs. Expand
SURVEY ON VIABILITY OF STREPTOCOCCUS INIAE IN FROZEN RAINBOW TROUT (ONCORHYNCHUS MYKISS) FOLLOWING EXPERIMENTAL INFECTION
TLDR
According to this study, Streptococcus iniae as a zoonisis can be survived at least 38 month in freezing temperature (at -20˚C) in fish products, so the potential pathogenicity of this bacterium should be concerned in affected area as well as imported frozen fish. Expand

Streptococcus iniae infections in Red Sea cage-cultured and wild fishes.
TLDR
Biochemical and molecular similarities between the isolates from cultured fishes and those from the wild specimens suggest that a single strain is involved, and that 'amplification' and dispersal of this pathogen from captive to feral fishes have occurred. Expand
Streptococcus iniae Associated with Mortality of Tilapia nilotica × T. aurea Hybrids
TLDR
The cause of an ongoing mortality of hybrid tilapias Tilapia nilotica × T. aurea in a Texas fish farm was a biotype of Streptococcus iniae, the first record of this bacterial species affecting fish in the USA. Expand
Histopathology of Hybrid Tilapias Infected witha Biotype of Streptococcus iniae
TLDR
A systemic streptococcal disease caused by a biotype of Streptococcus iniae affecting hybrids of Nile tilapia Tilapia nilotica × bluetilapia T. aurea at a commercial aquaculture facility in central Texas was investigated, revealing a general septicemia with the occurrence of cellular infiltration and numerous cocci in most organ systems.

Studies on the pathogenesis of streptococcal infection in cultured yellowtails Seriola spp.: the fate of Streptococcus sp. bacteria after inoculation
TLDR
The growth of the bacteria in the fish body at various periods after either per-oral or per-cutaneous challenge with Streptococcus sp. Expand
Invasive infections due to a fish pathogen, Streptococcus iniae. S. iniae Study Group.
TLDR
A clone of S. iniae that causes invasive disease in both humans and fish is identified that can produce invasive infection after skin injuries during the handling of fresh fish grown by aquaculture. Expand
Pharmacokinetic Studies of Florfenicol in Koi Carp and Threespot Gourami Trichogaster trichopterus after Oral and Intramuscular Treatment
TLDR
Analysis of florfenicol leaching from fish feed indicated that about 50–80% of the coated drug is lost and is not available for therapeutic benefit for either species. Expand
Laboratory Efficacy of Amoxicillin for the Control of Streptococcus iniae Infection in Blue Tilapia
TLDR
Oral administration of AMX-medicated feed for 12 d at a daily rate of 10, 30, and 80 mg/kg BW significantly increased the survival of S. iniae−infected tilapia from 3.8% in the challenged, nonmedicated positive control to 45, 75, and 93.8%, respectively. Expand
Density and dose: factors affecting mortality of Streptococcus iniae infected tilapia /Oreochromis niloticus
TLDR
It is demonstrated density has a significant effect on streptococcal disease mortality in tilapia exposed to S. iniae by immersion, and a health-management strategy would be to reduce fish density thus lowering strept bacteria disease mortality. Expand
Studies on the pathogenesis of streptococcal infection in cultured yellowtails Seriola spp.: effect of the cell free culture on experimental streptococcal infection.
TLDR
Intramuscular inoculation with either low virulent or virulent bacteria alone at dosages of 106 to 107 cells did not produce the disease in the fish, with almost complete clearance of the bacteria from the viscera and blood within 120 h, when the exotoxin was inoculated intramUScularly prior to the bacterial challenge. Expand
Passive immunization of tilapia, Oreochromis niloticus (L.), with anti-Streptococcus iniae whole sera
TLDR
Results suggest that immunity provided by ASI and HIASI was because of antibody against S. iniae, and inactivation of complement in theHIASI treatment further suggests that ASI antibody plays a primary role in immunity against S iniae. Expand
