Lactococcus garvieae and Streptococcus iniae infections in rainbow trout Oncorhynchus mykiss: similar, but different diseases.
Clinical and macroscopic findings (anorexia, lethargy, loss of orientation and exophthalmia) indicate that Streptococcus iniae and Lactococcus garvieae infections of trout share some common features, but histopathology reveals notable differences between the 2 diseases. Meningitis and panophthalmitis are the main lesions among S. iniae infected trout, whereas L. garvieae infection results in a ...
متن کاملEpidemiology, genotypic diversity, and antimicrobial resistance of Lactococcus garvieae in farmed rainbow trout (Oncorhynchus mykiss)
Bacterial agents must be genotypically analyzed for vaccinations, effective control programs, and antimicrobial resistance genes that could transfer from aquaculture settings to terrestrial ecosystems and humans. Therefore, we investigated the prevalence, genotypic characterization, and antimicrobial resistance of Lactococcus garvieae for two years at aquaculture sites throughout Turkey. A tota...
متن کاملSerum antibody response of rainbow trout, Oncorhynchus mykiss to two species of pathogenic bacteria; Streptococcus iniae and Lactococcus garviae
One of the most important bacterial diseases in aquaculture is Streptococosis/loctococosis. Meanwhile this disease has been known as a zoonosis disease, and then fish vaccination against this disease is important. In this study the specific immunological responses of rainbow trout (Oncorhynchus mykiss) to vaccination with bivalent lactococcal/streptococcal vaccine were investigated. Two hundred...
متن کاملSurvey on viability of Streptococcus iniae in frozen rainbow trout (Oncorhynchus mykiss) following experimental infection
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 ...
متن کاملResearch Article: Biotyping and serotyping of Lactococcus garvieae isolates in affected farmed rainbow trout (Oncorhynchus mykiss) in north Iran
The incidence of Lactococcosis caused by Lactococcus garvieae, in rainbow trout (Oncorhynchus mykiss, Walbaum, 1792) farms is disquieting and increasing in recent years. Knowledge of biotypes and serotypes involved in disease incidence is essential to adopt disease prevention and control policies. Twelve isolates of L. garvieae from some rainbow trout farms were identified by phenotypic, bioche...
