Epidemiology, 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 کاملLactococcus 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 کاملAn experimental study to evaluate pathogenicity of Yersinia ruckeri isolated from rainbow trout (Oncorhynchus mykiss) in Caspian trout (Salmo caspius)
The main objective of this study was to evaluate the pathogenicity of isolated Yersinia ruckeri from Caspian trout. Y. ruckeri specimens were isolated from infected rainbow trout farms located in north of Iran. The identification was confirmed by biochemical tests and 16s rRNA gene sequencing. The pathogenicity test was carried out to determine the virulence of the Y. ruckeri by IP injection...

Background: Lactococcus garvieae causes lactococcosis in rainbow trout in many parts of the world. Aims: This study was conducted for the existence of the virulent factors and differentiation of the two serotypes in L. garvieae. Methods: Twenty-two strains of L. garvieae isolated from diseased rainbow trout from farms...
