Complete Genome Sequence and Comparative Analysis of the Fish Pathogen Lactococcus garvieae
Lactococcus garvieae causes fatal haemorrhagic septicaemia in fish such as yellowtail. The comparative analysis of genomes of a virulent strain Lg2 and a non-virulent strain ATCC 49156 of L. garvieae revealed that the two strains shared a high degree of sequence identity, but Lg2 had a 16.5-kb capsule gene cluster that is absent in ATCC 49156. The capsule gene cluster was composed of 15 genes, ...
متن کاملThe protective immune response of yellowtail Seriola quinqueradiata to the bacterial fish pathogen Lactococcus garvieae.
Yellowtail Seriola quinqueradiata were immunized with 2 different Lactococcus garvieae bacterin, formalin-killed KG- phenotype cells (capsulated phenotype) and formalin-killed KG+ phenotype cells (unencapsulated phenotype). These 2 injected vaccines conferred long-term protection to yellowtail against an artificial infection of an encapsulated Lactococcus garvieae strain with long-lasting agglu...
متن کاملDevelopment of a sensitive and specific LAMP PCR assay for detection of fish pathogen Lactococcus garvieae.
Based on use of a loop-mediated isothermal amplification (LAMP) identification protocol, this study attempted to detect Lactococcus garvieae in fish by using primer sets designed from an L. garvieae alpha/beta fold family hydrolase gene. Reaction time and temperatures were optimized for 60 min at 60°C with the resulting amplicons visualized by adding SYBR Green I to the reaction tube. The assay...
متن کاملFirst report of human acute acalculous cholecystitis caused by the fish pathogen Lactococcus garvieae.
We report herein the first case of acute acalculous cholecystitis caused by Lactococcus garvieae, which is known as a fish pathogen. A 69-year-old fisherman underwent laparoscopic cholecystectomy due to severe inflammation in the gallbladder. The isolate obtained from the gallbladder was identified as L. garvieae by 16S rRNA and manganese-dependent superoxide dismutase (sodA) gene sequence anal...
متن کاملLactococcus garvieae, an emerging pathogen for the Portuguese trout culture
We report here the first description in North Portugal of epizootic episodes of lactococcosis causing important mortalities in cultured rainbow trout associated with high water temperatures. The outbreaks that occurred during the warm seasons of 2002 and 2003 affected all size fish, reaching up to 90% mortality in some farms. The taxonomic studies of the isolates obtained indicated that they be...
