Lactococcus garvieae , an emerging pathogen for the Portuguese trout culture

  title={Lactococcus garvieae , an emerging pathogen for the Portuguese trout culture},
  author={Fernando Pereira and Carmen Ravelo and Alicia E. Toranzo and Jes{\'u}s L Romalde},
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 belonged to Lactococcus garvieae. This identification was confirmed by PCR amplification using specific… CONTINUE READING
