Lactococcus garvieae in fish: A review

Comparative Immunology, Microbiology and Infectious Diseases, 2006
Lactococcus garvieae is the etiological agent of Lactococcosis, an emergent disease which affects many fish species and causes important economic losses both in marine and freshwater aquaculture when water temperature increases over 16 degrees C in summer months. Normally, it causes a hyperacute and haemorrhagic septicemia.

Genome plasticity in Lactococcus lactis

Antonie van Leeuwenhoek, 2002
Comparative genome analyses contribute significantly to our understanding of bacterial evolution and indicate that bacterial genomes are constantly evolving structures. The gene content and organisation of chromosomes of lactic acid bacteria probably result from a strong evolutionary pressure toward optimal growth of these microorganisms in milk.

Endocarditis Caused by Lactococcus cremoris

Scandinavian Journal of Infectious Diseases, 2002
We describe a case of subacute endocarditis due to Lactococcus cremoris associated with consumption of unpasteurized milk. Treatment with amoxicillin-clavulanic acid and subsequently penicillin resulted in prompt sterilization of this patient's bloodstream and full recovery.

Autolysis of Lactococcus lactis

International Dairy Journal, 2002
Abstract During cheese making, autolysis of Lactococcus lactis starter bacteria affects cheese flavour development through release of intracellular enzymes. The gene for the major autolysin in L. lactis, N-acetyl muramidase (AcmA), has been cloned and sequenced. The activity of AcmA alone, however, does not explain the huge variation in the extent of

16S–23S rDNA Intergenic Spacer Region Polymorphism of Lactococcus garvieae, Lactococcus raffinolactis and Lactococcus lactis as Revealed by PCR and Nucleotide Sequence Analysis

Systematic and Applied Microbiology, 2002
The intergenic spacer region (ISR) between the 16S and 23S rRNA genes was tested as a tool for differentiating lactococci commonly isolated in a dairy environment. 17 reference strains, representing 11 different species belonging to the genera Lactococcus, Streptococcus, Lactobacillus, Enterococcus and Leuconostoc, and 127 wild streptococcal strains ...

The genus Lactococcus

1995
Lactococci are coccoid Gram-positive, anaerobic bacteria which produce l(+)-lactic acid from lactose in spontaneously fermented raw milk which is left at ambient temperatures around 20–30°C for 10–20 h. They are commonly called ‘mesophilic lactic streptococci’.

Electrotransformation of Lactococcus lactis

2000
The last decade has seen a spectacular increase in genetic technology of Lactococcus lactis, the model lactic acid bacterium extensively used as starter culture in the manufacture of dairy products. The development of transformation techniques (Gasson & Fitzgerald 1994) and construction of powerful plasmids for gene cloning (de Vos & Simons 1994), as ...

Regulation of carbon catabolism in Lactococcus lactis

2000
The Lactococcus lactis IL1403 is a lactose negative, plasmid free strain. Nevertheless, it is able to hydrolyze lactose in the presence of cellobiose.In this work we describe identification of a gene involved in this process. The gene was found to be homologous to the sugar catabolism regulator, ccpA.

[Lactococcus garvieae endocarditis].

Nederlands tijdschrift voor geneeskunde, 2015
Lactococcus garvieae, a Gram-positive lactococcus with a short incubation period and high virulence, is a known fish pathogen responsible for serious outbreaks in both marine and freshwater aquaculture. The first human infection was documented in 1991. This is the first case report of L.
