Endocarditis Caused by Lactococcus cremoris
Scandinavian Journal of Infectious Diseases, 2002We 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, 2002Abstract 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

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’.

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 ...

Electrotransformation of Lactococcus lactis
2000The 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 ...

PFGE Protocols to Distinguish Subspecies of Lactococcus lactis
2015Pulsed-field gel electrophoresis (PFGE), developed in the mid-1980s, rapidly became a "gold standard" method for analyzing bacterial chromosomes. Today, although outcompeted in resolution by alternative methods, such as optical mapping, and not applicable for high-throughput analyses, PFGE remains a valuable method for bacterial strain typing. Here, we

Abstract Lactococci are Gram-positive mesophilic bacteria with low G-C content that belong to the group of lactic acid bacteria. They are aerotolerant and live by means of fermentation, as they are lacking a respiratory chain, and the main end product during fermentation is lactic acid.

[Lactococcus garvieae endocarditis].
Nederlands tijdschrift voor geneeskunde, 2015Lactococcus 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.
