We report the complete genome sequence of Lactococcus lactis subsp. cremoris A76, a dairy strain isolated from a cheese production outfit. Genome analysis detected two contiguous islands fitting to the L. lactis subsp. lactis rather than to the L. lactis subsp. cremoris lineage. This indicates the existence of genetic exchange between the diverse subspecies, presumably related to the technologi...

OBJECTIVE Utilizing a food allergy murine model, we have investigated the intrinsic antiallergic potential of the Lactococcus lactis NCC 2287 strain. METHODS BALB/c mice were sensitized at weekly intervals with ovalbumin (OVA) plus cholera toxin (CT) by the oral route for 7 weeks. In this model, an oral challenge with a high dose of OVA at the end of the sensitization period leads to clinical...

Lactococcus lactis subsp. cremoris HP(T) has been widely used in studies of the metabolism of lactococcal dairy starter cultures. A comparison of the draft HP(T) genome with those from other strains of L. lactis subsp. cremoris will aid our understanding of the domestication and evolution of these important industrial cultures.

Lactococcus lactis subsp. cremoris A17, isolated from Taiwan fermented cabbage, is the first sequenced strain of L. lactis subsp. cremoris with immunomodulatory activity and antiallergic functions. The resulting A17 draft genome contains 2,679,936 bp and indicates that A17 is a potential exopolysaccharide-producing strain without any known virulence gene.

Lactococcus lactis is widely used in the dairy industry. We report the draft genome sequence of L. lactis subsp. lactis bv. diacetylactis LD61, an industrial and extensively studied strain. In contrast to the closely related and plasmidless strain IL1403, LD61 contains 6 plasmids, and the genome sequence provides additional information related to adaptation to the dairy environment.

Lactococcus garvieae junior synonym Enterococcus seriolicida) is an emerging zoonotic agent isolated from economically important fish (rainbow trout and yellowtail), from cattle, and from humans. Clindamycin susceptibility is the only phenotypic test which can differentiate L. garvieae from Lactococcus lactis, another emerging agent in humans. A PCR assay for the identification of L. garvieae w...

Lactococcin, a bacteriocin produced by Lactococcus lactis subsp. lactis ADRIA 85LO30, was purified as a 2.3-2.4 kDa peptide. Six non-bacteriocin-producing (Bac-) and non-immune (Imm-) strains were isolated after curing experiments. These strains had in common the loss or modification of two plasmids: pOS4 (32 kb) and pOS5 (70 kb). By comparing pOS5 and several modified plasmids, a DNA region fr...
