“…Members of the genus have been isolated largely from food-related sources and are generally regarded as safe (GRAS) organisms (Salminen et al, 1998). However, rare cases of invasive disease in humans, sometimes severe, have been reported in association with L. garvieae (Vinh et al, 2006;Wang et al, 2007; Yiu et al, 2007) and L. lactis (Mannion & Rothburn, 1990) infections. The case study by Wang et al (2007) raised awareness of a potential risk factor for gastrointestinal disease from L. garvieae linked to the consumption of raw seafood (squid) in the summer months, although their 16S rRNA gene sequence analysis may not have been the best method of establishing an epidemiological link.…”

The taxonomic position of a Gram-positive coccus, designated strain CAU 28 T , isolated from activated sludge foam was determined by using a polyphasic approach. Based on its cellular morphology and the results of biochemical tests, strain CAU 28 T was identified tentatively as a member of the genus Lactococcus. Comparative 16S rRNA gene sequence analysis showed that levels of similarity between strain CAU 28 T and the type strains of recognized Lactococcus species ranged from 90.4 to 97.2 %. DNA-DNA hybridization studies showed that strain CAU 28 T displayed less than 26.1 % relatedness to the type strains of recognized Lactococcus species. The rep-PCR fingerprints revealed that strain CAU 28 T was well separated from reference Lactococcus species. The combined genotypic and phenotypic data indicate that strain CAU 28 T represents a novel species of the genus Lactococcus, for which the name Lactococcus chungangensis sp. nov. is proposed. The type strain is CAU 28 T (5KCTC 13185 T 5CCUG 55099 T ).Lactococcus Schleifer et al. 1986 was first established as a separate genus distinct from the genus Streptococcus by Schleifer et al. (1985). At the time of writing, Lactococcus comprises five recognized species (Euzéby, 1997; Schleifer et al. 1986. Members of the genus Lactococcus have been identified as lactic acid bacteria that contribute significantly to the properties of fermented dairy products while others produce antimicrobial compounds. Members of the genus have been isolated largely from food-related sources and are generally regarded as safe (GRAS) organisms (Salminen et al., 1998). However, rare cases of invasive disease in humans, sometimes severe, have been reported in association with L. garvieae (Vinh et al., 2006;Wang et al., 2007; Yiu et al., 2007) and L. lactis (Mannion & Rothburn, 1990) infections. The case study by Wang et al. (2007) raised awareness of a potential risk factor for gastrointestinal disease from L. garvieae linked to the consumption of raw seafood (squid) in the summer months, although their 16S rRNA gene sequence analysis may not have been the best method of establishing an epidemiological link. The exact source of infection in squid and the farm of its origin could not be identified, and a much larger study is needed to confirm risk factors for potential gastrointestinal infection with L. garvieae. Several reports show that L. garvieae is an important pathogen of fish, squid and prawns, causing economic losses both in marine and in freshwater aquaculture (Carson et al., 1993;Chen et al., 2001Chen et al., , 2002Pereira et al., 2004; Vendrell et al., 2006). In addition, L. garvieae has been isolated from cases of bovine mastitis (Collins et al., 1983;Teixeira et al., 1996). Until now, however, there have been no reports ofThe GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain CAU 28 T is EF694028. for 3 days at 37 u C.

“…garvieae has been isolated from various hosts, including rainbow trout, bovine and humans (Carson et al, 1993;Teixeira et al, 1996;Vinh et al, 2006). Unfortunately, the PCR assay reported here was ineffective in discriminating between serotype I strains and strains isolated from other sources.…”

“…5 The genus Lactococcus contains eight species and subspecies, of which the most common species involved in human infections are Lactococcus lactis and L. garvieae. 6 Since an increasing number of human infections due to L. garvieae have been reported in recent times, this organism has gained recognition as an emerging zoonotic pathogen.…”

“…6 Since an increasing number of human infections due to L. garvieae have been reported in recent times, this organism has gained recognition as an emerging zoonotic pathogen. [2][3][4][5][6] One probable reason for its increasing reports might be availability of advanced bacterial identification techniques. A total of 21 cases of L. garvieae with clinical details have been reported in the literature 7 ; most of which were suffering from endocarditis.…”
