Streptococcus infantarius subsp. infantarius (Sii) belongs to the Streptococcus bovis/Streptococcus equinus complex associated with several human and animal infections. Sii is a predominant bacterium in spontaneously fermented milk products in Africa. The genome sequence of Sii strain CJ18 was compared with that of other Streptococcus species to identify(More)
Bifidobacterium thermophilum RBL67, an isolate from infant feces, exhibits bacteriocin-like antimicrobial activity against Listeria spp. and Salmonella spp. and protects HT29-MTX cells against Salmonella infection. Here, the complete genome sequence of the probiotic B. thermophilum strain RBL67 is presented.
The complete genome sequence of Bifidobacterium kashiwanohense strain PV20-2, an infant feces isolate, was determined using single-molecule real-time sequencing (SMRT). Hierarchical genome assembly resulted in a completely assembled genome of 2,370,978 bp. The B. kashiwanohense PV20-2 genome is the first completely sequenced and assembled genome of the(More)
The Streptococcus bovis/Streptococcus equinus complex (SBSEC) comprises seven (sub)species classified as human and animal commensals, emerging opportunistic pathogens and food fermentative organisms. Changing taxonomy, shared habitats, natural competence and evidence for horizontal gene transfer pose difficulties for determining their phylogeny,(More)
The complete genome sequence of Bifidobacterium pseudolongum PV8-2, isolated from feces of an anemic Kenyan infant, was determined using single-molecule real-time (SMRT) technology. The genome consists of a 2-Mbp chromosome and a 4-kb plasmid.
Modulating the gut microbiota via dietary interventions is a common strategy to enhance the natural defence mechanisms of the host. Several in vitro studies have highlighted the probiotic potential of Bifidobacterium thermophilum RBL67 (RBL67) selected for its anti-Salmonella effects. The present study aimed to investigate the impact of RBL67 alone and(More)
Bacterial adhesion to epithelial surfaces affects retention time in the human gastro-intestinal tract and therefore significantly contributes to interactions between bacteria and their hosts. Bacterial adhesion among other factors is strongly influenced by physico-chemical factors. The accurate quantification of these physico-chemical factors in adhesion is(More)
