BACKGROUND Weissellicin L, a novel bacteriocin produced by Weissella hellenica 4-7, was previously characterized but its full amino acid sequence remain unknown. The draft genome sequencing analysis of Weissella hellenica 4-7 was performed and the open reading frame (ORF) encoding the weissellicin L was identified and clarified. FINDINGS The obtained results indicated that the mature bacterio...

The authors describe the first case of Weissella confusa infection of a prosthetic joint. Identification of the pathogen required 16S ribosomal RNA sequencing of isolates obtained on two separate occasions during the assessment of an elderly woman with a painful, swollen knee following total knee arthroplasty. A review of reported human infections due to W confusa are summarized, and risk facto...

We describe here the genome sequencing and annotation of Weissella ceti strains WS74 and WS105, isolated from diseased rainbow trout in Brazil. The two genomes were sequenced with an Ion Torrent personal genome machine (PGM) using a fragment library. The genomes of strains WS74 and WS105 consist of circular chromosomes 1,389,513 bp and 1,390,396 bp long, respectively, both presenting a G+C cont...

BACKGROUND The addition of sub therapeutic doses of antibiotics to cattle feed for growth promotion is a contributory factor to antibiotic resistance, thus an alternative to antibiotics is needed in animal feed additives. OBJECTIVE To determine the antimicrobial activity of cow's intestinal Lactic acid bacteria (LAB) against enteric commensals. METHOD Escherichia coli, Klebsiella species (s...

The influence of medium ingredients on extracellular dextransucrase production by a new bacterial strain Weissella confusa Cab3 (Genbank Accession Number JX649223) was evaluated using fractional factorial design of Taguchi’s orthogonal array. Four metabolism influencing factors viz. sucrose, yeast extract, K2HPO4 and Tween80 were selected to optimize dextransucrase production by W. confusa Cab3...
