In the present study a novel species of the genus Weissella, which is associated with wine grape berries is described.…”

Two bacterial strains (B18BM42 T and B18NM6) were recovered during a study of bacterial diversity on wine grapes (Vitis vinifera L.) from the Nemea region in Greece. Phylogenetic analysis based on 16S rRNA gene sequences placed the two strains within the genus Weissella, and found them to be most closely related to Weissella minor NRIC 1625 T followed by Weissella viridescens NRIC 1536 T (99.1 and 98.9 % sequence similarity, respectively). The level of DNA-DNA relatedness between strains B18NM42 T and W. minor NRIC 1625 T or W. viridescens NRIC 1536 T was 31.9 and 35.0 %, respectively. The two novel strains could be genetically differentiated from their closest relatives by REA-PFGE (restriction enzyme analysis-pulse field gel electrophoresis), RAPD (randomly amplified polymorphic DNA) and rep-PC R analyses (repetitive sequence-based PCR). Physiological examination showed that the novel strains can be distinguished from phylogenetically related species by their ability to grow at 42 6C and by certain carbohydrate fermentations. Based on the evidence above, the affiliation of the two strains to a novel species with the proposed name Weissella uvarum sp. nov. is suggested. The type strain is B18NM42 T (5DSM 28060 T 5NCCB 100484 T ).

Bacteria assigned to the genus Weissella are Gram-positive, catalase-negative, non-endospore forming cells with coccoid or rod-shaped morphology (Collins et al., 1993; Björkroth et al., 2009, 2014) and belong to the group of bacteria generally known as lactic acid bacteria. Phylogenetically, the Weissella belong to the Firmicutes, class Bacilli, order Lactobacillales and family Leuconostocaceae (Collins et al., 1993). They are obligately heterofermentative, producing CO2 from carbohydrate metabolism with either d(−)-, or a mixture of d(−)- and l(+)- lactic acid and acetic acid as major end products from sugar metabolism. To date, there are 19 validly described Weissella species known. Weissella spp. have been isolated from and occur in a wide range of habitats, e.g., on the skin and in the milk and feces of animals, from saliva, breast milk, feces and vagina of humans, from plants and vegetables, as well as from a variety of fermented foods such as European sourdoughs and Asian and African traditional fermented foods. Thus, apart from a perceived technical role of certain Weissella species involved in such traditional fermentations, specific Weissella strains are also receiving attention as potential probiotics, and strain development of particularly W. cibaria strains is receiving attention because of their high probiotic potential for controlling periodontal disease. Moreover, W. confusa and W. cibaria strains are known to produce copius amounts of novel, non-digestible oligosaccharides and extracellular polysaccharides, mainly dextran. These polymers are receiving increased attention for their potential application as prebiotics and for a wide range of industrial applications, predominantly for bakeries and for the production of cereal-based fermented functional beverages. On the detrimental side, strains of certain Weissella species, e.g., of W. viridescens, W. cibaria and W. confusa, are known as opportunistic pathogens involved in human infections while strains of W. ceti have been recently recongnized as etiological agent of “weissellosis,” which is a disease affecting farmed rainbow trouts. Bacteria belonging to this species thus are important both from a technological, as well as from a medical point of view, and both aspects should be taken into account in any envisaged biotechnological applications.

“…The genus Weissella was established in 1993 and to date, 19 names have been attributed to 18 species ( W. cibaria is considered a synonym of W. kimchii ) [ 3 ]. The majority of Weissella strains have been isolated from vegetables, fermentative substrates, meat, meat products, and the gastrointestinal tracts of some animal species, insects, and humans [ 4 – 6 ]. Several species, including W. confusa and W. cibaria , have been associated with rare cases of bacteremia in humans and animals [ 7 – 10 ].…”

Comparative genome analysis of Weissella ceti, an emerging pathogen of farm-raised rainbow trout

et al. 2015

BackgroundThe genus Weissella belongs to the lactic acid bacteria and includes 18 currently identified species, predominantly isolated from fermented food but rarely from cases of bacteremia in animals. Recently, a new species, designated Weissella ceti, has been correlated with hemorrhagic illness in farm-raised rainbow trout in China, Brazil, and the USA, with high transmission and mortality rates during outbreaks. Although W. ceti is an important emerging veterinary pathogen, little is known about its genomic features or virulence mechanisms. To better understand these and to characterize the species, we have previously sequenced the genomes of W. ceti strains WS08, WS74, and WS105, isolated from different rainbow trout farms in Brazil and displaying different pulsed-field gel electrophoresis patterns. Here, we present a comparative analysis of the three previously sequenced genomes of W. ceti strains from Brazil along with W. ceti NC36 from the USA and those of other Weissella species.ResultsPhylogenomic and orthology-based analyses both showed a high-similarity in the genetic structure of these W. ceti strains. This structure is corroborated by the highly syntenic order of their genes and the neutral evolution inferred from Tajima’s D. A whole-genome multilocus sequence typing analysis distinguished strains WS08 and NC36 from strains WS74 and WS105. We predicted 10 putative genomic islands (GEI), among which PAIs 3a and 3b are phage sequences that occur only in WS105 and WS74, respectively, whereas PAI 1 is species specific.ConclusionsWe identified several genes putatively involved in the basic processes of bacterial physiology and pathogenesis, including survival in aquatic environment, adherence in the host, spread inside the host, resistance to immune-system-mediated stresses, and antibiotic resistance. These data provide new insights in the molecular epidemiology and host adaptation for this emerging pathogen in aquaculture.Electronic supplementary materialThe online version of this article (doi:10.1186/s12864-015-2324-4) contains supplementary material, which is available to authorized users.
