“…They are frequently isolated from plant material, e.g. fresh vegetables, cassava and silage (Wang and Nishinno 2008), cacao beans (De Bruyne et al 2008), as well as from meat and meat products (Milbourne 1983;Collins et al 1993;Han et al 2010;Patterson et al 2010;Han et al 2011;Comi and Iacumin 2012;Doulgeraki et al 2012;Kesmen et al 2012), fish (Tanasupawat et al 2000;Liu et al 2009), kimchi (Choi et al 2002;Jang et al 2002;Lee et al 2002), specialties from Malaysia (Björkroth et al 2002), soil (Magnusson et al 2002) and, in isolated cases, they can also occur in clinical material of human or animal origin. In such cases, they are of course associated with other bacteria.…”

Although ubiquitous, bacteria of the Weissella genus are not given sufficient attention. Many members of the genus were originally classified as Leuconostoc or Lactobacillus. With the development of molecular methods, these phylogenetically closely related bacteria formed a separate group, the Weissella genus. Due to its heterofermentative metabolism, Weissella spp. may cause considerable damage particularly in the meat industry. Slime formation and greening of meat products are sensory defects for which the technologically important species Weissella viridescens is responsible. This article summarizes basic information about the influence of Weissella viridescens on meat processing.

“…This W. halotolerans protein could be an ElrA-like protein as it shares 34% of identity with ElrA and contains in addition to the FID, an LRR repeat domain and a WxL domain. It is noteworthy that W. halotolerans is an opportunistic pathogen for the rainbow trout 58 .…”

The commensal bacterium Enterococcus faecalis is a common cause of nosocomial infections worldwide. The increasing prevalence of multi-antibiotic resistant E. faecalis strains reinforces this public health concern. Despite numerous studies highlighting several pathology-related genetic traits, the molecular mechanisms of E. faecalis virulence remain poorly understood. In this work, we studied 23 bacterial proteins that could be considered as virulence factors or involved in the Enterococcus interaction with the host. We systematically tested their interactions with human proteins using the Human ORFeome library, a set of 12,212 human ORFs, in yeast. Among the thousands of tested interactions, one involving the E. faecalis virulence factor ElrA and the human protein FHL2 was evidenced by yeast two-hybrid and biochemically confirmed. Further molecular characterizations allowed defining an FHL2-interacting domain (FID) of ElrA. Deletion of the FID led to an attenuated in vivo phenotype of the mutated strain clearly indicating that this interaction is likely to contribute to the multifactorial virulence of this opportunistic pathogen. Altogether, our results show that FHL2 is the first host cellular protein directly targeted by an E. faecalis virulence factor and that this interaction is involved in Enterococcus pathogenicity.

“…Weissella ceti is a Gram-positive bacterium that is the etiologic agent of weissellosis in farm-raised rainbow trout, Oncorhynchus mykiss (Walbaum, 1792) (1, 2). This emergent disease occurs mainly during summer season, and it is characterized by acute hemorrhagic septicemia and high mortality (3).…”

“…This emergent disease occurs mainly during summer season, and it is characterized by acute hemorrhagic septicemia and high mortality (3). Outbreaks caused by W. ceti have been reported from farms in China, Brazil, and the United States (1–4). In 2013, the first genome sequence of W. ceti isolated from rainbow trout was published (5), which was deposited as a draft genome containing eight unordered contigs.…”
