TLDR
Strains exhibiting virulence traits were not necessarily positive for all traits; thus, the incidence of virulence factors may be considered to be strain specific.Abstract:
The incidence of virulence factors among 48 Enterococcus faecium and 47 Enterococcus faecalis strains from foods and their antibiotic susceptibility were investigated. No strain was resistant to all antibiotics, and for some strains, multiple resistances were observed. Of E. faecium strains, 10.4% were positive for one or more virulence determinants, compared to 78.7% of E. faecalis strains. Strains exhibiting virulence traits were not necessarily positive for all traits; thus, the incidence of virulence factors may be considered to be strain specific.read more

The role and application of enterococci in food and health.
TL;DR: The aim of the present review is to give a balanced overview of both beneficial and virulence features of this divisive group of microorganisms, because it is only acquaintance with both sides that may allow their safe exploitation as starter cultures or co-cultures.

Antibiotic resistance in food lactic acid bacteria--a review.
Shalini Mathur,Rameshwar Singh +1 more
TL;DR: A number of initiatives have been recently launched by various organizations across the globe to address the biosafety concerns of starter cultures and probiotic microorganisms to lead to better understanding of the role played by the dairy starter microorganisms in horizontal transfer of antibiotic resistance genes to intestinal microorganisms and food-associated pathogenic bacteria.
Journal ArticleDOI
Functionality of enterococci in dairy products.
TL;DR: There is evidence that enterococci, either added as adjunct starters or present as nonstarter NSLAB, could find potential application in the processing of some fermented dairy products.
Journal ArticleDOI
Enterococci from foods
TL;DR: Enterococci are low grade pathogens but their intrinsic resistance to many antibiotics and their acquisition of resistance to the few antibiotics available for treatment in clinical therapy have led to difficulties and a search for new drugs and therapeutic options.
Journal ArticleDOI
Enterococci as probiotics and their implications in food safety
TL;DR: The use of enterococcal probiotics should, in view of the development of problematic lineages and the potential for gene transfer in the gastrointestinal tract of both humans and animals, be carefully monitored, and the advantages of using these and new strains should be considered in a well contemplated risk/benefit analysis.

Rapid extraction of bacterial genomic DNA with guanidium thiocyanate
TL;DR: The method, which was applicable to both Gram‐positive and Gram‐negative bacteria, eliminated endogenous nuclease activity and avoided the need for phenol, RNase and protease treatments.
Journal ArticleDOI
The life and times of the Enterococcus.
TL;DR: Enterococci are important human pathogens that are increasingly resistant to antimicrobial agents, including resistance to cephalosporins, clindamycin, tetracycline, and penicillinase-resistant penicillins such as oxacillin, among others.

Virulence of enterococci.
TL;DR: The current understanding of enterococcal virulence relating to adherence to host tissues, invasion and abscess formation, factors potentially relevant to modulation of host inflammatory responses, and potentially toxic secreted products are discussed.
