“…Bacterial species identification was done using MALDI-TOF MS -matrix-assisted laser desorption ionisation-time of flight mass spectrometry (Microflex LT, Bruker Daltonics, Brehmen, Germany) (Oravcova et al, 2014b) and by sequencing of sodA gene as described previously (Frolkova et al, 2012). Enterococcus dispar was further confirmed by ribotyping with the EcoRI restriction enzyme using the RiboPrinter microbial characterisation system (DuPont Qualicon, USA) (Frolkova et al, 2013). The susceptibility to ampicillin (10 lg/disc), ciprofloxacin (5), chloramphenicol (30), erythromycin (15), gentamicin (120), linezolid (30), nitrofurantoin (300), quinupristin/dalfopristin (15), rifampicin (5), streptomycin (300), teicoplanin (30), tetracycline (30), tigecycline (15) and vancomycin (30) was determined by disc diffusion method.…”

This study is revealing the possible dissemination of vancomycin-resistant enterococci (VRE) from humans into the wildlife. We studied silver gulls (Chroicocephalus novaehollandiae) in Australia as potential carriers and reservoirs of VRE with acquired vancomycin resistance. In New South Wales (Australia), we have found two multi-resistant isolates belonging to Enterococcus faecium (sequence type 341, vanB genotype) and Enterococcus dispar (vanA genotype). Based on our knowledge, this is the first report of VRE in Australian wildlife.

“…On the other hand, L. acidophilus and L. animalis are species used as probiotics [56,57] and W. paramesenteroides has probiotic characteristics [58]. L. gasseri also has probiotic characteristics [59,60]. Based on the results of other studies, it can be inferred that the changes in intestinal microbiota might be because of E. faecium , which is commonly used as a probiotic.…”

Simple SummaryDog foods are becoming more equivalent to human foods, and functional additives are being included in their diets to promote health. In this study, turmeric, glasswort, and Ganghwa mugwort were used as medicinal plants and were subjected to fermentation by autochthonous Enterococcus faecium. Fermentation significantly improved the in vitro antioxidant activities of these plants. Food preference tests of dog foods containing these fermented medicinal plants were conducted in beagles.AbstractThis research determined the antioxidant activities of medicinal plants fermented by Enterococcus faecium and their subsequent applications as dog food additives. Turmeric (5%, w/v), glasswort (2.5%, w/v), Ganghwa mugwort (2.5%, w/v), and their mixture (5%, w/v) were fermented by autochthonous E. faecium (1%, v/v) for 72 h. Bacterial cell counts and pH were monitored during fermentation. Total polyphenol content (TPC), total flavonoid content (TFC), 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, and intracellular superoxide scavenging activity in bovine mammary alveolar epithelial (MAC-T) cells were measured with the fermented and non-fermented samples. Only the antioxidant capacity of the mixture was increased after fermentation. However, intracellular superoxide level in MAC-T cells was significantly reduced after treatment with fermented plant samples (p < 0.001) as compared with that in non-fermented plants. Fermented plants were then sprayed at 1% (v/w) onto dog foods. TPC, TFC, ABTS radical scavenging activity, and DPPH radical scavenging activity of dog foods were significantly enhanced after the addition of fermented plants. Food preference testing was conducted using a two-pan method—control diet vs. four treatment diets—for 4 days for each additive diet, a total 16 days in 9 beagles. Feces were collected to enumerate bacterial counts. Preferences for glasswort and Ganghwa mugwort were higher than those of the control (p < 0.05). Furthermore, fecal microbiota enumeration displayed a higher number of beneficial microorganisms in treated groups. These results suggest that fermented plants with enhanced antioxidant abilities might be useful as potential additives for dog foods.

“…Enterococci are Gram-positive, catalase-negative, facultatively anaerobic cocci, and are found in various food, plant and animal sources [1][2][3][4][5][6][7]. Strain ALS3 T was previously isolated from fresh coffee cherries collected on Ali Mountain (23° 28′ 04.8″ N 120° 42′ 48.4″ E) and was considered as a potential novel species or subspecies of lactic acid bacteria [8].…”

A coccus-shaped organism, designated ALS3T, was isolated from fresh coffee cherries collected at a farm located in the Ali Mountain region of Taiwan. Sequence analysis of its 16S rRNA gene indicated that strain ALS3T belongs to the genus Enterococcus and has more than 98.5 % sequence similarity to Enterococcus pallens and Enterococcus hermanniensis . When comparing the ALS3T genome with these two type strains, the average nucleotide identity values and digital DNA–DNA hybridization values were 72.6–73.3 and 19.2 %, respectively. The G+C content of the genomic DNA from strain ALS3T was 35.6 mol%. Results of sequence analysis, together with enzymatic activities and characteristics of carbohydrate metabolism, indicated that strain ALS3T is distinct and represents a novel species, for which the name Enterococcus alishanensis sp. nov. is proposed. The type strain is ALS3T (=NBRC 109593T=BCRC 80605T).
