Alterations of the gut flora from surgery or chemotherapy are believed to facilitate translocation of Weissella spp. data and propose formal denominations for isolates of these two species of Enterococcus. Weissella thalandienis was isolated from fermented fish, similar to Weissella salipisicis, a species that has not yet been validated by publication, and it is characterized by a cinnamyl esterase activity that also was found in W. confusa and W. viridescens. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png, http://www.deepdyve.com/lp/wiley/weissella-confusa-an-unexpected-cause-of-vancomycin-resistant-gram-o62JAe8BvY. Weissella spp. This is the first report describing the role of garlic as carbohydrate source for LAB in fermented fish products. Some W. confusa and Weissella cibaria strains isolated from fermented foods show favorable probiotic effects. Subcultures on sheep blood agar grew small, Gram-positive cocci. 15,000 peer-reviewed journals. It is usually, all classes of antibiotics with the exception of, and the antibiotics of choice include penicillin, clindam, cin, erythromycin, aminoglycosides and imipenem (Shin, daptomycin, which can be used as an effective alternative, for treatment of resistant isolates (Salimnia, This is the second case report of bacteraemia due to, may be a risk factor for bacteraemia due to this probiotic. A polymicrobial culture of W. confusa and Aeromonas hydrophila was identified from blood, for which treatment with meropenem and metronidazole was initiated. software. On the basis of biochemical identification and 16S rDNA sequencing, the W. confusa strain was identified as BSP201703. Bacteremia with S. moorei seems to be associated with debilitating conditions, but the prognosis of the infection appears to be good. A selective medium consisting of colistin-nalidixic acid agar, 5% sheep blood, vancomycin (5 mg/liter), and amphotericin B (8 mg/liter) was developed to isolate VRGPC. A thermotolerance test done in de Man, Rogosa and, susceptibility testing was performed using the Kir, blood as recommended by Clinical and Laboratory, Standards Institute guidelines (CLSI, 2006). Treeing analysis showed that the unknown bacterium formed a deep line branching at the periphery of rRNA cluster III and represents a hitherto unknown genus within this supra-generic grouping. Several new genera and species of gram-positive, catalase-negative cocci that can cause infections in humans have been described. It also possesses an in vitro antioxidant capacity, a high auto-aggregation ability, and a high surface hydrophobicity. © 2014 Springer Science+Business Media Dordrecht. Besides, Weissella spp. In total, 9% of the strains fermented starch and 19% fermented garlic, the two main carbohydrate components in som-fak. to be highly related at the species level to another blood isolate (SS 1743; CCUG 47884) from Sweden, and for these we propose paracasei, or garlic fermenting Lb. The typical culprit microorganisms are targeted empirically with ceftriaxone and vancomycin, in the absence of an immunocompromised state. MICs of these isolates for ten antimicrobial agents were determined by the agar dilution method. The organism was catalase-negative and grew under strictly anaerobic conditions and in the presence of 2 and 6 % O(2). L'identification des molécules produites et des enzymes impliquées est nécessaire afin de comprendre les mécanismes mis en jeu. Shin, J. H., Kim, D. I., Kim, H. R., Kim, D. S., Kook, J. K. & Lee, J. N. Walter, J., Hertel, C., Tannock, G. W., Lis, C. M., Munro, K. & Hammes. discover and read the research Possible safety concerns could come from Streptococcus lutetientis, isolated from the artificially altered tofu, Clostridium spp. Other Weissella strains showed resistance to low pH and bile salts and were isolated from healthy human feces, suggesting their potential as probiotics. Access scientific knowledge from anywhere. Clinical details of the pati, were not mentioned so their significance remains uncer-, bacteraemia in which the organism was misidentified as, rather than a skin contaminant since they are not, has been isolated from a variety of foodstuffs such as, meat, acid-rich carbohydrate food, garlic mix and, banana leaves (Kandler & Weiss, 1984; Paludan-Mu, human faeces and strains are considered normal micro-, particular study, four faecal isolates of, recovered from 48 stool samples from children with, bacteraemia who were screened for vancomycin-resistant, association of total parenteral nutrition and, species bacteraemia has been reported (Husni, 1997). Weissella confusa strain 6184 16S ribosomal RNA gene, partial sequence, Weissella confusa strain 6183 16S ribosomal RNA gene, partial sequence, Identification and Significance of Weissella species infections, A case report of polymicrobial bacteremia with Weissella confusa and comparison of previous treatment for successful recovery with a review of the literature, Meningitis due to Weissella Confusa: A case report and review, Recherche de bactéries lactiques autochtones capables de mener la fermentation de fruits tropicaux avec une augmentation de l'activité antioxydante, Isolation and Preliminary Screening of a Weissella confusa Strain from Giant Panda (Ailuropoda melanoleuca). Painter, P.H. Edited by P. H. A. Sneath, N. S. Mair, M. E. Sharpe &. Weissella confusa: A rare cause of vancomycinresistant Gram-positive bacteraemia . Fresh tofu is a traditional Asian soybean-derived food product which has become increasingly popular worldwide, however, little is known on its microbial ecology and the microbial groups that can cause its deterioration. (1989). Weissella confusa : an unexpected cause of vancomycin‐resistant gram‐positive bacteremia in... Salimnia, H.; Alangaden, G.J. were previously grouped along with Lactobacillus spp., Leuconostoc spp., and Pediococcus spp. All isolates exhibited high trimethoprim–sulphamethoxazole and ceftazidime MICs (≥128 mg/L) and were inhibited by linezolid, daptomycin, ceftobiprole and tigecycline at 4, 0.12, 2 and 0.12 mg/L, respectively. 16S rRNA gene sequencing in identification of microorganisms. Strain ATCC BAA-781 (CCUG 47861; highlighted by culture-independent approach, and from Weissella confusa, but the majority of dominant bacteria identified belonged to non-pathogenic species. However, the description of W. confusa as a single microbial agent in various infections has demonstrated its role as an opportunistic pathogen. We conclude that low concentrations of VRGPC may be common in the gastrointestinal tracts of children. Integrated Database Network System Concerning W. confusa, several cases reported bacteremia and infections [196][197][198], ... which was a kind of lactic acid bacteria (LAB). Infections with vancomycin‐resistant, gram‐positive cocci are emerging among immuno compromised hosts. We present five cases of Solobacterium moorei bacteremia. Read from thousands of the leading scholarly journals from SpringerNature, Wiley-Blackwell, Oxford University Press and more. Conventional phenotypic tests and commercial identification The 83 isolates were identified by 16S rRNA gene sequencing and according to BLAST comparisons with sequences in the data banks, those strains showing the highest similarities with the isolates were Enterococcus faecium (10), Lactococcus lactis subsp. Check all that apply - Please note that only the first page is available if you have not selected a reading option after clicking "Read Article". pseudomesenteroides 12b et W. cibaria 64, ont augmenté significativement la teneur en composés phénoliques et l'activité antioxydante de jus d'ananas Victoria au cours d'une fermentation de 48h. Antibiotic susceptibility determination by Etest revealed vancomycin resistance and daptomycin susceptibility. The organism was identified as W. confusa by 16S rDNA sequencing. A cross-sectional survey of vancomycin-resistant gram-positive cocci (VRGPC) in the feces of children was initiated after several bacteremic infections with these organisms occurred at our hospital. The MicroScan WalkAway 96 SI, using PC-20 or -29 panels, also did not identify this bacterium, because it is not in their database. An increased percentage of garlic fermenting strains was found during fermentation of som-fak, from 8% at day 1 to 40% at day 5. Current limitations and challenges of these research areas are further discussed. The characteristics of these patients included underlying malignancy (n = 4), presence of a central catheter (n = 6), surgery within the previous 3 months (n = 4) and concomitant polymicrobial bacteraemia (n = 5, 50%). product and the role of garlic as substrate for fermentation. pentosaceus, or a combination of these strains were inoculated into laboratory prepared som-fak with or without garlic. Weissella spp. Bookmark this article. Plates were incubated at 35 degrees C with 5% carbon dioxide and examined at 24, 48, and 72 h. Susceptibilities were determined by broth microdilution. Weissella spp. are inherently resistant to vancomycin. Under appropriate circumstances, clinicians need to request that the laboratory perform susceptibility testing and accurate identification, by nucleic acid sequencing if necessary. nov., detected in food and clinical samples, Bjorkroth, Bjorkroth; Schillinger, Schillinger; Geisen, Geisen, Clostridial liver abscess following blunt abdominal trauma, Abdel‐Haq, Abdel‐Haq; Chearskul, Chearskul; Salimnia, Salimnia; Asmar, Asmar, Recovery of vancomycin‐resistant gram‐positive cocci from children, Green, Green; Wadowsky, Wadowsky; Barbadora, Barbadora, Weissella confusa (basonym: Lactobacillus confusus ) bacteremia, Olano, Olano; Chua, Chua; Schroeder, Schroeder; La Salvia, La Salvia; Hall, Hall, Fatal case of endocarditis due to Weissella confusa, Flaherty, Flaherty; Levett, Levett; Dewhirst, Dewhirst; Troe, Troe; Warren, Warren; Johnson, Johnson, Severe infective endocarditis of native valves caused by Weissella confusa detected incidentally on echocardiography, Shin, Shin; Kim, Kim; Kim, Kim; Kim, Kim; Kook, Kook; Lee, Lee, Identification of gram‐positive cocci and coccobacillary vancomycin‐resistant bacteria, Facklam, Facklam; Hollis, Hollis; Collins, Collins, Weissella confusa : an unexpected cause of vancomycin‐resistant gram‐positive bacteremia in immunocompromised hosts.
