“…Species were generally considered non-pathogenic and of little significance in clinical microbiology until several occurrences of Leuconostoc infections were reported in the literature. It is an emerging pathogen responsible for many infections (15,16). Standard phenotypic methods were used in this research to identify isolates.…”

“…Leuconostoc species exist in fermented foods and beverages industries due to their role in fermentation (sauerkraut, milk, cereals fermented drinks, and palm wine) (23). This bacterium is found naturally in plants and vegetables (16). Humans may be infected by exposure to unpasteurized products or by contact with vegetables or plants (24).…”

“…The main dangers to the consumer are the presence of antibiotic residues and bacteria resistant to antibiotics (27). Although they are resistant to vancomycin, Leuconostoc are sensitive to erythromycin and clindamycin (16). A recent study (28) reported Leuconostoc endocarditis and suggested poor dental health or odontogenic infections to be the major source.…”

Purpose: Endodontic infections are polymicrobial. This study was undertaken to characterize and perform an antimicrobial susceptibility test on Leuconostoc sp. isolated from acute endodontic infections in Ouagadougou, Burkina Faso. Methods:A cross-sectional descriptive study was conducted at Ouagadougou, Burkina Faso, from June to October 2014. A questionnaire form was used to collect the clinical data. Biochemical standard techniques were used to isolate bacteria, and identification was made by API 20 Strep gallery. Antimicrobial susceptibility was carried out by the diffusion method on a solid medium. Results:The age group of 19-40 years (67.7%) was more significant among the 93 patients included in the study. Acute cellulitis was accounted for 66.7% while acute apical periodontitis was observed in 33.3% of cases. Two exudate samples were positive to Leuconostoc sp. showing 100% sensitivity to lincosamides (lincomycin and clindamycin). On the other hand, they were 100% resistant to trimethoprimsulfamethoxazole, 50% resistant to the macrolides (spiramycin and erythromycin), and the 3 rd generations of cephalosporins (cefotaxime, cefuroxime, cefixime, and ceftriaxone). Conclusion:Leuconostoc sp. was associated with acute endodontic infections and an opportunistic pathogenic bacterium. The primary objective of the treatment of endodontic infection is to eliminate biofilms by a chemomechanical treatment. Dentists must avoid the overuse of antibiotics to prevent the emergence of antibiotic-resistant bacterial strains.

EFSA is requested to assess the safety of a broad range of biological agents in the context of notification for market authorisation as sources of food and feed additives, food enzymes and plant protection products. The qualified presumption of safety (QPS) assessment was developed to provide a harmonised generic preassessment to support safety risk assessments performed by EFSA's scientific Panels. The safety of unambiguously defined biological agents (at the highest taxonomic unit appropriate for the purpose for which an application is intended), and the completeness of the body of knowledge are assessed. Identified safety concerns for a taxonomic unit are, where possible and reasonable in number, reflected as 'qualifications' in connection with a recommendation for a QPS status. The list of QPS recommended biological agents was reviewed and updated in the current opinion and therefore becomes the valid list. The 2016 update reviews previously assessed microorganisms including bacteria, yeasts and viruses used for plant protection purposes following an Extensive Literature Search strategy. The taxonomic units related to the new notifications received since the 2013 QPS opinion, were periodically evaluated for a QPS status and the results published as Statements of the BIOHAZ Panel. Carnobacterium divergens, Lactobacillus diolivorans, Microbacterium imperiale, Pasteuria nishizawae, Pediococcus parvulus, Bacillus flexus, Bacillus smithii, Xanthomonas campestris and Candida cylindracea were recommended for the QPS list. All taxonomic units previously recommended for the 2013 QPS list had their status reconfirmed as well their qualifications with the exception of Pasteuria nishizawae for which the qualification was removed. The exclusion of filamentous fungi and enterococci from the QPS evaluations was reconsidered but monitoring will be maintained and the status will be re-evaluated in the next QPS Opinion update. Evaluation of bacteriophages should remain as a case-by-case procedure and should not be considered for QPS status. Acknowledgements: The BIOHAZ Panel wishes to thank the EFSA staff member: Mirena Ivanova for the support provided to this scientific output.

Bacteremia by Leuconostoc mesenteroides in an immunocompetent patient with chronic Chagas disease: a case report

et al. 2018

View full text Add to dashboard Cite

BackgroundThe Leuconostoc mesenteroides are members of the Streptococcae family and currently has been recognized as potential pathogens. This case describes a bacteremia caused by L. mesenteroides in an immunocompetent patient affected by Chagas disease.Case presentationA 67-year-old female patient with chagasic megaesophagus and megacolon was submitted to a Heller myotomy for achalasia in 2000 and endoscopic dilatation in 2015. Patient was admitted to the Nutrology Ward in May 2016 with protein-calorie malnutrition associated with achalasia and receiving enteral nutrition. In July 2016, the patient underwent a Serra-Doria surgery. In the third postoperative day she presented an important abdominal distension. She was submitted to a new surgical intervention, and then a terminal ileum perforation was detected, leading the surgeon to perform an enterectomy with side-to-side anastomosis. The next day after the surgery (4th postoperative day) the patient presented a decreased level of consciousness (Glasgow coma scale = 8), hypotension and hypoxemia. In two samples of blood cultures there was growth of Leuconostoc mesenteroides. Susceptibility pattern was evaluated by the diffusion disk method. The microorganism was susceptible to penicillin, ampicillin, chloramphenicol, erythromycin, and fluoroquinolones, but resistant to rifampin, tetracycline, vancomycin and teicoplanin.ConclusionWe concluded that infections caused by L. mesenteroides is serious and should be considered not only in settings of immunosuppression and prolonged antimicrobial use, but also in immunocompetent patients undergoing surgeries involving the gastrointestinal tract.
