“…Before the occurrence of Leuconostoc bacteremia, the patient had been treated with several antibiotics, especially ciprofloxacin and metronidazole, but never with vancomycin. Although Leuconostoc infections in patients with previous exposure to other antibiotics have been reported and the role of other antibacterial agents was suggested, it is not clear whether these antibiotics increased the risk of Leuconostoc bacteremia [1,14]. In patients receiving antibiotics that alter the normal gastrointestinal flora, Leuconostoc bacteria might gain access to the blood from the gastrointestinal tract.…”

Leuconostoc bacteremia in a patient with amyloidosis secondary to rheumatoid arthritis and tuberculosis arthritis

Leuconostoc infections are rare and usually occur in immunocompromised patients. This report describes a case of Leuconostoc lactis bacteremia in a patient with coexisting rheumatoid arthritis and tuberculosis arthritis. A disrupted gastrointestinal barrier due to gastrointestinal amyloidosis in long-standing rheumatoid arthritis and tuberculosis arthritis could be a risk factor for Leuconostoc bacteremia. Despite aggressive antibiotic treatment, the patient progressed to septic shock and multi-organ failure. The fatal course might have been caused by rapid progression of gastrointestinal pathology, which could be a risk factor for Leuconostoc bacteremia.

“…Sıklıkla çevrede, bitkilerde, bitkisel ve hayvansal kaynaklı yiyeceklerde yaygın olarak bulunurlar (1). İzolasyonları 1985'lere kadar patojen olarak düşünülmemiş olmakla beraber, son yıllarda özellikle immünsüprese hastalarda, damar içi kateteri olanlarda veya öncesinde vankomisin kullanımı olanlarda infeksiyon etkeni olarak kabul edilmeye başlandı (4,5). Bu infeksiyonlar arasında bakteriyemi, peritonit, plevral ampiyem ve odontojenik infeksiyonlar gibi birçok ciddi infeksiyonlar yer almaktadır (6)(7)(8)(9) …”

Özetİmmünsüpresif tedavi alan akut myelositik lösemili (AML) 53 yaşındaki kadın hastada tekrarlayan bakteriyemi atakları sonrasında, kan kültürü örneğinden Leuconostoc spp. izole edildi. Doğada yaygın olarak bulunan Leuconostoc spp. vankomisine doğal dirençli Gram pozitif bir bakteridir. Enfeksiyonlarda nadiren hastalık etkeni olarak soyutlansa da özellikle immünsüprese hastalarda çeşitli sistemik enfeksiyonlara neden olmaktadır. Bu olgu laboratuvarımızda ilk kez bakteriyemi etkeni olarak Leuconostoc spp izole edilmesinden dolayı sunulmuştur. Anahtar kelimeler: İmmünosüpresyon; kan kültürü; Leuconostoc spp.; vankomisin direnci. AbstractAfter repeated bacteremia attacks in 53-year-old female patient with acute myeloid leukemia (AML) under immunosuppressive treatment, Leuconostoc spp. is isolated from blood culture. Leuconostoc spp. is a vancomycin natural resistant Gram-positive bacterium common in nature. Although it is rarely isolated as an agent in infections, it causes various systemic infections especially in immunosuppressive patients. This case is presented for the first isolation of Leuconostoc spp., as an agent of bacteremia in our laboratory.

“…A fourth species, L. pseudomesenteroides, was considered unsuitable because of a limited body of knowledge on food and feed application and of its (rare) implication in opportunistic infections. Since 2010, a new report of three Leuconstoc infections in patients with malignancy, receiving intensive chemotherapy was published (Ishiyama et al, 2011). In none of the three cases the species was identified.…”

Scientific Opinion on the maintenance of the list of QPS biological agents intentionally added to food and feed (2011 update)

EFSA is requested to assess the safety of a broad range of biological agents (including microorganisms and viruses) in the context of notifications for market authorisation as sources of food and feed additives, enzymes and plant protection products. The qualified presumption of safety (QPS) assessment was developed by EFSA for its own use to provide a generic risk assessment approach applicable across EFSA's scientific Panels, for biological agents notified for intentional use in the whole food chain. The safety of unambiguously defined biological agents at the highest taxonomic unit that is 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 sensible reflected as ‘qualifications’ when a recommendation for the QPS list is given. The list of QPS recommended biological agents is reviewed and updated annually. Therefore, the only valid list is the one in the most recent scientific opinion. The 2011 update reviews microorganisms previously assessed including bacteria, yeasts, filamentous fungi and viruses used for plant protection purposes and confirms the previous recommendations. The anamorph yeast form Phaffia rhodozyma of Xanthophyllomyces dendrorhous was included on the QPS list and to the qualification for yeasts ‘absence of resistance to antimycotics used for medical treatment of yeast infections’, the sentence was added that ‘in the case of Saccharomyces cerevisiae this qualification applies for yeast strains able to grow above 37 °C’. The body of knowledge of filamentous fungi and enterococci was updated and their ineligibility for the QPS list confirmed.
