“…Because it rarely causes infectious disease in humans, there are only a few reports of Lactococcus-associated infection in immunocompromised hosts, such as patients with native valve endocarditis, osteomyelitis, spondylitis, and liver abscess 10. In addition, to date, only 4 cases of Lactococcus-associated PD peritonitis have been reported: L. cremoris -associated PD peritonitis in Belgium, L. lactis in Turkey, L. cremoris in Canada, and L. garvieae in Taiwan 5,6,7,8.…”

Polymicrobial Peritonitis withLactococcus lactisin a Peritoneal Dialysis Patient

Lactococcus lactis (L. lactis) is an important gram-positive bacterium in dairy products. It is a rare cause of opportunistic infections with only four cases of Lactococcus peritoneal dialysis (PD) peritonitis reported in the literature. In Korea, L. lactis infection was first reported in a liver abscess patient in 2010; however, PD peritonitis with Lactococcus has not been reported in Korea. Recently, we experienced a case of Lactococcus-associated polymicrobial PD peritonitis. The patient was initially managed with broad-coverage antibiotics; however, owing to a poor response, the PD catheter was removed and the patient was switched to hemodialysis. We discuss this case and review the literature.

“…cremoris are common starter organisms used worldwide in dairy industry and have been included in the QPS list, despite of isolated human and animal clinical cases involving Lactococcus lactis that have been reported (EFSA, 2012a). A search in PubMed revealed three new human cases, a necrotic abscess in a middle-aged patient (Hadjisymeou et al, 2013), an early postoperative infective endocarditis caused in a 75-year-old man (Rostagno et al, 2013) and an atypical necrotising pneumonia (Buchelli-Ramirez et al, 2013). In the first two studies the authors did not describe the method used for species identification, while a phenotypic approach was used for the taxonomical identification of the strain isolated from necrotising pneumonia.…”

EFSA is requested to assess the safety of a broad range of biological agents 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 to provide a harmonised generic pre-assessment 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 is reviewed and updated periodically. Therefore, the only valid list is the one in the most recently published scientific opinion. The 2013 update reviews previously assessed microorganisms including bacteria, yeasts, filamentous fungi, oomycetes and viruses used for plant protection purposes. All taxonomic units previously recommended for the QPS list had their status reconfirmed. The new notifications since the last QPS update were reviewed. Gluconobacter oxydans and Alphaflexiviridae were assessed for the first time and were recommended for the QPS list. The information of the previous opinion was updated for the taxonomic units on the QPS list. Qualifications for the taxonomic units included in the QPS recommended list were reviewed and confirmed. Filamentous fungi and enterococci were not recommended for the QPS list following updating and reviewing of current scientific knowledge. SUMMARYThe European Food Safety Authority (EFSA) asked the Panel on Biological Hazards (BIOHAZ) to deliver a Scientific Opinion on the maintenance of the list of QPS biological agents intentionally added to food or feed (2013 update). The question included four specific tasks in the terms of reference (ToR).The first required a preparation of an update of the list of biological agents for intentional use in feed and/or food, or as sources of food and feed additives or enzymes and as plant protection products for safety assessment as notified to EFSA Units and/or Scientific Panels such as Pesticides, the Panels on Additives and Products or Substances used in Animal Feed (FEEDAP) and Genetically Modified Organisms (GMO). The list was updated with the notifications received where applicable by EFSA Panels and Units since the last review.The second ToR was concerned with an annual review of the list of biological agents recommended for the QPS list. Where appropriate new taxonomic units should be assessed for their suitability for an inclusion in the QPS list, and taxonomic units previously assessed should be reviewed where new information has become available. The information provided in the previous opinion should be updated where appropriate. The BIOHAZ Panel confirmed all taxonomic units previously re...

“…In particular, L. garvieae has been more broadly associated with fish and dairy consumption, with transmission also reported via contaminated water; conversely, L. lactis is associated primarily with dairy products [8, 9]. Importantly, in many of the reported cases, these patients had underlying gastrointestinal (GI) disease, suggesting a portal of entry [1, 5, 7, 10–13]. While not normally part of the GI microbiome, Lactococcus has been isolated from the intestines of humans [1, 10].…”

A 45-year-old male with a prosthetic aortic valve presented to the hospital with several months of generalized malaise. On admission, he was noted to have anemia of unclear etiology and subsequently became febrile with multiple blood cultures growing Lactococcus garvieae. Inpatient workup was concerning for infectious endocarditis (IE) secondary to Lactococcus. The patient was discharged home with appropriate antimicrobial therapy; however, he was readmitted for persistent, symptomatic anemia and underwent colonoscopy, which revealed innumerable colonic polyps consistent with Familial Adenomatous Polyposis (FAP) that was later confirmed with genetic testing. Surveillance computed tomography (CT) imaging of the aortic repair later demonstrated valve dehiscence with surrounding fluid collection; he underwent redo surgery and was found to have destruction of the aortic annulus and a large pseudoaneurysm. Histopathology of the valve prosthesis confirmed IE. It is suspected that the patient developed Lactococcus IE from enteric translocation. Review of the literature provides several reports of Lactococcus infections in association with underlying gastrointestinal disease, including colorectal cancer. Given this association, we raise the question of whether the diagnosis of Lactococcus IE should evoke suspicion and encourage evaluation for gastrointestinal pathology, as occurs with Streptococcus bovis.
