Kimchi-derived probiotic found to promote binding and excretion of intestinal nanoplastics A lactic acid bacterium isolated from kimchi may help promote the removal of nanoplastics from the body by binding to them in the intestine. Nanoplastics are ultrafine plastic particles measuring…

#leuconostoc R to tmp/smx, fosfomycin appears to be common. Most isolates S to erythro, clinda, tetracycline, minocycline, chloramphenicol. linezolid w/ higher MIC htan strep. Dapto active

#leuconostoc abx susceptibility testing is crucial as naturally R to glycopeptides due to production of peptidoglycan precursors ending in D-ala D-lactate. usually S to penicillin G & amp (although higher MIC than strep. CM have good activity but R has been documented

#leuconostoc risk fact: previous abx (Vancomycin), presence of intravascular devices, underlying GI disease

#leuconostoc sp appear to be normal colonizers of GI tract which could be initial portal of entry. Can cause bacteremia (catheter related), IE, pulm infection, meningitis, brain/liver abcess, OM, can affect immunocompetent & IC hosts

#leuconostoc distinguishing features: Vancomycin resistance, negative reaction for PYR & leucine aminopeptidase, lack of gas production from glucose. L lactis is most common sp in human infections

#Leuconostoc gram-positive facultative anaerobic coccus or coccobacillus, catalase and oxidase negative, which grow in pairs and chains, often found in plants, dairy. sporadic pathogens. can phenotypically resemble strep, enterococc, pediococcus lactococcus
