Leuconostoc spp. used to be considered nonpathogens to human, but human infections have been reported including bacteremia in compromized patients. Leuconostoc spp. may be misidentified as lactobacilli, streptococci, pediococci and enterococci due to atypical biochemical tests. Leuconostoc spp. are intrinsically resistant to vancomycin. We report a case of bacteremia caused by Leuconostoc lactis identified by 16S rRNA sequencing; the isolate was not identified by commercial kits.

5.Evidence on the prevention of postoperative endophthalmitis
Philippine Journal of Ophthalmology 2005;30(2):85-87
CLINICAL SCENARIO: An 82-year-old female with no apparent ocular problems, except fora brunescent cataract, underwent phacoemulsification with intraocular-lens (IOL) implantation. Postoperative medication consisted solely of antibiotic-steroid eye drops. One day after uneventful surgery, the patient developed severe pain, poor vision, and redness in the operated eye. Visual acuity was counting fingers at 1 meter. The eye had ciliary injection, grade 4 flare and cells, a small hypopyon, fibrin extending from the corneal wound, and a mildly edematous cornea. Intraocular pressure (IOP) was 24 mm Hg. Exudates behind the IOL were noted, but visualization was poor. Anterior-chamber and vitreous taps revealed gram-positive cocci. Could the ophthalmologist have prevented this complication? CLINICAL QUESTION: Among patients undergoing cataract extraction, what is the most effective regimen that can reduce the risk of endophthalmitis? SEARCH METHOD: A Medline search was performed using the keywords "endophthalmitis," "cataract," and "prevention." The search was limited to randomized controlled trials (RCT). No studies were found that compared endophthalmitis rates using different perioperative prophylactic measures. Most studies reported used substitute outcome measures such as periocular bacterial load, intraocular penetration of antibiotics, and anterior-chamber contamination. After reviewing the abstracts, only one RCT was considered relevant to the clinical question CITATION: Soto AM, Mendivil MP.

BACKGROUND: The precise identification of Enterococcus gallinarum and E. casseliflavus has assumed additional importance in clinical microbiology due to the intrinsic low-level resistance to vancomycin and the difficulty in differentiating them from E. faecium or E. faecalis, which are frequently found to be clinically significant vancomycin resistant enterococci(VRE). We evaluated the usefulness of Methyl-alpha-D-glucopyranoside(MDG) test for accurate species identification among them. METHODS: A total of 23 enterococci isolates including 18 clinical isolates of VRE from Nov 1997 to Aug 1998 and 5 VRE strains which had previously been reported as E. faecalis (2), E. faecium(2), E. avium(1) carrying vanC were tested for acidification of MDG. MDG test was done using 1% MDG in phenol red broth base and yellow coloration was interpreted as positive after 1 and 2 days of incubation at 35 degrees C. MDG results were compared with species identification by MicroScan Pos Combo type 6 (Dade, US A), motility test, pigment production, and PCR results of vanA, vanB, vanC1, vanC2/C3. RESULTS: Vancomycin resistance of 23 strains were genotyped as 7 strains of vanA, 12 strains of vanC1, 4 strains of vanC2/C3. MicroScan identified 7 vanA VRE as E. faecalis(1) and E. faecium(6), 12 VRE carrying vanC1 as E. faecalis(3), E. faecium(8) and E. avium(1), and 4 VRE carrying vanC2/C3 as E faecalis(3) and E. avium(1). Sixteen vanC VRE strains were all positive for MDG test and only 8(50%) of the 16 strains were motile. Yellow pigment were detected in all 4 vanC2/C3 VRE but only after a careful examination with a prolonged incubation. Seven vanA VRE were all negative in MDG tests, motility test and pigment production. CONCLUSIONS: MicroScan system plus motility and pigment production test was not able to differentiate reliably E. gallinarum and E. casseliflavus from E. faecalis and E. faecium. The MDG test was shown to be superior to motility test in differentiating those from E. faecalis and E. faecium. We conclude that the MDG test should be included for identifcation of VRE.

Leuconostoc species are Gram-positive coccobacilli and are used in dairy products and are intrinsically resistant to vancomycin. Leuconostoc infections are rare in humans, usually occurring in immune-compromised patients. We describe 6 patients with Leuconostoc bacteremia at Dong-A university hospital between 1990 and 2015. One isolate (L. lactis) was identified to species level using 16S rRNA gene sequencing analysis. All patients had underlying diseases and 5 patients underwent procedures that interrupted the normal integumentary defense. Four patients died within 30 days after being identified as carrying Leuconostoc species.

10.Resistance Mechanism and Epidemiology of Vancomycin-resistant Enterococci.
Korean Journal of Clinical Microbiology 2008;11(2):71-77
Since vancomycin-resistant enterococci (VRE) were first isolated in Europe, rates of VRE colonization and infection have risen steadily. Today VRE have emerged as important nosocomial pathogens worldwide; hence, it is crucial to understand the underlying mechanism in the spreading of VRE. This article reviews the mechanism of resistance to vancomycin and global epidemiology of VRE, as well as the current molecular techniques that are being applied to the epidemiological studies of VRE.
