  • Purpose: The purpose of this study was to identify factors influencing Vancomycin-resistant enterococcus infection control among nurses in intensive care units. Method: Data were collected from August 15 to October 14, 2007 from 188 nurses working in intensive care units. The nurses answered a 26 item-questionnaire, which included management of the cohort (14 items), hand washing (6 items) and management of the environment (6 items). Descriptive statistics, t or F test, ANOVA, and multiple regression analysis were used with SPSS PC+ 14.0 to analyze the data. Results: The participant's level of awareness of Vancomycin-resistant enterococcus infection control was 3.87; that of compliance was 3.74. Significant factors influencing the level of compliance with Vancomycin-resistant enterococcus infection control were'the level of the awareness' and 'the type of intensive care unit'. These two variables accounted for 21.0% of variance for compliance with the Vancomycin-resistant enterococcus infection control among the participants. Conclusion: In order to develop a strategy to increase the compliance with Vancomycin-resistant enterococcus infection control, it is necessary to be concerned about 'the level of the awareness', 'the type of intensive care unit;', and 'experiences of caring for patients with Vancomycin-resistant enterococcus'.

  • In this study, a total of 256 samples of retail raw meats (beef, pork and chicken) and sashimi were investigated for the presence of Enterococcus faecalis and Enterococcus faecium. We isolated a total of 117 E. faecalis and E. faecium from the samples, with contamination rates ranging from 18.8% for sashimi samples to 68.8% of chicken samples. E. faecalis was the predominant species recovered from all of the retail raw meats beef (42.2%), pork (42.2%), chicken (65.6%) and sashimi (12.5%). Among 117 isolates, 61 isolates (52.1%) were resistant to tetracycline, 32 isolates (27.4%) were resistant to erythromycin, 23 isolates (19.7%) were resistant to chloramphenicol, 16 isolates (13.7%) were resistant to ripampin, 10 isolates (8.5%) were resistant to gentamycin, 9 isolates (7.7%) were resistant to ciprofloxacin and 1 isolate (0.9%) was resistant to ampicillin and penicillin G. No resistance to amoxicillin + clavulanic acid and vancomycin was observed. Although no strain was resistant to vancomycin, the vanB gene was observed in 9 of 117 of Enterococcus (7.7%) demonstrating potential risk of vancomycin-resistant Enterococcus (VRE). Our results indicate that E. faecalis and E. faecium were highly prevalent in retail raw meats, but most strains were sensitive to tested antibiotics.

  • To evaluate the vancomycin resistance of Enterococcus spp. (VRE) from Saengsik and Sunsik, Enterococcus were isolated and identified from 25 Saengsik and 35 Sunsik samples, and resistance of Enterococcus to other antibiotics was also assessed. Thirty nine Enterococcus, 16 strains from Saengsik, and 23 strains from Sunsik, were ultimately isolated. The most frequently collected Enterococcus isolates in Saengsik were E. casseliflavus and E. hirae, and were E. casseliflavus and E. faecium in Sunsik. However, E. faecalis was not detected in those foods. Minimum inhibitory concentrations of vancomycin against the isolates were below $4\;{\mu}g/mL$ and no strains evidenced profound levels of resistance. The isolates were found to be susceptible to vancomycin with the exception of eight E. casseliflavus and three E. gallinarum. All Enterococcus isolates proved resistant to streptomycin and chloramphenicol. 23% of the isolates were resistant to penicillin; however, all of the isolates were sensitive to tetracycline. Six and 48%, respectively, of the strains from the Saengsik and Sunsik proved resistant to erythromycin. All of E. mundtii and E. hirae isolates from Saengsik, and 20% of E. gallinarum and E. casseliflavus isolates from Sunsik were found to be ampicillin-resistant. All of E. gallinarum, E. casseliflavus, and E. faecium were rifampin-resistant. The antibiotic resistances of Enterococcus were relatively low, and this low vancomycin resistance was similar to that evidenced by Enterococcus isolates obtained from the other foods. However, there may be a need for some review of the accepted antibiotics criteria for Enterococcus and VRE in ready-to-eat foods.

  • To evaluate the antibiotic risk of $Enterococcus$ in fermented soy paste, $Enterococcus$ spp. were isolated and identified from 31 $Cheongkukjang$ and 17 $Doenjang$, samples. Exactly 123 $Enterococcus$ spp., 119 from $Cheongkukjang$ and four from $Doenjang$, were ultimately isolated. The most frequently collected $Enterococcus$ isolates in $Cheongkukjang$ were 69 strains of $E.$ $faecium$ and 20 strains of $E.$ $faecalis$. All four $Enterococcus$ spp. from $Deonjang$ were identified as $E.$ $faecium$. All isolates were sensitive to ampicillin, chloramphenicol, penicillin, and tetracyclin $E.$ However, they showed broad spectra from sensitivity to resistance to erythromycin, ripampin, and streptomycin. Vancomycin minimum inhibition concentration (MIC) of $Enterococcus$ spp. from $Cheongkukjang$ ranged from 0.25 to 8 ${\mu}g/mL$. Almost all strains were sensitive to vancomycin, but eight strains showed intermediate resistance to vancomycin. Seventeen strains showing the highest MIC of 8 ${\mu}g/mL$ among all isolates were evenly distributed among $E.$ $faecalis$, $E.$ $faecium$, $E.$ $gallinarum$, and $E.$ $casselifalvus$, in which the strong resistant genes of $van$A and $van$B for vancomycin were not detected. Overall antibiotic resistance of $Enterococcus$ isolates was relatively low and particularly low vancomycin resistance was similar to those of $Enterococcus$ isolates obtained from other foods. Therefore, the antibiotics resistance of $Enterococcus$ and especially vancomycin-resistant $Enterococcus$ spp. from $Cheongkukjang$ and $Doenjang$, is not hazardous.

  • To evaluate the antibiotic resistance of Enterococcus from salad and sprout, Enterococcus were isolated and identified from 47 salad samples and 37 sprout samples, and then their antibiotic resistances were analyzed. Ninety five Enterococcus, 41 strains from salad and 54 strains from sprout, were ultimately isolated. The frequent Enterococcus in salad and sprout were E. gallinarum, E. faecalis, E. faecium, E. hirae, and E. avium. Minimum inhibitory concentrations of the isolates for vancomycin were below $4{\mu}g/mL$, which were not high levels of resistance. All Enterococcus proved to be resistant to streptomycin and chloramphenicol. Twenty two percentage of the isolates were resistant to penicillin, however, almost the isolates were sensitive to tetracycline. Eighteen percentage of the isolates were resistant to erythromycin. All E. faecium and E. faecalis were found to be ampicillin-resistant, and seven E. faecalis and five E. faecium were resistant to rifampicin. Overall antibiotic resistances of Enterococcus isolates were relatively low and low resistance to vancomycin was similar to those evidenced by Enterococcus isolated from the other foods. Therefore, there may be no special risk from the antibiotics resistances of Enterococcus and especially vancomycin-resistant Enterococcus from the fresh-cut salads and the sprouts.

  • This study aimed to investigate the effect of Hwanglyeonhaedok-tang on the clearance of vancomycin-resistant Enterococcus (VRE) colonization in a patient with traumatic subarachnoid hemorrhage and subdural hematoma. A 73-year-old man who was diagnosed with traumatic subarachnoid hemorrhage and subdural hematoma with isolation of VRE colonization was administered Hwanglyeonhaedok-tang and followed up with a rectal swab VRE culture every week. After treatment with Hwanglyeonhaedok-tang, VRE colonization was no longer detected. This case report proved that Hwanglyeonhaedok-tang could be an effective treatment for clearance of VRE colonization in a patient with traumatic subarachnoid hemorrhage and subdural hematoma.

  • The aim of this study was to evaluate the effects of the photosensitizer photogem with light-emitting diode (LED) on vancomycin-resistant enterococci (VRE). Two VRE strains isolated from the feces of patients. that was identificated Enterococcus faecium (vanA) and Enterococcus gallinarum (vanC1) using traditional biochemical tests and confirmed VRE genotyping from using polymerase chain reaction. In addition, three strains were used Enterococcus. faecalis CDC-286 (vanA), E. faecalis CDC-583 (vanB) and E. gallinarum CDC-42 (vanC1). To examine the antimicrobial effect of photogem mediated photodynamic therapy (PDT) against, CFU quantification and Disk diffusion antimicrobial susceptibility test were evaluated. The effects of Photodynamic therapy was not associated with genotype. Photogem mediated PDT perfectly inhibited the colony formation of E. faecalis CDC-286. The number of viable bacteria decreased greatly after PDT application with photogem $50{\mu}g/mL$ and energy density of $15J/cm^2$. The diameter of inhibition zone was increased to after PDT more than before PDT. The case of vancomycin disc on E. faecalis CDC-583 and E. galinanum-Patient were changed from resistant to intermediate resistant, from intermediate resistant to susceptable. These results demonstrate that lethal photosensitization of VRE can be achieved using photogem plus 630 nm LED irradiation.

  • The treatment of invasive infections caused by multidrug-resistant vancomycin-resistant enterococci (VRE) is challenging, particularly in pediatric patients with underlying medical conditions. Newer antibiotics used to treat VRE infections in pediatric patients are insufficiently studied. This report presents the case of a 6-month-old infant who underwent heart-lung transplantation and was successfully treated with a combination of daptomycin and tigecycline for recurrent VRE bacteremia shortly after the discontinuation of linezolid.

  • Raw milk samples, and cow and chicken intestines were tested to isolate vancomycin-resistant, gram-positive bacteria. From these samples, we isolated seven vancomycin-resistant Streptococcus equinus, two vancomycin-resistant viridans Streptococcus and two vancomycin-resistant Enterococcus faecium. The MICs of several antibiotics, including vancomycin, against these strains were tested. Seven isolates of S. equinus showed high level resistance to vancomycin and teicoplanin (>100 $\mu$ g/mL). The cell wall thickness of these strains was compared with that of the sensitive strain by TEM and no differences were obserbed between these strains. We compared the strains of vancomycin-resistant Streptococcus equinus using PCR with Microbial Uniprimer Kit. We concluded that it is necessary to combine other methods in order to cluster and identify all isolates of S. equinus.

  • The rates and severity of Clostridium difficile infections, including pseudomembranous colitis, have increased markedly. However, there are few effective treatments for refractory or recurrent C. difficile infections and the outcomes are poor. Fecal microbiota transplantation is becoming increasingly accepted as an effective and safe intervention in patients with recurrent disease, likely due to the restoration of a disrupted microbiome. Cure rates of >90% are being consistently reported from multiple centers. We cured a case of severe refractory C. difficile infection with fecal microbiota transplantation in a patient colonized by vancomycin-resistant enterococcus.
