中文摘要 | Kluyvera spp.屬於Enterobacteriaceae族的新菌種,早先被命名為enteric group 8,雖然Kluyvera spp.在不同的臨床檢體中被分離出來,但其臨床特性仍末被完整的建立。我們在此報告一個群突發事件,是由Kluyvera oryocrescens引起的院內血流感染。時間是在1999年1月,在心臟內科病房中四個病人的血液被培養出來K. cryocrescens,所有的分離菌株有完全相同的抗生素感受性,在該病房過去6個月並無此類細菌的感染,該事件的差異性在統計學上有意義。因此,展開調查該群突發以找出感染源,然而,在環境採樣或醫療人員雙手並無發現相同菌株,可能該流行菌株是藉醫護人員雙手傳播,來自共同一個污染的感染源,參考文獻清楚的指出,此種Kluyvera菌株於人類潛在致病性是罕見的,該菌的致病力有待臨床工作者及微生物學家的更多的確認。 |
英文摘要 | Kluyvera, a new genus in the family Enterobacteriaceae, was formerly known as enteric group 8. Although Kluyvera species have been isolated from various clinical specimens, the clinical significance of these isolates has not been well-established. We report here an outbreak of nosocomial blood stream infection caused by K. cryocrescens in January 1999. K. cryocrescens was isolated from blood cultures from four patients in a cardiovascular ward. All of the isolates had identical antibiotic susceptibility pattern. There was no such infection during the previous six months in the ward. The difference in the incidence was statistically significant. Thus, an investigation was carried out to look for the source of the outbreak. However, the same organism was not found from envionmental sampling items nor the hands of medical staffs. It was possible that these epidemic strains were transmitted to patients via the hands of a medical staff and from a contaminated common source. Review of the literature clearly indicates that Kluyvera strains are infrequent but potentially pathogenic in humans. The pathogenicity of this bacterium is being increasingly recognized by clinicians and microbiologists. |
