肠球菌感染长期来未受重视,并且该菌是否致病也尚有争议。近年许多资料说明,肠球菌的毒力与感染率均有增高,约占医院内感染的9%,是医院内感染中第三位常见的菌种。在大面积烧伤及胸外科病人中,肠球菌菌血症是一严重的、有时是致命的并发症。目前已知有四种肠球菌是致病的。其中85～90%是粪肠球菌(E.faecalis)。Maki等报告,外科病人中约77%的肠球菌感染是医院内感染;多半是与留置导管有关,如留置导尿管,静脉内导管等。该组153例外科病人中,有24例发生了与导管有关的肠球菌菌血症。中心静脉留置导管受肠球菌污染后,不仅可引起菌血症,也可引起血栓性静脉炎。
Enterococcal infection has not been valued for a long time, and whether the disease is also controversial. In recent years, many data indicate that the virulence and infection rate of enterococci have increased, accounting for about 9% of hospital infections, is the third common hospital infection in the species. Enterococci bacteremia is a serious and sometimes fatal complication in large area burn and thoracic patients. Four types of enterococci are known to be pathogenic. 85-90% of them are E. faecalis. Maki et al. Reported that about 77% of enterococcal infections in surgical patients were nosocomial infections; most were associated with indwelling catheters such as indwelling catheters and intravenous catheters. Of the 153 surgical patients in this group, 24 had duct-related enterococcal bacteremia. Central venous catheter catheter contamination by Enterococcus, not only can cause bacteremia, can also cause thrombophlebitis.
