Immun Infekt. 1986 Nov;14(6):199-202.
3715 strains of salmonella have been isolated from various sources from 1976 to 1985. 26 of these isolates have been S. typhi and paratyphi B, 3689 isolates were nontyphoid strains. 7 isolates of S. typhi and S. paratyphi have been isolated from blood cultures. All persons infected with these strains have acquired these organisms in tropical and subtropical areas. In contrast, salmonella gastroenteritis is mainly confined to the intestinal tract. 21 isolates of nontyphoid salmonellae, however, have been isolated from blood cultures. The vast majority of these patients showed compromised host defense mechanisms. Newborn infants up to 3 months are considered particularly vulnerable for bloodstream invasion with nontyphoid salmonellae. Patients with chronic consuming disorders, solid tumors and haematologic malignancies, and the treatment of these ailments with immunosuppressive drugs and corticosteroids predisposes patients for extraintestinal spread of an enteric salmonella infection. Corticosteroid therapy seems to be particularly responsible for a fulminant course of the disease and poor outcome of the infection.
1976年至1985年期间,从各种来源分离出3715株沙门氏菌。其中26株为伤寒沙门氏菌和副伤寒乙杆菌,3689株为非伤寒菌株。从血培养中分离出7株伤寒沙门氏菌和副伤寒沙门氏菌。所有感染这些菌株的人都是在热带和亚热带地区感染的。相比之下,沙门氏菌性肠胃炎主要局限于肠道。然而,从血培养中分离出21株非伤寒沙门氏菌。这些患者绝大多数显示出宿主防御机制受损。3个月以下的新生儿被认为特别容易受到非伤寒沙门氏菌的血流侵袭。患有慢性消耗性疾病、实体瘤和血液系统恶性肿瘤的患者,以及用免疫抑制药物和皮质类固醇治疗这些疾病,会使患者易发生肠道沙门氏菌感染的肠外传播。皮质类固醇治疗似乎特别容易导致疾病的暴发性病程和感染的不良结局。
