We investigated the cases with Aeromonas bacteremia in terms of clinical and microbiological characteristics, underlying disease and mortality rates. Patients with positive blood cultures were included in this research. Aeromonas bacteremia was diagnosed as at least one positive blood culture for Aeromonas species. The bacteremia was defined as community origin if the onset was in the community or within 72 hours of hospital admission. The others were considered as nosocomial. All bacteria were defined as Aeromonas with conventional method. Species identification was verified by VITEK system. Antibiotic susceptibility tests were analyzed with the disc diffusion, E-test method or VITEK system. Thirty-three patients were diagnosed with bacteremia due to Aeromonas spp. Hematologic and solid tumors were the leading underlying conditions, followed by cirrhosis. Two patients (6%) had community-acquired infections. Aeromonas hydrophila was the most common isolated bacterium. The crude mortality rate was 36%. 12 patients died and 6 deaths and 4 deaths were detected in patients with bacteremia caused by A. hydrophila and Aeromonas sobria respectively. All strains were resistant to ampicillin and more than 90% of the strains were susceptible to trimethoprim-sulfamethoxazole, fluoroquinolone, third generation cephalosporins, and carbapenems. Aeromonas sp. is not a frequent cause of bacteremia however, it may lead to high mortality rates, especially in the immunocompromised hosts and patients with liver cirrhosis. Nosocomial Aeromonas bacteremia is not uncommon in these populations. Broad-spectrum cephalosporins, piperacillin-tazobactam, fluoroquinolones, and carbapenems remain as effective antimicrobial agents for therapy of Aeromonas bacteremia.

土耳其气单胞菌菌血症的临床和微生物学特征。


我们调查了气单胞菌菌血症病例的临床和微生物学特征、基础疾病和死亡率。血培养呈阳性的患者被纳入本研究。气单胞菌菌血症被诊断为至少一种气单胞菌血培养呈阳性。如果菌血症发生在社区或入院 72 小时内，则菌血症被定义为社区起源。其他人被认为是院内的。采用常规方法将所有细菌定义为气单胞菌属。物种鉴定通过VITEK系统验证。采用纸片扩散法、E-测试法或VITEK系统对抗生素敏感性试验进行分析。 33 名患者被诊断为气单胞菌属菌血症。血液肿瘤和实体瘤是主要的基础疾病，其次是肝硬化。两名患者（6%）有社区获得性感染。嗜水气单胞菌是最常见的分离细菌。粗死亡率为36%。死亡12例，嗜水气单胞菌引起的菌血症分别检出6例和4例。所有菌株均对氨苄西林耐药，90%以上菌株对甲氧苄啶-磺胺甲恶唑、氟喹诺酮类、三代头孢菌素、碳青霉烯类敏感。气单胞菌属。虽然它不是菌血症的常见原因，但它可能导致高死亡率，特别是在免疫功能低下的宿主和肝硬化患者中。院内气单胞菌菌血症在这些人群中并不少见。广谱头孢菌素、哌拉西林-他唑巴坦、氟喹诺酮类和碳青霉烯类仍然是治疗气单胞菌菌血症的有效抗菌药物。
