To determine the distribution of etiologic agents of fungemia in San Martin Hospital, La Plata, we retrospectively studied 81 consecutive episodes of fungemia, diagnosed in 46 adults and 35 preterm newborn (PNB) hospitalized from November 1998 to August 2001. The diagnosis was achieved by blood culture obtained by venipuncture and by catheter aspiration and was processed using BactAlert and lysis-centrifugation technique. Isolated yeasts were identified employing API 32C system and additional tests. Candida parapsilosis (28.4%), C. albicans (25.9%) and C. tropicalis (25.9%) were predominant as etiological agents (80%). Other species of Candida (C. pelliculosa, C. kefyr and C. guillermondii), Malassezia pachydermatis, Cryptococcus neoformans and Histoplasma capsulatum were recovered in low percentage (each one < or = 7%). C. parapsilosis was predominant as causative agent among PNB male (47.4%), C. albicans among adult women (41.7%) and C. tropicalis among adult men (32.3%). The species of Candida (C. parapsilosis, C. tropicalis and C. albicans) were predominant as etiologic agents of fungemia, with a different distribution in the episodes which occurred in adults and PNB patients, and also according to gender in both groups.
为确定拉普拉塔圣马丁医院真菌血症的病原体分布情况,我们回顾性研究了1998年11月至2001年8月期间住院的46名成人和35名早产新生儿(PNB)中连续发生的81例真菌血症病例。诊断通过静脉穿刺和导管抽吸获取血培养物,并采用BactAlert和裂解离心技术进行处理。分离出的酵母使用API 32C系统及其他测试进行鉴定。近平滑念珠菌(28.4%)、白色念珠菌(25.9%)和热带念珠菌(25.9%)是主要病原体(占80%)。其他念珠菌属(膜璞念珠菌、克柔念珠菌和季也蒙念珠菌)、厚皮马拉色菌、新生隐球菌和荚膜组织胞浆菌的检出率较低(各<或 = 7%)。近平滑念珠菌是PNB男性中主要的病原体(47.4%),白色念珠菌是成年女性中主要的病原体(41.7%),热带念珠菌是成年男性中主要的病原体(32.3%)。念珠菌属(近平滑念珠菌、热带念珠菌和白色念珠菌)是真菌血症的主要病原体,在成人和PNB患者发生的病例中分布不同,且在两组中均因性别而异。
