The present study was conducted over a period of 6 months to determine the Candida species causing candidemia in a neonatal intensive care unit and to analyse the risk factors associated with acquisition of significant fungemia. Speciation of the 19 isolated Candida spp was done by the standard techniques. Antimicrobial susceptibility of these isolates was determined by disc diffusion method against Amphotericin B, Fluconazole, Ketoconozole and 5-Flucytosine. Candida glabrata was the most common species involved (42.1%). Other species isolated were C. tropicalis (31.6%). Calbicans (21.1%) and C.parapsilosis (5.2%). All the isolates were sensitive to Amphotericin B. Resistance to other antigungal agents was seen only in C. globrata. Significant candidemia was seen in 14/19 (72.6%) of neonates. Risk factors found to be associated with significant candidemis in these neonates included intake of multiple broad-spectrum antibiotics (p<0.0001), use of total parenteral nutrition (p<0.045) and ventilators (p<0.0001).
本研究历时6个月,以确定新生儿重症监护病房中引起念珠菌血症的念珠菌种类,并分析与严重真菌血症感染相关的危险因素。采用标准技术对分离出的19株念珠菌进行了菌种鉴定。通过纸片扩散法测定了这些分离株对两性霉素B、氟康唑、酮康唑和5-氟胞嘧啶的药敏性。光滑念珠菌是最常见的感染菌种(42.1%)。分离出的其他菌种有热带念珠菌(31.6%)、白色念珠菌(21.1%)和近平滑念珠菌(5.2%)。所有分离株对两性霉素B均敏感。仅光滑念珠菌对其他抗真菌药物耐药。14/19(72.6%)的新生儿发生了严重念珠菌血症。在这些新生儿中,发现与严重念珠菌血症相关的危险因素包括使用多种广谱抗生素(p<0.0001)、使用全胃肠外营养(p<0.045)和使用呼吸机(p<0.0001)。
