Candidemia remains a major cause of morbidity and mortality in the health care environment. The epidemiology of Candida infection is changing, mainly in relation to the number of episodes caused by species C. non-albicans. The overall objective of this study was to evaluate the frequency of yeasts of the genus Candida, in a four-year period, isolated from blood of pediatric patients hospitalized in a public hospital of the city of São Paulo, Brazil. In this period, yeasts from blood of 104 patients were isolated and, the identified species of Candida by phenotypic and genotypic methods were: C. albicans (39/104), C. tropicalis (25/104), C. parapsilosis (23/104), Pichia anomala (6/104), C. guilliermondii (5/104), C. krusei (3/104), C. glabrata (2/104) and C. pararugosa (1/104). During the period of the study, a higher frequency of isolates of C. non-albicans (63.55%) (p = 0.0286) was verified. In this study we verified the increase of the non-albicans species throughout the years (mainly in 2009 and 2010). Thus, considering the peculiarities presented by Candida species, a correct identification of species is recommended to lead to a faster diagnosis and an efficient treatment.
念珠菌血症仍然是医疗环境中发病和死亡的主要原因。念珠菌感染的流行病学正在发生变化,主要与非白色念珠菌引起的感染病例数量有关。本研究的总体目标是评估在四年期间,从巴西圣保罗市一家公立医院住院的儿科患者血液中分离出的念珠菌属酵母菌的频率。在此期间,从104名患者的血液中分离出酵母菌,通过表型和基因型方法鉴定出的念珠菌种类为:白色念珠菌(39/104)、热带念珠菌(25/104)、近平滑念珠菌(23/104)、异常毕赤酵母(6/104)、季也蒙念珠菌(5/104)、克鲁斯念珠菌(3/104)、光滑念珠菌(2/104)和副粗糙念珠菌(1/104)。在研究期间,验证了非白色念珠菌分离株的频率较高(63.55%)(p = 0.0286)。在本研究中,我们验证了非白色念珠菌种类在这些年中有所增加(主要在2009年和2010年)。因此,考虑到念珠菌种类呈现的特点,建议进行正确的菌种鉴定以实现更快的诊断和有效的治疗。
