临床真菌实验室常规培养通常用4周或更长时间以便尽可能地分离出生长缓慢的真菌。本文表明:对于多数标本延长孵育时间几乎不能增加分离率,但却极大地增加了实验室的负担。为了发现常规真菌培养的最佳时间,Duke大学医学中心临床真菌实验室,从1992年1～6月先后对1207例病人,共2173份标本进行培养分析。多数标本(80%)来自住院病人,其中过半数病人住院1周以上。
Clinical fungal laboratory routine culture is usually 4 weeks or longer in order to isolate the slow-growing fungi as much as possible. This article shows that extending the incubation time for most of the specimens can hardly increase the isolation rate, but greatly increases the burden on the laboratory. In order to find out the best time for routine fungal culture, Duke University Medical Center clinical fungal laboratory, from January to June 1992 has 1207 patients, a total of 2173 specimens for culture analysis. Most specimens (80%) came from hospitalized patients, of whom over half were hospitalized for more than 1 week.
