Analysis of candida infection of urinary tract in elderly patients in the primary hospital

Objective To observe the status of urinary tract infection by candida among elderly patients in primary hospital, and to provide the evidence for clinical diagnosis and treatment. Methods The midstream urine fungal culture and sensitivity test results were retrospectively analyzed in elderly patients with suspected urinary tract fungal infections from January 2010 to June 2012. Results Thirty-four strains of candida were isolated from 176 samples. Twelve strains were from general ward, with the positive rate of 9.4%, and 22 strains were from ICU, with the positive rate of 44.9%(P0.01). The most common strains were candida tropicalis (41.2%), candida glabrata (26.5%) and candida albicans (16.7%).Drug sensitivity test showed that susceptibility to 5-flucytosine, fluconazole, voriconazole, amphotericin B, Itraconazole was 94.1%, 76.5%, 88.2%, 100%, 73.5% respectively. Conclusions Patients in ICU are more susceptible to urinary tract candida infection. Candida tropicalis, candida glabrata and candida albicans are the most common strains. Common azole antifungals appear obvious resistance.
