Oropharyngeal candidiasis is a common occurrence in the course of human immunodeficiency virus (HIV) disease progression. Changes in the clinical severity of oropharyngeal candidiasis and type of Candida species profile may be a reflection of immunological changes in patients. The aim of this study was to undertake a baseline Candida species identification for future reference.
Oral swabs of 267 HIV-infected patients with oropharyngeal candidiasis were cultured and Candida species were identified by API 32 C.
A total of 201 (75.3%) Candida species and 10 (3.7%) non candida fungi were identified. Twenty different Candida species were isolated. Candida albicans was the most prevalent species (68.5%) followed by C. tropicalis (7.4%), C. krusei (6.4%), C. parapsilosis (3.0%) and C. sake (2.5%). Other species ranged from 0.5% to 1.5%. Positive culture was independent of whether patients were on anti-retroviral therapy or not.
Of all Candida isolates, 68.5% were identified as C. albicans. Since other uncommon species were also isolated, it may be necessary in this group of patients to identify Candida species causing severe infections.
口腔念珠菌病是人类免疫缺陷病毒(HIV)疾病进展过程中的常见病症。口腔念珠菌病临床严重程度的变化以及念珠菌种类分布的改变可能反映了患者的免疫变化。本研究的目的是进行念珠菌种类的基线鉴定以供未来参考。
对267例患有口腔念珠菌病的HIV感染患者的口腔拭子进行培养,并通过API 32 C鉴定念珠菌种类。
共鉴定出201种(75.3%)念珠菌和10种(3.7%)非念珠菌真菌。分离出20种不同的念珠菌。白色念珠菌是最常见的种类(68.5%),其次是热带念珠菌(7.4%)、克鲁斯念珠菌(6.4%)、近平滑念珠菌(3.0%)和清酒念珠菌(2.5%)。其他种类的比例在0.5%至1.5%之间。培养阳性与患者是否接受抗逆转录病毒治疗无关。
在所有分离出的念珠菌中,68.5%被鉴定为白色念珠菌。由于也分离出了其他不常见的种类,在这组患者中鉴定引起严重感染的念珠菌种类可能是必要的。
