The rare yeast species Lodderomyces elongisporus, Kodamaea ohmeri, Cyberlindnera fabianii, and Wickerhamomyces anomalus are increasingly implicated in severe mycoses in immunocompromised patients. This study aimed to assess the prevalence of uncommon yeast species in Côte d'Ivoire.
The yeast isolates from superficial samples, mainly vaginal swabs, were collected at the Pasteur Institute of Abidjan in a study on the molecular epidemiology of clinical yeast species. Identification relied on MALDI-TOF MS and ITS sequence analysis. Antifungal susceptibility testing was performed using the CLSI method.
Of the 315 strains analysed from 227 outpatients, 14 belonged to 4 uncommon species: Lodderomyces elongisporus, Kodamaea ohmeri, Cyberlindnera fabianii, and Wickerhamomyces anomalus. None exhibited elevated fluconazole, amphotericin B, caspofungin, ketoconazole, or flucytosin MIC.
The presence of these rare yeasts represents a risk in immunocompromised people. Their adequate and timely identification is a priority. Overall, enhancing the mycoses diagnostic capacities in Côte d'Ivoire, and more generally in African clinical laboratories with limited resources is a critical aim.
罕见的酵母物种长孢拟内孢霉、大毛霉、法尼拟内孢霉和异常汉逊酵母越来越多地与免疫功能低下患者的严重真菌感染有关。本研究旨在评估科特迪瓦罕见酵母物种的流行情况。
从阿比让巴斯德研究所的浅表样本(主要是阴道拭子)中收集酵母分离物,用于研究临床酵母物种的分子流行病学。鉴定依赖于 MALDI-TOF MS 和 ITS 序列分析。使用 CLSI 方法进行抗真菌药敏试验。
在对 227 名门诊患者的 315 株菌株进行分析后,有 14 株属于 4 种罕见物种:长孢拟内孢霉、大毛霉、法尼拟内孢霉和异常汉逊酵母。没有一株表现出氟康唑、两性霉素 B、卡泊芬净、酮康唑或氟胞嘧啶 MIC 升高。
这些稀有酵母的存在对免疫功能低下的人构成了风险。及时对其进行充分鉴定是当务之急。总的来说,提高科特迪瓦乃至更广泛的资源有限的非洲临床实验室的真菌病诊断能力是一个关键目标。
